Breastfeeding and medications

When supporting breastfeeding mothers, a common issue found is discovering that many are told to stop breastfeeding for either a short period of time or even permanently in some situations, after having medication prescribed.

This can cause a great deal of distress.

The truth is that many medications are compatible while breastfeeding. Some doctors tell women to stop breastfeeding when they have needed to undergo a test or treatment. It’s been known to stop breastfeeding even when having a local anesthetic for an ingrown toenail, which was unnecessary.

It’s important to know that the majority of medications are compatible with breastfeeding. Even in situations where drugs may pose a certain risk, there is usually an alternative.

A variety of different medications

It’s vitally important, however, that you seek out information about any medication from a really good source, and be aware that the information leaflets that you get inside packets of medicines will often say ‘not compatible with breastfeeding.’

Please be aware that this doesn’t mean that the medication will necessarily be harmful to your baby.

It means that the manufacturers haven’t yet done specific studies relating to breastfeeding.

Many of these medications are licensed to give to babies directly. You will find that the amount of that medication that goes through into the breast milk is usually a lot less than the amount that babies are given.

If you find yourself needing to start a new medication which is NOT compatible with breastfeeding, your doctor could delay the medication for a while, or give you an alternative.

Also, please note that older babies and toddlers can metabolize drugs much easier than newborns.

Even in the worst-case scenario, where you find that you do have to stop breastfeeding for a time, you can still keep up your supply by pumping your milkGet a really good quality pump. You can rent hospital-grade double pumps, to keep your supply up. Pump every two to three hours, which will protect your supply while you’re receiving this medication. 

It used to be thought that babies given too many bottles would not be able to come back to the breast again, but we now know this isn’t true.

Babies are hard-wired to feed at the breast, so a temporary interruption does not mean that breastfeeding cannot continue.

In the U.K, an excellent source of information around medications and breastfeeding is The Breastfeeding Network website, where accurate information is provided.
