Hydroxyprogesterone Caproate injection is indicated to reduce the risk of preterm birth in women pregnant with a single baby (singleton gestation) who have a documented history of at least one prior spontaneous preterm birth. Its use is limited to this specific obstetric risk-reduction setting and must be initiated and supervised by a qualified physician.
Regulatory note: The approval of the branded intramuscular product for this indication was originally granted under an accelerated-approval pathway. A required confirmatory trial did not verify the expected clinical benefit, and regulatory status of branded Hydroxyprogesterone Caproate products has been reconsidered in some markets, including voluntary market withdrawal of the branded U.S. injection in 2023. Where still available, Hydroxyprogesterone Caproate should be used only under specialist obstetric guidance, and patients should discuss current local approval status and evidence with their physician.
Hydroxyprogesterone Caproate has historically also been used, less commonly and with weaker evidence, for other progestin-responsive gynecological indications. Such uses are not well-established by current major guidelines and should be considered only on individualized specialist advice; Hydroxyprogesterone Caproate is not indicated for general use during pregnancy outside the specific preterm-birth-risk-reduction population described above.
| Population | Dose | Schedule |
|---|---|---|
| Pregnant women, singleton gestation, prior spontaneous preterm birth | 250 mg (1 mL) by intramuscular injection | Once weekly, starting between 16 weeks 0 days and 20 weeks 6 days of gestation, and continuing weekly until 37 weeks 0 days of gestation or delivery, whichever occurs first |
If a scheduled dose is missed, the next dose should be administered as soon as possible, per physician instruction; a missed-dose window of more than 7 days should be discussed with the treating obstetrician before resuming.
Hydroxyprogesterone Caproate must be initiated and monitored by an obstetric specialist; it is not intended for self-initiation or use outside this specific clinical protocol. See Contraindications and Precautions and Warnings before use.
Patients should seek prompt medical attention for signs of a blood clot (leg pain/swelling, chest pain, shortness of breath), severe allergic reaction, or new/worsening mood changes while receiving Hydroxyprogesterone Caproate.
Hydroxyprogesterone Caproate is contraindicated in patients with any of the following:
