In many cases, medication is an important part of restoring someone to good health and wellbeing.

It can be used as a short-term solution for a person overcoming an immediate crisis or may be taken longer-term for more severe and ongoing mental illnesses.
Doctors at WLMHT may recommend medication if someone’s symptoms are so severe that they are struggling to cope with everyday life. Medication can reduce the worst symptoms, making it easier for a person to talk to talk to their care team and get the most benefit from a talking therapy.

Side effects

While medication can be very successful at relieving symptoms, there can be side effects, although not everyone will experience them. They are different for each medication, and range from the mild (drowsiness) to the relatively rare but more serious (liver failure and heart problems).
We will always monitor people very carefully to make sure they are on a medication that is right for them and not experiencing negative health effects that outweight the benefits.

Types of medication

There are four main types of medication:

  • Antipsychotics to relieve symptoms of psychosis.
  • Antidepressants to relieve symptoms of depression.
  • Mood stabilisers to moderate extreme mood changes.
  • Tranquilisers for the relief of anxiety.

Medicines formulary

The formulary is a list of medicines used for mental health conditions across WLMHT. It is based on the Maudsley Prescribing Guidelines and should be taken fully into account when prescribers are exercising their clinical judgement.
