Super Vilitra contains a combination of two active ingredients: Vardenafil (a phosphodiesterase type 5 inhibitor) and Dapoxetine (a selective serotonin reuptake inhibitor used for premature ejaculation). Grapefruit juice can interact with certain medications, including those containing Vardenafil.

The interaction between grapefruit juice and Vardenafil can lead to an increased concentration of the drug in your bloodstream, which may intensify side effects like dizziness, low blood pressure, headaches, or an increased risk of other adverse effects.

Therefore, it is generally recommended to avoid grapefruit juice while taking Super Vilitra. The specific time to avoid grapefruit juice would be both before and after taking the medication, since grapefruit juice can affect the metabolism of Vardenafil for several hours.

If you're considering taking Super Vilitra, or if you're currently on it, I suggest discussing this with your doctor or healthcare provider to get personalized advice on managing potential interactions.
