Levitra
Generic name: Vardenafil
Brand names: Levitra
Levitra is an oral drug for male impotence, also known as erectile dysfunction (ED).
Levitra is a phosphodiesterase inhibitor. It works by helping to increase blood flow into the penis during sexual stimulation. This helps you to achieve and maintain an erection.
Levitra causes erections only during sexual excitement. It does not work in the absence of arousal and does not increase sexual desire.
Take one Levitra tablet about one hour before sexual activity, with or without food.
Take Levitra only before sexual activity, but no more than once a day. Do not take two doses at once.
Store Levitra at room temperature.
Do not take Levitra if you are also using a nitrate drug for chest pain or heart problems. Levitra with a nitrate medicine can cause a serious decrease in blood pressure, leading to fainting, stroke, or heart attack.
Levitra can decrease blood flow to the optic nerve of the eye, causing sudden vision loss. This has occurred in a small number of people taking Levitra, most of whom also had heart disease, diabetes, high blood pressure, high cholesterol, or certain pre-existing eye problems, and in those who smoke or are over 50 years old. It is not clear whether Levitra is the actual cause of vision loss.
Stop using Levitra and get emergency medical help if you have sudden vision loss.
Before taking Levitra, tell your doctor if you are allergic to any drugs, or you have:
- heart disease or heart rhythm problems;
- a recent history (in the past 6 months) of a heart attack, angina (chest pain), or congestive heart failure;
- a recent history of stroke or blood clots;
- a personal or family history of “Long QT syndrome”;
- high or low blood pressure;
- liver disease;
- kidney disease (or if you are on dialysis);
- a blood cell disorder such as sickle cell anemia, multiple myeloma, or leukemia;
- a bleeding disorder such as hemophilia;
- a stomach ulcer;
- retinitis pigmentosa (an inherited condition of the eye);
- a physical deformity of the penis (such as Peyronie’s disease); or
- if you have been told you should not have sexual intercourse for health reasons.
If you have any of these conditions, you may need a dose adjustment or special tests to safely take Levitra.
Seek emergency medical attention if you think you have used too much of Levitra. Overdose symptoms may include back pain, muscle pain, or vision problems.
Avoid drinking alcohol, which can increase some of the side effects of Levitra.
Grapefruit and grapefruit juice may interact with Levitra. Discuss the use of grapefruit products with your doctor. Do not increase or decrease the amount of grapefruit products in your diet without first talking to your doctor.
Do not use any other drug to treat impotence, such as alprostadil (Caverject, Muse, Edex) or yohimbine (Yocon, Yodoxin, others), unless your doctor tells you to.
Stop using Levitra and call your doctor at once if you have any of these serious side effects:
- sudden vision loss;
- ringing in your ears, or sudden hearing loss;
- chest pain or heavy feeling, pain spreading to the arm or shoulder, nausea, sweating, general ill feeling;
- irregular heartbeat;
- swelling in your hands, ankles, or feet;
- shortness of breath;
- vision changes;
- feeling light-headed, fainting; or
- penis erection that is painful or lasts 4 hours or longer.
Less serious side effects may include:
- warmth or redness in your face, neck, or chest;
- stuffy nose;
- headache;
- upset stomach; or
- back pain.
This is not a complete list of side effects and others may occur. Tell your doctor about any unusual or bothersome side effect.
