Thus, because of European Union trade rules, parallel imports might result in Vivanza sold next to Levitra in the EU. An orally disintegrating form, marketed as Staxyn and Levitra Soft, has been gaining approvals in countries such as the United States[11] and Canada.
The US Food and Drug Administration (FDA) has found vardenafil and other synthetic PDE5 inhibitors in numerous products marketed as "herbal" supplements or "all natural" products for male enhancement.
Be careful driving or operating machinery until you know how LEVITRA affects you. LEVITRA tablets may cause dizziness or faintness in some patients. The ability to drive and/or operate machinery may be impaired. If you drink alcohol, dizziness or faintness may be worse. Tell your doctor or pharmacist as soon as possible if you do not feel well while you are taking LEVITRA.
LEVITRA helps most men with erectile dysfunction, but it may have unwanted side effects. Sometimes they are serious, most of the time they are not. You may need to stop taking the tablets or have medical treatment if you get some of the serious side effects. Tell your doctor if you notice any of the following and they worry you: headache, flushing, dyspepsia (heartburn), nausea, dizziness or light-headedness, a stuffy or runny nose, sensitivity of the eye to sunlight, high or low blood pressure, stiffness in muscles, pain in the joints, rash, stomach or abdominal pain. These are the more common side effects of LEVITRA.
They are usually mild and short-lived. Very rarely, your erection may persist for longer than usual. If your erection continues for longer than four hours, or if you have a painful erection, you should seek medical attention. Tell your doctor immediately, or go to the accident and emergency department at your nearest hospital if you notice any of the following: severe chest pain, angina, irregular heart beats, loss of consciousness. You may need urgent medical attention or hospitalization. ^ a b c d "Levitra (vardenafil hydrochloride) tablets, for oral use Initial U.S. Approval: 2003". ^ "Levitra (Vardenafil) is A Drug Used to Treat Erectile Problems in Men" (in German).

The frequent vardenafil-specific side-effect is nausea; the infrequent side effects are abdominal pain, back pain, photosensitivity, abnormal vision, eye pain, facial edema, hypotension, palpitation, tachycardia, arthralgia, myalgia, rash, itch, and priapism. One possibly serious, but rare, side effect with vardenafil is heart attack. Also, in rare cases, vardenafil use may cause priapism, a very painful emergency condition that can cause impotence if left untreated. In October 2007, the U.S. Food and Drug Administration (FDA) announced that a warning about possible deafness (sudden hearing loss) would be added to the drug labels of vardenafil, and other PDE5 inhibitors.

They may differ from the information contained in this leaflet. The dose ranges from 5 mg to 20 mg. Your doctor will determine the correct dose for you depending on your condition and response. Take your dose of LEVITRA 25 to 60 minutes before you wish to have sex. Swallow the tablet whole with a glass of water.
Sexual stimulation is required for a natural response to treatment with LEVITRA. The medicine may be taken anywhere between 15 minutes to up to 5 hours before sexual activity. The amount of time LEVITRA takes to start working varies from person to person, but it normally takes between 25 to 60 minutes. If LEVITRA does not help you get an erection, or if your erection does not last long enough to complete sexual intercourse, tell your doctor. In these cases, your doctor may need to adjust your dose.
If you get an angina attack while taking LEVITRA, do not take nitrate medicines to relieve the pain. Make sure that your doctor knows you are taking LEVITRA. Do not give your LEVITRA tablets to anyone else, even if they have the same condition as you. Drinking alcohol can temporarily impair the ability to get an erection. To reduce impairment do not drink large amounts of alcohol before sexual activity. "Unapproved Pharmaceutical Ingredients Included in Dietary Supplements Associated With US Food and Drug Administration Warnings". Vardenafil (Levitra) is a medication used to treat erectile dysfunction. It works by blocking an enzyme that stops the flow of blood to the penis.
Other side effects not listed above may also occur in some patients. Tell your doctor if you notice anything else that is making you feel unwell. Do not be alarmed by this list of possible side effects. You may not experience any of them. Reprinted with permission from Dialog Medical, DialogMedical.com.

Vardenafil, sold under the brand name Levitra among others, is a medication that is used for treating erectile dysfunction. Vardenafil's indications and contraindications are the same as with other PDE5 inhibitors; it is closely related in function to sildenafil citrate (Viagra) and tadalafil (Cialis). The difference between the vardenafil molecule and sildenafil citrate is a nitrogen atom's position and the change of sildenafil's piperazine ring methyl group to an ethyl group.
Tadalafil is structurally different from both sildenafil and vardenafil. Vardenafil's relatively short effective time is comparable to but somewhat longer than sildenafil's. Despite the structural differences between vardenafil and sildenafil, they both show similar ocular side effects due to their similar selectivity overlap with PDE6, an enzyme found in the eye. Beyond its indications for erectile dysfunction, vardenafil may be effective in the treatment of premature ejaculation, where it may significantly increase the time from penetration to ejaculation. The generic levitra 20 common, adverse drug reactions (side effects) are the same as with other PDE5 inhibitors. When a man is sexually aroused, nerve endings and cells in the penis release nitric oxide, which activates an enzyme called guanylate cyclase. This enzyme causes the production of a chemical called cyclic guanosine monophosphate (cGMP). cGMP relaxes the blood vessels in the penis, allowing more blood to flow into it, resulting in an erection.

|---|---|---|---|
| Onset of action | 25-30 minutes | 30-60 minutes | 30-60 minutes |
| Duration | Up to 4-5 hours | Up to 4 hours | Up to 36 hours |
| Food interactions | Less affected by food | Delayed if taken after heavy meals | Less affected by food |
| Side effect profile | Similar to others, with possible visual disturbances | Similar, with some headache | Longer-lasting effect |
Vardenafil blocks an enzyme called phosphodiesterase type 5 ( Vardenafil, otherwise known as Levitra, is approved by the FDA for 2 uses including Erectile dysfunction and Impotence . Vardenafil is used to treat impotence in men and high blood pressure in the lungs. During an erection, a chemical called nitric oxide is released, which triggers an enzyme called guanylate cyclase and causes increased levels of a molecule called cyclic guanosine monophosphate (cGMP). This increases blood flow to the penis, leading to an erection.
Vardenafil helps by blocking the action of an enzyme (PDE5) that breaks down cGMP in the penis. This means that when sexually stimulated, vardenafil will increase the levels of cGMP, resulting in Vardenafil helps increase blood flow to the penis, which can cause an erection. It does this by blocking an enzyme, PDE5, which breaks down a chemical called cGMP. cGMP helps relax the blood vessels leading to the penis and increases blood flow. When PDE5 is blocked, more cGMP is available to help keep these blood vessels open and increase blood flow.
Vardenafil should not be used by people taking nitrate medications, because combining them with vardenafil might provoke potentially life-threatening hypotension (low blood pressure). Further, vardenafil causes lengthening of the QT interval. Therefore, it should not be taken by people taking other medications that affect the QT interval (such as amiodarone). Vardenafil was co-marketed by Bayer Pharmaceuticals, GlaxoSmithKline, and Schering-Plough under the brand name Levitra. As of 2005, the co-promotion rights of GSK on Levitra have been returned to Bayer in many markets outside the US. This helps a man achieve and maintain an erection.
