Hello girls ?? I recently had a lot of stomach pain, my doctor prescribed omeprazole 20mg to take in the morning and evening. I'm breastfeeding my 5-month-old daughter, I'm afraid it might affect her, although the doctor doesn't know that I'm breastfeeding. I read online that it's contraindicated or should only be taken at 20mg per day. Who has taken these pills while breastfeeding? Is it even possible to take them while breastfeeding? What did people take for stomach pain?
