Many people prefer to buy medicines in advance. Be it a specific medication they need to take regularly or the drug for common flu. It is natural to keep them stored in advance. Most of the medicines can be safely stored at room temperature. This is because they can remain stable and work well regardless of the temperature they are stored at. However, this is not the case with all the medicines. Some medications are required to be refrigerated to maintain their stability.

You might have noticed how some medicines are kept in a refrigerator in a pharmacy but are safe to be kept at room temperature by the purchaser. Some have to be frozen at all times to maintain their effectiveness. You will be surprised to know that some medicines can stay at room temperature but have to be refrigerated once you start using them. Vaccines are usually required to be frozen at all times before using.

Reasons for Why Some Medicines Require Refrigeration

The method of storing has a significant impact on the effectiveness and potency of the drugs. If not stored appropriately, the medications can turn toxic and become harmful. Some of the reasons why some medicines require refrigeration:

Maintaining Effectiveness

Medicines that require refrigeration will lose their effectiveness if stored at any other temperature. Every drug/medication that comes on the market is tested several times to ensure its stability at various temperatures for a period. It helps in determining the temperature best for the medication’s chemical stability. In case of improper storage, it can turn toxic.

Maintaining Sterility

To keep your medication free of microorganisms and maintain its sterility, it is integral to refrigerate them. For example, many eye drops need to be refrigerated to prevent breaking down and losing their potency.

Maintaining Form

Many medicines also require refrigeration to maintain their physical form. At room temperature, they can melt even before you get the chance to use them.

Factors That Can Change Medications’ Temperature


Several factors can affect the temperature of your medications. Some of them are-

  • Weather: If you live in a hot place and do not have access to air conditioning, there is a high chance of your medicine getting overheated. This might result in reducing its potency.
  • Inside Your Car: Leaving your medicines inside your car for long periods can increase their chances of becoming less potent. This is because cars can get overheated during the summers, even when standing in the shade. Always store your medicine in a cool, dry place.
  • Travel: While traveling, it is essential to keep your medication properly to maintain its chemical stability. Make sure not to expose it to heat for a long period.
  • Transportation: While transporting medications from one place to another, some drugs that are more susceptible to heat can turn ineffective. Therefore, even during transportation, it is necessary to follow the recommended rules of storing.
