| Cenforce 120 Mg medication is available only by prescription and is designed to help control your symptoms. During sexual stimulation, sildenafil relaxes the smooth muscle of the penis, which allows blood to flow more easily. As the blood flows to the penis, it is released nitric oxide, which is a chemical that helps activate cyclic guanylate cyclase, which leads to increased levels of cyclic guanylate monophosphate in the corpus cavernosum. Sildenafil is available in tablet form and can be taken at any time before you start sexual activity. You should also take Cenforce 120 Mg medicine with or without food. Do not take more than one dose of the medicine in 24 hours, and you should talk to your doctor if you experience chest pain while you are using the drug. Before you start taking sildenafil, you should tell your doctor if you have any kidney or liver problems.
