Silagra 100 mg is a medication used to treat erectile dysfunction (ED) in men. It contains sildenafil citrate, which belongs to a class of medications called phosphodiesterase type 5 (PDE5) inhibitors. Silagra works by increasing blood flow to the penis during sexual stimulation, thereby helping men achieve and maintain an erection. The usual recommended dose of Silagra 100 mg is one tablet taken orally with a full glass of water, approximately 30 minutes to 1 hour before sexual activity. It's important not to exceed the recommended dosage of one tablet per day. As with any medication, Silagra 100 mg may cause side effects, including headache, flushing, indigestion, nasal congestion, dizziness, and visual disturbances. It's essential to consult a doctor before taking this medication, especially if you have any underlying health conditions or are taking other medications.
