Wegovy and Pregnancy: What the Guidance Says and What to Do Next

The core question: is it safe to be pregnant on Wegovy?

The short answer is no, and the reasoning matters. Wegovy is not licensed for use in pregnancy. Animal studies have shown potential harm to a developing foetus at doses comparable to those used in humans, and there is no adequate human safety data to suggest otherwise. The SmPC (the prescribing document that governs how Wegovy is used in the UK) lists pregnancy as a contraindication, and the NHS medicines page for semaglutide reflects this guidance directly.

There is a misconception that slips into online conversations on this topic: that because semaglutide helps regulate blood sugar and weight, it might actually be beneficial during pregnancy. This is understandable (GLP-1 medicines do fascinating things metabolically) but the licensed evidence simply does not extend to pregnancy, and taking an unlicensed medicine at a critical period of foetal development is a risk no responsible clinician would recommend. The kindest thing is to let that idea go.

If you are currently pregnant on Wegovy, stop taking it and speak to your GP or midwife as soon as you can. This is not a reason to panic. It is a reason to act.

What happens to the medicine after you stop?

Semaglutide has a half-life of roughly one week, which means it takes a number of weeks to clear from your system after your final dose. This is worth knowing not because it changes the immediate advice (stopping promptly is still the right call) but because your GP or midwife may factor it into their assessment of your situation, particularly in the early weeks of pregnancy.

The MHRA advises that women of childbearing age use effective contraception while taking GLP-1 receptor agonists and for a period after stopping, before trying to conceive. If pregnancy was unplanned, that timing context helps your care team build a clearer picture, and our page on what to do if you got pregnant on Wegovy covers this scenario in more detail. You can find more detail on semaglutide, pregnancy and what to expect if you are looking for a fuller overview of the clinical picture.

Breastfeeding carries a similar caution. Semaglutide is not recommended while breastfeeding, and under-18s are outside the licensed population entirely. If you are in any of these situations, the conversation belongs with your healthcare team, not with a treatment page.

Planning to conceive: what to discuss with your prescriber before you try

For women who are planning a pregnancy rather than already pregnant, the question looks slightly different. Many people reach a point on Wegovy where they have lost meaningful weight, feel well, and want to start a family. The right time to stop treatment, and how to approach that transition safely, is a clinical conversation.

A prescriber can talk through the wash-out period, what to expect as appetite returns after stopping, and how to protect the progress you have made through diet and activity in the interim. Understanding whether you can get pregnant on Wegovy and what that means for your fertility planning is a helpful part of that discussion. The NHS England guidance on weight management injections is a useful starting point for understanding the broader landscape around GLP-1 medicines and fertility planning.

If you have questions about whether a weight-loss medicine might be appropriate for you at any point, including before or after a pregnancy, our clinical team at nume (actually, at nume) reviews consultations personally. Every consultation is read by a GPhC-registered Independent Prescriber, not processed automatically. You can also browse weight-loss treatment options to understand what is available once you are in a position to consider treatment again.

When to get medical help, and who to contact

If you discover you are pregnant while taking Wegovy, contact your GP or midwife the same day if possible. Do not simply wait for your next scheduled dose and skip it, make contact. If you have ongoing concerns about early pregnancy symptoms, your GP surgery or NHS 111 are the right routes.

Should you experience any unusual or worrying symptoms after stopping semaglutide, you or your healthcare professional can report these through the MHRA Yellow Card scheme, which exists precisely to capture this kind of real-world safety information. It helps protect future patients.

If you were taking Wegovy privately and are unsure what to do next regarding your treatment or prescription, our support team is available seven days a week. We can liaise with your prescriber and help you navigate the pause in treatment properly. Once you are ready to explore treatment again in the future, starting a free consultation takes only a few minutes.
