2 min read 27-02-2025

Nystatin is a common antifungal medication used to treat various fungal infections, such as oral thrush and yeast infections. Many people wonder about the proper storage of this medication, specifically whether it needs to be refrigerated. The short answer is: it depends on the formulation.

Nystatin Oral Suspension: Refrigeration is Key

Nystatin oral suspension (liquid) must be refrigerated. This is crucial to maintain its potency and prevent the growth of bacteria or other microorganisms that could contaminate the medication. Always check the label of your specific nystatin oral suspension; the manufacturer's instructions will explicitly state the need for refrigeration. Discard any unused portion after the expiration date printed on the label.

Proper Storage of Nystatin Oral Suspension

Refrigerate: Keep the bottle in the refrigerator between 36°F and 46°F (2°C and 8°C).
Shake Well: Always shake the bottle well before each dose to ensure even distribution of the medication.
Discard: Throw away any unused medication after the expiration date. Do not use medication that has changed color or consistency.

Nystatin Cream, Ointment, and Tablets: Refrigeration Not Typically Required

Unlike the liquid suspension, nystatin creams, ointments, and tablets generally do not require refrigeration. These formulations are typically stable at room temperature. However, it's always best to:

Check the Label: Always refer to the specific instructions on your product label for the most accurate storage information.
Store in a Cool, Dry Place: Keep the medication in a cool, dry place, away from direct sunlight and excessive heat. Avoid storing it in the bathroom, where moisture and temperature fluctuations are common.
Observe Expiration Date: Do not use the medication after the expiration date printed on the container.

Frequently Asked Questions (FAQs)

What happens if I don't refrigerate nystatin oral suspension?

Conclusion: Always Check the Label

While nystatin oral suspension requires refrigeration, creams, ointments, and tablets generally do not. However, the best practice is always to consult the specific instructions provided on your medication's label for accurate storage information. Proper storage ensures the medication's efficacy and safety. If you have any questions or concerns, consult your pharmacist or healthcare provider. They can provide personalized guidance and address any specific concerns you might have about your medication. Remember to always follow the directions on your prescription label.
