Makena (hydroxyprogesterone caproate) is a prescription hormone medicine (progestin) used in women who are pregnant with only one baby and who have delivered a premature baby in the past. Makena is used in these women to help lower the risk of having a preterm baby again. Common side effects of Makena may include blood clots, allergic reactions, fluid retention, hypertension, migraine, depression, and jaundice. Makena is not intended for use to stop active preterm labor.
Administered by a health-care provider, Makena is injected intramuscularly at a weekly dose of 250mg. No drug interaction studies have been conducted with Makena. However, the metabolism of certain drugs such as acetaminophen, methadone, and nicotine may be increased during treatment with Makena.

Clinical Trials Experience
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to the rates in the clinical trials of another drug and may not reflect the rates observed in practice.
In a vehicle (placebo)-controlled clinical trial of 463 pregnant women at risk for spontaneous preterm delivery based on obstetrical history, 310 received 250 mg of Makena (hydroxyprogesterone caproate injection) and 153 received a vehicle formulation containing no drug by a weekly intramuscular injection beginning at 16 to 20 weeks of gestation and continuing until 37 weeks of gestation or delivery, whichever occurred first.1 [See Clinical Studies.]
Certain pregnancy-related fetal and maternal complications or events were numerically increased in the Makena (hydroxyprogesterone caproate injection) -treated subjects as compared to control subjects, including miscarriage and stillbirth, admission for preterm labor, preeclampsia or gestational hypertension, gestational diabetes, and oligohydramnios (Tables 1 and 2).

Control n/N |
| Miscarriage ( < 20 weeks)1 | 5/209 | 0/107 |
| Stillbirth ( ≥ 20 weeks)2 | 6/305 | 2/153 |
