What Zeldox IM is used for
What Zeldox IM is for
Zeldox IM is used to treat severe agitation or aggression in people with schizophrenia or similar illnesses.
Your doctor may have prescribed Zeldox IM for another reason.
Ask your doctor if you have any questions about why Zeldox IM has been prescribed for you.

How Zeldox IM works
