What is Lithium for?

Lithium is a mood stabilizer. It can be used to treat and prevent mania, bipolar disorder, recurrent depression, and self-harming or aggressive behaviour. The exact mechanism of action of Lithium is still unknown, but it is thought to be related to the enhancement of nerve cells connecting certain brain regions that regulate mood, mind and behaviour. Lithium is effective in reducing the frequency and severity of manic episodes.

How to use it?

The doses of Lithium vary between different products and are adjusted according to the concentration of Lithium in your blood. Regular blood tests are therefore required if you are taking Lithium. Lithium can be taken once, twice or three times daily. Your doctor will adjust your Lithium dose based on your response. Lithium has a very narrow therapeutic window and hence the dose of Lithium must be controlled precisely. Symptoms of Lithium toxicity like extreme thirst, frequent urination and abnormal movement start to appear when the blood Lithium level reaches above 1.5 mmol/L (1.2 mmol/L for elderly). Remember to stay hydrated to avoid toxicity.

What are the side effects of Lithium? 

Common side effects of Lithium include metallic taste, thirst, nausea, diarrhoea, tremors, blurred vision, delirium, loss of kidney functions, hypothyroidism and ECG changes.
