8 Use in Specific Populations

8.2 Lactation

Risk Summary

(Additions and/or revisions underlined)

There are no data on the presence of SUSTOL in human milk, the effects of SUSTOL on the breastfed infant, or the effects of SUSTOL on milk production. The lack of clinical data during lactation precludes a clear determination of the risk of SUSTOL to an infant during lactation; therefore, the developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for SUSTOL and any potential adverse effects on the breastfed infant from SUSTOL or from the underlying maternal condition.

8.4 Pediatric Use

(Additions and/or revisions underlined)

The safety and effectiveness of SUSTOL in pediatric patients under 18 years of age have not been established.

SUSTOL is not recommended for use in pediatric patients less than 12 years of age because the product administration requires a large gauge needle and an extended administration time.
