Sildigra Black Force 200 mg is a medication used to treat erectile dysfunction (ED) in men. It contains the active ingredient sildenafil citrate, which is a phosphodiesterase type 5 (PDE5) inhibitor. Sildenafil works by increasing blood flow to the penis during sexual stimulation, helping men achieve and maintain an erection. The "200 mg" strength indicates the dosage of sildenafil citrate in each tablet. This is a higher dose compared to standard doses of sildenafil, which are typically 25 mg, 50 mg, or 100 mg. It's important to note that higher doses of sildenafil, such as 200 mg, may carry an increased risk of side effects and interactions. Taking a higher dose of sildenafil without proper medical guidance can be risky. Common side effects of sildenafil include headache, flushing, nasal congestion, indigestion, and visual disturbances. In rare cases, sildenafil can also cause more serious side effects, especially at higher doses.
