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.

  • Do not use Makena in women with any of the following conditions:
    • Current or history of thrombosis or thromboembolic disorders
    • Known or suspected breast cancer, other hormone-sensitive cancer or history of these conditions
    • Undiagnosed abnormal vaginal bleeding unrelated to pregnancy
    • Cholestatic jaundice of pregnancy
    • Liver tumors, benign or malignant, or active liver disease
    • Uncontrolled hypertension
  • Makena should be discontinued if thrombosis or thromboembolism occurs
  • Allergic reactions, including urticaria, pruritus and angioedema, have been reported with use of Makena or with other products containing castor oil
  • Women receiving Makena should be monitored if they:
    • Are prediabetic or diabetic
    • Have conditions that may be affected by fluid retention, such as preeclampsia, epilepsy, cardiac or renal dysfunction
    • Have a history of clinical depression; Makena should be discontinued if depression recurs
    • Develop jaundice; consider whether benefit of use warrants continuation
    • Develop hypertension
  • Certain pregnancy-related fetal and maternal complications or events were numerically increased in Makena-treated subjects as compared to placebo subjects, including miscarriage (2.4% vs. 0%) and stillbirth (2% vs. 1.3%), admission for preterm labor (16% vs. 13.8%), preeclampsia or gestational hypertension (8.8% vs. 4.6%), gestational diabetes (5.6% vs. 4.6%), and oligohydramnios (3.6% vs. 1.3%)
  • In a study where the Makena intramuscular injection was compared with placebo, the most common adverse reactions reported with Makena intramuscular injection (reported incidence in ≥2% of subjects and higher than in the control group) were: injection site reactions (pain [35%], swelling [17%], pruritus [6%], nodule [5%]), urticaria (12%), pruritus (8%), nausea (6%), and diarrhea (2%)
  • In studies where the Makena subcutaneous injection using auto-injector was compared with Makena intramuscular injection, the most common adverse reaction reported with Makena Auto-Injector use (and higher than with Makena intramuscular injection) was injection site pain (10% in one study and 34% in another)

Clinical Guideline

Injectable HPC is recommended by the SMFM to reduce the risk of preterm birth for clinically indicated patients2

SMFM clinical guideline chart

Per the 2017 SMFM statement on choice of progestogen, vaginal progesterone should not be considered a substitute for HPC in at‑risk women.3

Adapted from the SMFM Clinical Guideline published in the May 2012 American Journal of Obstetrics & Gynecology.
Emphasis added to highlight patient identification and initiation, and duration of therapy.

HPC=hydroxyprogesterone caproate; SMFM=Society for Maternal-Fetal Medicine; SPTB=spontaneous preterm birth; TVU=transvaginal ultrasound; CL=cervical length.


In a clinical study, comparable bioavailability was seen between Makena Auto-Injector dosed subcutaneously (1.1 mL; back of upper arm) and Makena dosed IM (1 mL; gluteus maximus).1*
