Cenforce 120 is a medication used to treat erectile dysfunction (ED) in men. It contains sildenafil citrate as its active ingredient, which works by relaxing the blood vessels in the penis, allowing for increased blood flow and thus facilitating an erection. The recommended dosage of Cenforce 120 is one tablet per day, to be taken orally with water at least 30 minutes before sexual activity. It should not be taken with alcohol or fatty foods, as this can decrease its effectiveness. Side effects of Cenforce 120 may include headache, dizziness, nausea, and flushing, but these are generally mild and temporary. It is important to consult a healthcare provider before taking Cenforce 120, especially if you have a history of heart or liver problems, or are taking other medications.
