Opioid withdrawal syndrome
Symptoms appear gradually during the first hours of withdrawal and remain for several days. Most symptoms resolve within 10 days. Use of narcotic antagonists (naloxone) can quickly induce symptoms of opioid withdrawal. Onset of symptoms and their severity depend in part on the properties of the particular opioid drug being used, such as its half-life. Two to three times the half-life of the withdrawn opioid is often used as a rough estimate of time to symptom onset.
Opiates can be derived naturally from poppy plants or produced via semi-synthetic or synthetic methods. Examples include morphine and codeine (natural opiates); heroin, oxycodone, oxymorphone, hydrocodone, hydromorphone, and buprenorphine (semi-synthetic opioids); and meperidine (Demerol), fentanyl, and methadone (synthetic opioids). Short-acting opioids include heroin and morphine, while methadone is a long-acting opioid.
Opioid withdrawal syndrome is rarely life threatening or likely to cause significant alterations in mental status. However, physical discomfort coupled with intense craving make it difficult for many patients to complete withdrawal treatment, which is often the required first step of long-term treatment such as residential rehabilitation. Due to the risk of inducing a precipitous withdrawal, some treatment options, such as opioid receptor antagonists, are prescribed only after patients have successfully completed medically supervised withdrawal. Devices with cranial nerve stimulation may also help reduce symptoms of acute opioid withdrawal.
Research is ongoing to continue developing effective temporizing measures as a bridge to the initiation of definitive medication-assisted therapy. As with any addictive disease, risk of relapse is overall high, particularly when strong support networks and abstinence efforts are not pursued.
