Description
Hydroxyprogesterone is a form of progestin, a manmade form of a female hormone called progesterone.
Hydroxyprogesterone is used to lower the risk of premature birth in a woman who has already had one premature baby. Hydroxyprogesterone will not stop premature labor that has already begun.
Hydroxyprogesterone is not for use in women who are pregnant with more than one baby (twins, triplets, etc).
Dosage form
Oil, Intramuscular
Pharmacologic Category
Progestin
Pharmacology
Hydroxyprogesterone is a synthetic progestin. The mechanism by which hydroxyprogesterone reduces the risk of recurrent preterm birth is not known. Hydroxyprogesterone caproate may induce regressive changes in uterine adenocarcinoma.
Distribution
Extensively bound to plasma proteins including albumin and corticosteroid-binding globulins
Metabolism
Hepatic via CYP3A4 and 3A5; forms metabolites
Excretion
Urine (~30%) and feces (~50%); primarily as metabolites
Time to Peak
Serum: IM: Nonpregnant females: 3 to 7 days; Pregnant females (singleton pregnancies): 1 to 7 days
Half-Life Elimination
Nonpregnant females: ~8 days; Pregnant females (singleton pregnancies): 16.4 ± 3.6 days
Contraindications
Hypersensitivity to hydroxyprogesterone caproate or any component of the formulation; current or history of thrombosis or thromboembolic disorders; breast cancer or other hormone-sensitive cancer (known, suspected, or history of); undiagnosed abnormal vaginal bleeding unrelated to pregnancy; cholestatic jaundice of pregnancy; liver tumors (benign or malignant) or active liver disease; missed abortion; uncontrolled hypertension; as a diagnostic test for pregnancy.
Documentation of allergenic cross-reactivity for progestins is limited. However, because of similarities in chemical structure and/or pharmacologic actions, the possibility of cross-sensitivity cannot be ruled out with certainty.
Dosing:
Adult
Pregnancy indications: Preterm birth (Makena): Pregnant females ≥16 years of age: Note: Treatment may begin between 16 weeks 0 days and 20 weeks 6 days of gestation. Continue weekly administration until 37 weeks (through 36 weeks, 6 days) gestation or until delivery, whichever comes first.
IM (vial): 250 mg once weekly (every 7 days).

Avoid combination
Warnings/Precautions
Concerns related to adverse events:
- Hypersensitivity: Hypersensitivity and allergic-like reactions (eg, urticaria, pruritus, angioedema) have been reported. Consider discontinuing if allergic reactions occur.
- Retinal vascular thrombosis: May cause retinal vascular thrombosis; discontinue pending examination if migraine, loss of vision, proptosis, diplopia, or other visual disturbances occur; discontinue permanently if papilledema or retinal vascular lesions are observed on examination.
- Thromboembolism: Discontinue if arterial thrombosis, DVT, or thromboembolic events occur. Use is contraindicated with current or history of thrombosis or thromboembolic disorders.
Disease related concerns:
- Carbohydrate intolerance: May have adverse effects on glucose tolerance; use caution in women with prediabetes and diabetes.
- Depression: Use with caution in patients with depression; discontinue if depression occurs.
- Diseases exacerbated by fluid retention: Use with caution in patients with diseases that may be exacerbated by fluid retention, including asthma, epilepsy, preeclampsia, cardiac or renal dysfunction.
- Hepatic impairment: Specific studies have not been conducted; elimination may be decreased. Use is contraindicated with hepatic impairment.
- Hypertension: Monitor women who develop hypertension during therapy; consider risk versus benefit of continuation. Use is contraindicated with uncontrolled hypertension.
- Jaundice: Monitor women who develop jaundice during therapy; consider risk versus benefit of continuation. Use is contraindicated in women with cholestatic jaundice of pregnancy.
Concurrent drug therapy issues:
- Drug-drug interactions: Potentially significant interactions may exist, requiring dose or frequency adjustment, additional monitoring, and/or selection of alternative therapy. Consult drug interactions database for more detailed information.
Dosage form specific issues:
- Benzyl alcohol and derivatives: Some dosage forms may contain benzyl alcohol; large amounts of benzyl alcohol (≥99 mg/kg/day) have been associated with a potentially fatal toxicity (“gasping syndrome”) in neonates; the “gasping syndrome” consists of metabolic acidosis, respiratory distress, gasping respirations, CNS dysfunction (including convulsions, intracranial hemorrhage), hypotension, and cardiovascular collapse (AAP [“Inactive” 1997]; CDC 1982); some data suggest that benzoate displaces bilirubin from protein binding sites (Ahlfors 2001); avoid or use dosage forms containing benzyl alcohol with caution in neonates. See manufacturer’s labeling.
- Castor oil: Some formulations contain castor oil. Discontinue if allergic reactions (eg urticaria, pruritus, angioedema) occur.
Other warnings/precautions:
- Appropriate use: Preterm birth: The effectiveness of hydroxyprogesterone is based on improvement in the proportion of women who delivered at less than 37 weeks of gestation. Clinical benefits related to improved neonatal mortality or morbidity following maternal use have not been demonstrated. Not intended to stop active preterm labor.
- Appropriate use: Uterine adenocarcinoma: While the intramuscular solution is approved for the treatment of stage III or IV adenocarcinoma of the uterine corpus, chemotherapy may be preferable to progestin therapy in the management of advanced disease. Based on a systematic review, response to hormonal therapy is inversely proportional to tumor grade.
- Laboratory changes: Use may change the results of some laboratory tests (eg, coagulation factors, tests of hepatic or thyroid function).
- Product selection: Hydroxyprogesterone caproate is available in multiple dosage forms. The Makena brand and the generic product (generic for Delautin) have different indications (Makena pregnancy indications; the generic product has non-pregnancy indications); products are not interchangeable.
Monitoring Parameters
Glucose (in patients with prediabetes or diabetes); blood pressure; signs/symptoms of depression, fluid retention, jaundice, and/or thromboembolic disorders.
Non-pregnancy uses: Papanicolaou smear, pelvic organ and breast exam prior to therapy
Pregnancy Considerations
Adverse events were not observed in human studies following second or third trimester exposure; use not studied during first trimester.
Following use of Makena, maternal serum concentrations of hydroxyprogesterone caproate are widely variable and may be decreased in women with increased BMI. Hydroxyprogesterone is metabolized by the placenta and reaches the fetal circulation. In one study, the cord:maternal concentration ratio averaged 0.2. Hydroxyprogesterone caproate was detected in cord blood when delivery occurred ≥44 days after the last injection.
Patient Education
- Discuss specific use of drug and side effects with patient as it relates to treatment. (HCAHPS: During this hospital stay, were you given any medicine that you had not taken before? Before giving you any new medicine, how often did hospital staff tell you what the medicine was for? How often did hospital staff describe possible side effects in a way you could understand?)
- Patient may experience injection site pain, nausea, vomiting, diarrhea, abdominal cramps, bloating, breast soreness, weight gain, weight loss, hair loss, decreased sex drive, increased sex drive, lack of appetite, increased appetite, loss of strength and energy, or back pain. Have patient report immediately to prescriber signs of high blood sugar (confusion, fatigue, increased thirst, increased hunger, passing a lot of urine, flushing, fast breathing, or breath that smells like fruit); signs of blood clots (numbness or weakness on one side of the body; pain, redness, tenderness, warmth, or swelling in the arms or legs; change in color of an arm or leg; chest pain; shortness of breath; fast heartbeat; or coughing up blood); vision changes; severe headache; severe dizziness; passing out; depression; shortness of breath; excessive weight gain; swelling of arms or legs; no menstrual periods; severe injection site edema, oozing of blood, or irritation; signs of virilization (in females a deep voice, facial hair, acne, or menstrual changes); abnormal vaginal bleeding; or yellow skin (HCAHPS).
- Educate patient about signs of a significant reaction (eg, wheezing; chest tightness; fever; itching; bad cough; blue skin color; seizures; or swelling of face, lips, tongue, or throat).
Note: This is not a comprehensive list of all side effects. Patient should consult prescriber for additional questions.
Intended Use and Disclaimer: Should not be printed and given to patients. This information is intended to serve as a concise initial reference for health care professionals to use when discussing medications with a patient.
