Caffeine during pregnancy

Caffeine during pregnancy

While having large amounts of caffeine does not appear to cause birth defects, drinking high amounts of caffeine may make it more difficult to become pregnant.
It may also increase the risk of miscarriage or having a baby with low birth weight.

Most evidence on the risk of caffeine use and pregnancy is not conclusive. Most evidence suggests that having less than two standard cups of instant coffee a day is safe.
Caffeine is a chemical found in many foods and drinks, including coffee, tea and cola. It affects the nervous system and can cause irritability, nervousness and sleeplessness.
It is best to limit the daily amount of caffeine to 300mg a day or avoid it altogether.
The approximate amounts of caffeine found in food and drinks are:
  • one cup of instant coffee: 60-80mg
  • one cup of filter coffee: 60-120mg
  • one cup of tea: 10-50mg
  • one 375g can of cola: 48.75mg
  • one 250ml can of energy drink: 80mg
  • one 100g bar of milk chocolate: around 20mg.
Decaffeinated varieties are an option which contains little caffeine; however, safe levels of decaffeinated products for pregnant women are unknown.
Energy drinks are not recommended during pregnancy as they may contain high levels of caffeine, and other ingredients not recommended for pregnant women.
Some cold and flu remedies also contain caffeine. Talk to your midwife, doctor or pharmacist before taking these remedies.
