Nystatin is a common antifungal medication used to treat various fungal infections. Understanding its proper storage is crucial to ensure its effectiveness. So, does nystatin need to be refrigerated? The answer isn't a simple yes or no. It depends on the formulation of the nystatin.

Nystatin Cream and Ointment Storage

Does nystatin cream need refrigeration? No, nystatin cream and ointment generally do not require refrigeration. They're usually stable at room temperature. However, always check the specific instructions on your product's label. Store in a cool, dry place, away from direct sunlight and excessive heat. Avoid extreme temperatures, as this can affect the medication's potency.

Nystatin Oral Suspension Storage

Does liquid nystatin need to be refrigerated? Yes, once reconstituted (mixed with water as per instructions), nystatin oral suspension should be refrigerated. The manufacturer's instructions will specify the storage temperature and shelf life once mixed. Refrigeration helps prevent the growth of bacteria and maintain the medication's potency. Discard any unused suspension after the indicated timeframe on the label. This is crucial to prevent the risk of infection.

How Long is Nystatin Good For After Reconstitution?

The shelf life of reconstituted nystatin oral suspension varies depending on the manufacturer and specific product. Always consult the label for the exact expiration date. Generally, it is safe for only a short period, usually 7 to 10 days, once mixed.

Important Considerations for Nystatin Storage

Always check the label: The most reliable information regarding storage comes directly from the product label. Read it carefully and follow the instructions precisely.
Observe expiration dates: Never use nystatin after its expiration date. Expired medication may be less effective or even harmful. Proper disposal is crucial.
Keep out of reach of children: This is a vital safety precaution for all medications. Store nystatin in a secure location inaccessible to children.
Avoid extreme temperatures: Exposure to extreme heat or cold can compromise the medication's effectiveness.

Proper Disposal of Nystatin

When your nystatin is expired or no longer needed, proper disposal is essential. Never flush medication down the toilet or throw it in the trash. Check with your local pharmacy or waste management agency for guidance on safe disposal methods. They may have a medication take-back program.
