Q. Is it permissible on Yom Kippur to swallow caffeine pills or pain relief pills without water? Can one use caffeine / aspirin suppositories (before or after the onset of a headache),,?
A. Horav Shlomo Miller’s Shlit’a opinion is that during Yom Kippur caffeine pills or pain relief pills should not be used regardless of their covering surface, even without water.
However, one may take before the beginning of the day similar time release pills. (They can also be acquired in the Kollel offices).
One is permitted to use caffeine – aspirin suppositories, before or after the onset of a headache, during Yom Kippur.
(See questions 1175 and 2380).
