Medicines

It's always best to tell your GP, health visitor, dentist, pharmacist or midwife that you're breastfeeding, when discussing medicines.

Small amounts of any medicine you take may pass through your breast milk to your baby.

Generally, the amounts are very low and very few medicines are unsafe while you're breastfeeding.

You should also let your GP know if your baby was premature or had jaundice when they were born, as this may affect what medicines you can take.

What medicines can I take while I'm breastfeeding?

Medicines that can be taken while breastfeeding include:

• most antibiotics
• asthma inhalers
• the painkiller paracetamol - you should check with a GP or midwife before taking paracetamol if it's combined with other medicines

It's fine to have dental treatments, local anaesthetics, routine vaccinations (including MMR, tetanus, flu and COVID-19) and most operations.

If a midwife, health visitor, doctor or pharmacist thinks you need a non-steroidal anti-inflammatory drug (NSAIDs) painkiller for swelling or high temperature, then ibuprofen is thought to be the safest choice.

You can use some methods of contraception, some cold remedies, and some medicines used to treat postnatal depression but not all. Always check with a GP, your midwife, health visitor or a pharmacist, who can advise you.

Is there anything I cannot take while I'm breastfeeding?

Common medicines that are not recommended when you're breastfeeding include:

• codeine
• decongestants that come as tablets, liquids or powders that you swallow
• some nasal decongestants that come as nose sprays or drops - check with a GP or pharmacist before using them
• aspirin for pain relief
• herbal remedies - not enough is known about herbal remedies to guarantee they're safe to use when breastfeeding

Talk to a GP or pharmacist before taking antihistamines for allergies or allergy-related conditions, such as hay fever. Do not stop taking prescribed medicines without talking to your GP.

Illegal drugs and breastfeeding

It's dangerous to take illegal drugs while you're breastfeeding or, indeed, at any time.

They can affect your ability to look after your baby safely and can be passed on to your baby through your breast milk.

It's important to talk to a midwife, health visitor or GP if you're using them.
