Q. If I am having a mild allergic reaction, can I swallow (on Tisha Beav) an anti-histamine without water? How about on Yom Kippur?

A. Horav Dovid Pam Shlit’a maintains that if the anti-histamine is inside a capsule it is permitted on Tisha Beav when taken without water.

On Yom Kippur however, besides the eating prohibition, it is also forbidden to do avoidable Refuah and healing.
