Progesterone suppositories contain the hormone progesterone and work by altering the lining of the uterus. They are available by prescription and are typically used as part of an assisted reproductive technology program, according to Drugs.com. The product may also be used to facilitate embryo implantation and early pregnancy in some women. The suppository is typically placed into the vagina with an applicator and is used two to three times a day for a prescribed period of time, up to 70 days. Like all drugs, progesterone suppositories carry the risk of adverse effects.
Vomiting is a common side effect of progesterone suppositories, along with nausea and stomach pain. It is also common to feel bloated and experience abdominal distention. Some women become constipated while using this product.
The use of progesterone inserts can lead to excessive tiredness or drowsiness. It is also possible to feel moody or irritable while using this hormone.
Some patients experience mild vaginal bleeding and pelvic cramping. It is possible to experience vaginal burning or irritation while using progesterone suppositories. Breast tenderness and headache are common complaints.

Rarely, a patient experiences cerebrovascular changes such as weakness in an arm or leg, paralysis or dropping of one side of the face, difficulty speaking or difficulty understanding words.
