Lithium Toxicity: Signs, Risks, and What to Do If You Suspect It

When used correctly, lithium, a mood stabilizer commonly prescribed for bipolar disorder. Also known as lithium carbonate, it has helped millions manage extreme mood swings for decades. But lithium has a narrow safety window — too little won’t help, and too much can be life-threatening. serum lithium levels, the amount of lithium in your blood measured through routine blood tests must stay between 0.6 and 1.2 mmol/L. Going above that range isn’t just risky — it’s a medical emergency.

lithium toxicity, a dangerous buildup of lithium in the body doesn’t always come from taking too many pills. Often, it’s caused by changes in your body’s ability to flush it out. Dehydration, kidney issues, salt restriction, or starting a new medication like an ACE inhibitor or NSAID can cause lithium to build up silently. You might not feel sick at first — but then comes the shaking, the nausea, the confusion. Some people mistake early signs for a stomach bug or the flu. That’s how dangerous it is. If you’re on lithium, you need to know the red flags: persistent vomiting, muscle weakness, dizziness, slurred speech, or blurred vision. These aren’t side effects — they’re warning signs.
