Protargol storage after opening - how to store protargol drops?

general characteristics

As a rule, the product is pre-ordered at a pharmacy that has a laboratory.
You can prepare the medicine in 10-30 minutes, depending on the pharmacist’s workload. The pharmacist assigns the client a day and time when he needs to come in for ready-made Protargol. Storage after opening is also discussed as this is a very important point that cannot be ignored. Since the silver solution completely loses its healing properties within two weeks and becomes completely unsuitable for use, preparing it in advance is simply pointless. The mechanism of operation of protargol is simple. The drug envelops the mucous membrane of the nasal passages and constricts blood vessels. The active substance has a detrimental effect on fungi and pathogens.

The medicine has been used to treat the common cold for several decades. Its popularity is due to its low price and high efficiency.

After opening, the drug can be stored for no more than 2 weeks, despite the fact that some doctors give protargol for a whole month. After two weeks, the product loses most of its beneficial substances and gradually becomes useless, regardless of where protargol is stored. After opening, the medicine must be placed in a cool, dark place. A refrigerator is ideal.

Today, Protargol is often prescribed when purulent processes are detected, despite the fact that pharmaceutical companies have filled pharmacy counters to capacity with modern drugs.

What does Protargol treat?

Most often the medicine is prescribed for the following diseases:

Otitis media. Most often, this disease is treated with antibiotics, and protargol is prescribed as an additional therapy to quickly eliminate inflammation. Doctors prescribe this remedy for purulent otitis, as the medicine prevents the further spread of infection.
Conjunctivitis. An infectious disease that affects the mucous membrane of the eye. The disease manifests itself in increased tearing, pain and burning. If the patient’s condition is severely advanced and pus appears in the eyes, then ophthalmologists recommend Protargol in this case to wash the mucous membrane and reduce inflammation.
Sinusitis. The pathology often occurs with the release of purulent mucus from the nasal ducts. The medicine effectively eliminates fungi and bacteria, which significantly speeds up recovery.
Cystitis. In this case, Protargol is used for periodic lavage of the ureter.

In order not to reduce the effectiveness of protargol, the shelf life after opening should be no more than 2 weeks. Cases of severe poisoning can be prevented only by keeping the medicine out of the reach of children.

Rules for use and storage

Under no circumstances should the product be diluted at home, since this manipulation requires special measuring instruments, pharmaceutical education and skills. When diluting, it is very important to maintain the correct concentration of the powder, since a weak solution will not give the expected result, and a strong solution will lead to burns on the mucous membrane.

It is also not recommended to purchase the drug without a doctor’s prescription when trying to treat yourself. In each case of the disease, the concentration of the drug and the frequency of administration may differ. That is why most pharmacies do not risk selling the product without a medical prescription. Making the solution will not take much time from the pharmacist; in just 20-30 minutes you can pick up your order.

Since Protargol is an unstable drug and decomposes quickly, it is important to store it correctly and use it rationally:

Drops are stored in a cool place, protected from light.
The prepared solution should be kept in its original packaging - a bottle made of thick dark glass.
The bottle should not be left in the light, and after each use it should be hidden in the ideal place to store most medications - the refrigerator.

If professional experience allows you to prepare the solution at home, then you need to have on hand glassware with thick walls and a spoon made of the same material. The water must be distilled, purchased at a pharmacy. The finished solution is poured into a dark glass bottle and tightly closed with a lid. In order not to get confused about the shelf life, a label should be affixed to the packaging with the date of manufacture, time and percentage of concentration of silver powder.

It is recommended to store the dry product purchased at the pharmacy in a cool, moisture-free place. If the powder gets wet, it must be thrown away, regardless of when it was purchased.

If the medicine has been stored in a warm place for several hours or may have been exposed to direct sunlight, the medicine must be discarded. In this case, the silver precipitates and then dissolves again. This medication will not have a positive effect.

Pharmacists recommend storing ready-made Protargol for 2 weeks, while Sialor can be kept open a little longer. The medicine is dispensed by a pharmacist in the form of a kit for self-preparing drops. Doctors equally recommend Sialor or Protargol. What is better, the instructions can tell you.

If we compare both medications, Protargol has a shorter shelf life. Sialor is allowed to be stored and actively used for a whole month. The effect of both products is the same, so for long-term use it is better to take Sialor. How to store the prepared solution is described in detail in the instructions that come with each kit. Like Protargol, the prepared solution of Sialor should be placed in the refrigerator, away from children. When the medicine becomes unsuitable for use, a cloudy sediment forms on the walls, and the solution becomes heterogeneous.

How to store protargol

Prepared silver-based solutions should be stored in a dark, cool (+4C -+8C) place, always in the manufacturer’s packaging. Do not leave drops on illuminated window sills or in places with bright lighting. This will lead to chemical reactions, as a result of which the composition will quickly lose quality.

The shelf life of Protargol after opening the bottle, if stored in a dark, cool place, does not exceed 1 month. In this case, it is advisable to place it in an opaque container, and after each use you should tightly close the container with a stopper and screw on the lid.

When the bottle is unsealed, the date is indicated on it, so that later you will know how long protargol can be stored after opening.

The drug, which is stored in powder form, should be protected from dampness and moisture entering the container. If this happens, it is thrown away without regret, regardless of the date the container was opened.

People with pharmaceutical experience who make protargol on their own need to acquire a special glass spoon and thick glassware. When taking the powder from the bottle for subsequent mixing with distilled water (water for injection is also suitable), the spoon and utensils must be dry and sterile.

The prepared solution is poured into a sterile dark glass container, closed tightly, and then sent to the refrigerator. In this case, the label indicates not only the date of manufacture of the solution, but also its concentration.

Protargol should be stored out of the reach of children.

If during storage the color of the contents of the container begins to change, use of the drug should be discontinued.

Dosage calculation

Before administering the drug, it should be thoroughly shaken and warmed in the palms of your hands to room temperature. Protargol is used only topically. Under no circumstances should you drink this medicine. Silver is not as harmless as it may seem at first glance, so you need to instill it into your eyes, ears or nose very carefully, observing the dosage. The wrong amount of the drug can settle on internal organs and cause serious harm to the body.

Dosage:

The drug, diluted in the required concentration, must be instilled 1-2 drops 3 times a day.
When treating purulent otitis or sinusitis, doctors use a 2% solution. It is important to observe the dosage, since such a concentration is effective, but very dangerous.
For problems of the genitourinary system, Protargol 2% solution is also prescribed. Flushing the ureter and bladder is difficult and dangerous at home. First, a catheter is inserted into the urinary canal to remove accumulated urine. Then, using a special wide syringe, the solution is injected until the urge begins. The procedure ends with disconnecting the tube and syringe and removing the fluid. This not the most pleasant, but very effective manipulation is carried out 10 times in one day. If there is inflammation, pain may occur. If rinsing is performed incorrectly, the patient may feel pain, blood and fever.

Protargol can be prescribed to children. In case of rhinitis, the child needs to rinse the nose, thoroughly clear it of mucus, and then drip protargol in the dosage prescribed by the doctor. The drug is often used to treat the upper respiratory tract in children.

Protargol is recommended for use in children under 6 years of age. It can also be used for prevention. In maternity hospitals, silver solution is often instilled into the eyes of newborns. This procedure helps prevent eye suppuration in babies immediately after birth.

How to store Sialor

Sialor is used to prepare protargol at home. The kit includes everything you need for this, including distilled water and detailed instructions for diluting the silver ion powder.

You can also ask your pharmacist how to store the prepared Sialor solution and powder in a printed container. Usually this is 30 days from the moment of opening, subject to temperatures up to +25C and humidity not higher than 60%.

After the powder is diluted with water, it is kept exclusively in the refrigerator.

General description of the drug Protargol

Protargol

The drug works as follows. When it gets on the damaged mucous membrane, it forms a special film, and also promotes vasoconstriction and prevents the proliferation of microbes, fungi and bacteria. Its effect on viruses is limited.

This drug has been known for a very long time. It is loved for its effectiveness and affordable price. Protargol is widely used for various purulent inflammations to this day, although a huge number of more modern antiseptic drugs have appeared.

Indications are inflammatory diseases of the mucous membranes:

Otitis. Protargol is used for various types of otitis to relieve the inflammatory process from the tissues of the ear. Most often, this disease is treated with antibiotics, and Protargol is an auxiliary measure. It is also used for purulent otitis media. It does not allow the infection to penetrate further into the ear canal.
Conjunctivitis. With this disease, the eyes suffer, they water, fester, there is a feeling of sand in the eyes, pain, and increased sensitivity to light. Moreover, most often both eyes are affected at once. A doctor may prescribe Protargol for instillation into the eyes to kill the pathogenic environment, stop inflammation, and wash the eyes of pus.
Sinusitis. With sinusitis, discharge of pus from the nose is quite common. Protargol, when instilled into the nose, destroys fungus and bacteria. However, it does not have any vasoconstrictor properties, so you cannot expect an immediate effect.
Cystitis. With cystitis, the mucous membrane of the bladder and urethra becomes inflamed. In this case, the patient experiences severe pain, the process of urination is disrupted. In this disease, Protargol is used to wash the urinary canal and relieve inflammation.

Storage of the drug

How to properly store Protargol

As mentioned above, it is impossible to dilute Protargol at home and it is not stored for long, up to a month, if all the rules are followed. Buying powder and storing it at home is also pointless unless you are an experienced pharmacist. The entire procedure requires precise weighing and concentrations.

It is also not recommended to order the drug without a doctor's prescription, since to produce it you need to know the concentration. Most likely they won’t sell it to you without a prescription. It is done quite quickly and is inexpensive. You can pick up the finished solution within half an hour after ordering.

It’s not for nothing that Protargol is not produced in finished form. The solution is unstable and must be made correctly and then stored correctly. Only in this case can you count on a positive effect.

So, let's look at a few rules for storing Protargol at home:

Store the drug only in a cool place away from strong light. It’s not for nothing that pharmacies sell it in bottles made of dark thick glass. You can’t leave it on the windowsill so you don’t forget to put it in at night. It must be tightly closed and put in a dark place. Best in the refrigerator.
If you do have some experience and make the drug at home yourself, use only sterile glass containers and boiled or distilled water. The stirring spoon should also be made of glass. The prepared solution can only be poured into dark bottles and stored in the refrigerator on the bottom shelf.
Dry powder should also be stored in a dark and cool place, protected from moisture. If the powder gets wet, it needs to be thrown away. It is no longer possible to prepare a drug from it.
If you left the drug for a long time in a warm place or in the light, it will also have to be thrown away. The silver simply precipitates and then dissolves. Such treatment will not give any positive effect.

Pharmacists will tell you the shelf life. Typically, Protargol is recommended to be stored for 10 to 30 days. After the expiration date, do not use the drug under any circumstances. If the course of treatment needs to be continued, order a fresh solution from the pharmacy.

The unsuitability of a drug can be determined by its appearance. A silvery sheen will appear on the walls of the bottle, and the solution itself will lose its homogeneity.

Remember to close the solution bottle tightly after use and shake before use.

Conditions for storing the drug in pharmacies and clinics

The shelf life of medicine prepared in a pharmacy is 30 days.

Accordingly, it is not prepared in advance, but only at the request of the buyer. There is no need to store it in large quantities. Storing the finished solution until it is purchased is only permissible in the refrigerator at a temperature of +4 ... +8 ° C, in a common room. It is acceptable to store Protargol next to other medications. The refrigerator must have two thermometers - on the top and bottom shelves - to monitor the storage temperature. The room must have a working hood and a hygrometer to control humidity. The medicine is transported without any special features.

In clinics, drugs with such a short shelf life are usually not used or stored.

Application of Protargol

It must be remembered that Protargol is used only topically. It can be dropped into the nose, ear, eye, but should not be drunk under any circumstances. Silver is not as harmless as it may seem; it settles on internal organs and can cause harm.

Dosage of Protargol:

The required concentration of the drug is instilled into the ear, eye or nose, 1-2 drops 2-4 times a day.
When treating sinusitis I use a 2% solution. It would seem that the difference is small between 1 and 2%, but there is still a difference. A 2% solution is more effective, but also more dangerous. It is very important to follow the dosage prescribed by your doctor and not exceed it.
For cystitis, wash the bladder with a 2% Protargol solution. This is not a home procedure and you are unlikely to be able to do it yourself. First, you need to insert a catheter into the urinary canal and release the accumulated urine. Then, using a Janet syringe (this is not a simple syringe, but a special, wide one, for washing various cavities, it ensures the sterility of the procedure), the solution is injected until the desire to go to the toilet appears. After this, the syringe and catheter are disconnected and the liquid is released. And so on up to 10 times. This is not the most pleasant, but effective procedure. There should not be any severe pain, but if there is inflammation there may be pain. If you rinse incorrectly, there may be various complications: blood in the urine, pain, urinary fever.
For rhinitis, Protargol is prescribed only in the case of purulent discharge. For a viral infection, this drug will not only not help, but will also worsen the situation by destroying bacteria and thereby allowing viruses to actively multiply.

Protargol is also prescribed to children, but not so often. Before treating rhinitis in children, the nose must be rinsed, cleared of mucus, and then the drug must be instilled into each nostril in the dosage prescribed by the doctor.

Protargol is very popular in the treatment of childhood chronic diseases of the upper respiratory tract.

The effects of silver are difficult to compare with various sprays. It is advisable to use the drug to treat children at least 5 years old. I also use Protargol for prevention, but quite rarely. For example, in maternity hospitals they may use the drug for instillation into the eyes of newborn children. This helps prevent suppuration of the eyelids, which so often appears in babies after birth.

Side effects, contraindications

Possible side effects of using the drug

Protargol is not a harmless remedy, like, for example, Aqua Maris for the nose. Silver can cause a severe allergic reaction, which will manifest itself in the form of skin itching, redness, swelling, burning, and rash. Oddly enough, the drug is much safer for newborns and infants than for adults. And with a single drop into the eyes immediately after birth, the side effects are completely reduced to zero.

If the dosage is violated, dry mouth, dizziness, and headaches may occur.

People who are initially prone to allergies and have many allergic reactions should avoid using silver preparations. Protargol is also prohibited for pregnant women and nursing mothers.

For the treatment of children, only a 1% solution of the drug is used.

More concentrated solutions are excluded. In this case, the entire course of treatment should be supervised by a pediatrician. It is worth remembering that the drug is toxic. It is intended for external use only. For this reason, it should be kept out of the reach of children.

More information about Protargol can be found in the video.

Silver itself is a heavy metal that carries a certain danger. Even when used externally, silver tends to accumulate in tissues and is very difficult to remove.

If the drug gets inside, silver begins to quickly spread throughout the body, settling in the organs, causing a specific disease such as argyrosis. This rather rare disease is accompanied by an irreversible change in the color of the skin. A person literally becomes metal or silver. There is no treatment currently available. The skin will remain this way forever, which brings certain psychological inconvenience to patients. But this is not the main danger. The worst thing is that a large amount of silver in the body can lead to pulmonary edema and death.

Protargol has a strong anti-inflammatory and antiseptic effect. Widely used for inflammatory diseases. How to properly store it at home? After all, the effectiveness and safety of use are closely related to the correct storage of such a “noble” medicine.

Shelf life of Protargol

Protargol is not available in finished form; it is prepared to order at the pharmacy. The drug prepared in the pharmacy can be stored for 30 days before opening, and only 14 days after the first opening of the bottle of medicine. After the expiration date, the use of the drug is strictly prohibited. If there are several days left before the indicated expiration date, then you can still use it, but immediately after that you need to take a new package.

Over time, oxidative reactions occur in the medicinal solution, the active substance is destroyed, its toxicity increases, and a precipitate may form. This results in a significant reduction in efficiency. Therefore, taking expired or unusable medicine is very risky.

How do you know if the medicine can be used?

The expiration date must be checked first. It is indicated on the label. If the bottle has already been opened, it should have the date of opening on it.
Then you need to assess the condition and integrity of the packaging. The bottle is dark glass or transparent, but wrapped in special thick paper. The glass bottle should not have chips or cracks. The label clearly and legibly states the name, concentration, volume of the medicine, its production and expiration dates, and the name of the manufacturer.
Next, you need to check whether the medicinal solution meets the characteristics specified in the instructions. The color of protargol is uniform from dark brown to brown-red. May have slight sediment on the bottom.

The use of an expired or otherwise unsuitable Protargol solution can have serious consequences. The most dangerous are toxic burns, dermatitis and allergic reactions, up to anaphylactic shock with loss of consciousness. Toxic damage to the mucous membrane often leads to severe atrophy and damage to the capillary system in the area of application. This is fraught with bleeding.

Therefore, under no circumstances should you use expired Protargol.

The question arises, why does Protargol have such a short shelf life? The active substance of Protargol is a protein compound of silver. Its molecules are very unstable and quickly undergo oxidation, especially in light. If you keep the bottle warm and in the light for more than an hour, the silver ions will lose stability and precipitate. Therefore, the opened ready-made solution can only be stored for 2 weeks and under appropriate conditions.

Pharmacodynamics

Silver-based product (silver proteinate contains 7.5-8.5% silver). Has an astringent, antiseptic and anti-inflammatory effect. Dissociates to form silver ions, which bind to bacterial DNA and prevent their proliferation on mucous membranes when applied topically. The mechanism of action of silver proteinate is based on the fact that silver ions precipitate proteins and form a protective film on the damaged mucous membrane, which helps reduce the sensitivity of nerve endings and narrow blood vessels (this leads to a decrease in swelling), which in turn inhibits inflammatory reactions. Silver ions also inhibit the proliferation of various bacteria. Active against gram-positive and gram-negative microorganisms: B. cereus, C. albicans, E. coli, P. aeruginosa, S. aureus, A. niger, S. Abony, etc.

Side effects

Possible: mild irritation of the mucous membrane, burning, itching, allergic reactions (urticaria, atopic dermatitis, Quincke's edema, anaphylactic shock).

Silver proteinate is inactivated by alkaloid salts, epinephrine.

Overdose

Symptoms: with the recommended method of use, an overdose is unlikely.

Possible increased side effects. If a large amount of the drug is accidentally swallowed, irritation of the gastrointestinal tract may occur. With prolonged uncontrolled use of the drug, it is theoretically possible for a very rare disease to appear - argyrosis (gray or bluish discoloration of the skin and mucous membranes). If the recommended dosage regimen is followed, the risk of argyrosis is unlikely.

Treatment: in case of severe irritation, burning, itching of the eyes, skin, mucous membranes, rinse with plenty of water for 15 minutes. Treatment is symptomatic.

Impact on the ability to drive vehicles and operate machinery

The drug does not affect the ability to drive vehicles or engage in other potentially hazardous activities that require increased concentration and speed of psychomotor reactions.

General characteristics of the drug

Protargol is pre-ordered at a pharmacy where there is a special laboratory. The pharmacist assigns the buyer a day to pick up the prepared drops and tells them how to store Protargol. The silver solution is never prepared in advance, and there is no point in doing so. After just two weeks, the drug loses its medicinal properties and becomes unsuitable for use.

The mechanism of action of this drug is as follows. Protargol envelops the damaged mucous membrane of the nasal passages and promotes vasoconstriction. This substance has a detrimental effect not only on pathogens, but also on fungi. The effect on viruses is not very pronounced.

This drug has been used to treat runny nose for several decades. This popularity is explained not only by its high efficiency, but also by its very low price.

It is recommended to store Protargol after opening for no more than 2 weeks, although some doctors say that the drug can be used for a month if stored in the cold. But it is worth considering that after 2 weeks of storage the drug gradually loses its medicinal properties.

Protargol is still often prescribed for various purulent processes, although the pharmaceutical industry produces many modern antiseptics.

Expired protargol

If the expiration date of protargol has already expired, it cannot be used categorically. If the course of treatment is not completed, you should order a fresh drug from the pharmacy.

You can tell that a medicine has lost quality by its condition. If a silvery coating has formed on the walls of the container, and the consistency of the solution is no longer homogeneous, it cannot be used. The color or smell of the composition may also change.

Preparations based on silver ions are safe and effective remedies for runny nose and other inflammatory processes of the nasopharynx of infectious origin. Therefore, they have been prescribed to adults and children for many decades.

But so that instead of a positive effect, such treatment does not lead to even greater problems, you should know where and how long you can store protargol after opening and never use expired drugs.

Indications

The main indications for the use of Protargol are the following diseases:

Otitis media. This disease is most often treated with antibiotics, but Protorgol can complement therapy and quickly eliminate the inflammatory process. This drug is often prescribed for purulent otitis, it prevents the infection from spreading further.
Conjunctivitis. This infectious disease affects the mucous membrane of the eyes. The organs of vision become watery, burning and pain appear in them. When the condition is neglected, the eyes become very sour and pus appears. Ophthalmologists prescribe Protargol to reduce inflammation and wash the mucous membrane of pus.
Sinusitis. This pathology most often occurs with the release of pus from the nasal passages. Protargol effectively eliminates bacteria and fungi, which speeds up recovery.
Cystitis. The drug is also used in urological practice to wash the ureter.

For the drug to be effective, the shelf life after first opening must be 2 weeks.

The silver solution should be stored out of the reach of children, which will prevent severe poisoning.

Rules for storing the drug

Protorgol cannot be diluted at home, and it needs to be stored under proper conditions for 2 weeks, although some experts say that the medicine can be used for up to a month. Buying dry powder from a pharmacy chain and trying to dilute it is pointless if you do not have pharmaceutical education and special measuring instruments. When diluting, it is very important to correctly determine the concentration, since a weak solution will not have an effect, and a strong solution can lead to burns of the mucous membrane.

There is also no need to self-medicate or order medicine without a doctor’s prescription. The concentration of the silver solution may differ in each individual case. Most pharmacies do not dispense this medicine without a doctor's prescription. Preparing the composition does not take much time; in just half an hour you can pick up your order from the pharmacist.

It is not for nothing that Protorgol is not produced in finished form. This medicine is unstable and decomposes very quickly. Therefore, it is not only important to prepare it correctly, but also to observe certain storage conditions.

Use and store Protargol drops at home in compliance with certain rules:

Drops are stored in a cool place protected from light. The medicinal product must be stored in its original packaging. Pharmacists pour the medicine into bottles made of thick, dark glass. The bottle should not be left in the light; after each use, it is hidden on the bottom shelf of the refrigerator.
If you have pharmaceutical experience and the solution is prepared at home, then use a thick-walled glass container and a glass spoon to dilute the silver powder. Water is taken for injection or distilled. The prepared solution is poured into dark glass bottles with a tightly sealed lid and stored in the refrigerator. To maintain the shelf life, a label is attached to the bottle stating the date of dilution, time and concentration of the active substance.
Dry powder purchased at a pharmacy should also be stored in a cool and dark place, avoiding moisture. If the powder accidentally gets wet, it is thrown away, regardless of the period that has passed since the purchase.
If the medicine has been stored in a warm place or in direct sunlight for several hours, it should also be thrown away. In this case, the silver first precipitates and then dissolves again; such a medicine will not have an effect.

Pharmacists tell the buyer the expiration date of Protargol. Typically, silver solution is recommended to be stored for no more than 30 days. In this case, Protorgol, prepared in a pharmacy, is stored for 2 weeks. And the drug Sialor, which is available in the form of a kit for preparing drops, can be stored longer. The instructions for use of Sialor allow storage of the finished solution for a month.

It is quite possible to determine that a solution is no longer suitable by its appearance. A silvery coating appears on the walls of the bottle, and the silver solution itself becomes heterogeneous.

Before each use, the bottle with Protargol is warmed in the palms of your hands for several minutes and then shaken.

Additional factors affecting product quality

Before starting medication treatment, you must familiarize yourself with the rules for storing the medication.

When using a popular and effective remedy, you need to remember the following facts:

The drug is released in dark glass containers. If the pharmacist offers the medicine in a different package, it is better to refuse the purchase and purchase the medicine at another pharmacy.
Protargol, presented on the medical market in the form of a powdery substance, is stored no longer than the liquid form of the drug. The powder must be placed in a dry and cool room. If the contents of the bag become wet, it is discarded.
If you prepare the liquid composition yourself, you must carefully study all the details of the process. You should prepare glassware in advance (boil a plate and spoon). Water is heated in a porcelain teapot.
Sialor is packaged in bottles made of dark material with well-closing lids. The products are placed on the bottom shelf of the refrigerator. Before use, the contents of the bottle should be shaken slightly.

You should not self-medicate, because Protargol can cause severe poisoning. An inaccurate dose of the drug taken by the patient will cause an increase in the symptoms of the pathological process, which will lead to dangerous consequences.
