Zenegra 50 mg is a medication used to treat erectile dysfunction (ED) in men. Its active ingredient is sildenafil citrate, which belongs to the PDE5 inhibitor class. Sildenafil works by relaxing blood vessels in the penis, improving blood flow during sexual stimulation, and helping to achieve and maintain an erection. The 50 mg dose is commonly considered a standard starting dose. Doctors may prescribe this strength to evaluate how well the patient responds and to monitor side effects. Depending on effectiveness, the dose may be adjusted to 25 mg or 100 mg.
