Weight Loss Injections
Contraception
For women under age 55 years prescribed weight loss injections privately
If you are taking weight loss injections, Tirzepatide (Mounjaro) may mean that your contraception pills do not work effectively. If you are using the contraceptive pill, please use condoms for four weeks after each dose change, to avoid an unwanted pregnancy. This does not apply to Semaglutide (Ozempic). Please contact the practice for a routine appointment if you want to discuss your contraception.
Hormone-Replacement Therapy
For women prescribed weight loss injections privately and prescribed oral combined HRT or oral progesterone (Medroxyprogesterone / Norethisterone / Utrogestan) in combination with oestrogen patch / spray / gel
If you are using weight loss injections, These may have an impact on the effectiveness of your HRT to adequately protect your endometrium (womb lining). Please do contact the practice for a routine review so that we can discuss potential alternatives.
NHS Prescribing Requests
We have received a high volume of queries regarding prescribing of weight loss injections such as Wegovy and Mounjaro following the published approval by National Institute for Clinical Excellence and Scottish Medicines Consortium. However the funding for this has not yet been agreed either centrally by Scottish Government or locally by any Health Board in Scotland and therefore GPs are not in a position to prescribe these medications.
We have also been advised by NHS Lothian against referring to the Lothian Weight Management Service specifically for weight loss injections at this time. We will update this section once we have received approved guidance regarding this.
