If Malegra FXT contains sildenafil plus fluoxetine, the timing depends on both ingredients. For the sildenafil component, blood levels typically peak about 30–120 minutes after an oral dose, with a median of around 60 minutes when taken fasting. A high-fat meal can delay sildenafil's peak by about an hour, so the effect may take Malegra FXT to develop. The fluoxetine component does not have the same rapid “peak effect” for premature ejaculation; its effects develop differently and are generally assessed over longer periods. Also, Malegra FXT is a combination product, so don't adjust the dose or take an additional tablet to make it work faster without medical advice.
