Uses
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
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.

ADVERSE REACTIONS A. Serious arterial thrombotic and venous thromboembolic events, including cases of pulmonary emboli (some fatal), deep vein thrombosis, myocardial infarction, and strokes, have been reported in women using progestins.
