There was a sub-editing error in the article on lithium interactions (Aust Prescr 2020;43:91-3), which has now been corrected. View corrected article.

In the last sentence of the ‘Diuretics’ section, the word ‘increase’ should have read ‘alter’: Other diuretics such as the osmotic methylxanthine (e.g. theophylline) and loop (e.g. furosemide (frusemide)) and potassium-sparing (e.g. spironolactone) diuretics may also alter lithium concentrations.
