Fentanyl can be used by most adults.
Some patches can be used in children from the age of 2 years and over. However, young children and older people are more likely to get side effects.
Fentanyl patches are usually only used if you’ve been taking other strong opioid painkillers. Your doctor will work out how much fentanyl to give you depending on what dose of other opioids you have been taking.
Fentanyl is not suitable for some people. Tell your doctor before starting the medicines if you:
- have ever had an allergic reaction to fentanyl or any other medicines
- have breathing difficulties such as asthma or a lung condition
- are addicted to alcohol or a heavy drinker
- have a head injury or condition that causes fits or seizures
- have irregular heartbeats (arrhythmia)
- have adrenal gland problems
- have kidney or liver problems
- have an enlarged prostate
- have low blood pressure
- are trying to get pregnant, are pregnant or breastfeeding
