For the most serious adverse reactions to the use of progestins, see Warnings and Precautions.

Postmarketing Experience
The following adverse reactions have been identified during post approval use of hydroxyprogesterone caproate injection. 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

USE IN SPECIFIC POPULATIONS
Pregnancy Risk Summary:
Data from the placebo-controlled clinical trial and the infant follow-up safety study did not show a difference in adverse developmental outcomes between children of hydroxyprogesterone caproate injection-treated women and children of control subjects. However, these data are insufficient to determine a drug-associated risk of adverse developmental outcomes as none of the hydroxyprogesterone caproate injection-treated women received the drug during the first trimester of pregnancy.

Lactation Risk Summary: Low levels of progestins are present in human milk with the use of progestin containing products, including hydroxyprogesterone caproate. Published studies have reported no adverse effects of progestins on the breastfed child or on milk production.

Pediatric Use: Hydroxyprogesterone caproate injection is not indicated for use in women under 16 years of age.

Hepatic Impairment: Hydroxyprogesterone caproate injection is extensively metabolized and hepatic impairment may reduce the elimination of hydroxyprogesterone caproate injection.

OVERDOSAGE
In the case of overdosage, the patient should be treated symptomatically.
