Question:
May I take tums on Shabbos for heartburn? Also, if I like the taste, do I make a bracha rishona?
Answer:
Thank you for your question.
Under ordinary circumstances we should not take tums on Shabbos, unless the heartburn is so bad that the person’s whole body feels weak from it.
When taking tums, since it is flavored and we enjoy them, the bracha is shehakol.
Best wishes
