Cenforce 200 contains a very high dose of sildenafil, a PDE5 inhibitor used specifically to treat erectile dysfunction (ED). It works by increasing blood flow to the penis during sexual stimulation, but it is not a general wellness, fitness, energy, or performance supplement. Using it without a medical need can expose you to unnecessary risk. At 200 mg, the dose is already at the upper end of sildenafil therapy, and side effects are more likely. These can include headache, flushing, dizziness, low blood pressure, visual disturbances, nasal congestion, and indigestion.
