The Haldol Injection consists of a major antipsychotic called haloperidol. We carry the generic alternative to this medication is 5mg/ml!

This injection is used most commonly to treat schizophrenia and the symptoms it consists of. This is a mental illness disorder that produces unusual or disturbed thoughts, with little interest in living life while also being overwhelmed with strong or inappropriate emotions. A person with schizophrenia may have thoughts of suicide and self harm or may have aggression and want to harm others.

Additionally, the Haldol Injection may be used to manage uncontrollable body movements and verbal words and sounds in those who suffer Tourette’s syndrome.

Haloperidol is effective in the treatment of certain mental and mood disorders due to its ability to block the dopamine in the brain and enhance its turnover rate, reducing the amount of abnormal excitement in the brain.

Your doctor will determine your dose based on your age, severity of the disorder, previous response to antipsychotic medications, and interacting medications or conditions.
