Malegra FXT is commonly marketed as a combination treatment for men experiencing erectile dysfunction (ED) and premature ejaculation (PE). Products sold under this name commonly contain sildenafil, a PDE5 inhibitor, and fluoxetine, an SSRI antidepressant. Because formulations can vary, checking the product label for the exact ingredients and strengths is important. Sildenafil helps improve blood flow to the penis during sexual stimulation, making it easier to achieve and maintain an erection. It does not increase sexual desire. Fluoxetine affects serotonin signaling and is sometimes used off-label to delay ejaculation, although its suitability depends on individual circumstances.
