The acidity has been killing me this whole pregnancy and someone suggested famotidine. Before i take anything i want to check if its actually ok during these months. I'll confirm with my doctor too but wanted others view first.
Please don't take any acidity medicine on your own yaar. Even if it's commonly used, only your gynac should say yes after checking you. Mine prescribed something for my acidity rather than me picking it up myself.
My acidity was terrible too, I really feel you. My doctor gave me something for it but I never bought any tablet without asking her first. For mild burning, eating small meals and not lying down right after eating helped me a lot.
Honestly the safest thing is to ask your own doctor about this specific medicine. Some are considered okay in pregnancy but it really depends on your situation. I'd never decide medication myself during these months.
