If Cenforce 150 mg contains sildenafil, it works the same basic way as other sildenafil products: During sexual stimulation, your body releases nitric oxide, which increases cGMP and relaxes the blood vessels in the penis. Sildenafil blocks the enzyme PDE-5, which normally breaks down cGMP. This allows more blood to flow into the penis and helps produce/maintain an erection. D DailyMed Cenforce 150 mg  It doesn't cause an automatic erection and doesn't increase sexual desire; sexual stimulation is still necessary. D DailyMed Important about 150 mg 150 mg is higher than the usual maximum recommended sildenafil dose of 100 mg for ED. Standard prescribing information recommends 50 mg for most patients, adjustable to 25–100 mg, and no more than once per day. D DailyMed So I would not recommend taking 150 mg on your own, particularly if you haven't already been prescribed that dose. If you want, I can explain what happens with Cenforce 150 after a heavy meal, how long it lasts, and how it compares with Cenforce 100.
