Malegra DXT should not be taken with grapefruit or grapefruit juice because grapefruit can interfere with the metabolism of Sildenafil (100 mg) and Dapoxetine (60 mg) in the body. Why Avoid Grapefruit with Malegra DXT? Increased Drug Concentration – Grapefruit inhibits the CYP3A4 enzyme, which is responsible for breaking down Sildenafil and Dapoxetine. This can lead to higher drug levels in the bloodstream, increasing the risk of side effects. Higher Risk of Side Effects – Side effects such as dizziness, headache, nausea, flushing, and low blood pressure may become more severe. Delayed Drug Elimination – The prolonged presence of the drug in the body can lead to unexpected prolonged effects, which may be unsafe. What to Do Instead? Take Malegra DXT with water instead of grapefruit juice. Avoid grapefruit products for at least 24 hours before or after taking the medication.
