Using Cenforce 100 for the first time requires understanding how it works and how to use it safely. Cenforce 100 contains sildenafil citrate, which helps improve blood flow to the penis, aiding in achieving and maintaining an erection during sexual stimulation. It should be taken about 30–60 minutes before intercourse and not more than once in 24 hours. Avoid heavy meals, alcohol, and grapefruit products before taking it, as these can reduce its effectiveness. Side effects may include headache, flushing, dizziness, or upset stomach. Always consult a doctor before starting Cenforce 100 to ensure it’s safe based on your health condition and medications.
