Fentanyl Addiction
You're not alone
Fentanyl is a very strong synthetic opioid used medically to treat severe pain. It can also cause dependence and addiction, particularly when used outside medical supervision.
If fentanyl use is becoming difficult to control, this page explains how addiction develops, the warning signs, the risks of overdose and the treatment support available.
You are not alone, and help is available when you are ready.
What is Fentanyl Addiction?
Fentanyl is a synthetic opioid prescribed for severe pain, including pain following surgery or trauma and some forms of cancer pain. It is available in forms including patches, lozenges or tablets, nasal sprays and injections.
Because fentanyl acts powerfully on the central nervous system, dependence can develop even when it is prescribed. Addiction is more likely when it is misused or taken without medical supervision.
The existing page also warns that illegally produced fentanyl can be especially dangerous because strength and dosage may be unpredictable, increasing the risk of overdose.
Recognising the Signs
Fentanyl addiction can involve both physical dependence and changes in behaviour. These signs may indicate that use is becoming harder to control.
Behavioural Signs
- Thinking frequently about getting or taking fentanyl
- Feeling anxious when your supply is running low
- Using fentanyl more often or in larger amounts
- Continuing to use despite problems at work or in relationships
- Prioritising fentanyl over other activities
- Finding it difficult to stop without help
Physical Signs
- Muscle aches
- Nausea and vomiting
- Diarrhoea
- Dilated pupils
- Insomnia
- Agitation
What Causes Fentanyl Addiction?
Fentanyl can cause rapid changes in the brain’s reward and pain systems. Repeated use can lead to tolerance, dependence and compulsive use, even when the drug was first taken for a legitimate medical reason.
Potency
Fentanyl is an extremely powerful opioid. Its effects on the brain can make dependence develop quickly.
Tolerance
Over time, the body can become tolerant, meaning larger or more frequent doses may be needed to achieve the same effect.
Dependence
Once dependent, stopping can trigger withdrawal symptoms and strong cravings, making it difficult to stop without support.
The Impact on Your Health
Fentanyl can affect both physical and psychological health. The greatest immediate danger is overdose, particularly when the dose is uncertain or fentanyl is mixed with other substances.
Physical Health Risks
- Shallow or difficult breathing
- Seizures
- Severe drowsiness or loss of consciousness
- Nausea, vomiting and constipation
- Skin reactions or swelling
- Risk of fatal overdose
Psychological & Behavioural Risks
- Strong cravings
- Anxiety when fentanyl is unavailable
- Loss of interest in other activities
- Compulsive drug-seeking behaviour
- Impaired judgement
- Addiction affecting work, relationships and quality of life
- Overdose symptoms require emergency help
If someone has severe breathing difficulty, seizures, loss of consciousness or other signs of overdose, call 999 immediately. The existing page also highlights naloxone as an emergency treatment used for opioid overdose.
Your Path to Recovery
Fentanyl dependence should be treated with professional medical support. Recovery usually involves managing withdrawal safely, addressing the causes of addiction and continuing support after the initial treatment stage.
Medical Detox
Stopping fentanyl should be medically supervised. Detox support can help manage withdrawal symptoms and reduce medical risks while the drug leaves your system.
Residential Treatment
Residential rehab can provide a structured environment away from access to fentanyl, with medical care and therapy to address both dependence and addictive behaviour.
Ongoing Support
Cravings and other symptoms can continue after detox, so ongoing therapy, relapse-prevention work and recovery support can be important parts of longer-term treatment.
Important: Do not stop fentanyl suddenly without medical advice. If you suspect an overdose, call 999 immediately.
