I took Lexapro for a month one time. Luckily I happened to also be seeing an endocrinologist so I happened to have before and after blood work. A few weeks after Lexapro my prolactin level spiked to far higher than is normal for a male. The endocrinologist was worried I had a prolactinoma and had me get an MRI! I stopped Lexapro and gradually the prolactin level went back to normal, but it took a while. There are far more effects from these drugs than are well documented or acknowledged by most of the medical community. I had to go digging myself to find studies and case reports connecting SSRIs to elevated prolactin and suggest the possibility to my doctors who said that's the first they'd heard about it. If your hormones are messed up or you're feeling more gender nonconforming, work with your doctor to see if it's your SSRI.
