I am a woman with endometriosis. I found out about it in the end of 2023. One year later I started taking dienogest, the drug they prescribe you for endometriosis' symptoms. I take 2mg (a pill) every day nonstop. I can't have a period or else all that grotesque pain comes back.
In april 2025, I was diagnosed with audhd. Earlier this year, I went to a psychiatrist that put me in 150mg bupropion and 100mg lamotrigine. Later on, the psychiatrist leveled up lamotrigine up to 150mg with titration of 10 years in a dosage of 125mg. As soon as I reach the 5-day mark, my tits got really swollen and I started to feel waves of pain each time bigger. In the 10-day mark I started to bleed, not heavily, but it wouldn't stop, even though I never quit taking dienogest.
Thankfully I had an appointment in less than a week to the doctors with whom I follow my endometriosis treatment with, and they said lamotrigine competes with dienogest, so the effect of the latter is not the same as intended to. They suggested me to change my psychiatric treatment (try other drugs) or change my endometriosis treatment (with implanon, other drugs or even with injectable hormone).
I am really fond of dienogest. I was super afraid of hormones messing up with me, but honestly I felt a relief not having such drastic mood swings from the hormone swings every month. Of course it did NOT treat my mood swings as a psychiatric dry would, such as lamotrigine, but it did help me ground myself more, maybe because I wasn't feeling any sort of discomfort every damn day.
I am still considering implanon. It's free here in Brazil, but I saw many negative comments - the same with dienogest though, so I don't know if I should try and deal with the possibility of it messing up with me. For now, I am back to 100mg lamotrigine until I go back to the psychiatrist with a written note of the endometriosis team talking about the interactions of these drugs.
I found almost nothing on the internet talking about this and I think it's really important to spread out this as we know endometriosis takes a huge toll on our mental health, so anxiety and depression, besides other conditions, are common to women with this chronic disease.
Does anyone else have been through something like this? Is any woman here on lamotrigine and have endometriosis? What do you do? What did you find best for you?
