Record heat can damage medication

The German Weather Service recently announced that June 2019 is the hottest June since weather recording started. In view of the high temperatures, care should be taken to ensure that medicines are stored correctly, because heat and sunlight can render some medicines unusable.

The Federal Association of Pharmaceutical Manufacturers (BAH) draws attention to the fact that the current temperatures can harm many medications. Most medicines are best kept in a cool and dry environment. Dr. explains what has to be taken into account when storing medicines at record temperatures. Elmar Kroth, Managing Director Science at BAH.

Do not leave medicines in the car in hot weather

"Medicines are sensitive products," emphasizes the expert. Excessively high storage temperatures and direct sunlight can impair their quality. Therefore, medication should not be stored in places that are exposed to direct sunlight. The specialist also advises against storage in the car. Temperatures are sometimes reached there, which can damage the media.

Not all medicines are in good hands in the fridge

You should also refrain from simply putting all medication in the fridge, because many medicines cannot tolerate this. Dr. According to Kroth, only the medication should be stored in the refrigerator, where such storage is expressly recommended on the package insert. Other medicines can be damaged if the storage temperature and humidity are too low in the refrigerator.

Don't ignore changes

If a medication has changed in any way, it is not advisable to take it, the BAH recommends. In case of doubt, the specialist staff can be interviewed in a pharmacy. The medication should no longer be taken for the following exemplary changes that have occurred during storage:

  • Tablets: discoloration, cracks or odor.
  • Juices and injection solutions: flocculation or cloudiness.
  • Ointments and gels: liquefaction, discoloration or odor.

Note leaflet

Most medicines are best stored at a room temperature between 15 and 25 degrees Celsius. "Information on proper storage - including the storage temperature - can be found on the outer packaging of the drug and in the package leaflet," says Dr. Kroth. (vb)
