Can You Take Wegovy While Pregnant?

Why is Wegovy not suitable during pregnancy?

The straightforward answer is that adequate safety data in pregnant humans does not exist. Animal reproduction studies using semaglutide found evidence of foetal harm at exposures comparable to clinical doses, which is why the Summary of Product Characteristics for Wegovy advises avoiding use during pregnancy altogether.

This is not a theoretical precaution buried in small print. NHS guidance on semaglutide states clearly that Wegovy must not be used in pregnancy, and the same position is reflected in the NHS England weight-management injections guidance. The underlying concern is that GLP-1 medicines affect nutrient absorption, energy balance, and gastric emptying, mechanisms that matter significantly to foetal development, especially in the first trimester.

There is also a practical timing issue. Many people do not realise they are pregnant in the earliest weeks. If you are sexually active and there is any possibility of conception, your prescriber will want to discuss contraception before starting treatment. Take a moment now to check when your last period was and whether you might be due a pregnancy test, it takes under a minute and matters here.

Semaglutide and pregnancy is a topic our prescribers are asked about regularly, and the position has not changed: the medicine stops when pregnancy begins.

What should you do if you become pregnant while taking Wegovy?

Stop taking Wegovy and contact your GP or midwife promptly. You do not need to wait for your next scheduled injection date; the medicine should not continue once pregnancy is confirmed.

The washout period for semaglutide is relevant too. Because it stays in the body for several weeks after the last dose (it has a half-life of roughly one week, meaning meaningful levels can persist for a month or more), NHS England advises that women planning to conceive stop Wegovy with enough lead time to allow clearance before conception. The specific interval should come from your prescriber, who will factor in how long you have been on treatment and your current dose.

If you are already pregnant and have been taking Wegovy without realising, your maternity team needs to know. They will not be alarmed (accidental exposure in early pregnancy is something clinicians are used to assessing) but the information helps them monitor appropriately. You can also explore what is known about semaglutide exposure in pregnancy more broadly for further background.

Does the same guidance apply if you are trying to conceive or breastfeeding?

Yes to both. The advice for people actively trying to conceive is to stop Wegovy before beginning attempts, with a washout period agreed with a prescriber. If you have questions about using Wegovy while pregnant or in the period around conception, our prescribers can walk you through the detail during a consultation.

For breastfeeding, the position is similarly cautious. It is not known whether semaglutide is excreted in human milk, or at what concentration, or what effect exposure might have on a nursing infant. In the absence of that data, the guidance is not to use Wegovy whilst breastfeeding.

These restrictions are consistent across GLP-1 medicines generally. The licence for Wegovy is specifically for weight management in adults who are not pregnant, not trying to conceive, and not breastfeeding. If your circumstances change during treatment, that changes your eligibility. For a fuller explanation of whether you can use Wegovy while pregnant and what the risks involve, we have covered the topic in detail on a dedicated page.

Once pregnancy ends and breastfeeding is complete, many people do return to weight-management treatment. A fresh clinical assessment at that point determines whether Wegovy remains appropriate and at what starting point, decisions best made with a prescriber who knows your full picture.

What are the options for managing weight during and after pregnancy?

During pregnancy, weight management through medicine is not appropriate. NHS dietary and activity guidance, supported by your midwife or GP, is the right framework. Gestational weight gain targets exist and vary by starting BMI, your maternity team can advise.

After pregnancy and breastfeeding, if weight management support is still relevant, the usual eligibility criteria for prescription treatment apply again: broadly, BMI of 30 or above, or 27 or above with a qualifying health condition, assessed by a prescriber. You can read about the treatment options available and what the assessment involves, or check your eligibility directly by starting a free consultation with our clinical team.

Our prescribers regularly support people returning to treatment after pregnancy, and questions about timing, dose restarts, and contraception are part of that conversation. Nothing about the process is unusual or awkward to raise.
