Fentanyl Withdrawal Timeline
The fentanyl withdrawal timeline varies from person to person, but typically, symptoms emerge within hours to a day after the last dose. Initially, individuals may notice mild signs like yawning, teary eyes, and muscle aches.
As time progresses, withdrawal symptoms peak within 2–3 days. During this peak period, individuals often endure intense physical discomfort, resembling flu-like symptoms such as nausea, vomiting, diarrhea, sweating, and chills. They may also confront severe muscle and bone pain, insomnia, anxiety, agitation, mood swings, and elevated heart rate and blood pressure. These symptoms can be distressing and difficult to manage without medical intervention.
Although the acute phase of fentanyl withdrawal usually lasts about a week, some symptoms may persist for weeks or even months, especially psychological issues like anxiety disorder and depression. Various factors, including the duration of fentanyl use, dosage, individual metabolism, and overall health, influence the duration and severity of withdrawal symptoms. Seeking medical support and supervision is crucial during the withdrawal process to ensure safety and provide effective symptom management.
