More Information on Breastfeeding and Loniten

There is very limited information available about
 Loniten use in breastfeeding. Although the medication is known to pass through breast milk, it is not known how much of the medication would be passed to the nursing infant or how it would affect the child.
 
Although this lack of information is certainly frustrating, it is important to understand that studies of medications are rarely done in breastfeeding women, as this would usually expose an infant ,who may not directly benefit from the medication, to possible risks.
 
If your healthcare provider recommends taking Loniten while breastfeeding, you may want to watch for potential side effects in your infant. Contact your child's healthcare provider as soon as possible if you notice any Loniten side effects, or if something "just does not seem right." Potential side effects may include but are not limited to:
 
  • Abnormal hair growth
  • Darkening of fine hair
  • Vomiting
  • Difficulty feeding
  • Breathing problems.
