my doubt is simple...
the correct Measure Word of:
Appreciate your time!
剂 and 服(fù) are measure words for doses, although I believe that 服 is used only for Chinese medicine. You can use 丸 for pills, and I think that I have seen 片 for tablets. For other forms you might wish to describe it by weight or volume (esp. for liquids).
a single package of a prescription of Chinese Medicine is called 一服（FU）， because you would normally boil the whole package in a pot and drink the produced liquid at once. so one of 服's meaning is taking medicine for both western and chinese medicines. The units of each ingredient in the prescription normally are tael(两) and mace(钱）。
For western medicine, we use 片(pian) for pill, 粒(li) for capsule，and 支（zhi) for bottled liquids, 袋（dai) for pouch, and 板（ban) for foiled pills
