Heartburn is common during pregnancy, affecting 22% of women in the first trimester, 39% in the second and 72% in the third¹. This is because during pregnancy your body produces the hormone, progesterone, which slows down digestion and causes the muscular valve between the oesophagus and the stomach to relax, increasing the risk of gastro-oesophageal reflux. As a result stomach acid is more likely to leak into the oesophagus and cause a burning pain in your chest and throat. Also, as your baby grows, the pressure on your stomach increases and this can force stomach acid into the oesophagus, again causing gastro-oesophageal reflux.

All Rennie® products can be used during pregnancy if taken as instructed and if prolonged intake of high dosages is avoided.

A panel of independent medical experts advised that calcium/magnesium-based antacids, such as Rennie® Peppermint, Spearmint, Rennie® Sugar Free and Rennie® Fruit, should be the recommended treatment for women who suffer from heartburn during pregnancy because of their good safety profile². However it is important to consult your doctor or pharmacist before using any remedies during pregnancy.
