Do progestin-only pills have any side effects?

Donna Hill Howes, RN
Family Practitioner

Side effects may include headaches, depression, weight gain, swelling, breast tenderness, nausea, irregular periods, breakthrough bleeding, spotting, and missed periods. Up to 10% of pregnancies in women who take progestin-only pills are ectopic pregnancies. This is when the pregnancy develops outside the uterus, often in a fallopian tube.

Progestin-only pills are more effective at preventing pregnancy in the uterus (normal pregnancy) than in the fallopian tubes (ectopic pregnancy). This is why ectopic pregnancies are more common in women who use progestin-only pills than in women who use other types of progestin-only birth control, such as medroxyprogesterone acetate shots.
