Off-label use of misoprostol linked to abortion deaths
What Is Misoprostol?
Misoprostol is the generic form of the brand-name drug Cytotec, which is used to prevent ulcers in people who take certain arthritis or pain medicines.
Drugs that can cause stomach damage include aspirin, ibuprofen (Advil, Motrin), naproxen (Aleve, Anaprox, Naprosen), celecoxib (Celebrex), diclofenac (Voltarin, Cataflam), indomethacin (Indocin), and meloxicam (Mobic).
Misoprostol is a synthetic prostaglandin. It works by protecting the stomach lining and decreasing stomach acid secretion.
The Food and Drug Administration (FDA) approved the medication in 1988. The drug was originally manufactured by G.D. Searle & Company, and generic forms of misoprostol are now made by several drug manufacturers.
Misoprostol and Abortion
Misoprostol is sometimes used off-label to end an early pregnancy. (Off-label use means that the FDA has not approved the drug for this purpose.)
The drug is most effective when it's used in combination with methotrexate or mifepristone. Misoprostol can be given orally, buccally (dissolved between the gums and cheek), or vaginally for this purpose.
The FDA has reported that a few women have died from severe infection after having an abortion using mifepristone and vaginal misoprostol.
You should call your doctor immediately if you experience any signs of infection, which may include weakness, pain, muscle aches, nausea, and diarrhea. This rare infection may not cause a fever.
Misoprostol is also sometimes used off-label to induce labor or decrease blood loss after delivery of a baby. However, the FDA has issued an alert about the potential dangers of using misoprostol for these purposes. The risks include a torn uterus, the need for a hysterectomy, and death of the mother and baby.
Pregnancy and Misoprostol
Misoprostolis a Pregnancy Category X drug, which means it is likely to harm an unborn baby, causing birth defects and premature birth. The drug can also harm the pregnant woman, causing uterine rupture, uterine bleeding, miscarriage, or an incomplete miscarriage. You should use an effective form of birth control while taking misoprostol and for at least one month after you stop using it.
Women shouldn't take their first dose of misoprostol until the second or third day of their menstrual period to ensure that they aren't pregnant.
It's not known whether this drug passes into breast milk or if it could harm a breastfeeding baby. You should talk to your doctor about these risks.
Before taking misoprostol, you should tell your doctor if you have:
- Inflammatory bowel disease (IBD)
- Irritable bowel syndrome (IBS)
- Any other intestinal problems
- Heart disease
You should also alert your physician if you suspect you are dehydrated before taking this medicine.
This drug must be taken regularly for you to benefit. Don't stop taking misoprostol without first talking to your doctor.
Call your doctor if you experience severe nausea, stomach pain, or diarrhea lasting several days while on misoprostol.
