Levitra

The usual recommended dose is one 10 mg tablet taken as needed, 25 to 60 minutes before sexual activity. Levitra (Vardenafil) has been shown to be effective within 15 minutes of taking the tablet, and lasts up to 8 to 10 hours later. As the amount of time Levitra (Vardenafil) takes to work varies from person to person, starting sexual activity at different times after taking the tablet will determine the optimal time for sexual activity. It is not recommended to take more than one dose per day. Your doctor may recommend a dose as low as 5 mg or as high as 20 mg.

Many things can affect the dose of a medication that a person needs, such as body weight, other medical conditions, and other medications. If your doctor has recommended a dose different from the ones listed here, do not change the way that you are taking the medication without consulting your doctor.

Levitra (Vardenafil) may be taken with or without food.

Because alcohol can make it more difficult to get an erection, do not drink large amounts of alcohol before sexual activity. Moderate amounts of alcohol (2 drinks for a 70 kg person) will not interfere with the medication.

It is important to take Levitra (Vardenafil) exactly as prescribed by your doctor. Do not take higher doses of Levitra (Vardenafil) than prescribed by your doctor. Contact your doctor if you do take a higher dose of Levitra (Vardenafil) than prescribed.

Keep Levitra (Vardenafil) out of reach and sight of children. Levitra (Vardenafil) should be stored in its original package, at room temperature between 15°C and 30°C.

If you are taking any of these medications, speak with your doctor or pharmacist. Depending on your specific circumstances, your doctor may want you to:

• stop taking one of the medications,
• change one of the medications to another,
• change how you are taking one or both of the medications, or
• leave everything as is.

An interaction between two medications does not always mean that you must stop taking one of them. Speak to your doctor about how any drug interactions are being managed or should be managed.

Medications other than those listed above may interact with Levitra (Vardenafil). Tell your doctor or prescriber about all prescription, over-the-counter (non-prescription), and herbal medications that you are taking. Also tell them about any supplements you take. Since caffeine, alcohol, Nicotine from cigarettes, and street drugs can affect the action of many medications, you should let your prescriber know if you use them.

Before you begin using a medication, be sure to inform your doctor of any medical conditions or Allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use Levitra (Vardenafil).

Alcohol: Consumption of alcohol in large amounts may decrease the ability to get an erection and may also temporarily decrease blood pressure, causing dizziness and fainting.

Blood pressure: Tell your doctor if you are taking medications to treat high blood pressure, as the combination of these medications with Levitra (Vardenafil) may add to the blood-pressure-lowering effect of these medications. If you have Low Blood Pressure, discuss with your doctor how Levitra (Vardenafil) may affect your medical condition, how your medical condition may affect the dosing and effectiveness of Levitra (Vardenafil), and whether any special monitoring is needed.

Grapefruit juice: Grapefruit juice can increase the amount of Levitra (Vardenafil) in your bloodstream. Do not drink grapefruit juice when taking Levitra (Vardenafil).

Hearing problems: If you experience a sudden decrease or loss of hearing you should seek medical attention immediately.

Heart conditions: Men who have or have had heart disease or a heart attack or stroke should speak to their doctor before taking any medication for erectile dysfunction. If chest pains, dizziness, or nausea are experienced during sex, the exertion should be stopped and your doctor informed.

Liver function: Liver disease or reduced liver function may cause Levitra (Vardenafil) to build up in the body, causing side effects. If you have liver problems, discuss with your doctor how Levitra (Vardenafil) may affect your medical condition, how your medical condition may affect the dosing and effectiveness of Levitra (Vardenafil), and whether any special monitoring is needed. Lower doses of Levitra (Vardenafil) may be necessary.

Nitrate-containing medications: Levitra (Vardenafil) should never be taken with any medications that contain nitrates. Blood pressure may drop to life-threatening levels if Levitra (Vardenafil) is taken with any nitrate-containing medication (e.g., nitroglycerin tablets, spray, or patches) or any other nitrates (e.g., isosorbide dinitrate or amyl nitrite "poppers").

Dizziness, fainting spells, heart attack, or stroke may be experienced. If use of a nitrate-containing medication is considered medically necessary, a nitrate may only be taken at least 24 hours after the last dose of Levitra (Vardenafil), and only under close medical supervision.

Penis deformation: As with other medications for erectile dysfunction, if you have an anatomical deformation of the penis such as angulation, cavernosal fibrosis, or Peyronie's disease, you should be closely monitored by your doctors if you take Levitra (Vardenafil).

Prolonged erection: If an erection lasts longer than 4 hours (a rare occurrence), seek immediate medical assistance. If this condition is not treated quickly, tissue damage and permanent loss of the ability to have an erection could result. Tell your doctor if you have any of the following conditions as they may increase your risk of a prolonged erection: sickle cell Anemia, Multiple Myeloma, or Leukemia.

Prostate problems: Tell your doctor if you are taking medications such as alpha blockers (e.g., Doxazosin) to treat prostate problems, as the combination of these medications with Levitra (Vardenafil) may add to the blood pressure-lowering effect of these medications.

Sexually transmitted infections: Levitra (Vardenafil) does not protect against sexually transmitted infections such as HIV.

Vision problems/eye conditions: If you experience a sudden loss of vision in one or both eyes or other vision-related problems, contact your doctor immediately. Vision loss may be partial or complete. While in some cases the condition may improve over time, the loss can also be permanent.

This rare condition is more likely to occur if you have heart disease, high blood pressure, High Cholesterol, Diabetes, or eye problems, or are over 50 years old or smoke.
