What fentanyl is

Fentanyl is a synthetic (lab-made) opioid. The CDC explains that there are two types: pharmaceutical fentanyl, which doctors use for surgery or severe pain, and illegally made fentanyl, which causes most fentanyl overdoses.

The National Institute on Drug Abuse (NIDA) says fentanyl is 50 to 100 times more potent than morphine, so even small amounts can be fatal. The CDC adds that illegally made fentanyl is often pressed into fake pills that look like oxycodone or Xanax, or mixed into heroin, cocaine and methamphetamine. Many people don’t know their drugs contain it.

Signs a family may notice

Changes you might see

  • Pulling away from family, friends or work
  • Money or valuables going missing
  • Pills that don’t come from a pharmacy, or foil, straws or burnt spoons
  • Nodding off at odd times, or very small pupils

Signs of withdrawal

  • Muscle aches and stomach cramps
  • Anxiety, agitation and trouble sleeping
  • Nausea, vomiting, diarrhea or chills
  • Strong cravings that drive them back to use

Signs of an opioid overdose include not waking up, slow or shallow breathing, purplish lips or nails and pinpoint pupils. Call 911 and give naloxone if you have it.

Why medical help matters, especially after detox

Opioid withdrawal is very hard to push through alone, and the cravings can pull a person back fast. Medical care makes withdrawal more bearable and connects your loved one to ongoing treatment.

There is a second, quieter danger. When a person stops using, their tolerance drops. NIDA notes that overdoses are more common when someone returns to use after a period without it, because of that loss of tolerance. This is why a few days of detox on its own isn’t enough. The days and weeks after detox, or after leaving jail or a hospital, are a high-risk time.

Medication-assisted treatment (MAT)

NIDA calls medication the standard of care for opioid use disorder. The FDA-approved medications are methadone, buprenorphine and naltrexone. NIDA says research shows these medications can reduce the risk of return to use and of overdose death, and help people stay in treatment.

SAMHSA describes medication combined with counseling as a “whole-patient” approach. Buprenorphine can be prescribed in a doctor’s office. Methadone is given through opioid treatment programs. Read our medication-assisted treatment guide for how this works in Jacksonville.

Keep naloxone close

Naloxone (Narcan) reverses an opioid overdose, including one from fentanyl, according to the CDC. The FDA approved Narcan nasal spray for over-the-counter sale in March 2023, so you can buy it without a prescription. In Florida, free kits are also available. See free naloxone in Jacksonville.

Fentanyl and opioid treatment: common questions

Is medication for opioid use disorder just swapping one drug for another?

No. NIDA calls medication the standard of care, and SAMHSA says these medications do not just substitute one drug for another. Taken as prescribed, they help normalize brain chemistry and reduce cravings so a person can rebuild their life.

How long do people stay on MAT?

It is different for each person. SAMHSA says these medications are safe for long-term use, from months to a lifetime. The doctor and patient decide together.

Can fentanyl be in drugs that aren’t opioids?

Yes. The CDC says powdered fentanyl can be mixed into cocaine and methamphetamine, and pressed into fake pills. Read our polysubstance use page.

Will naloxone hurt someone who isn’t overdosing?

Florida’s iSaveFL program says naloxone will not harm someone who is not having an overdose. In a person who depends on opioids it can bring on withdrawal, so stay with them and call 911.

What if my loved one just left detox?

Their tolerance may be lower, which raises overdose risk. Keep naloxone nearby and help them get to the next level of care quickly. See our aftercare guide. In an emergency, call 911. For a crisis, call or text 988.
