Miscarriage - threatened - Treatment

Alternative Names

Threatened miscarriage; Threatened spontaneous abortion; Abortion - threatened; Threatened abortion

Treatment:

You may be told to avoid or restrict some forms of activity. Not having sexual intercourse is usually recommended until the warning signs have disappeared.

The use of progesterone is controversial. It might relax smooth muscles, including the muscles of the uterus. However, it also might increase the risk of an incomplete abortion or an abnormal pregnancy. Unless there is a luteal phase defect, progesterone should not be used.

Expectations (prognosis):

Many women with threatened miscarriage go on to have a normal pregnancy.

Complications:

Anemia
Infection
Miscarriage
Moderate-to-heavy blood loss

Calling your health care provider:

If you know you are (or are likely to be) pregnant and you have any symptoms of threatened miscarriage, contact your prenatal health care provider immediately.
