Withdrawal Symptoms & Timelines

Withdrawal length varies by substance and by person. Acute alcohol and benzodiazepine withdrawal typically begins within hours of the last dose and, at its most severe, peaks in the first forty-eight to ninety-six hours. Opioid withdrawal usually begins eight to twenty-four hours after the last dose, peaks in thirty-six to seventy-two hours, and largely resolves within five to ten days. Stimulant withdrawal is primarily psychological and can last one to two weeks acutely. Post-acute withdrawal syndrome, with lingering mood, sleep, and cognitive symptoms, can extend for weeks to months in any of these categories. The Archangel Centers coordinates medical detox with accredited partners when any withdrawal needs medical supervision.

Some withdrawals are medically dangerous. Alcohol and benzodiazepine withdrawal both carry real risks of life-threatening seizures and, in severe cases, delirium, and should never be attempted without medical supervision. Opioid withdrawal is rarely fatal on its own but is intensely uncomfortable and reliably drives relapse without clinical support. Fentanyl withdrawal is similar but more complex and less predictable due to tissue accumulation. Stimulant withdrawal is primarily psychological but can include severe depression and suicidal ideation. Never stop a substance you are physically dependent on without medical guidance first.

Medical detox happens at an accredited inpatient or residential facility, not at our outpatient centers. The Archangel Centers coordinates that placement when any withdrawal needs medical supervision, works with the detox facility to ensure continuity, and then steps you into our outpatient programs in New Jersey and North Carolina for the treatment work that follows. There is no dangerous gap in care.

Medically supervised detox is the safest approach to managing withdrawal from alcohol, benzodiazepines, or opioids. In a supervised setting, approved medications can ease specific symptoms: benzodiazepines for alcohol withdrawal seizure prevention, buprenorphine or methadone for opioid withdrawal, clonidine for cardiovascular opioid symptoms, and supportive care throughout. After stabilization, medication-assisted treatment and therapy address the cravings and underlying causes that follow. The Archangel Centers coordinates the supervised detox and then provides the outpatient care.

Getting through withdrawal is the first step, not the finish. The real work of recovery, addressing the psychological, behavioral, and social factors that drive use, begins after withdrawal is stable. The Archangel Centers steps you from coordinated detox directly into outpatient PHP, IOP, or standard outpatient care in New Jersey or North Carolina, matching the intensity to your clinical needs at that point. Sustained recovery requires sustained support, not a single detox episode.
