Before taking Cenforce 200 mg, which contains sildenafil citrate for treating erectile dysfunction, consult your doctor to discuss your medical history, especially if you have heart issues or are on nitrates. Follow the prescribed dosage and take it about 30-60 minutes before sexual activity for the best results. Be mindful of potential side effects like headaches, flushing, and dizziness. Avoid exceeding one tablet per day, and limit alcohol intake, as it can reduce the medication's effectiveness and increase the likelihood of side effects. Always prioritize safety and proper guidance from a healthcare professional.
