What are Levitra Tablets?
Levitra tablets contain the active ingredient vardenafil, which belongs to a class of drugs called phosphodiesterase type 5 (PDE5) inhibitors. They are used to treat erectile dysfunction (ED) in men by increasing blood flow to the penis during sexual stimulation.

How does it work?
Levitra tablets work by blocking the action of an enzyme called phosphodiesterase type 5 (PDE5), which is responsible for breaking down a natural chemical in the body called cyclic guanosine monophosphate (cGMP). During sexual stimulation, cGMP causes the blood vessels in the penis to dilate, allowing more blood to flow into the penis and resulting in an erection. By blocking PDE5, Levitra tablets increase the levels of cGMP, which enhances the effects of sexual stimulation and helps to achieve and maintain an erection.
How to take it?
Levitra tablets should be taken orally, with or without food, about 30 minutes to an hour before sexual activity. The usual starting dose is 10mg, which can be increased or decreased depending on how well it works and any side effects experienced. The maximum recommended dose is 20mg per day. It's important to follow the dosage instructions provided by your doctor or pharmacist and not take more than the recommended dose. Do not take Levitra with grapefruit or grapefruit juice, as this can increase the risk of side effects. It's also important to avoid drinking too much alcohol, as this can reduce the effectiveness of the medication. If you have any questions or concerns about how to take Levitra, talk to your doctor or pharmacist.
