Before You Begin Taking Levitra

Tell your doctor if you:

• have any allergies to vardenafil or any other ingredients in levitra tablets, or to any other medicines that you have used in the past, or to any other substances such as food, preservatives or dyes
• have any heart or blood vessel problems
• have ever suffered a heart attack or stroke
• have any kidney or liver problems
• have leukaemia (cancer of the blood cells)
• have multiple myeloma (a cancer of the bone marrow)
• have any disease or deformity of your penis
• have low blood pressure
• have sickle cell anaemia
• have stomach ulcers
• have a serious eye condition called retinitis pigmentosa
• are receiving any other treatment for impotence

If you have not told your doctor or pharmacist about any of the above, tell them before you start taking levitra. Taking other medicines. Do not take levitra if you are using nitrate or nitric oxide donor medicines for angina.

Tell your doctor or pharmacist if you are taking any other medicines, including those that you buy without a prescription from your pharmacy, supermarket or health food shop.

Some medicines may be affected by levitra or vice versa. These medicines include:

• ketoconazole and itraconazole, used to treat fungal infections
• erythromycin, an antibiotic
• ritonavir and indinavir and other protease inhibitors used for the treatment of HIV infection
• alpha-blockers, medicines used to treat an enlarged prostate (BPH) or high blood pressure.(Examples of alpha-blockers areterazosin, tamsulosin and prazosin.)

You may need to use different amounts of your medicine, or you may need to take different medicines. Your doctor will be able to advise you. Your doctor or pharmacist will also have a more complete list of medicines to be careful with or avoid while taking levitra.

Ask your doctor or pharmacist, if you are not sure if you are taking any of these medicines.
