Breast-Feeding: Medical Reasons Not to Breast-Feed

Breast-feeding offers many benefits to both babies and mothers. It can help protect babies from some allergies and sickness. It’s a comfort for both mother and baby. However, there are certain things that could mean you should not breast-feed your baby.

What kinds of problems mean a baby should not be breast-fed?

Some babies are born with diseases that keep them from digesting breast milk. A special infant formula is needed for these babies.

What kinds of problems mean a mother should not breast-feed?

Your healthcare provider may advise you not to breast-feed if:

  • You have HIV infection.
  • You have a severe illness, such as an infection in your bloodstream. If you have a minor illness like a cold, you can still breast-feed your baby. Just be sure to protect your baby by washing your hands before each feeding.
  • You are infected with a herpes virus that causes sores on your breasts. Do not breast-feed until the sores are healed.
  • You are taking medicines that can pass into your breast milk and harm your baby. This includes certain sedatives, antiseizure medicines, cancer medicines, and medicines that affect the immune system. Call your healthcare provider or lactation consultant to ask about your medicines.
  • You have hepatitis B. However, it may be safe to breast-feed your baby if your baby was given a hepatitis B shot within 48 hours after birth.
  • You have hepatitis C and your nipple is cracked or bleeding.
  • You have tuberculosis. However, you can breast-feed if you are being treated for TB.
  • You are using marijuana, cocaine or other drugs, drinking alcohol, or smoking cigarettes while breast-feeding your baby. Using these substances while breast-feeding can harm your baby. If you cannot stop using them on your own, get help from your healthcare provider.
