Levitra (generic name: vardenafil; brand names include: Vivanza / Yaila) is a prescription medicine that is used to treat erectile dysfunction (ED) and can help you get and keep a quality erection, so that you can make the most of each sexual experience.

Levitra is one of the most widely used ED medicines.

Levitra is offered in four different strengths:

Levitra standard dose 20 mg
Levitra extra strength 40 mg
Levitra extra high strength 100 mg
Levitra low dose 10 mg

You should always start with the lowest dosage and then adjust it according to your response. Levitra works as as-needed medication, meaning it should be taken prior to sexual activity.

The efficacy of Levitra was shown in clinical trials. You may notice improvements in both erection hardness and your ability to maintain your erection during sex.

Like other ED drugs, Levitra alone will not give you an instant erection. Sexual stimulation is necessary for an erection to happen. For most men, Levitra did not cause an erection for longer than they were sexually stimulated.

What Levitra does:

The active ingredient in Levitra works specifically on the chain of events that occur in the penis during arousal and belongs to a class of drugs called PDE-5 inhibitors. It works by increasing blood flow to the penis to improve erectile function. Once a man has completed sexual activity, blood flow to his penis should decrease and his erection should go away.

Levitra has been clinically shown to improve erectile function even in men who had other health problems, including diabetes, prostate surgery, and high blood pressure.

Levitra is both for men who need a little help once in a while and men who need more frequent help.

Recommendations

Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take Levitra exactly as directed.

The usual dosage of Levitra is one tablet taken 25 to 60 minutes before sexual activity. With sexual stimulation, you may achieve an erection anywhere from 25 minutes up to 24 hours after taking Levitra. Swallow one tablet with a glass of water. You can take Levitra with or without food, but preferably not after a heavy or high-fat meal.

Do not take more than one dose in any 24 hour period.

Avoid drinking large quantities of alcohol and grapefruit juice; it may interfere with your medicine.

Store this medicine in a cool, dry place, away from direct heat and light.

you are allergic to any medicines;
you are taking or have recently taken nitrates such as nitroglycerin;
you have a physical abnormality of your penis; liver or kidney problems; angina, heart disease or a low blood pressure; or you have recently suffered a stroke.
