More Information on Karbinal ER and Breastfeeding
Karbinal ER is thought to pass through breast milk. However, the amount of the medication found in breast milk is expected to be small.
Karbinal ER should not be used in children younger than two years old, as deaths have been reported in children younger than age two who took medicines containing carbinoxamine (the active ingredient in Karbinal ER). Because of this risk, the manufacturer of Karbinal ER states that women who are breastfeeding should not use the medication.
However, other sources state that small occasional doses are likely to be safe during breastfeeding. Large doses or more than occasional use may cause side effects in a nursing infant, such as drowsiness or irritability.
It is possible that Karbinal ER could decrease a woman's milk supply, as the medication can decrease prolactin, a hormone that is important for breast milk production. However, this effect is mainly seen with high doses of the drug given before breastfeeding is established. Low doses in women who are already breastfeeding may not cause the same problem.
If your healthcare provider recommends breastfeeding while using Karbinal ER, make sure to watch for any possible side effects in your child, such as drowsiness or irritability. Also, let your healthcare provider know if your milk production seems to be affected by the medication.
