Is the medicine expiration date up to this month inclusive or not: how to find out or determine if the tablets are unpackaged and the date is not indicated, how can you tell if they are spoiled? Legal.Standard

After opening the bottle, the saline solution is stored for 12 hours in the refrigerator. A number of conditions must be met: draw with a syringe, do not damage the stopper and protective cap, place in a cardboard box. All these rules are especially important when using a nebulizer to treat pneumonia, bronchiectasis, and damage to the lower bronchi. In case of viral infections of the nasopharynx and the possibility of spraying large particles, allergies, the shelf life can be increased to 1.5-2 days.

A more economical way for inhalation is to purchase ampoules with saline solution; if this is not possible, then syringes can be filled with saline solution to increase suitability. For most factory-made drugs, before opening, the shelf life is 2 years for vials and 3-5 years for ampoule forms and plastic nebulas (mini containers).

How long does saline solution last after opening?

How long the saline solution will be stored without losing its properties after the bottle is opened will depend on the purpose of use:

injection into a vein - storage is not allowed, since absolute sterility is immediately lost;
dilution of medications for intramuscular injections - if absolutely necessary, stored for 12 hours in the refrigerator, but if the opening rules are followed;
inhalation in a nebulizer - good for 2 days if opened and stored correctly;
inhalation in a steam inhaler - can be used until completely used up if stored in the refrigerator, becomes unusable when external signs appear - turbidity, sediment, flakes, as well as the expiration date indicated on the label;
washing, rinsing, diluting medications for external use - good before the expiration date.

You can store an open saline solution in a bottle for a long time only if you follow the rules:

Only the protective cover is open;
the rubber stopper and the surrounding foil are not damaged;
take a needle from the bottle, which must then be covered with a sterile cloth moistened with alcohol;
the solution is placed in a cardboard box and placed in the refrigerator.

Since the drug is cheap, this option is used very rarely. Typically, the question of how long an open saline solution is valid arises when performing inhalations, since 1 ml for a child and up to 3 ml for an adult are enough for one procedure. Even when inhaling a pure solution, the nebulizer is filled with a maximum of 7 ml.

In this case, a bottle of 200-400 ml is consumed slowly. Therefore, a more economical option would be to purchase ampoules of the drug or a smaller volume.

It is also important to know that the shelf life may not be limited if:

the device has a function for adjusting the particle size;
the mode of spraying droplets from 5 microns is selected;
treatment is necessary for the nasopharynx (runny nose, sore throat, sore throat).

Large parts of the aerosol in this case are predominantly deposited in the upper respiratory tract, so complete sterility of the solution is not required.

From it you will learn about how to use saline solution for inhalation with a nebulizer, features of use in pregnant women, and how to replace saline solution for inhalation. And here is more information about why aminocaproic acid is prescribed for inhalation for children.

Is it possible to store homemade saline solution open?

Homemade saline solution can be stored open for up to a day, but it should be used exclusively for salt inhalations in a steam (heat-moisture device), as well as washing and rinsing. It is prepared by diluting table salt in boiled water. Even if you boil it again and process the dishes, it is impossible to achieve complete sterility at home.

Administration through a nebulizer is permitted only for pharmaceutical drugs. In this case, a liquid that is free of microbes (they die only during autoclaving) and impurities (special filtration is required) must enter the bronchial tract.

Factory-made preparations are prepared not with ordinary, but with distilled water. This is especially important when diluting medications, since foreign salts can interact with the medication and interfere with its activity.

How long does open saline solution for inhalation in ampoules or bottles last?

After opening, saline solution for inhalation is stored unopened for 12 hours in a bottle, and in an ampoule for 6 hours. The reduction in time in the latter case is due to the fact that after breaking off the tip, the hole must be closed with a cotton swab, which, by definition, will not be completely sterile. Therefore, a glass or plastic container (nebula) can be successfully divided into no more than 2 parts.

If there is a need to store the drug for a long time, you can use sterile syringes. For example, each procedure requires 2 ml of the drug. Then this amount is drawn into a syringe of appropriate capacity or 5 ml and stored in the refrigerator, closing the needle with a cap. In this form, the inhalation drug can be used for 5-7 days, which is enough for a standard course of treatment.

Saline solution in disposable containers

It is convenient to warm the saline solution in syringes and ampoules to body temperature. To do this, they are immersed in hot water at 38 degrees for 3-5 minutes. This preliminary preparation helps to avoid reflex bronchospasm. It is strictly forbidden to pour the drug into the nebulizer directly from the refrigerator or place it on an open fire or in a microwave oven.

Shelf life of saline solution

Saline solution, or 0.9% sodium chloride, in glass bottles (50, 100, 200, 250, 400, 500, 800 ml, 1 liter) most often has a shelf life of 2 years. It is produced by a number of domestic and foreign enterprises according to various technical regulations. Therefore, the same release form may have a longer period of use (for example, 3 years), and ampoules are stored until opening for 3 to 5 years.

The drug prepared in a pharmacy, as well as in plastic containers, is less suitable for use. When purchasing, it is important to carefully study the production date and expiration date stamp. If the labeling is unclear or there is no series on the bottle, you must request documentation for the drug (certificate of conformity with a seal).

Basic Rules

Naturally, to know whether a perfume has an expiration date, it is better to ask the store directly. The product itself must be sold in glass, not plastic, otherwise it will deteriorate very quickly. Having chosen the option you like, you need to find where the information about the storage period is located. Many leading brands indicate barcodes and batch codes next to each other. On perfumes produced in the Russian Federation, two dates are usually simply indicated. In the case of a famous foreign brand, you can use a ready-made formula for decoding.

If the brand is little-known, you should ask the sales consultant to demonstrate a table with batch codes. This information should also be posted on the manufacturer’s official website. If there is no sign, it is convenient to use an online calculator or mobile application to read it. When purchasing vintage perfumes, there is no point in paying attention to this parameter. To check whether a perfume is suitable for use, it is worth inspecting the perfume. If the liquid has a strange color, there is sediment at the bottom of the container, or there is a musty smell, there is no need to buy it.

Be sure to follow storage rules immediately after purchase. Otherwise, the aroma will deteriorate before the end of the date specified by the manufacturer. Even newly released eau de toilette will quickly dry out and lose some of its notes if not handled correctly.

Why does sodium chloride have a short shelf life after opening?

After opening, 0.9% sodium chloride has a shelf life of no more than 12 hours, which is due to the loss of its sterility. Even if the opening rules are followed, the bottle or ampoule will no longer be completely sealed, since it is in contact with air. Therefore, microbes will penetrate through a small hole.

Saline solution in ampoules

The sterility of the solution is considered very important in the treatment of the lower respiratory tract, bronchiectasis, pneumonia, and alveolitis. In case of colds and allergic pathologies, the normal state of immunity, the shelf life of the drug in the refrigerator can be slightly increased - up to 1.5-2 days.

Tips for choosing

To choose a quality product, you need to pay attention to the following points:

Naturalness. A powder intended for preparing an instant drink cannot be natural. Real cocoa is brewed on the stove like coffee.
The presence of the mark “non-alkalized”. This indicates that the powder has not been treated with chemical components and has retained a maximum of useful substances.
Fat content indicator. In a quality product, the proportion of fat cannot be less than 15%.
Structure and color of the powder. There should be no lumps or large grains in it. The color is completely uniform. Gray tint is not allowed.

Note to the hostess
To make sure the quality of the cocoa powder, you need to take a small pinch of the substance with your fingers and rub it. Then shake it off and inspect your hands. If a greasy brown coating with a characteristic aroma remains on your fingers, then you bought excellent cocoa.

A natural product will always leave sediment after cooking.

Does the shelf life increase if complex inhalations

Complex inhalations with saline solution are prescribed more often than with the pure drug, but its shelf life does not change. It is equally important to use a sterile medication as a solvent. Therefore, it is best in such cases to buy ampoules or plastic containers and open a new one each time . Since 10 pieces cost about 50 rubles, such costs for inhalation therapy will not be too high.

Signs of damage

If storage conditions are not met or the expiration date has expired, it is advisable to periodically check the product. Signs of damage will be :

the appearance of a musty smell ;
any change in original color ;
identification of insects that have “settled” in the product;
the presence of mold , which happens when you constantly take the powder with a wet spoon;
resulting lumpiness .

In any of these cases, cocoa has one path - to the trash bin.

Is it possible to use expired saline solution?

For any method of treatment, it is undesirable to use expired saline solution. When used externally (rinsing, washing), it is considered conditionally suitable for one month if:

the bottle was closed and placed in a cardboard package;
the sun's rays did not fall on it;
The storage temperature did not rise above 25 degrees.

If saline solution is used after opening, then it cannot be used after the expiration date.

Features of preparing saline solution at home

Self-preparation of saline solution follows the instructions:

filter and boil the water;
dissolve a small heaped teaspoon of table salt in 1 liter (if the grind is fine, then no heap);
wait for complete dissolution, precipitation of possible impurities and carefully pour the solution into a clean dark glass jar or wrap it in thick paper.

This solution is only suitable for use in a heat-moisture inhaler. A salt procedure is carried out with it, then it is heated to 55-60 degrees and 500 ml is poured into the device.

It is possible to add a coffee spoon of soda to the homemade saline solution for 1 procedure to enhance the softening, moisturizing and anti-edematous effect. This composition is also used for gargling and nasal rinsing. The nebulizer is not filled with homemade saline solution.
