Cenforce 200 mgcontains sildenafil, a medicine commonly used to treat erectile dysfunction (ED) in adult men. It works by improving blood flow to the penis when sexual stimulation occurs, helping support an erection. Because 200 mg is a high dose, it should only be used under guidance from a qualified healthcare professional. Cenforce may interact with nitrates and certain other medicines, so discussing your medical history and current medications is important. Common side effects may include headache, flushing, indigestion, nasal congestion, and dizziness. Always follow the prescribed dosage and seek medical attention for severe or persistent side effects.
