The pharmaceutical in Levitra is called Vardenafil, and it belongs to a class of drugs called PDE5 Inhibitors. Levitra helps the penis during it’s natural process of arousal. The specific mechanism of action is the facility of blood flow into the two chambers of the penis, and this is done by relaxing muscles in blood vessels. Levitra should not be mixed with alcohol because serious interactions can occur. Levitra can cause erections that are either painful, erections that last for longer than 4 hours, or both.
If any erection lasts longer than four hours medical attention should be immediately sought. During sexual activity if you have numbness or tingling in the arms, chest, or neck then you could be having a serious reaction to Levitra, and need to seek medical treatment. You should not take Levitra if you are also taking nitrates for chest pain or heart problems. You should only take Levitra if you are physically healthy enough to partake in sexual activity beforehand. Levitra is similar to Viagra in mechanism of action, and also in side effects. Levitra can cause a decrease of blood pressure to the optic nerve which can result in a partial or total loss in vision. If vision problems arise you should immediately stop taking Levitra and contact your doctor. Levitra can be taken with or without food. Levitra is usually taken about an hour before participating in sexual activity. Levitra is usually taken in a single dosage of twenty milligrams, but you should take Levitra exactly as prescribed by your physician, and not in smaller or larger amounts.
When you begin taking Levitra you may be started at a ten milligram dosage, and then increased to the maximum dosage of twenty milligrams based on efficiency and tolerance of the initial dosage amount. Patients that are on stable alpha blocker therapy may be able to take Levitra, but at a smaller dosage of something closer to five milligrams. Also adults that are 65 years or older commonly start at a lower dosage as well. Sexual stimulation is a requirement for therapy to be effective with Levitra, and erections will not occur by simply dosing Levitra alone. Because of the fact that Levitra is taken as needed then there is no need to take a dose if you missed one, and no more than one dose a day should be taken. You should not take other impotence drugs or herbs concurrently with Levitra because of the risk of dangerously low blood pressure.
