Levitra.

Levitra (vardenafil) is supposed to be taken by only male patients with erectile dysfunction (male impotence). This drug will not work for females and is therefore not supposed to be taken by them. You will need to make sure you always take Levitra as recommended and avoid sharing it with other people. If you purchased Levitra online, you will have the label of it to read carefully and find out if you have any possible contraindications. Some conditions may affect the dose of Levitra you are prescribed, such as heart disease or heart rhythm problems, stomach ulcer, bleeding disorder, physical deformity of the penis, recent history of a heart attack, kidney disease, blood cell disorder, retinitis pigmentosa, recent history of stroke or blood clots, family history of Long QT syndrome, liver disease, as well as high or low blood pressure. You will have to take Levitra about an hour before having sex. This medicine has been reported to provide you with up to 5 hours of efficiency, although this period may differ for different people. It is therefore recommended that you attempt having sex right after you took your dose of Levitra and it became efficient.
