Following is information on contraindications to the use of fentanyl in general, pregnancy & amp; Breastfeeding and children. Please note that the contraindications may vary depending on the dosage form of a drug (eg tablet, syringe, ointment).
When should Fentanyl not be used?
Fentanyl must not be used in case of known hypersensitivity to the active substance, severe impairment of brain function or dependence on opioid painkillers. Fentanyl may only be used if it is carefully weighed by a physician and under his control.
- permanent narrowing of the airways (COPD), other lung diseases or respiratory disorders, as these may be exacerbated by the active substance
- Diseases or injuries that cause increased intracranial pressure or dysphagia
- Cardiac arrhythmia with slow heartbeat in patients with low blood pressure and / or lack of blood
- impaired liver or kidney function, the dose should be reduced by the doctor if necessary
- elderly or emaciated patients because the dose may need to be reduced by the doctor
- Myasthenia gravis, because the drug can cause non-epileptic seizures.
What should you watch out for during pregnancy and lactation?
The active substance should not be taken during the entire pregnancy, since it can make it dependent in the womb and trigger withdrawal symptoms in the newborn after birth.
Before or during birth (including cesarean section) given, the drug may cause an inhibition of respiratory function (respiratory depression) in the child and must therefore not be used.
Although there has been no known harm to the baby so far, the active substance should not be taken while breast-feeding as it passes into the milk. Breast-feeding is usually not necessary with single use.
What should be considered in children?
