Managing Side Effects of High-Dose Vardenafil

Vardenafil is taken only when needed, about 60 minutes before sexual activity.

Patient characteristics

Tadalafil is structurally different from both sildenafil and vardenafil. Vardenafil's relatively short effective time is comparable to but somewhat longer than sildenafil's. Despite the structural differences between vardenafil and sildenafil, they both show similar ocular side effects due to their similar selectivity overlap with PDE6, an enzyme found in the eye. Beyond its indications for erectile dysfunction, vardenafil may be effective in the treatment of premature ejaculation, where it may significantly increase the time from penetration to ejaculation. The common, adverse drug reactions (side effects) are the same as with other PDE5 inhibitors.

Dosage Forms & Strengths

The frequent vardenafil-specific side-effect is nausea; the infrequent side effects are abdominal pain, back pain, photosensitivity, abnormal vision, eye pain, facial edema, hypotension, palpitation, tachycardia, arthralgia, myalgia, rash, itch, and priapism. One possibly serious, but rare, side effect with vardenafil is heart attack. Also, in rare cases, vardenafil use may cause priapism, a very painful emergency condition that can cause impotence if left untreated. In October 2007, the U.S. Food and Drug Administration (FDA) announced that a warning about possible deafness (sudden hearing loss) would be added to the drug labels of vardenafil, and other PDE5 inhibitors.

What is vardenafil used for?

Vardenafil should not be used by people taking nitrate medications, because combining them with vardenafil might provoke potentially life-threatening hypotension (low blood pressure). Further, vardenafil causes lengthening of the QT interval. Therefore, it should not be taken by people taking other medications that affect the QT interval (such as amiodarone). Vardenafil was co-marketed by Bayer Pharmaceuticals, GlaxoSmithKline, and Schering-Plough under the brand name Levitra. As of 2005, the co-promotion rights of GSK on Levitra have been returned to Bayer in many markets outside the US. The medicine can help achieve an erection when sexual stimulation occurs.
