amagra 100 is a medication used to treat erectile dysfunction (ED) in men. It contains sildenafil citrate, which is the same active ingredient found in Viagra. Sildenafil citrate works by increasing blood flow to the penis, helping men achieve and maintain an erection when sexually aroused. Kamagra 100 should only be used under the guidance of a healthcare provider, as it can interact with other medications and may not be suitable for everyone, especially those with certain medical conditions. Common side effects may include headaches, flushing, indigestion, and nasal congestion.
