What is Levitra?
- Levitra (vardenafil) is a phosphodiesterase inhibitor. It works by helping to relax muscles and increase blood flow into the penis during sexual stimulation. This helps men to achieve and maintain an erection.
- Levitra is used to treat erectile dysfunction (impotence).
Before taking Levitra
Some medicines are not suitable for people with certain conditions, and sometimes a medicine may only be used if extra care is taken. For these reasons, before you start taking Levitra it is important that your doctor or pharmacist knows:
- If you have any disease, injury or deformity of your penis.
- If you have heart or blood vessel disease.
- If you have a condition which causes bleeding, such as a stomach ulcer.
- If you have had an eye condition causing loss of vision.
- If you have low blood pressure or angina.
- If you have liver or kidney problems.
- If you have had a stroke or a heart attack.
- If you have sickle cell disease.
- If you have ever had bone marrow cancer or leukaemia.
- If you are taking or using any other medicines. This includes any medicines you are taking which are available to buy without a prescription, such as herbal and complementary medicines. It is important that your doctor knows if you are using a medicine prescribed for angina pain, or if you are using a 'nitrite' drug (such as in the recreational drug known as 'poppers').
- If you have ever had an allergic reaction to this or to any other medicine.
How should I take Levitra?
- Take Levitra exactly as prescribed by your doctor. Do not take in larger or smaller amounts or for longer than recommended. Follow the directions on your prescription label.
- Levitra can be taken with or without food.
- Levitra is usually taken only when needed, about 60 minutes before sexual activity. The medication can help achieve an erection when sexual stimulation occurs. An erection will not occur just by taking a pill. Follow your doctor's instructions.
- Do not take Levitra more than once a day. Allow 24 hours to pass between doses. Contact your doctor or seek emergency medical attention if your erection is painful or lasts longer than 4 hours. A prolonged erection (priapism) can damage the penis. Store at room temperature away from moisture and heat.
What should I avoid while taking Levitra?
- Drinking alcohol can increase certain side effects of Levitra.
- Grapefruit and grapefruit juice may interact with Levitra and lead to potentially dangerous effects. Discuss the use of grapefruit products with your doctor.
- Do not use any other drug to treat impotence, such as alprostadil or yohimbine, unless your doctor tells you to.
