Levitra (vardenafil) is the medication used to treat eractyle disfunction (or impotence). It works by inhibiting the enzyme known as phosphodiesterase type (DE5). DE5 is present in the lining of the blood vessels around corpus cavernosum of the penis. Because of the inhibition, corpus cavernosum gets more blood and that causes the erection.
This medication was introduced to the public shortly after the success of Viagra (sildenafil). Both medications work by the same mechanism, but Levitra works faster and the erection lasts longer than with Viagra. Most patients using Levitra experienced improvement in about half an hour, and the effect lasted for some 5 hours. Another difference is that Levitra can be used by people suffering from many health conditions, including depression, hypertension, diabetes mellitus, spinal cord injury or removed prostate.
Levitra can be found in doses of 2.5 mg, 5 mg, 10 mg and 20 mg. These are much lower doses than in Viagra (available doses are 25, 50 and 100mg) and because of that Levitra is considered to be safer and with less side effects than Viagra.
This is a prescription drug for the treatment of impotence and you should consult the doctor to found out the proper medication and dosage for your case. In most cases, a doctor will recommend the lowest dose of the drug, and increase the dose if the previous one fails to give expected result (erection). If, for some reason, you start to experience some side effects, doctor might decide not to increase the dose of Levitra. Usual procedure is to take Levitra and hour before the sexual activity, for the tablet takes about 30 minutes to start working.
It might be possible to get a prescription for Levitra via online clinics, not only by visiting a doctor. These clinics are free of charge, and the only thing they require is an online questionnaire, regarding your sexual habits, medications used and health condition. Doctors will check your answers and prescribe the drugs, if they think it’s safe for you.
Always make sure to consult a doctor before taking Levitra. At the consult, inform your doctor about the medications, supplements, remedies you have been taking and about your medical condition. Mention all allergies you might have, especially those on some medications.
Do not ever increase the dose of Levitra on your own.
Do not use Levitra with alcohol or heavy food.
Do not use Levitra and other nitrate drugs together.
If your erection lasts for more than 4 hours or if there are any other side effects from the medication – ask for medical help.
