Cenforce 120 tablet is a sildenafil citrate medication used to treat erectile dysfunction (ED) in men. It works by relaxing blood vessels and improving blood flow to the penis during sexual stimulation, helping achieve and maintain a firm erection. This medium-to-high strength dose may be prescribed for men who do not get satisfactory results from lower doses. The tablet is usually taken 30–60 minutes before sexual activity and should not be used more than once daily. Common side effects include headache, flushing, dizziness, and indigestion. Men with heart disease, low blood pressure, or nitrate medication use should consult a doctor before taking Cenforce 120.
