I started taking Zofran for nausea on Wednesday, which has been known to cause constipation and was getting worried last night because I hadn't had a bowel movement for a couple of days. My husband ran to the store to get some Milk of Magnesium for me, which my pregnancy book said is okay during pregnancy. The directions on the bottle said to take 2-4 tablespoons. I thought, "I'm pretty constipated, I'd better take 4 tablespoons." Big mistake! First of all, the liquid medication upset my stomach and I threw up my whole dinner about 20 minutes after taking it. The medicine must've gotten through to me somehow and not been vomited up with the rest of my food, because then this morning I had horrible watery diarrhea.
Review of Milk of Magnesia: way too effective at the highest dose.
Also, can irritate the stomach and cause vomiting. After my diarrhea this morning I researched it and found out it's better to start off with a lower dose and see how that goes first. I think I'll try adding more fiber to my life through fruits and vegetables and psyllium husks to see if I can handle things naturally.
