Triamcinolone Acetonide Ointment and Breastfeeding
No studies have been done to determine if triamcinolone acetonide ointment (Kenalog ointment) passes through breast milk. Other similar steroids are known to pass through breast milk in small amounts, so it is thought that only minimal amounts of this ointment would pass through breast milk. However, due to the unknown risks, talk to your healthcare provider before using triamcinolone acetonide ointment while breastfeeding.
At this time, it is unknown if triamcinolone acetonide ointment (Kenalog® ointment) passes through breast milk. Therefore, if you are breastfeeding or plan to start, you should talk with your healthcare provider before using triamcinolone acetonide ointment.
No research has been done to see if triamcinolone acetonide ointment passes through breast milk. However, other similar steroids are known to pass through breast milk. Reassuringly, even when steroids are taken by mouth or by injection, only a small amount passes through breast milk. This implies that topical use of steroids (which are applied directly on the skin) would probably result in very tiny amounts (if any) passing through breast milk, although this is not known for sure.
Direct skin-to-skin contact (for areas where the ointment has been applied) should be avoided, to prevent exposing the baby to the ointment by skin transfer. Also, avoid applying it near or on the nipple; if this is not possible, make sure to completely remove the ointment before nursing your baby.
Because this ointment is usually effective for quickly relieving skin inflammation, some mothers may wonder if they could use it on a diaper rash. Never apply this (or any other medication prescribed for yourself) on a diaper rash without first checking with your healthcare provider. Young children are more likely to absorb a dangerously high amount of the medication, especially when it is applied to broken skin (like a diaper rash) and particularly when the area is covered (such as by a diaper).
