Fentanyl withdrawal has a reputation for being brutal, and people who have been through it tend to confirm that. Most of that fear is about the unknown: how long it lasts, how bad it gets, and whether it is safe to do at home. This post lays out what the first two weeks generally look like, why going through it alone is a risky plan, and what is different about withdrawal in Massachusetts right now.
One note first. Everyone’s timeline is different. It depends on how much fentanyl was being used, for how long, what else was in the mix, and the person’s health. What follows is a general picture, and a doctor’s guidance should replace it for any specific situation.
What Withdrawal Feels Like
MedlinePlus describes opioid withdrawal in two phases. Early symptoms include agitation, anxiety, muscle aches, a runny nose, watery eyes, sweating, yawning, and trouble sleeping. Later symptoms include abdominal cramping, diarrhea, nausea, vomiting, dilated pupils, and goosebumps. MedlinePlus notes that these symptoms are very uncomfortable but are not generally life threatening in themselves. That is different from alcohol withdrawal, which can cause seizures.
The danger with opioid withdrawal is less about the symptoms and more about what they lead to. Vomiting and diarrhea can cause dehydration. And the misery of it drives many people straight back to using, at a point when tolerance has dropped and a former dose can cause an overdose.
The First Two Weeks, Roughly
The exact timing depends on how much was used, for how long, and what else was in the mix, so these stages are a rough guide only.
- Days one to three: Symptoms often begin within about a day of the last use. Anxiety, aches, sweating, and restlessness build quickly. Sleep is poor or absent.
- Days three to seven: This is usually the hardest stretch. Cramping, nausea, diarrhea, and deep fatigue come along with intense cravings.
- Days seven to fourteen: The physical symptoms generally ease. Sleep stays unsettled, energy is low, and mood can be flat, irritable, or anxious.
After the first two weeks, many people continue to experience low mood, poor sleep, and cravings for weeks or longer. This is the part that gets underestimated. Getting through the physical stage is not the same as being past the risk of returning to use.
Why It Should Not Be Done Alone
There are three reasons to avoid riding it out alone. First, the risk of overdose after withdrawal is real, because tolerance falls quickly. Second, there are medications that make withdrawal much more manageable. MedlinePlus lists methadone and buprenorphine as treatments that ease withdrawal, and clonidine as a way to reduce anxiety, aches, sweating, and cramping. Third, people who go through it without support often do not have a plan for what comes after.
A doctor can talk through options and rule out other medical problems. If you are in Massachusetts, the Massachusetts Substance Use Helpline offers free, confidential support around the clock. You can call or text HOPE to (800) 327-5050.
A Note About Xylazine in the Massachusetts Supply
The Massachusetts Department of Public Health has reported that xylazine, a veterinary sedative, has been found in an increasing number of street drug samples in the state, and it has appeared in opioid overdose deaths. Its presence changes the picture in several ways.
- It is linked to skin wounds and ulcers that can be painful and slow to heal and may need medical attention
- Withdrawal may include irritability, anxiety, restlessness, and high blood pressure alongside the usual opioid symptoms
- Naloxone does not reverse xylazine. It still reverses the opioid, and it should be given in any suspected overdose, but the person may remain sedated and need supportive care and emergency help
Anyone who has been using fentanyl in Massachusetts may have been exposed to xylazine without knowing it, which is another reason to involve a doctor early.
Signs That Need Emergency Care
Call 911 for any overdose signs, such as unresponsiveness, very slow or stopped breathing, or blue or gray lips. For withdrawal, get urgent medical help for repeated vomiting that prevents drinking fluids, signs of dehydration, chest pain, confusion, or thoughts of self-harm. For thoughts of suicide, call or text 988.
What Comes After the First Two Weeks
Withdrawal management gets a person through the physical part. It does not change why the use started or what will happen the first time stress, a bad day, or an old contact shows up. Long-term support, whether that is counseling, peer groups, medication, or structured treatment, is what carries the work forward. MedlinePlus notes that people coming off opioids should also be screened for depression and other mental health conditions, since treating those lowers the risk of going back.
For men on Cape Cod, Foundations at the Miller House offers residential fentanyl addiction treatment for men on Cape Cod. If you are not sure what the right level of care is, or you are not sure whether you need medical withdrawal care first, a conversation with a doctor or a treatment professional is a reasonable place to start.
