Misoprostol: Dosage Guidelines, Global Availability, and Clinical Use
Misoprostol is primarily an ulcer medication, but it’s used in conjunction with mifepristone in 98% of all reported medication abortions in the US, according to the Guttmacher Institute. The combination is “the gold standard for medication abortion in the US and elsewhere,” said Alice Mark, interim medical advisor for the National Abortion Federation. Studies show that medication abortion care is safe and effective.
Dosage and Administration in Obstetrics and Gynaecology
This independent site has been set up to distribute dosage guidelines for the use of misoprostol in obstetrics and gynaecology. The correct dosage varies greatly according to gestation, indication and route of administration – using the correct dosage is vital for success and to prevent complications.
Off-Label Use and Indications
Cytotec, the original misoprostol brand, was only approved for the prevention and treatment of gastric ulcers. However, like many drugs, it can be safely used 'off label' for other indications. Plenty of generic misoprostol preparations are available and are labelled for use for reproductive health indications. Regarding the protocol, medication abortion involves taking two different drugs, mifepristone and misoprostol, for use up to the first 70 days (10 weeks) of pregnancy.
