Cenforce 200mg should be used exactly as prescribed by a doctor. Take one tablet with water about 30 to 60 minutes before sexual activity. Avoid taking more than one dose within 24 hours. It works best on an empty stomach or after a light meal, as heavy or fatty foods may delay its effect. Sexual stimulation is needed for the medicine to work properly. Avoid alcohol and grapefruit juice because they may increase side effects like dizziness or headache. Men with heart problems, low blood pressure, or nitrate medication use should consult a healthcare professional before taking this medicine.
