Can you crush or split clozapine?
The answer belongs to the form, not the drug name. An extended-release tablet meters the dose out over hours; crushing it delivers the whole day at once. Match the product below to the one on your box — if yours is not listed, read its own label.

Frequently asked questions
Can you crush clozapine?
It depends on which clozapine product you have, which is why this page quotes each label separately rather than answering for the drug name. The labels we read permit it in the terms quoted above.
Why does it depend on the form and not the drug?
Because the restriction is built into the tablet, not the molecule. Extended-release and enteric-coated tablets carry a coating or matrix that meters the dose out over hours; crushing destroys it and delivers everything immediately. The same drug in an immediate-release tablet often has no such restriction, which is why a list of drug names cannot answer this question and a quoted label can.
What if I can't swallow the tablet?
Ask the prescriber or pharmacist rather than crushing it anyway — most drugs that cannot be crushed exist in another form (liquid, dispersible tablet, patch, or an immediate-release version taken more often) and switching is usually straightforward. Some labels explicitly describe an alternative, and where they do it is quoted above.

Quoted from FDA labels for reference, not medical advice. Never crush or split a tablet against its label to make it easier to take — ask the prescriber or pharmacist, because an alternative form usually exists.
