For adults with psychosis or Tourette's syndrome, the usual starting dose of oral (taken by mouth) haloperidol ranges from 2 mg to 6 mg per day in 1 to 2 divided doses. Your doctor may gradually increase the dose to determine the most appropriate dose for you. Dosing depends on your age and needs and how well you tolerate the medication.
Seniors may require a lower starting dose, usually 0.25 mg to 0.5 mg taken 2 or 3 times a day.
For children 6 to 12 years old, the usual starting dose of oral haloperidol ranges from 0.25 mg to 0.5 mg taken 2 to 3 times a day. The doctor may recommend gradually increasing the dose and will determine the most appropriate dose. Dosing depends on how well the medication works for the child and how well it is tolerated. Haloperidol tablets should be taken with food or milk to avoid stomach upset.
Intramuscular injections of haloperidol can also be given to people with an acute psychotic attack or who are agitated or aggressive. For the ongoing treatment of psychiatric disorders, long-acting haloperidol injections are used to help decrease the number of pills some people have to take. The starting dose of the injection depends on the dose of oral haloperidol the person was previously taking. The long-acting injection is given intramuscularly (into a muscle), usually by a doctor or nurse, every 4 weeks. For some people who start using the long-acting injection, they may be taking both the oral and injection forms of haloperidol at the same time.
Many things can affect the dose of a medication that a person needs, such as body weight, other medical conditions, and other medications.

Do not use Teva Haloperidol if you:
There may be an interaction between haloperidol and any of the following:
If you are taking any of these medications, speak with your doctor or pharmacist. Depending on your specific circumstances, your doctor may want you to:
An interaction between two medications does not always mean that you must stop taking one of them. Speak to your doctor about how any drug interactions are being managed or should be managed.
Medications other than those listed above may interact with Teva Haloperidol. Tell your doctor or prescriber about all prescription, over-the-counter (non-prescription), and herbal medications you are taking. Also tell them about any supplements you take. Since caffeine, alcohol, the Nicotine from cigarettes, or street drugs can affect the action of many medications, you should let your prescriber know if you use them.
Before you begin using a medication, be sure to inform your doctor of any medical conditions or Allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use Teva Haloperidol.
Body temperature: Teva Haloperidol, like other antipsychotic medications, can disrupt the body's ability to control body temperature. People who exercise vigorously, who are exposed to extreme heat, are dehydrated, or are taking anticholinergic medications (e.g., Benztropine, Oxybutynin) are more at risk. Contact your doctor as soon as possible if you feel very hot and are unable to cool down.
Blood Clots: Haloperidol has been associated with blood clots in the legs and lungs. If you experience unusual pain, heat, or swelling in one leg or sudden difficulty breathing and chest pain, get immediate medical help.
Blood counts: Teva Haloperidol can decrease the number of neutrophils (a type of white blood cell that helps fight infection), red blood cells (which carry oxygen), and platelets (which help your blood to clot). Your doctor will do blood tests to monitor this. If you notice any signs of infection (e.g., fever, chills, or sore throat) or unusual bleeding or bruising, contact your doctor immediately.
Blood sugar: Haloperidol may cause an increase in blood sugar levels (may cause a loss of blood glucose control) and glucose tolerance may change. This may happen to people who have never had high blood glucose levels. People with Diabetes may find it necessary to monitor their blood sugar more frequently while using Teva Haloperidol.
If you have diabetes or are at risk for developing diabetes, discuss with your doctor how Teva Haloperidol may affect your medical condition, how your medical condition may affect the dosing and effectiveness of Teva Haloperidol, and whether any special monitoring is needed.
Cardiovascular effects: Cases of sudden death or altered heartbeats (torsade de pointes) have been reported by people receiving haloperidol, especially at higher than recommended doses of any formulation. If you have a heart condition called QT prolongation and electrolyte imbalances (especially potassium and magnesium) or are taking other medications that are associated with QT prolongation you should discuss with your doctor how Teva Haloperidol may affect your medical condition, how your medical condition may affect the dosing and effectiveness of Teva Haloperidol, and whether any special monitoring is needed.
Dizziness when standing up: Haloperidol can cause dizziness, especially when standing from a sitting or lying position. If you have cardiovascular disease, diabetes, or are a senior, discuss with your doctor how Teva Haloperidol may affect your medical condition, how your medical condition may affect the dosing and effectiveness of Teva Haloperidol, and whether any special monitoring is needed, since you may be more likely to experience this side effect.
Drowsiness/reduced alertness: Haloperidol may affect the mental or physical abilities needed to drive or operate machinery, particularly when you first start taking the medication or increase your dose. Avoid driving, operating machinery, or performing other hazardous tasks until you have determined how Teva Haloperidol affects you.
Hyperthyroidism: If you have uncontrolled high Thyroid disease (hyperthyroidism), discuss with your doctor how Teva Haloperidol may affect your medical condition, how your medical condition may affect the dosing and effectiveness of Teva Haloperidol, and whether any special monitoring is needed.
Kidney function: If you have decreased kidney function or Kidney Disease, discuss with your doctor how Teva Haloperidol may affect your medical condition, how your medical condition may affect the dosing and effectiveness of Teva Haloperidol, and whether any special monitoring is needed.
Liver function: If you have decreased liver function or liver disease, discuss with your doctor how Teva Haloperidol may affect your medical condition, how your medical condition may affect the dosing and effectiveness of Teva Haloperidol, and whether any special monitoring is needed.
Movement disorders: The use of haloperidol has been associated with a potentially irreversible movement disorder called tardive dyskinesia (TD). This syndrome involves the involuntary movements of facial muscles and the tongue. The risk of a person developing this syndrome is usually but not always linked to treatment duration and the total amount of antipsychotic medications taken.
If you develop signs and symptoms of TD during treatment with haloperidol, including sticking the tongue out, smacking the lips, pursing or puckering of lips, and blinking eyes rapidly, contact your doctor as soon as possible.
Neuroleptic malignant syndrome (NMS): Haloperidol, like other antipsychotic medications, can cause a potentially fatal syndrome known as neuroleptic malignant syndrome (NMS). If you notice the symptoms of NMS such as high fever; muscle stiffness; confusion or loss of consciousness; sweating; racing, or irregular heartbeat; or fainting; get immediate medical attention.
Prolonged erection (priapism): If an erection lasts longer than 4 hours (a rare occurrence), seek immediate medical assistance. If this condition is not treated quickly, tissue damage and permanent loss of the ability to have an erection could result.
Seizure disorders: Haloperidol may increase the frequency of seizures. If you have a seizure disorder or a history of drug- or medication-induced seizures, abnormal EEG, or head trauma, discuss with your doctor how Teva Haloperidol may affect your medical condition, how your medical condition may affect the dosing and effectiveness of Teva Haloperidol, and whether any special monitoring is needed.
Stopping the medication: If Teva Haloperidol needs to be stopped, it should be done gradually, under the supervision of your doctor. If you suddenly stop taking Teva Haloperidol, you may experience symptoms of withdrawal.
Take the medication exactly as prescribed by your doctor, and do not stop taking the medication without checking with your doctor first.
Pregnancy: Teva Haloperidol should not be used during pregnancy unless the benefits outweigh the risks. If you become pregnant while taking Teva Haloperidol, contact your doctor immediately.

Children: The safety and effectiveness of using Teva Haloperidol have not been established for young children.
Seniors: Seniors taking Teva Haloperidol may be more likely to develop side effects from haloperidol, especially fatigue and a decreased ability to sense thirst. Seniors taking haloperidol should ensure that they drink enough fluids to remain hydrated.
There may be a higher risk of strokes, mental decline and deaths associated with the use of haloperidol by elderly people with Dementia. Talk to your doctor about the risks and benefits of using Teva Haloperidol.
