Cenforce 200 is a prescription drug that is used to treat erectile dysfunction. It must be taken at least 30 minutes before sexual activity, but can last up to 4 hours. If used properly, Cenforce 200 can help you achieve an erection up to four hours after taking it. To maximize your benefits from Cenforce 200, take it with a light meal and a full glass of water. The drug begins working as soon as it is ingested, and it will last for up to four or five hours. The drug works by inhibiting the PDE-5 hormone, which is a precursor to CGMP. The PDE-5 inhibitor in Cenforce 200 will stop CGMP production, which is the source of erection trouble.
