By body system

Gastrointestinal side effects

Gastrointestinal side effects, including diarrhea (up to 40%), abdominal pain (up to 20%), nausea (3.2%), flatulence, and dyspepsia, are commonly associated with misoprostol therapy.

Gastrointestinal side effects, especially diarrhea, are dose-related and typically transient. However, profound diarrhea has led to severe dehydration in rare cases. Diarrhea may be aggravated by magnesium-containing antacids.

While administration with meals helps to minimize gastrointestinal side effects, dosage reductions may be necessary in some patients who develop severe diarrhea.

Genitourinary side effects

Postmenopausal bleeding may occur in patients treated with misoprostol. It is recommended that patients who develop postmenopausal bleeding undergo gynecological evaluation to rule out non-drug related pathology.

A 25-year-old female developed stress urinary incontinence after one month of misoprostol therapy. The patient was rechallenged with misoprostol with symptoms recurring after 7 days of therapy. Urodynamic studies revealed a deficiency in urethral resistance while on misoprostol.

Genitourinary side effects occur in up to 3.3% of female patients and include spotting, cramps, hypermenorrhea, dysmenorrhea, and postmenopausal vaginal bleeding. In addition, urinary incontinence has been reported.

Nervous system side effects

Nervous system side effects of misoprostol are rare, but include headache, dizziness, and neuropathy. Lethargy and delusions have been described with concomitant use of misoprostol and phenylbutazone or naproxen.
