About Haldol
Haldol (generic haloperidol) is an injectable antipsychotic medication. Haldol is one of the earlier drugs in this class, referred to as a FGA or “first-generation” antipsychotic medication.
Its uses include treating schizophrenia and also controlling disorders of motor movement or vocal tics as in Tourette’s syndrome.
Haldol comes in intramuscular injectable versions, some to be administered at approximately 4-week intervals, and other versions designed to be taken at intervals ranging from every hour to every 8-12 hours daily.1
Discontinuing/Quitting Haldol
Perhaps surprisingly, the FDA reports that most patients coming off short-term use of Haldol do not exhibit problems during withdrawal.1
Since studies done prior to the approval of Haldol were short (a number of weeks) there is no possible statement the FDA could make on long-term or high-dose users attempting Haldol withdrawal, since apparently it was not studied prior to approval. Researchers and clinicians who have studied Haldol withdrawal have observed the suffering of patients recommend gradual tapering to avoid the severe and debilitating withdrawals summarized above.
PLEASE NOTE: Haldol is NOT FDA approved for elderly patients with dementia-related psychosis, and is contraindicated in patients with Parkinson’s disease. Infants should not be nursed where the mother is taking Haldol, and extreme caution is advised during pregnancy since maternal use in humans and animals featured limb malformations and other birth defects as well as fatality.1,4
Notes on Risks Associated With Antipsychotics
Tardive dyskinesia and cardiovascular adverse events are two notable concerns linked to Haldol, as stated by the FDA and independent research. Between 13% and 24% of patients treated with antipsychotic medications develop tardive dyskinesia.7,9 Elderly patients with dementia-related psychosis should not be treated with Haldol due to the increased risk of cardiac failure and death.1,4,7,8,9 See more on this topic below, where you can find additional information concerning withdrawal symptoms and other important safety topics relating to Haldol.
Note Re Combining CNS Depressants/Alcohol
Haldol should not be combined with other medications or alcohol. Due to the synergistic effect of combining multiple CNS depressants, there is an augmented risk of death from respiratory failure or other potentially fatal risks and severe side effects.6
What Haldol Is Used For
The FDA has given approval for Haldol to treat a variety of conditions.
Haldol is prescribed to treat:
- Tourette’s syndrome
- Schizophrenia*
- Acute psychosis
- Manic episodes in bipolar disorder
- Hallucinations in alcohol withdrawal
- Nausea/vomiting
- Extreme agitation or aggression
*Research shows that although antipsychotic medications are often used to sedate patients with schizophrenia, mania, rage, or other psychiatric symptoms, they introduce the risk of developing tardive dyskinesia, an often irreversible drug-induced condition that may occur even after short-term use.1,7,8,9
Haldol (haloperidol) Alternative Names and Slang
Haldol has not developed a known street presence as a drug of abuse. Haldol is the brand or trade name for the generic drug haloperidol. Another version of the drug named Haldol Decanoate or haloperidol decanoate is a longer-acting form of Haldol, administered intramuscularly. In reference to its use for sedating violent patients, it is sometimes referred to as the Velvet Hammer for its profound and immediate sedative properties.3
Haldol Side Effects
Haldol (haloperidol) is a 1st-generation antipsychotic medication. First-generation antipsychotics such as Haldol are considered to have more severe side effects than the second-generation (later) antipsychotic medications.21
Haldol Side effects can be severe, including:
- Studies show that between 13% and 24% of patients on antipsychotic medications develop tardive dyskinesia.7,9 Tardive dyskinesia, a typically irreversible disorder involving involuntary motor/muscle movements is most often seen in the elderly female population. The duration of treatment with Haldol and the cumulative dosages over time are associated with TD, but the disorder can also present after a relatively brief use of Haldol in treatment. There is no known treatment for tardive dyskinesia, but the condition has sometimes been seen to remit after discontinuation of the medication. Involves involuntary facial tics, grimaces, lip-smacking, tongue rolling, etc.9
- NMS or neuroleptic muscular syndrome is a potentially fatal disorder involving acute renal failure, fever, muscle rigidity, tachycardia, catatonia, stupor, immobility, cardiac dysrhythmias, blood pressure fluctuations, and other symptoms. Should these signs present, the patient should be taken off the medication immediately in a controlled medical setting such as an ICU.1
- Seizures, convulsions 23
- Neurolepsis, a condition involving psychomotor slowing, emotional quieting, and affective indifference (extreme apathy). This might look like slowed or irregular gait, or hypokinesia or Bradykinesia as in Parkinson’s patients, or “masked” face, the inability to make facial expressions, for example.22
- Cardiovascular events resulting in death especially observed in elderly patients with dementia or dementia-related psychosis, low blood pressure.1
- Falls, injuries most often in the elderly population on Haldol, can lead to bone fractures or other types of injuries or accidents.10
- Bronchopneumonia has been observed in cases following the use of Haldol in treatment, and some cases have been fatal.1
- Inability to walk, shuffling, or unsteady gait.11,22
- Inability to talk, slowness in speech.12,22
- Use in pregnancy has been associated with malformations and other birth defects.1,4
- Constipation 23
This is not a complete list but does show the extensive range of potential side effects that can affect virtually every part of the human body. Coupled with a lowered awareness of self and one’s environment, this suggests a person on Haldol needs careful monitoring by an alert and interested medically trained caregiver and should avoid driving or operating heavy machinery.
