I’ve had a couple of emails back and forth today with a Dr through my provider, last one was at 7:30pm!
He is happy for me to stay on my oral progesterone for now as I am on and have been on the same lower dose of Mounjaro for over 9 months (I am buying 5mg pens), and only on HRT for 3 months, but said if they were to increase my Mounjaro strength it would be a good idea to look at non oral methods first, perhaps taking the utrogestan vaginally to ensure absorption isn’t affected.
He mentioned he had spoken to some patients on 12.5mg/15mg who had noticed reduced efficacy of their progesterone with occasional bleeds so it was important to monitor and act on any symptoms (he didn’t say what was recommended to them, I would guess it would be to speak to their GP as they would with any unusual bleeds).
I think it is worth a conversation with your own provider or GP with your own Mounjaro history, not only but more so if on higher doses and/or been through more changing doses/schedules, had a lot of side effects and if you have had any symptoms of your oral progesterone not working as well.
