Non-steroidal anti-inflammatory drugs, which include Artrosan, require strict adherence to temperature conditions to preserve their chemical structure. Many patients mistakenly believe that since the medicine is intended to be administered into the body, it must be kept exclusively in the cold, like insulin or some antibiotics. However, violation of temperature conditions can lead not only to a decrease in the effectiveness of the active substance, but also to the formation of a precipitate, making the injection dangerous.
The main active component of this drug is meloxicam, which in ampoule form is stable at room temperature, but is critically susceptible to freezing. Improper storage of injections can lead to crystallization of the solution, which, when administered intramuscularly, will cause severe pain, tissue inflammation, or even an abscess. Therefore, the question of where exactly to keep the packaging in the refrigerator or outside it is not just a formality, but a safety requirement.
In this article we will analyze in detail the manufacturer's requirements, features of temperature conditions and answer the question of whether it is necessary to place Artrosan in the refrigerator at all. You will learn how to distinguish a spoiled drug by external signs and what to do if the ampoule is accidentally exposed to low temperatures.
Manufacturer's temperature requirements
Instructions for medical use of the drug Artrosan (meloxicam) contains clear instructions regarding storage conditions medicine. According to official data, the optimal storage temperature is considered to be from +5 to +25 degrees Celsius. This means that the drug belongs to the group of products that do not require mandatory refrigeration, but also do not tolerate overheating.
It is critically important to understand the difference between “refrigerated storage” and “storage at cool room temperature.” If the instructions do not indicate the word “freezing” or the range of 2-8 degrees, then placing the drug on the refrigerator shelf, where the temperature often drops below +4 degrees, is a violation of the regime. Freezing the solution in ampoules is unacceptable, since when the liquid expands, the glass may crack, and the drug itself may lose its properties.
⚠️ Attention: If you accidentally put the ampoules in the freezer or on the shelf with the lowest temperature where ice has formed, using such a drug is strictly prohibited. Ice crystals destroy the molecular structure of meloxicam.
The temperature regime must be constant. Sudden changes, for example, when the packaging is either left in the sun or hidden in the cold, are also harmful to the stability of the solution. The ideal place in the apartment is considered to be a closed cabinet away from heating devices and direct sunlight.
Does Artrosan need to be stored in the refrigerator
The question of whether it is necessary to put Artrosan in the refrigerator arises for many patients, especially in the summer, when the room temperature can exceed 25 degrees. The answer depends on the current conditions in your room. If the air temperature does not rise above +25°C, then additional cooling is not required and is not even advisable due to the risk of accidental freezing.
However, if the room is hot, using a refrigerator becomes a necessity, but requires compliance with strict rules. You can’t just put ampoules on a shelf next to food. It is necessary to choose an area with the most stable temperature, usually the refrigerator door or the top shelves, but away from the back wall where the freezer operates.
There is a common misconception that “the colder it is, the better the medicine is preserved.” For aqueous solutions ampoules this is not the case. If the temperature is too low, the process of separation of components or precipitation may begin, which is not always noticeable to the eye immediately after removal from the cold.
Rules for placing ampoules in the refrigerator compartment
If you decide to place the drug in the refrigerator due to high ambient temperatures, it is important to organize it correctly storage. Ampoules must be protected from direct contact with the cold air of the freezer compartment and from moisture. It is best to leave them in the original cardboard packaging, which serves as an additional thermal insulating barrier.
The packaging should be placed so that it does not touch the walls of the refrigerator, especially the back panel, where the temperature can drop to 0 degrees or below. A special container for medicines in the door is ideal if the temperature is above zero, or a separate shelf where the risk of freezing is minimal.
It is also worth considering the proximity to the products. Medicines should not be stored near open food, especially meat or fish, to avoid microbiological contamination (outer packaging). Although the ampoules are sealed, storage hygiene is important.
☑️ Rules for storing in the refrigerator
Shelf life and conditions after opening the package
The shelf life Artrosanaindicated on the packaging is usually 24 or 36 months (2-3 years) from the date of production, but this is relevant only for unopened original packaging and subject to temperature conditions. After you have opened the cardboard box and taken out the blister, the general storage rules do not change, but there is a risk of mechanical damage to the ampoules.
It is important to note that the ampoules are intended for single use. Opened ampoule cannot be stored. If there is any solution left in the syringe after the injection, it must be discarded. It is impossible to store an open ampoule even in the refrigerator, since microorganisms can get into the solution, and the sterility of the drug will be impaired.
Periodically check the expiration date, especially if the drug is stored “just in case.” Expired meloxicam can change its pH balance, which will make the injection painful or toxic to the body.
| Parameter | Normal | Critical deviation |
|---|---|---|
| Storage temperature | from +5 to +25 °C | Below 0 °C or above +30 °C |
| Shelf life | 2 years (24 months) | Use after the date on the package |
| External appearance | Transparent yellowish solution | Presence of flakes, sediment, turbidity |
| Packaging | Sealed, factory-made | Violation of integrity blister |
How to understand that the drug is spoiled
Visual inspection is the first and most accessible way to check the quality of the drug before use. The solution Artrosana in ampoules should be transparent and have a yellowish or greenish-yellow tint. Any changes in color, the appearance of turbidity or suspension indicate a violation of the chemical composition.
If you take the ampoule out of the refrigerator and see that crystals have appeared inside, which do not disappear when warmed in your hand to room temperature, you cannot use this drug. This is a sign that an irreversible change in the structure of the substance has occurred or precipitation of auxiliary components has occurred.
What to do if the ampoule breaks in the refrigerator?
If the ampoule breaks, you must immediately remove the fragments and wipe the shelf with a damp cloth, and then with a dry one. Meloxicam in powder or solution form should not come into contact with food. Wash your hands thoroughly with soap after cleaning.
Also pay attention to the integrity of the ampoule itself. Microcracks, which sometimes occur due to improper storage or transportation, may not be immediately visible, but lead to loss of sterility. If chips or sealing defects are visible on the neck of the ampoule, it is better to throw away such a unit.
Transportation and storage on the road
Often there is a need to take the drug with you on a trip. If you travel in the summer, when the temperature in the car can reach high values, the issue of storage Artrosana becomes relevant. Leaving the packaging in the car in direct sunlight is strictly prohibited - the temperature inside can rise to +50°C or higher, which will destroy the drug.
For transportation, use a thermal bag or thermal container. However, do not put regular ice in such a bag in the immediate vicinity of the ampoules, so as not to freeze them. Use special refrigerants or simply try to keep the drug in the shade and cool.
When flying by airline, it is better to take ampoules in hand luggage, since in the luggage compartment the temperature may drop below the permissible minimum, and the drug will freeze. The packaging should be presented at the inspection as a medicine.
⚠️ Attention: In winter, when transporting outside or in an unheated trunk, there is a risk hypothermia of the drug. Try to keep the packaging in the inside pocket of your clothes or in the bag that you take with you to the cabin of the vehicle.
Frequently asked questions (FAQ)
Is it possible to store Artrosan in the freezer so that it definitely does not spoil?
No, this absolutely cannot be done. Freezing the solution in ampoules leads to a change in its physicochemical properties, possible cracking of the glass and the formation of crystals, which, when administered, will cause severe pain and tissue damage.
What should I do if I accidentally left Artrosan injections in the sun?
If the ampoules were exposed to direct sunlight for a long time (more 1-2 hours) and warmed up, it’s better not to risk it. High temperature may have accelerated the degradation of meloxicam. Visually this may not be noticeable, but the effectiveness of the drug will decrease.
Is it necessary to warm the ampoule in your hand before the injection if it was in the refrigerator?
Yes, before administration, the ampoule with a cold solution must be warmed in your hand to body temperature. Injecting a cold solution into a muscle causes vasospasm, increases pain and slows down the absorption of the drug.
How long can an opened ampoule be stored?
An opened ampoule cannot be stored at all. The drug is intended for single administration. The remaining solution must be disposed of immediately after the procedure, since sterility is compromised.
