Suhagra 100 is a medication commonly used to treat erectile dysfunction (ED) in men. Its active ingredient is sildenafil citrate, which is also the active ingredient in Viagra. Sildenafil works by increasing blood flow to the penis, helping to achieve and maintain an erection during sexual activity. It is typically taken about 30 minutes to an hour before sexual activity. The recommended dosage can vary, so it’s important to follow your healthcare provider’s instructions.
