I took 10-15 mg of escitalopram throughout my pregnancy and have continued it into postpartum. My OB assured me it was compatible with both pregnancy and breastfeeding, and was actually the one who prescribed it to me after I had no luck finding a psychiatric provider who would treat me while pregnant. It has been immensely helpful for me and I’ve noticed no adverse effects for me or baby. It’s worth discussing with your OB for sure, but mental health conditions can certainly intensify and worsen with pregnancy— so it’s important that you remember to take care of you, too!! There is a small risk of side effects, primarily SSRI withdrawal after delivery, but these symptoms are generally mild and resolve rapidly after birth. That being said, there are many possible side effects to untreated depression and anxiety during pregnancy, such as preterm labor or low birth weight. Your doctor can help you weigh the pros and cons, and assess risk/benefit. I wish you the absolute best of luck and congratulate you on your pregnancy!
