Signs and symptoms of narcotic withdrawal: The withdrawal syndrome from narcotics generally includes signs and symptoms opposite of the drug's intended medical effects. The severity of the withdrawal syndrome increases as the drug dose increases. The longer the duration of the physical dependence to the narcotic increases, the more severe the withdrawal syndrome. Symptoms of heroin withdrawal generally appear 12-14 hours after the last dose. Symptoms of methadone withdrawal appear 24-36 hours after the last dose. Heroin withdrawal peaks within 36-72 hours and may last seven to 14 days. Methadone withdrawal peaks at three to five days and may last three to four weeks. Although uncomfortable, acute narcotic withdrawal for adults is not considered life-threatening unless the person has a medical condition that compromises their health (for example, if someone has severe heart disease).
