Haloperidol
Summary
Haloperidol is used to treat schizophrenia, which is a mental health condition affecting mood and behavior, and acute psychosis, which involves a loss of contact with reality. It also helps control tics and vocal outbursts in Tourette's syndrome, which is a disorder characterized by repetitive movements or sounds.
Haloperidol works by blocking dopamine receptors, which are parts of the brain that respond to dopamine, a chemical affecting mood and behavior. By blocking these receptors, Haloperidol helps reduce symptoms like hallucinations and delusions, which are false beliefs or perceptions, improving overall mental health.
The usual starting dose for adults is 0.5 mg to 2 mg taken two or three times a day. The maximum recommended dose is typically 20 mg per day. Haloperidol is taken orally, which means by mouth, and should be swallowed whole without crushing or chewing.
Common side effects of Haloperidol include drowsiness, which means feeling sleepy, dizziness, which is a sensation of spinning, and dry mouth, which is a lack of saliva. These effects can vary from person to person and are usually mild to moderate.
Haloperidol should not be used if you have severe heart problems like QT prolongation, which affects heart rhythm, or Parkinson's disease, which is a movement disorder. It can interact with other medications, increasing side effects, so always inform your doctor about all medications you take.
