Malegra FXT is a combination medication that contains two active ingredients: Sildenafil citrate (100 mg) – A PDE5 inhibitor, which improves blood flow to the penis, helping to achieve and maintain an erection during ****** stimulation. This is the same active ingredient found in medications like Viagra. Dapoxetine (60 mg) – A selective serotonin reuptake inhibitor (SSRI), primarily used to treat premature ejaculation (PE). Dapoxetine works by increasing serotonin levels in the brain, helping to delay ejaculation. Onset of Action for Erectile Function: Sildenafil (in Malegra FXT) typically begins to work within 30 to 60 minutes after ingestion. However, it’s most effective when taken about 1 hour before ****** activity. For most men, the effects of sildenafil can last for about 4 to 6 hours. Malegra FXT (for premature ejaculation) works relatively quickly too, usually taking about 1 hour to start showing effects. Its primary role in Malegra FXT is to delay ejaculation, rather than directly affect erectile function. When Does Malegra FXT Begin to Show Effects on Erectile Function? Erection-Related Effects: You should begin to notice an effect within 30 to 60 minutes after taking Malegra FXT, but the peak effectiveness is often observed around the 1-hour mark. Premature Ejaculation Effects: The combination of sildenafil and dapoxetine also helps men with both ED and PE. Sildenafil works on erectile function, while dapoxetine helps delay ejaculation.
