Levitra 10 mg is available at the best price; it does not cure erectile dysfunction or increase sexual desire. This medicine does not prevent pregnancy or the spread of sexually transmitted diseases such as human immunodeficiency virus (HIV). It is used to treat adult men (aged 18 years or over) with erectile dysfunction (sometimes called impotence), when they cannot get or keep a hard penis (erection) sufficient for satisfactory sexual activity. For Levitra to be effective, sexual stimulation is required.
