Prescribed medication for PC, possibly? (6)
I believe the answer is:
tablet
This clue is a double definition.
'prescribed medication' is the first definition.
(medication in tablet form)
'for pc possibly?' is the second definition.
(as in a tablet computer)
(Other definitions for tablet that I've seen before include "PC" , "Small bar of soap" , "Battle (anag) - pill" , "A small pill or an inscribed panel on wall" , "Stone slab; pill" .)
