What if you use out of date efudix?

Using out-of-date Efudix (fluorouracil) may reduce its effectiveness in treating skin conditions like actinic keratosis or superficial basal cell carcinoma. Additionally, expired medications can sometimes lead to unexpected side effects or reduced safety. It's important to consult a healthcare professional before using any expired medication to ensure proper treatment and avoid potential risks. Always check expiration dates and store medications as directed.
