Yes!!! I am just now seeing this is from 2021 but I have been on Risperidone for a couple of years at least and for 1 year and 3 months of that time, I was on a birth control implant (Nexplanon) in my inner left arm. I did not have a period the entire time I was on the birth control implant, but I thought it was just because of the Nexplanon. Once they removed it in March earlier of this year, I waited and waited for months for my period to start again (letting me know I was in good health & fertile). I did not get my period back. In fact, around May, just two months after having the birth control removed from my arm, I started having intense hot flashes (like 30 for 30 minutes a day) and other pre menopausal symptoms.
Not until September did I find out from some August tests that my PROLACTIN levels were "very elevated and needed to see an Endocrinologist" usually indicating a type of pituitary tumor, if not due to one or more of the medications I am on. I had my MRI after waiting a couple of months and the results came back in less than 24 hours. I did not have a tumor. I spoke with my psychiatrist early the next morning and she told me "ok it's the Risperidone causing the elevated Prolactin levels- we need to taper you off immediately and increase your Seroquel" so I am in the middle of my 3 week taper now and am still having menopausal symptoms and now even some Resperidone withdrawals but very mild withdrawals. She decided instead of just taking Seroquel at night, that I would take a quarter of my night dose twice a day but after taking my first quarter dose earlier today, I feel like shit from sleeping all day and I had to miss training at a really good, new job and my stomach feels sick from binging, which my PCP warned me of when I told him she would increase the Seroquel.
So bottom line, medications have a lot more negative side effects than we'd ever think possible
But yes you need to have your Prolactin levels checked if you're still having this problem. I am spreading the word on the internet about Risperidone and what it can do to the body when it elevates Prolactin levels, which is a very essential hormone in the endocrine system.
Hope this helps anybody looking for answers!
