Combined drug intoxication (CDI), also known as multiple drug intake (MDI) or lethal polydrug/polypharmacy intoxication, is an unnatural cause of human death. CDI is often confused with drug overdose, but it is a completely different phenomenon. It is distinct in that it is due to the simultaneous use of multiple drugs, whether the drugs are prescription, over-the-counter, recreational, or some other combination. Alcohol can exacerbate the symptoms and may directly contribute to increased severity of symptoms. The reasons for toxicity vary depending on the mixture of drugs. Usually, most victims die after using two or more drugs in combination that suppress breathing, and the low blood oxygen level causes brain death.

The CDI/MDI phenomenon seems to be becoming more common in recent years. In December 2007, according to Dr. John Mendelson, a pharmacologist at the California Pacific Medical Center Research Institute, deaths by combined drug intoxication were relatively "rare" ("one in several million"), though they appeared then to be "on the rise". In July 2008, the Associated Press and CNN reported on a medical study showing that over two decades, from 1983 to 2004, such deaths have soared. It has also become a prevalent risk for older patients.

Risk factors

People who engage in polypharmacy and other hypochondriac behaviors are at an elevated risk of death from CDI. Elderly people are at the highest risk of CDI, because of having many age-related health problems requiring many medications combined with age-impaired judgment, leading to confusion in taking medications.

Prevention

In general, the simultaneous use of multiple drugs should be carefully monitored by a qualified individual such as board certified and licensed medical doctor, either an MD or DO Close association between prescribing physicians and pharmacies, along with the computerization of prescriptions and patients' medical histories, aim to avoid the occurrence of dangerous drug interactions. Lists of contraindications for a drug are usually provided with it, either in monographs, package inserts (accompanying prescribed medications), or in warning labels (for OTC drugs). CDI/MDI might also be avoided by physicians requiring their patients to return any unused prescriptions. Patients should ask their doctors and pharmacists if there are any interactions between the drugs they are taking.

Acetaminophen/paracetamol deaths

On June 30, 2009, an FDA advisory panel recommended that Vicodin and another painkiller, Percocet, be removed from the market because they have allegedly caused over 400 deaths a year. The problem is with paracetamol (acetaminophen/Tylenol for example ) overdose and liver damage. These two drugs, in combination with other drugs like Nyquil and Theraflu, can cause death by multiple drug intake and/or drug overdose. Another solution would be to not include paracetamol with Vicodin or Percocet.

Speedball deaths

Some speedball deaths that are diagnosed as MDI/CDI might simply be drug overdose, which is a related but completely different phenomenon. The following list is for speedball CDI/MDI deaths only. Any combination of uppers and a downers can be called a speedball death.

Karen Ann Quinlan

The Right to Die case of then-comatose Karen Ann Quinlan (March 29, 1954 – June 11, 1985) made legal history in 1975 and 1976, stimulating public scrutiny of ethical and moral implications of her case. In 1975, after drinking gin and tonics at a party and then taking Diazepam, Quinlan collapsed, suffered respiratory failure and irreversible brain damage, and, after being taken to the hospital, lapsed into a persistent vegetative state. After she had been kept alive on a ventilator for several months without improvement, her parents requested that the hospital discontinue such active care and allow her to die. The hospital refused, and the subsequent legal battles made newspaper headlines and set significant precedents. After the New Jersey Supreme Court ruled in her parents' favor, Quinlan spent nine more years comatose in the hospital, before dying from pneumonia in 1985.

Michael Jackson

The CDI/MDI death of Michael Jackson led to the trial of Conrad Murray, whose license was revoked in four states and who was sentenced to serve four years in a California prison.
