Some drugs have commonly used abbreviations, such as INH for isoniazid and TMP for trimethoprim. However, abbreviations may be used inconsistently or confused with other terms or be unfamiliar to some readers. Because of the potential for harm from erroneous interpretation of abbreviated drug names, abbreviations should not be used except in rare instances (eg, trimethoprim-sulfamethoxazole may not fit in a table heading and may need to be abbreviated, eg, TMP-SMX; in that case the expansion should be provided in a table footnote).
