Levitra (Vardenafil)

A household spoon is not an accurate measuring device and may cause you to take the wrong dose. Ask your pharmacist to recommend an appropriate measuring device. Tell your healthcare provider about all of your health conditions and any prescription or over-the-counter (OTC) medicines, vitamins/minerals, herbal products, and other supplements you are using. This will help them determine if sildenafil is right for you. In particular, make sure that you discuss any of the following.

Heart problems, such as heart rhythm problems, chest pain, or heart failure Heart attack, stroke, or heart surgery within the past six months High blood pressure that is still too high despite taking medicines for it Peyronie's disease, or a penis with an abnormal curve or shape An erection lasting longer than four hours A blood disorder, such as sickle cell anemia An inherited eye disease called retinitis pigmentosa Vision loss, or a problem with the nerve between your eyes and brain (optic nerve) Health conditions or factors that raise the risk of optic nerve problems, such as diabetes, high cholesterol, smoking, being older than 50, or having a “crowded disc,” which is something an eye doctor may see in an eye exam Pulmonary veno-occlusive disease, a condition where blood vessels in the lungs are blocked It is not known if or how sildenafil could affect pregnancy or harm an unborn baby. Tell your healthcare provider if you are or plan to become pregnant. Tell your healthcare provider if you are breastfeeding or plan to breastfeed. Your healthcare provider will advise you if you should take sildenafil while breastfeeding.

How will my doctor determine whether Viagra or Levitra is better for me?

If you take sildenafil after you eat a high-fat meal, such as a burger and fries, it may take longer to start working. Your healthcare provider may recommend limiting or avoiding grapefruit while taking sildenafil. Grapefruit or grapefruit juice can raise sildenafil levels in your body, which can increase the risk of side effects. There are no known interactions between sildenafil and alcohol. Always tell your healthcare provider about any prescription or over-the-counter (OTC) medicines, vitamins/minerals, herbal products, and other supplements you are using. It works by increasing blood flow to the penis during sexual stimulation. This increased blood flow can cause an erection.

• Vardenafil 20mg can improve quality of life by restoring sexual confidence.
• It does not protect against sexually transmitted infections.

Vardenafil does not cure erectile dysfunction or increase sexual desire. Vardenafil does not prevent pregnancy or the spread of sexually transmitted diseases such as human immunodeficiency virus (HIV).

Vardenafil comes as a tablet and a rapidly disintegrating (dissolves in the mouth and is swallowed without water) tablet to take by mouth.

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 common, adverse drug reactions (side effects) are the same as with other PDE5 inhibitors.

Serious side effects

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.

When to Seek Medical Attention

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. It is usually taken as needed, with or without food, 60 minutes before sexual activity. Vardenafil usually should not be taken more often than once every 24 hours. If you have certain health conditions or are taking certain medications, your doctor may tell you to take vardenafil less often. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Do not take more or less of it or take it more often than prescribed by your doctor. If you are taking the rapidly disintegrating tablet, check the blister pack before you take your first dose.

Is Vardenafil or Viagra More Effective for You?

In particular, make sure that you discuss if you are using any of the following before taking sildenafil. Tell your healthcare provider about all medicines that you take or have recently taken. This may not be a complete list of medicines that can interact with sildenafil. If you or someone else has used too much sildenafil, get medical help right away, call 911, or contact a Poison Control center at 800-222-1222. For this use, sildenafil is used only when needed.

Erectile dysfunction agents

Take it as your healthcare provider recommends, which is usually between 30 minutes to four hours before planned sexual activity. Do not take double or extra doses. For this use, take sildenafil as your healthcare provider recommends, which is usually three times a day. If you miss a dose, take it as soon as you remember. If it is almost time for your next dose, skip the missed dose and only take the next dose.

Does Food Affect How These PDE5 Inhibitors Work?

Ask your healthcare provider if you are unsure what to do after a missed dose. This survey is being conducted by the WebMD marketing sciences department. 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. Do not use any of the medication from the pack if any of the blisters are torn, broken, or do not contain tablets. Follow the package directions to remove the tablet from the blister package. Do not try to push the tablet through the foil. After you remove the tablet from the blister package, immediately place it on your tongue and close your mouth. Do not take the rapidly disintegrating tablet with water or other liquids. Your doctor will probably start you on an average dose of vardenafil tablets and increase or decrease your dose depending on your response to the medication. If you are taking the rapidly disintegrating tablets, your doctor will not be able to adjust your dose because the rapidly disintegrating tablets are only available in one strength. If you need a higher or lower dose, your doctor may prescribe the regular tablets instead. Tell your doctor if vardenafil is not working well or if you are experiencing side effects. Vardenafil rapidly disintegrating tablets cannot be substituted for vardenafil tablets. Be sure that you receive only the type of vardenafil that was prescribed by your doctor. Ask your pharmacist if you have any questions about the type of vardenafil you were given.

This medication may be prescribed for other uses; ask your doctor or pharmacist for more information.
