Here are some key points about Haloperidol:

  • Indications: Medicine is commonly prescribed to treat symptoms of schizophrenia, such as hallucinations (seeing or hearing things that are not there), delusions (false beliefs), disorganized thinking, and emotional withdrawal. It may also be used to manage severe behavioral problems or agitation in individuals with certain mental health conditions.
  • Mode of action: Haloperidol works by blocking the dopamine receptors in the brain, which helps to reduce the overactivity of dopamine and alleviate symptoms associated with psychosis.

How to use

Here are some general guidelines on how to use Haloperidol:

  1. Use the correct formulation: Medicine is available in various formulations, including tablets, liquid, and injections. Ensure that you are using the prescribed formulation and follow the instructions for its use.
  2. Swallow tablets whole: If you are taking Haloperidol in tablet form, swallow the tablet whole with a glass of water. Do not crush, break, or chew the tablet unless specifically instructed to do so.
  3. Measure liquid medication accurately: If you are using the liquid form of Haldol, use a measuring device such as a dosing spoon or oral syringe to measure the correct amount. Do not use a household spoon as it may not provide accurate measurements.
  4. Be consistent with the timing: Try to take Haloperidol at the same time(s) each day to maintain a consistent level of the medication in your system. This can help optimize its effectiveness in managing your symptoms.


The dosage of Haloperidol prescribed to an individual can vary depending on various factors, including the condition being treated, the severity of symptoms, age, and individual response to the medication. The following are some general dosage guidelines:

Schizophrenia and Other Psychotic Disorders:

  • Starting Dose: The usual starting dose for adults is 0.5 to 2 mg taken once or twice daily.
  • Maintenance Dose: The maintenance dose can range from 1 to 15 mg per day, divided into multiple doses.
  • Maximum Dose: In some cases, higher doses up to 100 mg per day may be prescribed, but this is less common.

Severe Behavioral Problems or Agitation:

  • Starting Dose: The starting dose for adults is typically 0.5 to 2 mg taken once or twice daily.
  • Maintenance Dose: The maintenance dose can range from 0.5 to 100 mg per day, divided into multiple doses.
  • Maximum Dose: Higher doses up to 100 mg per day may be used in certain cases.

Elderly Patients:

  • Elderly individuals may require lower doses of Haloperidol due to increased sensitivity to the medication and higher risk of side effects. The starting dose is often reduced, and the dosage is adjusted based on the individual's response.

Side effects

The following are some common side effects associated with Haloperidol:

Extrapyramidal Symptoms (EPS): These are movement disorders that can include:

  • Muscle stiffness
  • Tremors
  • Restlessness
  • Akathisia (a feeling of inner restlessness)
  • Parkinsonism-like symptoms (slowed movements, rigidity)
  • Tardive dyskinesia (involuntary movements of the face or body)

Sedation: Haloperidol can cause drowsiness or sedation, which may affect your ability to concentrate or perform certain activities. It is important to avoid driving or operating machinery if you experience significant sedation.

Orthostatic Hypotension: This is a drop in blood pressure upon standing up, which can cause dizziness or lightheadedness. It is important to rise slowly from a sitting or lying position to minimize the risk of orthostatic hypotension.

Anticholinergic Effects: Haloperidol can have anticholinergic effects, leading to:

  • Dry mouth
  • Blurred vision
  • Constipation
  • Urinary retention

Metabolic Effects: Haloperidol may cause metabolic changes, such as:

  • Weight gain
  • Increased appetite
  • Increased blood sugar levels
  • Elevated cholesterol or triglyceride levels

Cardiovascular Effects: Rarely, Haloperidol can affect heart rhythm, leading to irregular heartbeat (arrhythmia). It is important to seek medical attention if you experience palpitations, chest pain, or fainting.

Neuroleptic Malignant Syndrome (NMS): This is a rare but potentially life-threatening condition that can occur with the use of antipsychotic medications, including Haldol. Symptoms may include fever, muscle stiffness, confusion, and changes in blood pressure and heart rate. NMS requires immediate medical attention.


When it comes to storing Haloperidol, it is essential to follow the recommended guidelines to ensure the medication remains safe and effective. Here are some general storage instructions:

  1. Store at room temperature: Haloperidol should be stored at room temperature, typically between 20°C to 25°C (68°F to 77°F). Avoid exposing the medication to excessive heat or cold, such as direct sunlight, extreme temperatures, or humidity.
  2. Keep in its original packaging: Keep tablets in its original packaging, such as the blister pack or bottle, to protect it from light and moisture. The packaging is designed to provide an additional barrier to maintain the quality of the medication.
  3. Keep away from children and pets: Store Haloperidol in a secure location that is out of reach of children and pets. Consider using childproof containers or storing it in a locked cabinet or drawer.
  4. Do not transfer to different containers: It is recommended to keep medicament in its original container. Avoid transferring the medication to different containers, as this can lead to confusion or accidental ingestion by others.
  5. Check for expiry date: Before using Haloperidol, check the expiration date on the packaging. Do not use the medication if it has expired. Properly dispose of any expired or unused medication following local guidelines or consult with your pharmacist for proper disposal methods.
  6. Avoid bathroom storage: Avoid storing Haloperidol in the bathroom or other areas with high humidity, as moisture can degrade the medication. The bathroom is typically humid due to showers and baths, making it unsuitable for medication storage.

It is important to note that specific storage instructions may vary depending on the formulation and brand of Haloperidol. Always refer to the packaging or consult with your pharmacist for any specific storage requirements provided by the manufacturer.


Overdosing on Haldol can be serious and potentially life-threatening. If you suspect an overdose or have taken more than the prescribed dose of Haloperidol, it is crucial to seek immediate medical attention or contact your local emergency services. Here are some general information and measures regarding overdose:

  1. Recognizing symptoms: An overdose of Haloperidol may exhibit symptoms such as extreme drowsiness, confusion, agitation, hallucinations, muscle stiffness, tremors, rapid heartbeat, low blood pressure, fainting, and difficulty breathing.
  2. Contact emergency services: Call your local emergency number or go to the nearest emergency room immediately if you or someone you know has overdosed on Haloperidol. Prompt medical attention is essential to manage the overdose effectively.
  3. Do not induce vomiting: Do not try to induce vomiting unless specifically instructed to do so by medical professionals. They will determine the most appropriate course of action based on the situation.
  4. Supportive care: Treatment may involve supportive measures such as ensuring adequate oxygen supply, maintaining hydration, and managing any complications or symptoms that arise as a result of the overdose.

If you or someone you know has taken an overdose of Haloperidol, do not delay seeking immediate medical attention. Contact emergency services or go to the nearest emergency room as soon as possible.

Missed Doses

If you miss a dose of Haloperidol, it is important to take it as soon as you remember. However, if it is close to the time for your next scheduled dose, skip the missed dose and continue with your regular dosing schedule. Do not take a double dose to make up for the missed one.

It is important to follow the prescribed dosing schedule for this medicine to maintain a consistent level of the medication in your body. Missing a dose may lead to a fluctuation in blood levels of Haloperidol, which can affect the effectiveness of the treatment.
