When prescribed most common drugs you either are given one tablet 3 times a day or one tablet 4 times a day to take . I was told that tablets are taken on a 12 hour cycle if so that would mean one tablet 3 times a day would be one every 4 hours (3 x 4 =12) so one 4 times a day would be one every 3 hours (4 x 3 = 12) IS THIS CORRECT. Thank you
