Who can and cannot take mirtazapine

You can take mirtazapine if you’re over 18.

Mirtazapine normally should not be given to children or anyone under 18. It may increase the risk of self-harm.

Your GP may prescribe mirtazapine if you're under 18 and they think that the benefits of the medicine outweigh the risks.

Non-urgent advice: Check with your GP before starting to take mirtazapine if you:

  • already have a medical condition - such as heart problems, epilepsy and glaucoma
  • have had an allergic reaction to medicine
  • are trying to get pregnant, already pregnant or you are breastfeeding
  • have ever taken any other medicines for depression
  • are taking or have recently taken any other medicines

Diabetes

If you have diabetes, mirtazapine can make it more difficult to keep your blood sugar stable.

Monitor your blood sugar more often for the first few weeks of taking mirtazapine. Discuss your results with a GP. They may make changes to your diabetes treatment if necessary.

Pregnant and mirtazapine

Talk to your GP before taking mirtazapine if you are pregnant or trying for a baby.

If you are pregnant while taking mirtazapine speak to your GP. Do not stop taking your medicine unless your GP tells you to.

Mirtazapine has been linked to a very small increase in health risks for your unborn baby, including persistent pulmonary hypertension of the newborn (PPHN).

You may take mirtazapine during pregnancy if you need it to keep well. Your GP can help you decide which treatment is best for you and your baby.

Breastfeeding and mirtazapine

Talk to your GP if you're taking mirtazapine and breastfeeding or planning to breastfeed.

Mirtazapine passes into breast milk in small amounts and has often been used during breastfeeding without any problems.
