Indications and Usage
Hydroxyprogesterone Caproate Injection, USP is indicated in non-pregnant women: for the treatment of advanced adenocarcinoma of the uterine corpus (Stage III or IV); in the management of amenorrhea (primary and secondary) and abnormal uterine bleeding due to hormonal imbalance in the absence of organic pathology, such as submucous fibroids or uterine cancer; as a test for endogenous estrogen production and for the production of secretory endometrium and desquamation.
Dosage and Administration
Suggested dosages are presented in the therapy guide. Because of the low viscosity of the vehicle, Hydroxyprogesterone Caproate Injection, USP may be administered with a small gauge needle. Care should be taken to inject the preparation deeply into the upper outer quadrant of the gluteal muscle following the usual precautions for intramuscular injection. Since the 250 mg potency provides a high concentration in a small volume, particular care should be observed to administer the full dose. Note: Use of a wet needle or syringe may cause the solution to become cloudy; however, this does not affect the potency of the material. Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit. Protect from light. Store vial in its box. Store upright. Discard any unused product within 5 weeks after first use.

Hydroxyprogesterone caproate is contraindicated in patients with known or suspected carcinoma of the breast, other hormone-sensitive cancer, or history of these conditions; undiagnosed abnormal vaginal bleeding; liver dysfunction or disease; missed abortion, and in those with a history of hypersensitivity to the drug.
