There are a lot of shorthand notations to know for drug orders. These abbreviations are used to simplify frequencies, dosages, routes, and more. Abbreviations may be very similar but have very different meanings. For example, 'q.d.' (every day) compared to 'q.o.d' (every other day). Here are lists of common abbreviations.
1. Morphine Sulfate 10 mg IM q.4.h. p.r.n. pain.
The order is 10 mg of Morphine Sulfate given intramuscularly, every four hours as needed for pain.
2. Amoxicillin 500 mg p.o. q.8.h.
The order is 500 mg of Amoxicillin to be taken by mouth, every eight hours.
3. Albuterol 2.5 mg INH t.i.d.-q.i.d.
The order is 2.5 mg of Albuterol, inhaled, three to four times a day.
