A to Z of MS Vardenafil hydrochloride
Product name
Levitra
Vardenafil is a prescription medicine for the treatment of erectile dysfunction in men.
How vardenafil works
Erectile dysfuntion is the inability to achieve or maintain an erection sufficient for satisfactory sexual performance. In multiple sclerosis this is commonly associated with bladder problems and both disorders are believed to be as a direct result of damage to the nerves in the spinal cord.
Whilst psychologically driven erections are likely to have been impaired by MS, reflex responses remain intact. Vardenafil works by delaying the action of enzymes called phosphodiesterases. This results in relaxing the blood vessels and allowing blood to flow into the penis on sexual stimulation.
How vardenafil is given
Vardenafil is taken orally between 25 minutes and one hour before sexual activity is planned. Dose ranges from 5-20mg as necessary; maximum dose frequency is once a day.
Side effects and contraindications
Prior to starting treatment the cardiovascular status of the individual should be assessed, as there is a degree of cardiac risk associated with sexual activity. Vardenafil can cause the blood pressure to drop suddenly if taken with certain other medications. A sudden drop in blood pressure can cause dizziness or fainting.
The most common side effects include headache, flushing, rhinitis (stuffy or runny nose), indigestion, upset stomach, or dizziness. The only absolute contraindication to vardenafil is concurrent nitrate therapy.
