1. What is Haloperidol Prodes and what is it used for

The name of this medicine is Haloperidol Prodes.

Haloperidol Prodes contains the active substance haloperidol, which belongs to a group of medicines called “antipsychotics”.

Haloperidol Prodes is used in adult, adolescent, and child patients to treat diseases that affect the way of thinking, feeling, or behaving. These include mental health problems (such as schizophrenia and bipolar disorder) and behavioral problems.

These diseases can cause the patient to:

• Feel confused (confusional syndrome).
• See, hear, feel, or smell things that are not real (hallucinations).
• Believe things that are not true (delusions).
• Become extremely suspicious (paranoia).
• Feel very excited, agitated, emotional, impulsive, or hyperactive.
• Become very aggressive, hostile, or violent.

In adolescents and children, Haloperidol Prodes is used to treat schizophrenia in patients aged 13 to 17 years, and to treat behavioral problems in patients aged 6 to 17 years.

Haloperidol Prodes is also used:

• In adolescents and children aged 10 to 17 years, and in adults to treat movements or sounds that the patient cannot control (tics), such as in severe Tourette's syndrome.
• In adults, to help control movements in Huntington's disease.

Haloperidol Prodes is sometimes used when other medicines or treatments have not worked or have caused unacceptable side effects.
