What is caffeine?

Caffeine is a drug that comes from the leaves, nuts and berries of certain plants. Caffeine works as a stimulant, speeding up the brain and activating the nervous system.

What foods and drinks contain caffeine?

Caffeine can be found in a range of foods and drinks.

It is commonly found in:

  • coffee
  • tea
  • chocolate
  • cola
  • energy drinks

Some caffeine products are not considered safe for consumption and have been banned in Australia and New Zealand. These products usually come in the form of powders and syrups and are typically marketed as sports supplements. Food standards codes in Australia also require the clear labelling of products. This helps to advise people of products that are not suitable for young children and pregnant or breastfeeding women. Products containing caffeine must list caffeine as an ingredient on its label.

What medications contain caffeine?

Some prescription and over-the-counter medications have caffeine. Most commonly, medications for coughs and colds, headaches and some slimming medications have caffeine.

Its best to speak to your doctor or pharmacist before taking any medication or supplements while pregnant or breastfeeding.

How much caffeine is safe during pregnancy and breastfeeding?

The recommended maximum amount of caffeine you should have during pregnancy and breastfeeding is 200mg per day (in total).

What are the risks of having too much caffeine during pregnancy?

Having too much caffeine during pregnancy may increase the risk of complications, including miscarriage, stillbirth, low birth weight and/or having a baby who is small for their gestational age.

Some women find they become more sensitive to caffeine during pregnancy, reporting that even small amounts make them feel jittery and anxious.

Caffeine can also affect sleep, causing pregnancy insomnia and it may make morning sickness worse. Another side effect is more frequent urination (needing to wee more often) and bladder irritation.

Cutting back or stopping caffeine completely is made easier for some women who report that they don’t often like its smell during this time.

What are some alternatives to caffeine?

If you’re used to a few cups of coffee or tea each day, you may have withdrawal symptoms when you stop. This can include headaches, irritability, tiredness and feeling ‘on-edge’. Keep in mind, these symptoms are temporary, lasting up to about a week, and they will go away.

You can replace tea and coffee with:

  • plain water with lemon or lime pieces — but be mindful that acid can affect tooth enamel and lead to decay so rinse you mouth with plain water after drinking acidic fluids
  • herbal teas — make sure the teas are caffeine free
  • plain fruit juice or fruit juice diluted with water or soda water so it’s not so sweet
  • vegetable juice
  • a glass of milk
  • unsweetened soft drinks

If you’re struggling to cut back the amount of caffeine in your diet, speak to your GP or maternity care provider for advice.
