Treating Hives While Breastfeeding

Antihistamine drugs are one of the most common ways to treat a case of hives, but it is not the choice of treatment when you are breastfeeding. Antihistamines drugs can enter your bloodstream, permeate your breast milk and harm your baby. If you have contracted hives and are also breastfeeding, do not panic yet. Here is how you can start the treatment for hives while breastfeeding (2):

  • Speak to your doctor the moment you notice the rashes. Make sure you inform your doctor that you are breastfeeding your baby. Your doctor may prescribe antihistamines that pass in the breast milk in minimal amounts. Discuss the potential effects the medication may cause you or your baby. Take it as soon as you feed your baby, as it will reduce your baby’s chances of exposure to the same.
  • Check with your doctor if they can identify a specific allergen that triggered hives. Try and avoid exposure to the same to minimize further risk. If it is a food-related allergy, remove that from the maternal diet.
  • Try using a cold compress that will soothe the itching or burning sensation due to hives.
