Lithium is a type of medicine known as a mood stabiliser. It's used to treat mood disorders such as:
- mania (feeling highly excited, overactive or distracted)
- hypo-mania (similar to mania, but less severe)
- regular periods of depression, where treatment with other medicines has not worked
- bipolar disorder, where your mood changes between feeling very high (mania) and very low (depression)
Lithium can also help reduce aggressive or self-harming behaviour.
Lithium is available on prescription.
It comes as regular tablets or slow-release tablets (lithium carbonate). Brand names for the tablets include Priadel, Camcolit and Liskonum. It also comes as a liquid that you swallow (lithium citrate). Common brands of lithium liquid are Priadel and Li-liquid.
Key facts
- Lithium may take several weeks or months to work.
- Common side effects of lithium are feeling or being sick, diarrhoea, a dry mouth and a metallic taste in the mouth.
- You'll have regular blood tests to check how much lithium is in your blood. These results will be recorded in your lithium record book.
- You'll be given a lithium alert card to keep with you at all times. In an emergency, this will let health professionals know you're taking lithium.
