While rare, your doctor may advise you or tell you not to breastfeed if you:
- Take certain medicines, like anxiety medication or certain migraine medications that are dangerous for babies and can be passed to your baby in your breastmilk
- Have a specific illness (like HIV or active tuberculosis)
- Get radiation therapy, though some therapies may mean only a brief pause in breastfeeding
If you take medicine or have an illness, talk to your doctor before you begin breastfeeding. Medicines that are safe for you to take during pregnancy may also be safe while you are breastfeeding. But you should always check with your doctor before you start breastfeeding. Talk to your baby\’s doctor if your baby shows any signs of a reaction to your breast milk, such as diarrhea, excessive crying, or sleepiness.
