The Medicines and Healthcare products Regulatory Agency (MHRA) are reminding women on popular medicines for weight loss and diabetes to use safe and effective contraception.

This includes GLP-1 medicines, more commonly known by their brand names, including:

  • Ozempic
  • Mounjaro
  • Wegovy
  • Saxenda
  • Victoza

Effective contraception includes oral (the pill) and non-oral (the implant, coil or condoms) forms of contraception.

Those taking the weight loss injection, Mounjaro, who are overweight and using an oral form of contraception, are advised to also use a non-oral form.

Mounjaro may reduce the effectiveness of oral contraceptives in those who are overweight.
