How Zeldox IM works
Zeldox IM belongs to a group of medicines called antipsychotics. It contains the ingredient ziprasidone.
Ziprasidone is thought to work by correcting the imbalance of some chemicals in the brain. This, in turn, reduces the agitation or aggression caused by the illness.

Zeldox IM is an injection. It is available only in a hospital with a doctor's prescription.
Only a doctor or nurse can give the injection.
Zeldox IM is not recommended for the treatment of elderly patients with dementia-related psychosis.
Zeldox IM is not recommended for use in children under 18 years of age. There is not enough information on its effects in this age group.
