View company portfolio →What Impress Flash (Clozapine) is used for
Clozapine is an antipsychotic medicine from the 'atypical' group. It changes the activity of certain natural chemicals in the brain. It is a specialist medicine: it is used only when other antipsychotic medicines have not worked or have caused side effects that could not be managed. Because it can sometimes cause a dangerous drop in the white blood cells that fight infection, everyone taking it needs regular blood tests, and it is started and monitored by a specialist mental health team or clozapine clinic.
- Schizophrenia, when at least two other antipsychotic medicines have not worked or could not be taken because of side effects
- It can reduce symptoms such as hearing voices, frightening thoughts and worrying changes in behaviour
- In some countries, severe problems with thinking, mood and behaviour (psychosis) in people with Parkinson's disease, when other medicines have not worked
Get medical help straight away if
- Contact your doctor or clozapine team straight away for any sign of infection, such as a fever or high temperature, chills, sore throat, flu-like illness, mouth or gum sores, wounds that heal slowly, or pain or burning when you pass urine. These can be signs of a very low white blood cell count.
- Get urgent help for severe constipation, a swollen or painful tummy, being sick, or not being able to pass stools. Constipation caused by clozapine can block the bowel and can be life-threatening.
- Call an ambulance or go to the emergency department for a fit (seizure), fainting or collapse, chest pain, sudden breathlessness, or swelling of the face or throat.
- Contact a doctor straight away for chest pain, extreme tiredness, a flu-like illness, breathlessness, swollen legs or a fast or uneven heartbeat. These can be signs of heart inflammation (myocarditis) or heart muscle damage.
