Levitra 20mg: Active Ingredient and Mechanism of Action

Levitra 20mg contains vardenafil as its active ingredient. Vardenafil belongs to a class of medications called phosphodiesterase-5 (PDE5) inhibitors.

How Vardenafil Works

Vardenafil enhances the effects of nitric oxide, a naturally occurring substance in the body. Nitric oxide relaxes the blood vessels in the penis, increasing blood flow. This improved blood flow is crucial for achieving and maintaining an erection. The inhibition of PDE5 by vardenafil prolongs the effects of nitric oxide, leading to a stronger and more sustained erection.

Important Considerations

Remember to consult your doctor before using Levitra 20mg, especially if you have underlying health conditions or are taking other medications. They can assess your suitability for this medication and discuss potential side effects and interactions.

Levitra 20mg: Dosage and Administration

Take Levitra 20mg exactly as prescribed by your doctor. The usual starting dose is 10mg, taken about 60 minutes before sexual activity. Your doctor may increase this to 20mg, or decrease it to 5mg, depending on your response and any side effects.

Swallow the tablet whole with a glass of water. Do not crush, chew, or break the tablet. You can take Levitra with or without food, but note that a high-fat meal may delay the onset of action.

Do not exceed the maximum recommended dose of 20mg in a 24-hour period. Only take one tablet per day.

If you experience side effects, contact your doctor immediately. Common side effects include headache, flushing, nasal congestion, and indigestion. More serious side effects are rare but require prompt medical attention.
