Levitra (vardenafil) is commonly used to treat erectile dysfunction, a common complaint among men with multiple sclerosis (MS). It belongs in a class of medications called phosphodiesterase (PDE) inhibitors that work by increasing blood flow to the penis during sexual stimulation in order to cause an erection. Though Vardenafil does not cure erectile dysfunction or increase sexual desire, it can be an effective treatment for erectile dysfunction in men with MS.
Vardenafil is prescribed in tablet form. It should be taken with a glass of water about 25 minutes to an hour before sexual activity. Dosages range from 5-20 mg as needed, only once a day. The effects can last around four hours.
Common side effects include headaches, flushing, upset stomach, visual disorders, nasal congestion, and dizziness. Vardenafil should not be taken with medicines containing nitrates and should be used with caution by men with existing heart conditions, liver or kidney function problems, or low blood pressure.
Although the cause of sexual dysfunction is not fully understood it can be attributed to pathological or psychological issues.
Sexual arousal, response, and orgasm require communication between the brain and sexual organs via the spinal cord. Nerve damage related to MS may lead to problems such as hypo-orgasmia or anorgasmia; decreased vaginal secretion and reduced libido in women; and erectile, ejaculatory, or orgasmic dysfunction, and reduced libido in men.
Erectile impotence is the most common complaint among men with MS.
