Part 2: Are you allowed to drink water to help you swallow a pill on a fast day?

What if a person needs water to drink down  the pill, or in general, a person who has to   take medication on a fast day needs a little  bit of water? So on a regular fast day like   Shiva Asar b'Tammuz or Asarah B'Tevet, poskim  say if a person needs to take water less than   a melo logmav, less than a cheekful, which is  about 1 oz or less than an ounce of water with   the pill. So then that's acceptable. Again,  provided the person really needs the pill,   they're not feeling so well, they have a headache.  On Tisha B'Av, so then poskim say we need a higher   level of need before one takes water with their  pill. So if a person has a migraine headache,   for instance, they really can't function,  they have to lay down, they have the status   of a choleh, then they could take again the  melo logma, that little bit of water, together   with the pill to help it go down. Of course, it's  always worthwhile to speak to a rabbi, especially   a person who's not sure what level of discomfort  they're up to. It's best to check in with a rabbi.
