Cenforce D is commonly marketed as a combination product for men experiencing erectile dysfunction (ED) and premature ejaculation (PE). Products with this name commonly contain sildenafil and dapoxetine, although formulations can vary. Checking the packaging for the exact ingredients and strengths is therefore important. Sildenafil is a PDE5 inhibitor that improves blood flow to the penis during sexual stimulation. Dapoxetine is a short-acting SSRI used in some countries to help delay ejaculation. Because these medicines have different effects, treatment decisions should consider whether a man actually has both ED and PE rather than using a combination product automatically.
