Wegovy and Pregnancy: What You Should Know

Before starting any weight loss medication, you should know what to expect and have plenty of information on hand. Aim never to be caught off guard by any aspect of your treatment, because the more educated you are, the smoother your experience should be.

Wegovy is one such treatment, available as both a daily pill and a weekly injection. It demonstrates high rates of effectiveness, with 16.6% weight loss over 64 weeks for the Wegovy pill and 20.7% weight loss over 72 weeks for Wegovy injections. The injections have a higher rate of weight loss, but for those with a dislike of needles, the pill may be preferable.

This article will focus primarily on both forms of Wegovy and their relationship to pregnancy. Pregnancy is often one of the top factors people must consider before committing to a treatment, since, as mentioned prior, you do not want to be caught off guard at any point in your treatment timeline.

Here, we will discuss how Wegovy affects pregnancy and conception, what to do if you become pregnant while on Wegovy, and interactions beyond pregnancy, such as breastfeeding, to keep you up to date on the information you need.

Does Wegovy Affect Pregnancy?

Being on Wegovy can affect your pregnancy in different ways, some positive, some negative - but all you should be aware of before committing to the treatment.

• Fertility: In the pre-stage of pregnancy, studies have found that weight loss can have positive effects on fertility. Positive if you want to be fertile, that is. If you want to avoid getting pregnant, then you may want to increase the amount of protective measures you are taking, e.g using condoms as well.
• Contraception: Unlike other GLP-1 weight-loss treatments like Foundayo and Mounjaro, neither form of Wegovy has any effect on oral contraception. This includes the combined pill and the mini pill, as both will have extremely similar absorption rates on Wegovy as off it. However, certain Wegovy side effects like diarrhoea and vomiting can impact oral contraceptives. 
• Pregnancy: There is limited data available regarding human pregnancy and semaglutide, but there have been plenty of trials on animals. They have shown that having semaglutide in the body while pregnant can result in a higher risk of miscarriage and other major birth complications.

Can You Take Wegovy While Pregnant?

Do not take Wegovy if you are pregnant. It is not currently known whether doing so will have an effect on the unborn child, so you should avoid it for the health of the baby. You must inform your clinician if you become pregnant while taking Wegovy.

Are There Clinical Studies About Wegovy Pregnancy Risks?

Clinical evidence on Wegovy and pregnancy is limited. Because the outcomes are likely to be adverse, it is often considered unethical to run clinical trials on humans. However, from what we do know, using Wegovy while pregnant should be avoided.

Can You Get Pregnant on Wegovy?

Pregnancy can occur on Wegovy, since it is in no way a contraceptive. In fact, it can make some oral contraceptives less likely to prevent pregnancy via certain side effects. In these cases, if you do not wish to become pregnant while using Wegovy and are using oral contraceptives, you should use a secondary form of contraception in addition to make the chance of pregnancy slimmer, like condoms. Wegovy also does not interact with other forms of contraception, such as the contraceptive patch and vaginal rings, so these are options available to you too.

How Long After Wegovy Can I Get Pregnant?

If you are planning to try conceiving, you should stop taking Wegovy at least two months in advance, and this goes for both the tablets and the injections. Let your clinician know well in advance, and they can help with the come-off process.

What Happens If You Get Pregnant on Wegovy?

If you become pregnant while using either form of Wegovy treatment, you will need to speak to your clinician. They will stop your treatment for the time being, as it is currently unknown what the effects of Wegovy are on an unborn child. You should also inform your midwife and/or your GP.

Can I Restart Wegovy After Pregnancy?

Yes, you can restart Wegovy after pregnancy. It is likely that you will be placed at a lower dosage than you left it on, as your body will need time to re-adjust to the medication. Ask your clinician for further information, as this will be a case-by-case scenario.

Can You Use Wegovy While Breastfeeding?

It is not advised to breastfeed while on Wegovy, so you must inform your clinician if you are or are planning to do so. Amounts of semaglutide may pass through breast milk and be consumed by the child, so to ensure their safety, your clinician may halt your treatment. Mounjaro, an alternative GLP-1 treatment, has recently been given the green light to allow for possible breastfeeding while on it, so this may impact your decision on which treatment to use.
