The words aa q.s. is an abbreviation which is used in
pharmacy. This is usually written by prescribers and then translated by
pharmacists. The aa is derived from Latin which means “of each” while q.s. is
also derived from Latin which means “a sufficient quantity”. This simply means
that there is equal amount of Hytone 1% cream and Lotrimin 1% cream in the
