Lithium is used to treat some mental health problems such as bipolar disorder. It is also sometimes used for other conditions.
Take lithium regularly as directed with food and a glass of water.
The controlled release (CR) tablets can be halved, but do not crush or chew them.
Take the missed dose as soon as possible. If it is close to the time for your next dose, skip the missed dose and carry on as normal. Do not take two doses at the same time.
