concern about herbal diuretics interacting with lithium
There's concern about herbal diuretics interacting with lithium.
This makes sense. We know Rx diuretics like thiazides, loops, and spironolactone INCREASE lithium levels. Other drugs such as acetazolamide, caffeine, or theophylline DECREASE levels.
A new case report on lithium toxicity reminds us that we also need to watch for herbal diuretics.
