This table shows all Adverse Drug Reactions reported to the FDA's Adverse Event Reporting System between 2004 and the 2nd Quarter of 2008 where the listed psychiatric drug was identified as the Primary Suspect Drug (FDA's term) deemed responsible for causing or inducing these reactions and where one or more of the Adverse Reactions reported for the Case described a congenital, prenatal or neonatal condition. Where no Age, Date of Event or Indication (the condition being treated) are shown, none were present in the FDA records.

Reported By: CN-Consumer, LW-Lawyer, MD-Physician, OT-Other Healthcare Provider, PH-Pharmacist, Blank-Not Reported in ISR (Individual Safety Report).

The Oxford English Dictionary defines a poison as "a substance that causes death or harm when introduced into or absorbed by a living organism."  This psychiatric drug fits that definition.

Haloperidol Adverse Reaction Definitions
Abortion Spontaneous	Miscarriage means loss of an embryo or fetus before the 20th week of pregnancy. Most miscarriages occur during the first 14 weeks of pregnancy. The medical term for miscarriage is spontaneous abortion.
Arrhythmia	An arrhythmia is an abnormality in the heart's rhythm, or heartbeat pattern. The heartbeat can be too slow, too fast, have extra beats, skip a beat, or otherwise beat irregularly.
Athrogryposis Multiplex	The permanent fixation of joints in a contracted position. [Images]
Atrial Septal Defect	An atrial septal defect (ASD), a congenital defect, occurs when there is an opening in the atrial septum, or dividing wall between the two upper chambers of the heart, known as the right and left atria. Normally, oxygen-poor (blue) blood returns to the right atrium from the body, travels to the right ventricle, then is pumped into the lungs where it receives oxygen. Oxygen-rich (red) blood returns to the left atrium from the lungs, passes into the left ventricle, then is pumped out to the body through the aorta. An atrial septal defect allows oxygen-rich (red) blood to pass from the left atrium through the opening in the septum, and then mix with oxygen-poor (blue) blood in the right atrium. This heart defect can cause lung problems if not repaired. When blood passes through the ASD from the left atrium to the right atrium, a larger volume of blood than normal must be handled by the right side of the heart, causing the right side to become overworked and enlarged. Extra blood then passes through the pulmonary artery into the lungs, causing higher pressure than normal in the blood vessels in the lungs, a condition known as pulmonary hypertension.
Bradycardia	Slowness of heart rate.
Congenital	A physical abnormality that is present at birth.
Congenital Anomaly	Medical term for a birth defect which is a physical abnormality that is present at birth; they are also called congenital abnormalities. When multiple birth defects occur together and have a similar cause, they are called syndromes (e.g. Drug Withdrawal Syndrome Neonatal).
Drug Withdrawal Syndrome Neonatal	Refers to the characteristic signs and symptoms that appear when a drug that causes physical dependence is regularly used for a long time and then suddenly discontinued or decreased in dosage. Also known as abstinence syndrome. A group of unpleasant symptoms produced by the abrupt termination of drug taking. These symptoms, commonly called withdrawal symptoms, include anxiety, muscle weakness, nausea, vomiting, tremor, and a rapid heart beat.
Dyskinesia	An impairment in the ability to control movements, characterized by spasmodic or repetitive motions or lack of coordination.
Foetal Distress Syndrome	An abnormal condition of a fetus during gestation or at the time of delivery, marked by altered heart rate or rhythm and leading to compromised blood flow or changes in blood chemistry.
Gastroschisis	A congenital fissure (split or crack) in the abdominal wall usually accompanied by protrusion of the viscera (intestines). [Images]
Grand Mal Convusion	A severe form of epilepsy characterized by seizures involving spasms and loss of consciousness.
Hypotonia	Decease of normal tonicity (normal firmness or functional readiness in body tissues or organs) or tension.
Patent Ductus Arteriosus	Patent ductus arteriosus (PDA) is a heart defect that occurs when the ductus arteriosus (the temporary fetal blood vessel that connects the aorta and the pulmonary artery) does not close at birth. Because the placenta does the work of exchanging oxygen and carbon dioxide through the mother's circulation, the fetal lungs are not used for breathing. Instead of blood flowing to the lungs to pick up oxygen and then flowing to the rest of the body, the fetal circulation shunts (bypasses) most of the blood away from the lungs. In the fetus, blood is shunted from the pulmonary artery to the aorta through the ductus arteriosus. However, with the first breaths of air the baby takes at birth, the fetal circulation changes. A larger amount of blood is sent to the lungs to pick up oxygen. Because the ductus arteriosus is no longer needed, it normally begins to wither and close off. In some infants, the ductus arteriosus remains open (or patent) and the resulting heart defect is known as patent ductus arteriosus. The shunting causes too much blood to flow to the lungs and not enough to the other parts of the body. There may be changes in the blood pressure, and the heart may enlarge as it tries to make up for the abnormal blood flow. Babies with PDA may be at risk for infection or inflammation of the arteries. Severe PDA can cause slow growth, and may result in heart failure.
Pierre Robin Syndrome	Pierre Robin Syndrome (PRS) is a congenital condition of facial abnormalities in humans. As PRS is not caused by a single defect gene, it is not a genetic syndrome, but rather a chain of certain developmental malformations, one entailing the next. [Images]
Strabismus	Strabismus is a condition in which the eyes do not point in the same direction. It can also be referred to as a tropia or squint. [Images]
Syndactyly	A congenital anomaly in humans characterized by two or more fused fingers or toes. [Images]
Talipes	Clubfoot is a condition in which one or both feet are twisted into an abnormal position at birth. The condition is also known as talipes. [Images]
Tremor	Tremor is an unintentional (involuntary), rhythmical alternating movement that may affect the muscles of any part of the body. Tremor is caused by the rapid alternating contraction and relaxation of muscles and is a common symptom of diseases of the nervous system (neurologic disease).
Ventricular Septal Defect	A ventricular septal defect is a hole in the wall of the heart (septum) that separates the left lower chamber (left ventricle) from the right lower chamber (right ventricle). The hole allows blood to flow from the left ventricle to the right ventricle instead of entering the aorta for distribution throughout the body. This blood recycles through the lungs before returning to the left ventricle. This results in less oxygenated blood reaching the body. If the hole is sufficiently large, the lack of oxygen being delivered to the body can cause severe problems, including heart failure and breathlessness.

MedWatch is the Food and Drug Administration's program for reporting any undesirable experience associated with the use of a medical product. If you think you or someone in your family has experienced an adverse reaction from taking Haloperidol and it has not been reported to the FDA, see this page for instructions on reporting the adverse event through your doctor or directly to the FDA using an online form.

A May 2006 USA Today article states that "drug companies are required to file any reports they have to the FDA, but consumers and doctors report such events on a voluntary basis. Studies suggest the FDA's Adverse Events Reporting System database captures only 1% to 10% of drug-induced side effects and deaths, "maybe even less than 1%," says clinical pharmacologist Alastair J.J. Wood, an associate dean at Vanderbilt Medical School in Nashville. So the real number of cases is almost certainly much higher".
