Cialis (tadalafil) is generally used to treat erectile dysfunction as well as the symptoms of benign prostatic hyperplasia, such as urinating difficulties, in adult men.Tadalafil may be effective in treating some men with MS who experience sexual dysfunction, as it works by enhancing blood flow into the penis and increasing erectile response.2   

It is taken by mouth with or without food, as needed, 10 mg prior to anticipated sexual activity and may be increased to 20 mg or decreased to 5 mg according to efficacy. One pill is not to be taken more often than once every 24 hours.3

Tadalafil will not cause an erection without stimulation of the penis.4

Common side effects a person may experience are headache, indigestion, diarrhea, sinus pain, sore throat and/or muscle pain.5

Sexual problems are present in a high proportion of people with MS, although the origin of the problems may be either pathological or psychological. Sexual arousal, response, and orgasm require communication between the brain and sexual organs, via the spinal cord.2 If there is nerve damage related to MS, people may experience problems such as hypo-orgasmia/anorgasmia, decreased vaginal secretion and reduced libido in women, and erectile dysfunction, ejaculatory and/or orgasmic dysfunction, and reduced libido in men. Erectile impotence is the most common complaint in men with MS.6
