You can find detailed information about this drug in the official Patient Information Leaflet (PIL), including what it's for, how to take it, possible side effects and safety information. This leaflet should come with your medication (usually inside the box). You can also access it online as a PDF by clicking these links:
If a drug can come in different forms (such as tablets or liquid), there may be a separate PIL for each one. You should look at the PIL for the particular form and dose you've been prescribed. All PILs are available online on the electronic Medicines Compendium (eMC).
Warning: If you become constipated while taking clozapine, tell your doctor or pharmacist right away. Constipation is a common side effect from clozapine, but in rare cases this may develop into a very serious condition, so it's important to seek treatment as soon as you can.
If you have any questions about your medication you can talk to your doctor, someone at your pharmacy or call NHS 111.
