PPIs are medicines which reduce the amount of acid your stomach makes, such as omeprazole.7 

Pyrocalm Control, is a branded over the counter omeprazole, the main ingredient prevents the proton pump enzymes, which produce acid to aid digestion, from working properly therefore reducing the amount of acid in the stomach. Pyrocalm can be used during pregnancy and while breastfeeding if other dietary and lifestyle changes aren’t working. 

Medicines can affect the unborn baby. Always talk to your doctor or pharmacist before taking any medicine during pregnancy. If you buy indigestion tablets or omeprazole over the counter; from a pharmacy or supermarket you’re advised to check with your GP before taking it for longer than two weeks.6
