Proper storage of medications is a critical aspect of their safe use, and the centrally acting muscle relaxant called Mydocalm is no exception. Many patients, when faced with the prescription of this drug in ampoules for the first time, wonder where exactly and at what temperature it is necessary to contain the injection solution so that it does not lose its pharmacological properties. Errors in observing the temperature regime can lead to changes in the chemical composition of the active substance, which will make the treatment ineffective or even dangerous to health.
In this article we will analyze in detail the storage conditions tolisopane hydrochloride, which is the main active component of the drug, and also consider the nuances associated with freezing, transportation and expiration date after opening the package. Compliance with the rules will allow you to be confident in the quality of the administered medication and avoid unpleasant situations during the course of therapy. It is important to understand that the requirements for the liquid form of release (solution in ampoules) may differ from the requirements for the tablet form.
Before moving on to specific numbers and temperature ranges, it is worth noting that pharmaceuticals belong to the category of goods that require special attention to environmental conditions. Light, humidity and sudden changes in temperature are factors that can negatively affect the stability of the molecular structure of a drug. Therefore, the question of whether it is necessary to put Mydocalm in the refrigerator or whether it is enough to leave it in the closet requires a clear and reasoned answer based on the manufacturer’s official instructions.
Official requirements for storage instructions
The main document regulating the conditions for keeping the drug is official instructions for medical useapproved by the manufacturer and regulatory authorities. According to the data indicated in the insert for the Mydocalm drug in the form of an injection solution, the optimal temperature range is considered to be from 8 to 15 degrees Celsius. This means that standard room temperature, which often fluctuates between 20-25 degrees, already exceeds the recommended standards for long-term storage.
In this regard, the answer to the question whether Mydocalm needs to be stored in the refrigerator is affirmative. Refrigerator compartment is the only place in living conditions, which can provide a stable temperature within 8-15°C all year round, regardless of the season and the operation of heating systems. Storing the drug on a shelf in the bathroom or on the kitchen table can lead to its spoilage, especially in the summer or during the heating season, when the room temperature exceeds permissible values.
It is also important to consider protection from light. Ampoules with the solution should be located in a place protected from direct sunlight and sources of high-intensity artificial lighting. Ultraviolet radiation can provoke photochemical reactions that change the transparency and color of the solution. Therefore, even inside the refrigerator, it is recommended to keep the drug in its original cardboard packaging, which serves as an excellent light-protective barrier.
⚠️ Attention: Never store Mydocalm ampoules on the refrigerator door. Due to frequent opening of the door, the temperature in this compartment fluctuates greatly, which can lead to failure of the drug. Place the packaging on the middle shelf close to the back wall.
Are freezing and low temperatures acceptable?
A frequent mistake of patients is the belief that if storage at 8-15 degrees is useful, then freezing will make the drug even more “fresh” or preserve it forever. This is a dangerous misconception. Freezing injection solution is strictly prohibited by the manufacturer. At temperatures below 0 degrees Celsius, crystallization occurs not only of water, but also of the excipients included in the solution, which can irreversibly damage the structure of the active substance.
If you accidentally left Mydocalm in the cold (for example, during transportation in winter) or placed it in the freezer, use such a drug impossible. Even after thawing and visually returning to a liquid state, microscopic crystals can form in the solution, which, when injected into a muscle or vein, will cause severe pain, inflammation or even embolism. In addition, the chemical bond of tolisopane molecules during freezing can be destroyed.
Particular attention should be paid to the appearance of the solution before use. If you notice that the liquid in the ampoule has become cloudy, changed color, or a sediment (flakes, crystals) has appeared in it, this is a direct indication of a violation of storage conditions. Transparency and colorlessness —mandatory characteristics of a high-quality Mydocalm solution. Any deviations from this norm are a signal to dispose of the drug.
What happens to the chemical composition when it freezes?
When freezing, the aqueous base of the solution expands, creating pressure inside the ampoule, which can lead to microcracks in the glass. In addition, freezing of water leads to an increase in the concentration of salts and active substances in the remaining liquid, which changes the pH balance and can cause precipitation that will not dissolve back when heated.
Shelf life and conditions after opening the package
The shelf life of the Mydocalm drug in a sealed package is usually 3 years from the date of production, subject to the temperature conditions 8-15°C. The date of manufacture and the end date of use can always be found on the end of the cardboard box or directly on ampoule. After this period, it is prohibited to use the medicine, since the manufacturer can no longer guarantee its safety and effectiveness.
The issue of storing an open ampoule deserves special attention. Mydocalm injection solution does not contain preservatives in quantities sufficient for long-term storage after a leak. Opened ampoule must be used immediately. It is strictly forbidden to leave a started ampoule “for later,” even in the refrigerator. Microorganisms from the air can enter the sterile solution, and oxidation with oxygen will change the properties of the drug.
If there is some liquid left in the ampoule after the injection, it should be discarded. Storing an open ampoule even for several hours increases the risk of developing infectious complications upon repeated administration. Sterility is a fundamental principle of injection therapy, the violation of which is unacceptable.

Rules for transporting and transporting the drug
Transportation of Mydocalm from the pharmacy home or to a destination (for example, on vacation or a business trip) requires compliance with the same temperature rules as stationary storage. If you buy the drug in winter, when the temperature outside drops below zero, you need to take precautions. Ampoules should not be carried in open hands or in a thin plastic bag. thermal insulation. Ampoules should not be carried in open hands or in a thin plastic bag.
For transportation, it is recommended to use thermal bags or thermal containers. In winter, ampoules should be kept closer to the body (in the inner pocket of the jacket) so that the body’s heat prevents the solution from freezing. In summer, on the contrary, it is important to prevent overheating above 15 degrees, so the use of refrigerants in a thermal bag will be justified, but direct contact of ampoules with ice or gel cold accumulators is unacceptable - you need to lay a layer of fabric.
When traveling by car in hot weather, you should not leave the package with the medicine in the car in direct sunlight. The temperature inside the car can quickly rise to 40-50 degrees, which will lead to spoilage pharmacological agent. The best place in the car is the glove compartment (if it does not heat up) or a cooler bag.
| Condition | Acceptable range/Action | Risk of violation |
|---|---|---|
| Storage temperature | 8°C – 15°C | Deterioration of the active substance |
| Freezing | Prohibited (below 0°C) | Sedimentation, loss of properties |
| Light | Protection from direct rays | Photochemical reaction |
| Open ampoule | Use immediately | Infection, oxidation |
Compatibility and interaction during storage
Although Mydocalm is often prescribed in combination with other drugs (for example, B vitamins, non-steroidal anti-inflammatory drugs), storing them in the same container or in close proximity without packaging is not recommended. Different medications may have different requirements for environmental conditions. For example, some drugs require storage at temperatures up to 25°C, which is higher than recommended for Mydocalm.
In addition, there is a risk of cross-contamination or confusion if ampoules of different drugs are lying loose. Always store Mydocalm in its original packaging. This not only protects from light, but also preserves information about the batch and expiration date. If you store medications in a special organizer for medications, make sure that it is also in the refrigerator if the storage mode of the main drug requires it.
Particular attention should be paid to the vicinity of food. Medicines should not be stored near products, especially those that have a strong odor or can become a source of bacteria (meat, fish, open containers). Glass ampoules are sealed, but additional insulation in the form of a cardboard box or plastic container will not be an unnecessary precaution.
⚠️ Attention: If you are using a “No Frost” type refrigerator, make sure that the flow of cold air does not blow directly onto the package with ampoules. Local hypothermia can lead to damage to the glass or a change in the properties of the solution.
Common mistakes of patients and myths about storage
One of the most common mistakes is storing the drug in a “first aid kit” in the kitchen or bathroom at room temperature. Patients often argue that “nothing has happened before” or “the instructions say up to 15 degrees, but ours is 20.” However, modern pharmaceutical standards require strict adherence to the range. Exceeding the temperature by even a few degrees for a long time (months) accelerates the degradation processes of the active substance.
Another myth says that if the solution has warmed up a little, it can be “saved” by putting it in the refrigerator. Unfortunately, decomposition processes triggered by high temperatures are often irreversible. Degradation of molecules does not occur according to the “on-off” principle. Therefore, if you know that the drug was kept warm for a long time (for example, lying in a car in the summer), its use is risky.
Also, patients often ignore the need to warm the ampoule before administration. Although this does not directly relate to storage, it is related to the temperature of the drug. Injecting a cold solution from a refrigerator into a muscle causes severe pain and can lead to the formation of infiltrates (“bumps”). Before the injection, the ampoule must be warmed in your hand or held under running warm water until it reaches body temperature.
How to properly prepare the drug for injection
Directly Before administering the drug, you must remove the ampoule from the refrigerator. Since storage is carried out at a temperature of 8-15°C, and administration requires a temperature close to body temperature (36.6°C), an adaptation step is necessary. A sharp injection of a cold solution into muscle tissue causes vasospasm and increases pain, which is especially undesirable when treating muscle spasms, for which it is prescribed Mydocalm.
The warming process is simple: just hold the sealed ampoule in your palm for 2-3 minutes or roll it between fingers. Do not use hot water, radiators or microwave ovens for this. Local overheating may destroy the active substance faster than prolonged storage at the wrong temperature. The goal is only to equalize the temperature of the liquid with the body temperature.
After warming, the ampoule is wiped with an alcohol wipe at the site of the break, broken and the solution is drawn into a syringe. The injection should be done deep into the muscle (usually the gluteal) or intravenously (only in a medical facility and slowly), following the doctor’s instructions. Compliance with the administration technique is as important as the correct storage of the drug up to this point.
Can Mydocalm tablets be stored in the refrigerator?
No, the tablet form of Mydocalm (Mydocalm 50 mg and 150 mg) is stored at temperatures up to 25°C in a dry place, protected from light. Placing the tablets in the refrigerator is not necessary and even undesirable, since high humidity in the refrigerator compartment can lead to the coating or the substance itself becoming soggy. The tablets are stored in a home medicine cabinet.
What to do if the solution in the ampoule turns yellowish?
According to the instructions, the Mydocalm solution should be colorless. A slight yellowish color may indicate the onset of oxidative processes or a violation of storage conditions (light, temperature). The use of such a drug is not recommended, since its safety and effectiveness are not guaranteed. It is better to purchase a new package.
How long can you keep Mydocalm out of the refrigerator?
A short-term stay of the drug at room temperature (for example, during transportation from a pharmacy or for several hours before an injection) is not critical. However, systematic storage outside the refrigerator (more than 24 hours) at temperatures above 15°C is not recommended by the manufacturer and may reduce the effectiveness of the course of treatment.
Is it possible to freeze Mydocalm to extend the shelf life?
Absolutely not. Freezing the injection solution destroys its structure. After thawing, crystals that are invisible to the eye may form in the solution, which, when injected into the muscle, will cause severe inflammation, pain and the risk of embolism. Frozen Mydocalm must be disposed of.
Is it necessary to shake the ampoule before use?
Mydocalm solution does not require shaking, since it is a ready-made liquid form (not a lyophilisate that needs to be dissolved). If you see a sediment that does not disappear, the drug should not be used. In its normal state, the solution should be absolutely transparent and homogeneous without any inclusions.
