There is a standard code for TB treatment regimens. Each anti-TB drug has an abbreviation (shown in the table on page 112). A regimen consists of 2 phases.The number before a phase is the duration of that phase in months. A number in subscript (e.g. 3) after a letter is the number of doses of that drug per week. If there is no number in subscript after a letter, then treatment with that drug is daily. An alternative drug (or drugs) appears as a letter (or letters) in brackets.
