UK Warns of Pregnancy Risks Tied to Weight Loss Drugs
If you're a woman in the UK taking weight-loss or diabetes drugs like Ozempic or Mounjaro, you need to be extra careful about getting pregnant.
These medicines aren't safe for babies.
You should talk to your doctor immediately if you become pregnant while using them and stop the medicine.
Also, some of these drugs can make birth control pills less effective, especially Mounjaro, so use other methods like condoms.
Always get your medicine from a doctor, not from places like beauty salons, to stay safe.
If you feel a bad stomach pain, seek medical help right away.

Medicines like Ozempic and Mounjaro should not be taken if pregnant or planning to become pregnant.
Mounjaro may reduce the effectiveness of oral contraceptives; barrier methods are advised.

Users are reminded to get prescriptions from healthcare professionals and avoid unregulated sources.
