How many lithium talets would cause an overdose?

The amount of lithium that can lead to an overdose varies based on individual factors such as body weight, kidney function, and tolerance to the medication. Generally, lithium toxicity occurs at serum levels above 1.5 mEq/L, and acute overdose can happen with doses as low as 2 grams. It's critical to follow prescribed dosages and consult a healthcare professional if there's any concern about overdose or toxicity. If an overdose is suspected, immediate medical attention is necessary.
