Levitra (generic name, vardenafil) is a prescription drug that is used to treat erectile dysfunction (ED) - which is an inability in men to achieve penile erection. This embarrassing situation of failing to maintain an erection until ejaculation is often referred to as impotence. Whatever its underlying physiological and psychological causes are, this condition was once a taboo subject. Thanks to recent heavy advertisements on drugs in this category, and much publicity of high-interest stories, taking remedial medications such as Levitra has become a more accepted norm.

Levitra is an FDA-approved oral medication that is available only by prescription. It works by relaxing your muscles to increase blood flow to the penis. The extra flow of blood will engorge the penis thus helping men get a harder erection. Moreover, Levitra works by preventing blood from flowing out of the penis. This helps you keep a longer-lasting erection. Generally, after the sexual activity ceases, the erection will go away. If the penis persists in staying erect for more than 4 hours, seek medical attention to avoid long-term injury.

Certain other medications can work to inhibit the elimination of enzymes that are stimulated by Levitra. People who are on medications such as erythromycin, ketoconazole (Nizoral), itraconazole (Sporanox), indinavir (Crixivan) and ritonavir (Norvir) are recommended to take lower dosages of Levitra. In addition, the time between each dosage may need to be extended. Normally a minimal initial dosage of 10 mg per day is recommended.

Common Levitra adverse drug reactions include nausea. Infrequent ADRs include abdominal pain, back pain, photosensitivity, abnormal vision, eye pain, facial oedema, hypertension, palpitation, tachycardia, arthralgia, myalgia, rash, itch, and priapism. (Rossi, 2004). The side effects reported in clinical trials include headache, flushing and stuffy or runny nose. In extremely rare cases, report to doctor immediately, if you have a sudden decrease or loss of vision, in one or both eyes.

However, what is special about Levitra is that people with high blood pressure, high cholesterol levels, and even diabetics, have been found to be safely taking this medication. These health factors don't seem to impede these men from enjoying increased sexual activities after taking it. As with taking any new medications, it is always best to ask your doctor about drug interactions with your existing medications, and with your present medical conditions.

So before taking Levitra, talk to your doctor if you have or have had a history of heart disease such as irregular heart rhythms or angina, or congestive heart failure, or heart attacks. Make your doctor aware of any history of stroke, blood clots, blood pressure problems, kidney disease, liver disease, blood cell disorder, bleeding disorder, stomach ulcers, retinitis pigmentosa, penis deformity, or if, for health reasons, you cannot engage in sexual intercourse.

If any of those conditions apply to you, your physician may choose one of three options. First, he or she may decide to seek an alternative to Levitra all together. He or she may also reduce the regular dosage for your case, or continually observe and test your health during treatment.
