Safety guide

Weight-loss tablets and pregnancy: what UK guidance says

If you are pregnant, trying to conceive or breastfeeding, this matters before starting or continuing any weight-loss tablet. The consistent position across the medicines covered on this site is simple: weight-loss tablets are not recommended in pregnancy, and you should speak to your prescriber or GP promptly if pregnancy is possible or confirmed.

Short answer

Do not treat this as a medicine you can just carry on with

If you become pregnant while taking a weight-loss tablet, contact your prescriber, GP or relevant specialist promptly and follow the product-specific advice you are given. Do not make a dose change or restart decision from a comparison page alone.

Wegovy pill and pregnancy

Semaglutide, including the Wegovy pill, is not recommended during pregnancy. The product information says it should be discontinued at least 2 months before a planned pregnancy. A prescriber can explain how that applies to your treatment and medical history.

If you find out you are pregnant while taking the Wegovy pill, contact your prescriber, GP or maternity team promptly for product-specific advice. The goal is not to panic or self-manage a change, but to get a clear individual answer quickly.

Rybelsus and pregnancy

The same semaglutide-based caution applies to Rybelsus. It is not recommended in pregnancy, and diabetes in pregnancy needs specialist management, so anyone taking Rybelsus who is pregnant or planning a pregnancy should speak to their diabetes team promptly rather than adjusting treatment alone.

Mysimba and pregnancy

Mysimba is not recommended in pregnancy. If pregnancy is possible, confirmed or planned, contact the prescriber promptly for advice based on the current product information and your own circumstances.

Orlistat and pregnancy

Weight loss is not advised during pregnancy regardless of method, and orlistat is generally not recommended in pregnancy. Speak to a GP, midwife or pharmacist about appropriate support rather than relying on a comparison page for an individual treatment decision.

Breastfeeding

Breastfeeding guidance varies by drug and should be checked directly with your prescriber, GP or pharmacist rather than assumed from a general guide. Do not assume any weight-loss tablet is safe while breastfeeding without checking first.

What to do if you are pregnant or trying to conceive

  • Contact the prescriber, GP or relevant maternity team promptly and use the current product-specific advice for your medicine.
  • Tell every provider involved, including the online pharmacy, your GP and your midwife if relevant, so your records stay consistent.
  • Ask before starting again after pregnancy or while breastfeeding. A prescriber should advise on the medicine, timing and individual circumstances.
  • This page is general information, not medical advice. Suitability always depends on your own health history.
