Yes. Eno is safe to consume for pregnant women. However, there is a way to consume this medicine. When your stomach is full, the time taken for antacid performance is slower than usual. Hence, taking Eno on an empty stomach is the best way to consume it to empty the gastric quickly. Also, consuming Eno on an empty stomach makes sure that the medicine stays inside your body for a shorter period. Dissolving Eno in water is always a good idea as antacids work better in liquid form. Though Eno is considered safe for pregnancy and is readily available, it is advised you contact your gynecologist before consuming it.
