Silagra contains sildenafil citrate and is used to treat erectile dysfunction (ED) in adult men. It works by improving blood flow to the penis during sexual stimulation, helping support an erection. Silagra does not increase sexual desire and should be used according to professional medical guidance. Common side effects may include headache, flushing, indigestion, dizziness, and nasal congestion. Sildenafil should not be taken with nitrate medicines because the combination can dangerously lower blood pressure. For recurring erectile difficulties, consulting a qualified healthcare professional can help identify underlying causes and appropriate treatment options
