Most medicines, including those used to treat postnatal depression, can be taken while you're breastfeeding without harming your baby.

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.

But it's always best to tell your doctor, dentist or pharmacist that you're breastfeeding.

What medicines can I take while I'm breastfeeding?

Medicines that can be taken while breastfeeding include: 

  • the painkiller paracetamol – you should check with your GP or midwife before taking other types of painkillers, such as ibuprofen
  • most antibiotics
  • asthma inhalers 
  • vitamins – but only at the recommended dose

You can use some methods of contraception and some cold remedies, but not all.

Always check with your GP, midwife, health visitor or pharmacist, who can advise you.

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

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

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

Talk to a GP or pharmacist before taking antihistamines for allergies or allergy-related conditions, such as hay fever.

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 breastmilk.

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