If you are pregnant, planning pregnancy or breastfeeding, speak to a doctor before using GLP-1 weight loss injections. Safety in pregnancy and breastfeeding has not been established so treatment should be stopped.
Why GLP-1 injections are not used in pregnancy
These medicines have not been proven safe in pregnancy. The standard advice is to stop treatment when pregnancy is confirmed or before trying to conceive. Discuss a washout period and contraception with your prescriber.
If you become pregnant while using a GLP-1, contact a doctor as soon as possible for personalised advice.
Breastfeeding and GLP-1 medicines
Breastfeeding safety has not been established. A doctor will help you weigh potential risks and benefits. Alternative approaches can be planned while you breastfeed.
Planning ahead if you want to conceive
Book a preconception discussion with your doctor. Ask how long to wait after stopping, what supplements to start and how to manage weight with food, movement and sleep.
Write a short plan and review it at each appointment so everyone is clear on the next step.
