If you cannot reach a qualified professional by telephone to discuss the overdose, it would be prudent for you to take the overdosed person to the nearest hospital's Emergency Department or medical facility. Each person responds differently, and reactions are hard to predict. Many people who are directed to go to the Emergency Department may not develop any physical signs of poisoning. Others will become quite ill. You may call 911 for these services.
Family members are also often helpful in persuading the person to seek medical care.
Anyone who is with a person who overdoses on drugs can assist by finding all medication containers and bringing them to the Emergency Department physician. The doctor will order laboratory tests based on the organ systems that can be harmed by the specific drug overdose. Family members and associates are an important source of information. They can assist in providing the physician with names of drugs, amounts taken, and timing of overdose. Specific drug levels in the blood may be measured, depending on the drug taken and the reason for the overdose.
