Fildena CT 100 does expire. Like all medicines, it has an expiry date printed on the strip/blister pack or box. After that date, the manufacturer no longer guarantees its full potency, stability, or safety. A few points: Check the “EXP” date on the packaging. Do not use tablets that are past expiry, damaged, discolored, unusually soft, or have been stored improperly. Store it in a cool, dry place, away from direct sunlight and moisture. Do not rely on appearance alone to judge whether an expired tablet is safe. If you tell me the expiry month/year printed on your Fildena CT 100 pack and how it has been stored, I can help you assess it. Fildena CT 100 is a medicine used for erectile dysfunction (ED).
