The drug Longidaza is a popular enzyme agent widely used in gynecology, urology and surgery to resolve scars, adhesions and reduce inflammatory processes. Since the active substance is a protein molecule, it is extremely sensitive to external influences, and violation of the maintenance conditions can lead to a complete loss of the therapeutic effect.
Many patients are faced with a dilemma: is normal room temperature enough or is it necessary to use a refrigeration chamber? Temperature conditions is a critical factor, determining the stability of the chemical structure of suppositories. In this article, we will look in detail at how to ensure the safety of the medicine and avoid common mistakes.
Improper storage can turn an expensive course of treatment into a waste of time and money. Below are detailed instructions based on the official data of the manufacturer and the physicochemical properties of the drug.
Optimal temperature conditions for suppositories
The main requirement for the conditions of keeping the drug Longidaza is compliance with a strict temperature range. According to the instructions, the optimal mode is considered to be from +2 to +15 degrees Celsius. This means that storage at room temperature (usually about +20...+25°C) is allowed, but only for a limited time, not exceeding 2-3 months.
To ensure maximum safety of the active substance throughout the shelf life, which is 24 months from the date of issue, it is recommended to place the packaging in the refrigerator. At temperatures below +10 degrees Celsius, protein degradation processes slow down, which guarantees stability of the formula. If you plan to use the drug for a long time, the refrigerator is the only right solution.
It is important to consider that sudden temperature changes negatively affect the structure of the suppository. Frequently removing the package from the cold and returning it back can lead to moisture condensation inside the blister, which is unacceptable for hygroscopic substances.
⚠️ Attention: Do not store the drug on the refrigerator door. Due to the constant opening of the door, the greatest temperature fluctuations occur there, which can disrupt the integrity of the fatty base of the candles.
Is it possible freeze the drug
The question of the possibility of freezing often arises among patients who are afraid of damage to the medicine due to power outages or during transportation in the winter. The answer is clear: freeze candles Longidaza strictly prohibited. When the water contained in the suppository base freezes, protein compounds undergo irreversible structural changes known as denaturation.After thawing, the drug will lose its enzymatic properties and become useless. In addition, ice crystals can disrupt the homogeneity of the fat base, making insertion of the suppository painful or difficult. If you notice that candles were accidentally left in the cold or in the freezer, you should not use them.
Storage should also be avoided near the highly cooling elements of the refrigerator, where the temperature can drop below zero. Control the position of the package so that it does not touch the back wall of the chamber, where the evaporator is usually located.
What happens to the protein when frozen?
When freezing, water molecules expand and form crystals that break the peptide bonds in the protein structure of the enzyme. After thawing, the protein does not restore its original shape and ceases to work as a catalyst for biochemical reactions.
Protection from light and humidity
In addition to temperature, critical factors for maintaining the effectiveness of are light and humidity. It is no coincidence that the packaging Longidase is made of opaque materials: ultraviolet and even bright artificial lighting can trigger photochemical reactions of destruction of the active substance.
Moisture is the second enemy of the drug. Suppositories have the ability to absorb moisture from the air, which can lead to a change in their consistency and accelerated spoilage. That is why the candles should be removed from the individual cell of the blister immediately before use.
The drug should be stored in the original cardboard box, even if you keep it in the refrigerator. The box serves as an additional barrier from light and mechanical damage. You should not transfer candles to other containers or bags, this increases the risk of damage.
Transportation and movement
If you need to transport the drug, for example, buy it at a pharmacy and deliver it home in hot weather, you should follow certain rules. A short-term increase in temperature up to +25°C is acceptable, but direct sunlight during transportation is unacceptable. It is recommended to use a thermal bag or at least an opaque bag.
When moving, try not to shake the package or subject it to mechanical shock. Suppositories have a soft base, which can become deformed when impacted, making their subsequent administration difficult. If you are transporting the drug in the cold in winter, hide it in the inside pocket of your clothes so that body heat prevents freezing.
After returning home, immediately place the package in the refrigerator. Do not leave the medicine “for later” on the table or windowsill. Compliance transportation conditions is as important as proper stationary storage.
⚠️ Attention: If the packaging was opened or damaged during transportation, and the candles were in contact with the external environment for more than 1 hour at high temperatures, their use is not recommended.
Shelf life and signs of spoilage
The shelf life of the drug is 2 years from the production date indicated on the package. However, these terms are only relevant if all storage rules are followed. If the temperature regime is violated, the actual lifespan of the drug may be significantly shorter.
Before each use, visually inspect the candle. It should be uniform, smooth, without cracks or foreign inclusions. The base color is usually white or yellowish. If you notice a change in color, the appearance of an unpleasant odor or a change in consistency (for example, the candle has become too soft or, conversely, crumbly), these are signs of spoilage.
Using an expired or spoiled drug will not only not be beneficial, but can also cause allergic reactions or local irritation of the mucous membranes. Saving on health in this case is unacceptable.

☑️ Check before use
Storage features of different release forms
It is worth noting that Longidaza is produced not only in the form of suppositories, but also in the form of a lyophilisate (powder) for the preparation of a solution for injection. The storage rules for the powder are similar: dark place and temperature up to +15°C. However, after dilution, the solution must be used immediately; it cannot be stored.
For suppositories, the integrity of the blister packaging is also important. If the foil film over the cell is damaged, the access of air and moisture to the candle is open, which leads to oxidation of the fat base. Such candles cannot be used, even if the expiration date has not expired.
At home, it is best to allocate a separate shelf or container in the refrigerator for medications, away from food. This will eliminate accidental contamination and help maintain hygiene.
Frequently asked questions (FAQ)
What to do if I accidentally left candles on room temperature for a week?
If the room temperature did not exceed +25°C, the drug most likely retained its properties. However, for further storage it is better to place it in the refrigerator. If it was hotter (+30°C and above) or the candles were in the sun, the effectiveness could decrease, and it is better to consult a doctor about replacing the drug.
Is it possible to store Longidaza along with food in the refrigerator?
Theoretically, it is possible if the packaging is sealed and in a box. However, hygienic standards recommend storing medicines separately from food to avoid cross-contamination and accidental consumption by children.
Is it necessary to warm the suppository before insertion if it is refrigerated?
Yes, this is advisable. A cold suppository may cause discomfort or spasm upon insertion. It is enough to hold the closed package in your hand for 1-2 minutes or leave it at room temperature for a short time so that the base softens slightly, but does not lose its shape.
Have storage rules changed in 2026-2026?
⚠️ Attention: Manufacturers can update instructions and technologies for stabilizing the drug. Always check the paper instructions included in the specific package that you purchased at the pharmacy, since the conditions may vary slightly depending on the batch of release.
How can you tell that a candle has deteriorated visually?
Main signs: change in color (appearance of gray or dark spots), the presence of oily discharge on the surface of the candle or inside the blister, deformation of the shape, cracks, the appearance of a sharp rancid odor of the fatty base.
