Types & Choice
Are there different types of mood stabilisers?
There are different types of medication that can help stabilise your mood. The National Institute of Health and Care Excellence (NICE) produce guidelines for the assessment and treatment of mental illnesses, such as bipolar disorder and schizoaffective disorder. Your doctor should use these guidelines to decide which medication to offer you. You can find these in the further reading section below.
The most common mood stabilisers are listed below.
Lithium is used for the long-term treatment of mania. It can reduce how often you get an episode and how severe they are. It has been found to reduce the risk of suicide.
NICE guidance for bipolar disorder recommends lithium as a first choice to treat episodes of mania and also for long-term treatment.
To make sure that the lithium is working properly and is not at a dangerous level, you should have tests to check the lithium levels in your blood every 3 to 6 months. Your doctor may give you a booklet to keep a record of your lithium levels.
Lithium comes in 2 forms. A tablet and a liquid.
The tablets are made from lithium carbonate. There are different brand names for the tablets. Some of these are:
- Priadel, and
The liquid is made from lithium citrate. The main brand names for the liquid are:
- Priadel liquid, and
NICE guidance for bipolar disorder recommends valproate to treat episodes of mania and also for long-term treatment. Especially if lithium has not worked or is unsuitable.
Valproate is a medication used to treat epilepsy. But it is also used to treat mania. There are different forms of valproate. Valproic acid comes in the form of tablets and capsules. The main brand names for valproic acid are:
- Depakote, and
Sodium valproate can be given by injection, tablets and granules. The main brand name for sodium valproate are:
- Episenta, and
This is sometimes called Lamictal. It is a medication used to treat epilepsy. It can come in the form of a tablet or a dispersible tablet. Which means that you dissolve it in water before taking it.
It can treat bipolar disorder when depression is the main problem. NICE guidance does not recommend it to treat episodes of mania, or as a first option for long-term treatment of bipolar disorder.
Antipsychotic medication can help to stabilise mood. This type of medication is normally used to treat symptoms of psychosis. Symptoms of psychosisinclude delusions, hallucinations and paranoia. Some of the newer antipsychotics can be used to treat bipolar disorder. NICE guidelines recommend the following antipsychotics if you have bipolar disorder.

Are there any side effects?
If you take mood stabilisers you may find that you get side effects. Some side effects may only last for a short time or become easier to cope with. If you are worried about the side effects of your medication, speak to your doctor. Sometimes a lower dose or changing your medication will reduce side effects.
Side effects of lithium
Most side effects are directly related to how much lithium is in the blood stream. These are some side effects of lithium:
- stomach pain,
- feeling sick,
- a metallic taste in your mouth,
- feeling thirstier and needing to pass urine more frequently, and
- weight gain.
You should get regular blood tests to make sure you have a safe level of lithium in your blood.
Taking lithium can change the amount of sodium in your body. This can lead to higher levels of lithium which can cause poisoning. This can be made worse by diarrhoea or vomiting, not drinking enough water or other medications. If you would like more advice about this, speak to your doctor.
Side effects of valproate
Valproate can cause:
- stomach upset and feeling sick,
- hair loss,
- memory loss,
- problems concentrating,
- feeling sleepy,
- hallucinations, and
In women, valproate can cause increased testosterone levels. This can lead to periods stopping and abnormal hair growth.
Valproate may be linked to a condition called polycystic ovaries in women. This can affect how the ovaries work, which can cause symptoms including excessive body hair, irregular periods, problems getting pregnant or acne.
If you are pregnant, valproate can cause problems with the unborn baby. If you are able to have children, your doctor must not prescribe you valproate unless you are on the pregnancy prevention programme. See below for more information.
Valproate can affect how your liver works, so you will need regular tests. NICE guidance says to test your liver at the start of treatment and every 6 months after that.
Side effects of lamotrigine
Common side effects include:
- joint pain,
- becoming agitated,
- vomiting and diarrhoea,
- dry mouth,
