- Do not translate it as 'этамбутал' (direct transliteration) in non-technical contexts; the Russian term 'этамбутол' is the standard. Be aware that 'EMB' is also a recognized abbreviation.
Common Mistakes
- Misspelling as 'ethambutal', 'ethambutrol', or 'ethabutol'. Incorrectly using it as a countable noun in plural without a quantifier (e.g., 'He takes ethambutols' is wrong; 'He takes ethambutol tablets' is correct).
