Pregnancy – drug interactions

Patient: Hi I am 32 weeks pregnant and have severe constipation I also have a sinus infection and I am taking amoxicillin 500mg 3 times a day. I wanted to know if it is ok to take Docalax or milk of magnesia to help with my constipation. My doctor said that it was safe to take these for constipation but I was unsure about mixing them while on the antibiotic.

Doctor:
