Fentanyl has made opioid use far more dangerous. It’s powerful, it shows up in pills and powders sold as other drugs, and a tiny amount can stop someone’s breathing. The good news is that effective treatment exists and works.
Pinpoint pupils, slow or no breathing, blue or gray lips, and not waking up. Give naloxone (Narcan) if you have it, keep them on their side and stay with them. Florida’s 911 Good Samaritan law protects people who call for help during an overdose.
Signs of opioid addiction
- Needing more to get the same effect, or running out of prescriptions early
- Withdrawal when it wears off: yawning, runny nose, sweating, aches, stomach cramps, diarrhea, anxiety
- Small pupils, nodding off, slurred speech or constricted breathing while using
- Doctor shopping, buying pills from friends or the street, or switching to powder
- Money missing, secrecy and pulling away from family
What opioid withdrawal is like
Opioid withdrawal is rarely deadly on its own, but it’s miserable, and that misery drives people back to using. Here’s the usual course for short-acting opioids like heroin and fentanyl:
- 8–24 hoursEarly symptoms
Anxiety, yawning, sweating, runny nose and watery eyes, restlessness.
- 1–3 daysPeak
Muscle aches, chills, stomach cramps, vomiting, diarrhea, intense cravings.
- 4–7 daysEasing
Physical symptoms fade, though fentanyl withdrawal can run longer.
- WeeksLingering
Poor sleep, low mood and cravings can last. This is when relapse risk is highest.
Starting buprenorphine after fentanyl takes some care, because starting too soon can trigger sudden, severe withdrawal. Experienced clinicians now use low-dose starts to avoid that. It’s a good reason to start with a doctor rather than on your own.
Medication is the standard of care
Medication for opioid use disorder (MOUD) cuts the risk of overdose death, keeps people in treatment and makes everything else possible. Three medications are FDA-approved:
| Medication | What it does | Where you get it |
|---|---|---|
| Buprenorphine (Suboxone, Sublocade) | Stops withdrawal and cravings with a ceiling effect that makes overdose less likely | Doctor’s office, clinic or telehealth; daily film or monthly injection |
| Methadone | Long-acting medication that stops withdrawal and cravings | Licensed opioid treatment programs, usually daily at first |
| Naltrexone (Vivitrol) | Blocks the effect of opioids; no high and no dependence | Monthly injection after you’re fully detoxed (7–10 days opioid-free) |
Medication works best with counseling and support, and many people stay on it for a year or longer. Read more about medication-assisted treatment.
Levels of care for opioid addiction
Many people start medication in an outpatient clinic and never need a residential stay. Others need medical detox and a structured program first, especially when they also use benzodiazepines or alcohol, or when home isn’t safe.
Staying safe until treatment starts
- Carry naloxone. Narcan nasal spray is sold over the counter at Florida pharmacies, and many community programs give it out free.
- Never use alone. If you do, call the Never Use Alone line at 1‑800‑484‑3731 so someone can send help if you stop responding.
- Assume pills and powders contain fentanyl. Pills that look like oxycodone or Xanax are often counterfeit.
- Be careful after a break. Tolerance drops fast after detox, the hospital or jail.

Questions people ask us.
Don’t see yours? Call or text (305) 701‑0439. There are no wrong questions, and nothing you tell us leaves the call.
Is Suboxone just replacing one drug with another?
No. Buprenorphine (the main ingredient in Suboxone) is a prescribed medication taken at a steady dose. It stops withdrawal and cravings without the highs and crashes, so people can work, parent and recover. It lowers the risk of dying from an overdose.
How long does fentanyl withdrawal last?
Symptoms usually start within a day of last use, peak in the first few days and ease over about a week. With fentanyl, symptoms can last longer and be less predictable. Medication makes withdrawal far more bearable.
Why is the time after detox so dangerous?
Tolerance drops quickly. If someone relapses at their old dose after detox or jail, the risk of a fatal overdose is much higher. That’s one reason medication and a plan for after detox matter so much.
Can I get buprenorphine without going inpatient?
Yes. Since 2023, any clinician with a standard DEA registration can prescribe buprenorphine, and many outpatient clinics and telehealth providers start people on it. We can help you find one that takes your insurance.
