Hello dear,

Thanks for trusting us about your health care.
I can understand your concern here.
Congratulations on pregnancy!
Pantocid- L is a pantaprozole ans lesuperide and drug usually use in gastroesophageal reflux disease.
It is FDA approved category - b drug means its effects can only be studies in animals and usually not harmful to them but use on human body is not established yet.
So you can use this tablets after consulting your doctor if it is very important and there is no other alternative ( means benefits outweigh the risk to fetus).
Hope it is useful, feel free to discuss more questions.
Good luck.
Regards
