The effect of Malegra FXT typically lasts around 4 to 6 hours, during which a man may experience improved erectile function whenever sexually stimulated. Fluoxetine’s role is more subtle—it helps reduce performance anxiety and delay ejaculation by increasing serotonin levels in the brain, which can positively influence sexual satisfaction. Clinical studies specifically on Malegra FXT are limited, but research on its individual components is extensive. Sildenafil has been proven effective and safe for ED in numerous trials, while Fluoxetine is established for treating depression and premature ejaculation.
