Makena Side Effects Center

Medical Editor: Melissa Conrad Stöppler, MD

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.

Our Makena (hydroxyprogesterone caproate) Side Effects Drug Center provides a comprehensive view of available drug information on the potential side effects when taking this medication.

This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.

Makena FDA Prescribing Information: Side Effects
(Adverse Reactions)

SIDE EFFECTS

For the most serious adverse reactions to the use of progestins, see WARNINGS AND PRECAUTIONS.

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 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-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).

Common Adverse Reactions

The most common adverse reaction was injection site pain, which was reported after at least one injection by 34.8% of the Makena group and 32.7% of the control group. Table 3 lists adverse reactions that occurred in ≥ 2% of subjects and at a higher rate in the Makena group than in the control group.

In the clinical trial, 2.2% of subjects receiving Makena were reported as discontinuing therapy due to adverse reactions compared to 2.6% of control subjects. The most common adverse reactions that led to discontinuation in both groups were urticaria and injection site pain/swelling (1% each).

Pulmonary embolus in one subject and injection site cellulitis in another subject were reported as serious adverse reactions in Makena-treated subjects.

Postmarketing Experience

The following adverse reactions have been identified during postapproval use of Makena. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.

  • Body as a whole: Local injection site reactions (including erythema, urticaria, rash, irritation, hypersensitivity, warmth); fatigue; fever; hot flashes/flushes
  • Digestive disorders: Vomiting
  • Infections: Urinary tract infection
  • Nervous system disorders: Headache, dizziness
  • Pregnancy, puerperium and perinatal conditions: Cervical incompetence, premature rupture of membranes
  • Reproductive system and breast disorders: Cervical dilation, shortened cervix
  • Respiratory disorders: Dyspnea, chest discomfort
  • Skin: Rash
