Camcolit tablets contain the active ingredient lithium carbonate, which is a type of medicine known as a mood stabiliser.

What is it used for?

  • Treatment and prevention of mania and hypomania
  • As a 'mood stabiliser' to prevent episodes of depression and mania in people with bipolar affective disorder (manic depression).
  • Treatment and prevention of recurrent depression when treatment with other antidepressants is unsuccessful
  • Aggressive or self-harming behaviour

How does it work?

  • Camcolit tablets contain the active ingredient lithium carbonate, which is a type of medicine known as a mood stabiliser.
  • The way lithium works as a mood stabilising agent is still not fully understood. It is thought that it modifies the production and turnover of certain chemical compounds called neurotransmitters that are found in the brain.
  • Neurotransmitters are involved in transmitting messages between the nerve cells in the brain. Serotonin is one example of a neurotransmitter, as is dopamine.
It is thought that lithium may affect the activity of these compounds in the brain.
  • Lithium is used in several ways. People with bipolar affective disorder (manic depression) suffer from episodes of severe mood swings, which range from abnormally high mood and extreme excitement (mania) to deep depression. Lithium is used to treat the mania, and to stabilise mood after an acute episode of mood swings to decrease the frequency and intensity of these episodes.
  • Lithium is also used to treat recurrent depression that has not been responsive to other antidepressants, and aggressive and self-harming or self-mutilating behaviour.
  • Camcolit 400 tablets are controlled release tablets that are designed to release the lithium slowly and continuously over several hours. This produces a steady blood level of the medicine throughout the day. The tablets can be broken in half, but they must be swallowed with water and not chewed or crushed, as this would damage the controlled release action.
