Mixing Caffeine and Lithium
Caution
Heavy caffeine lowers lithium levels, and stopping suddenly can push them back up toward toxic. Keep your caffeine intake steady.
Caffeine increases renal lithium excretion, so heavy coffee or energy-drink use lowers blood lithium levels — and abruptly stopping caffeine can push them back up toward toxicity. The risk is instability rather than an acute event, but lithium has a narrow therapeutic window and this is a real cause of level swings.
The risk here is to the body — breathing, heart, temperature or organs. Set limits before you start, because this kind of harm does not announce itself in time to react.
