So ive had horrible heartburn to the point that i couldnt breathe. Dr told me to take Zantac 150. And it works....butttt ive been on it three 4 days. It has made me feel funny. A little light headed, face breaks out in hives (ive always had hives and pre preggers had to take on zyertec a day to keep them at bay lol) I thought nothing of this until yesterday i was in line at marshalls and almost passed out! I got red blotches all over my body started dripping sweat felt like my throat was closing and had to sit. Thank god my mother in law was with me and sat with me. It went away after a little bit but it was really scary. What else have people been taking for heartburn i think im going to try something else. Just want to make sure it is safe
