Makena is a progestin indicated to reduce the risk of preterm birth in women with a singleton pregnancy who have a history of singleton spontaneous preterm birth. The effectiveness of Makena is based on improvement in the proportion of women who delivered <37 weeks of gestation. There are no controlled trials demonstrating a direct clinical benefit, such as improvement in neonatal mortality and morbidity.

Limitation of use: While there are many risk factors for preterm birth, safety and efficacy of Makena has been demonstrated only in women with a prior spontaneous singleton preterm birth. It is not intended for use in women with multiple gestations or other risk factors for preterm birth.

Makena should not be used in women with any of the following conditions: blood clots or other blood clotting problems, breast cancer or other hormone-sensitive cancers, or history of these conditions; unusual vaginal bleeding not related to your current pregnancy, yellowing of the skin due to liver problems during pregnancy, liver problems, including liver tumors, or uncontrolled high blood pressure.

Before you receive Makena, tell your healthcare provider if you have an allergy to hydroxyprogesterone caproate, castor oil, or any of the other ingredients in Makena; diabetes or prediabetes, epilepsy, migraine headaches, asthma, heart problems, kidney problems, depression, or high blood pressure.

In a clinical study, certain complications or events associated with pregnancy occurred more often in women who received Makena. These included miscarriage (pregnancy loss before 20 weeks of pregnancy), stillbirth (fetal death occurring during or after the 20th week of pregnancy), hospital admission for preterm labor, preeclampsia (high blood pressure and too much protein in your urine), gestational hypertension (high blood pressure caused by pregnancy), gestational diabetes, and oligohydramnios (low amniotic fluid levels).

Makena may cause serious side effects including blood clots, allergic reactions, depression, and yellowing of your skin and the whites of your eyes. The most common side effects of Makena include injection site reactions (pain, swelling, itching, bruising, or a hard bump), hives, itching, nausea, and diarrhea.

You may report an adverse event related to AMAG Pharmaceuticals' products by calling 1-877-411-2510 or emailing amag@druginfo.com. If you prefer, you may contact the U.S. Food and Drug Administration (FDA) directly at fda.gov/medwatch or call 1-800-FDA-1088.

Understanding Preterm Birth

What is preterm birth?

In the United States, approximately 1 in 10 babies is born prematurely each year.

But how early is too early?

The goal of a healthy pregnancy is to deliver full term (39 to 40 weeks) to give your baby the time needed to grow and develop.2 For example, your baby’s brain and lungs are still developing during the last weeks of pregnancy.1

Preterm birth is when a baby arrives too early; that’s before 37 weeks of pregnancy, or 3 weeks prior to the baby’s due date.3 Preterm birth can be unexpected or unplanned. Sometimes, a baby needs to be delivered earlier than normal in certain medical situations.4

Preterm birth can happen to any pregnant woman and, in most cases, healthcare providers don’t fully understand what actually causes preterm birth. But moms who have delivered a baby too early (before 37 weeks)—regardless of the number of weeks early they’ve delivered—in the past are at a higher risk for having another preterm birth.5,6

While there are many causes for preterm birth, the safety and benefits of Makena have been demonstrated only in women who’ve unexpectedly delivered their baby prior to 37 weeks of pregnancy. It’s not meant for use in women with multiple gestations or other risk factors for preterm birth.
