Cenforce 100 is typically safe to use once every 24 hours, as recommended by healthcare professionals. Taking it more frequently can increase the risk of side effects like headaches, low blood pressure, or prolonged erections. The medication stays active in the body for about 4–6 hours, but its effects on the system can last longer. Safe usage depends on your age, overall health, and other medications you may be taking. Always follow your doctor’s instructions and never exceed the prescribed dose. Regular medical checkups can ensure Cenforce 100 remains a safe and effective option for managing ED.
