It’s important for you and your baby that you stay well during your pregnancy. If you become pregnant while taking fluoxetine speak to your doctor. Do not stop taking your medicine unless your doctor tells you to.

Fluoxetine has been linked to a very small increased risk of problems for your unborn baby. However, if your depression is not treated during pregnancy this can also increase the chance of problems.

You may need to take fluoxetine during pregnancy if you need it to remain well. Your doctor can explain the risks and the benefits, and will help you decide which treatment is best for you and your baby.


Fluoxetine and breastfeeding

If your doctor or health visitor says your baby is healthy, fluoxetine can be used during breastfeeding. It has been used in many breastfeeding mothers without any problems.

Fluoxetine passes into breast milk, usually in small amounts. It has been linked with side effects in very few breastfed babies.

It is important to continue taking fluoxetine to keep you well. Breastfeeding will also benefit both you and your baby.

If you notice that your baby isn’t feeding as well as usual, or seems unusually sleepy, or if you have any other concerns about your baby, then talk to your health visitor or doctor as soon as possible.


Cautions with other medicines

Some medicines and fluoxetine can interfere with each other and increase the chances of you having side effects.

Tell your doctor if you’re taking these medicines before you start fluoxetine:

  • any medicines that affect your heartbeat – as fluoxetine can speed up or change your heartbeat
  • any other medicines for depression. Some rarely used antidepressants can interfere with fluoxetine to cause very high blood pressure even when they have been stopped for a few weeks.

Mixing fluoxetine with herbal remedies and supplements

Do not take St John’s wort, the herbal remedy for depression, while you are being treated with fluoxetine as this will increase your risk of side effects.
