If you are taking oral progestogen as part of your HRT (for example Utrogestan, Norethisterone, Medroxyprogesterone), then you need to be aware that tirzepatide (Mounjaro) may have an impact on the effectiveness of your HRT. This means your HRT might not protect your endometrium (womb lining) enough.
Please contact the surgery to book an HRT review, as we may need to increase your dose or change you to a different form of medication.
If you do not take your HRT orally (for example, you use a patch, a gel or a Mirena coil instead of a tablet) then you do not need to worry.
