Because of this, don’t drive or do activities that require you to be fully alert and awake after your treatment. Avoid drinking alcohol for several hours after you take fentanyl. Fentanyl patches pose a danger to kids who can stick them on their skin or mouths. This can cause death by slowing their breathing and lowering oxygen levels in their blood.

Administration
Experts said fentanyl doesn’t just float up into the air and unintentionally expose people nearby. For continuous delivery, a transdermal patch can slowly deliver fentanyl through the skin and into the bloodstream for up to 72 hours. Fentanyl affects people differently, depending on an individual’s size and overall health condition.

Fentanyl Addiction
While it’s safe for your doctor to give you fentanyl in a medical setting, some people abuse it, which can lead to an overdose. The use of fentanyl citrate injection with CYP3A4 inducers or stopping the CYP3A4 inhibitor will require close and repetitive monitoring of the patient. Public Health Ontario’s review highlights the positive impact of drug checking test strips, indicating potential for overdose reduction and safer drug use.

The Rise And Concern Of Counterfeit Pills
Fentanyl is increasingly found in street drugs that have been stamped with illegally purchased pill presses to look like other common pharmaceutical-grade drugs, such as oxycodone. Illicitly manufactured fentanyl is illegal and can be sold as powder, nasal spray or pills that look like other prescription opioids. Fentanyl can be known by street names such as Apache, China Girl, Dance Fever or Goodfellas.
Fentanyl might not be everywhere evenly in your product, so if you only test a portion of your supply you might end up missing it. Fentanyl test strips aren’t legal everywhere because some states consider them to be drug paraphernalia (items you need to do drugs). But a growing number of health and public policy experts are supporting their use along with other harm-reduction strategies. In many states, test strips could be classified as drug paraphernalia, which advocates in Indiana say has prevented some people from carrying them under fear of prosecution. Test strips, on the other hand, are used before drug use to check a supply for the presence of fentanyl. For many people, the best solution for opioid use disorder is medications for opioid use disorder (MOUD).

Offering affordable substance checking solutions, we feature tests for fentanyl, xylazine, and more. Our commitment to safety is bolstered by extensive research, ensuring top-quality products for informed decisions and community health. Of course, the safest option is not to use illegal drugs at all or to seek out a drug addiction treatment program if you need help stopping. But if you’re going to use street drugs, testing them for fentanyl first might save your life. Naloxone, known by its brand name Narcan, is a fast-acting medication that reverses opioid overdoses.
Where To Buy Fentanyl Test Strips For Personal And Institutional Use
A 10-pack of fentanyl test strips retails for $9.99 at CVS. If you suspect someone is overdosing on fentanyl, call 911 immediately. Many people worry that calling emergency services for someone taking an illegal drug will get them in trouble, but this is not true. Many states have laws that protect not only the person who calls for help, but also the person overdosing from legal trouble. Once you’ve been taking fentanyl for a while, your body gets used to it and stopping can be very hard.
Results Within Minutes
- Naloxone and naltrexone are opioid antagonists that reverse the effects of fentanyl.
- Common routes of naloxone administration include IV, IM, IN, or subcutaneous (SC).
- Its strong potency means it can be used in operating rooms, to control pain after surgery and to alleviate pain for people with advanced cancer.
- And if you test only a portion of the drugs, you can miss fentanyl in other parts of the supply.
- They speculate that it may also be a way to tempt teens and young adults to take them.
Fentanyl is a human-made opioid used to treat severe pain. The drug interacts with receptors in your brain to create feelings of pain relief, relaxation, contentment, and pleasure. Drugs may contain deadly levels of fentanyl, and you wouldn’t be able to see it, taste it, or smell it. It is nearly impossible to tell if drugs have been mixed with fentanyl unless you test your drugs with fentanyl test strips. If the bill is passed, it would mean that drug users could test their drugs for fentanyl before consuming them, potentially saving countless lives. Employers could also use fentanyl testing strips to test their employees for drug use, particularly in industries where safety is a concern.
CDC Supports State And Community-level FTS Efforts
You can’t overdose by touching an item containing fentanyl. Some medical fentanyl is delivered through skin patches, but it is absorbed slowly over the course of hours. These patches can’t quickly deliver a high dose of fentanyl. From April 2024 to March 2025, the CDC reported 43,000 synthetic opioid deaths, most of which are from fentanyl, down from nearly 70,000 in the previous similar period.
In An Emergency? Need Treatment?
Fentanyl stays in your system and can be detected by a drug test for 24 to 72 hours. Fentanyl typically relaxes you and puts you in a euphoric state. You may also feel dizzy, drowsy, have vision changes, or have unpleasant side effects such as dry mouth, stomach pain, or anxiety. Some opioids come directly from the opium poppy plant, but manufacturers make fentanyl in a lab and reproduce the chemical structure. After a fentanyl treatment, you may have side effects that hinder your thinking and reactions or cause dizziness or drowsiness.
Fentanyl misuse can lead to unconsciousness, compromise respiratory function and lead to overdose resulting in death. You may be able to get free fentanyl test strips at your local health department. You can also buy them online or get them at places that offer harm reduction services.


The Stop Overdose website educates drug users on fentanyl, naloxone, polysubstance use, and dealing with stigma. However, these strips are not foolproof and should be used with other harm reduction strategies, such as seeking professional addiction treatment.

If A Person Has Naloxone, Is Fentanyl Safe To Use?
It’s commonly sold as heroin and may be an accidental contaminant in drugs like cocaine. This is because a person has no way of knowing how much fentanyl or what type of fentanyl is in their drug. The risks of fentanyl are even greater for people using cocaine, methamphetamine, or other drugs because their bodies are not used to using opioids and even a small amount of fentanyl can be deadly.
