In special cases, women may be advised not to breastfeed. These instances include when a woman is taking certain medications or drugs, when she has been diagnosed with a specific illness, or when other specific conditions apply.

Medications/Other Drugs and Breastfeeding

Certain medications are known to be dangerous to infants and can be passed to your infant in your breast milk. Women taking the following medicines should not breastfeed and should speak with their health care providers before considering breastfeeding:

  • Antiretroviral medications (for HIV/AIDS treatment)1
  • Anxiety medications2
  • Birth-control medications containing estrogen3
  • Cancer chemotherapy agents1
  • Illegal drugs1
  • Certain medications prescribed to treat migraines, such as ergot alkaloids4
  • Mood stabilizers, such as lithium and lamotrigine4,5
  • Sleep-aid medicines2

In addition, women who are undergoing radiation therapy should not breastfeed, although some therapies may require only a brief interruption of breastfeeding.1

The above list of medications and other drugs is only a guideline. Before breastfeeding, you should speak with your health care provider about all medications that you are taking.2 These include prescribed medications, over-the-counter medicines, vitamins, and herbal therapies.

Medications that are safe during pregnancy may also be safe for you to continue while you are breastfeeding, although you should check with your health care provider to make sure they are safe before you breastfeed.2

Contact your infant's health care provider if you see any signs of a reaction to your breast milk in your infant, such as diarrhea, excessive crying, or sleepiness.2

Health Conditions and Breastfeeding

Women with certain illnesses and infections may be advised not to breastfeed because of the danger of passing the illness or infection to the breastfed infant.

If you have any of the following conditions, breastfeeding your infant is NOT advised. For more information, speak with your health care provider:1

  • Infection with human immunodeficiency virus (HIV)
  • Infection with human T-cell lymphotropic virus type I or type II
  • Untreated, active tuberculosis

If you are sick with the flu, including the H1N1 flu (also called the swine flu), you should not stop feeding your infant expressed milk. You should avoid being near your infant, however, so that you do not infect him or her. To avoid infecting your infant, someone who is not sick should give your infant your expressed milk.6

For more information on the flu, including the H1N1 flu, visit the following Centers for Disease Control and Prevention webpage: http://www.cdc.gov/flu/.  

Domestic and International Guidelines on HIV/AIDS and Breastfeeding

In the U.S. and other developed countries, the American Academy of Pediatrics and the CDC recommend against breastfeeding if you are HIV positive.1,7 Without any specific interventions to reduce transmission, infants breastfed by HIV-positive mothers have a roughly 15% chance of acquiring HIV through the breastmilk. This rate increases if infants are breastfed longer or for mothers with newly-acquired HIV.8

Only HIV-positive mothers living in developing countries should consider breastfeeding their babies, especially if a safe and reliable source of infant formula is unavailable.9 This is because breastmilk may protect against malnutrition and diarrhea, which are major causes of infant mortality in some areas of the developing world. If an HIV-positive woman decides to breastfeed her baby, research indicates that the risk of transmitting HIV to her baby is reduced if she exclusively breastfeeds (does not use a combination of formula and breastmilk) and if she and her infant take antiretroviral drugs.9,10

Other Considerations and Breastfeeding

In some additional situations, or if women or infants have certain health conditions, women may be advised not to breastfeed or may have difficulty breastfeeding.4

  • Women with certain chronic illnesses may be advised not to breastfeed, or will be advised to take steps to ensure their own health while breastfeeding. For example, women who have diabetes may need to eat slightly more food while they breastfeed to prevent their blood sugar levels from dropping. Also, women who are underweight, including those with thyroid conditions or certain bowel diseases, may need to increase their calories to maintain their own health during breastfeeding.
  • Women who have had breast surgery in the past may face some difficulties with breastfeeding.
  • Women who actively use drugs or do not control their alcohol intake, or who have a history of these situations, also may be advised not to breastfeed.
  • Infants who have galactosemia—a rare metabolic disorder in which the body cannot digest the sugar galactose—should not be breastfed. Galactosemia is detected by newborn screening, allowing proper treatment and diet to begin immediately. If not detected, the galactose builds up and becomes toxic for the infant, leading to liver problems, intellectual and developmental disabilities, and shock.
