Pregnant mice dosed with triamcinolone acetonide via intramuscular or subcutaneous injection at doses equivalent to 0.8 times the MRHD or higher during organogenesis caused cleft palate and a higher rate of resorption. In pregnant rats dosed with triamcinolone acetonide via intramuscular or subcutaneous injection at doses equivalent to 0.3 times the MRHD or higher during organogenesis caused developmental abnormality (cleft palate, omphalocele, late resorption, and growth retardation) and fetal mortality. No notable maternal toxicity was observed in rodents. 

Pregnant rabbits dosed with triamcinolone acetonide via intramuscular injection for 4 days during organogenesis at doses equivalent to 0.15 times the MRHD or higher caused resorption and cleft palate. No notable maternal toxicity was observed. 

Pregnant primates dosed with triamcinolone acetonide via intramuscular injection for 4 days during organogenesis at doses equivalent to 3 times the MRHD or higher caused severe craniofacial CNS and skeletal/visceral malformation and higher prenatal death. No notable maternal toxicity was observed. 

No peri- and post-natal development studies of triamcinolone acetonide in animals have been conducted. 

8.2 Lactation 

Risk Summary 

There are no available data on the presence of triamcinolone acetonide in either human or animal milk, the effects on the breastfed infant, or the effects on milk production. However, corticosteroids have been detected in human milk and may suppress milk production. It is not known whether intra-articular administration of ZILRETTA could result in sufficient systemic absorption to produce detectable quantities in human milk. The developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for ZILRETTA and any potential adverse effects on the breastfed infant from ZILRETTA or from the underlying maternal condition. 

8.3 Females and Males of Reproductive Potential 

Corticosteroids may result in menstrual pattern irregularities such as deviations in timing and duration of menses and an increased or decreased loss of blood. 

8.4 Pediatric Use 

The safety and effectiveness of ZILRETTA in pediatric patients have not been established. 

The adverse effects of corticosteroids in pediatric patients are similar to those in adults. Carefully observe pediatric patients, including weight, height, linear growth, blood pressure, intraocular pressure, and clinical eva luation for the presence of infection, psychosocial disturbances, thromboembolism, peptic ulcers, cataracts, and osteoporosis. Weigh potential growth effects of treatment against clinical benefits obtained and the availability of treatment alternatives. 

8.5 Geriatric Use 

Of the total number of patients administered 32 mg ZILRETTA in clinical studies (N=424), 143 patients were 65 years of age or older. No overall differences in safety or effectiveness were observed between elderly and younger subjects, and other reported clinical experience with triamcinolone acetonide has not identified differences in responses between the elderly and younger patients, but greater sensitivity of some older individuals cannot be ruled out.
