Summary
What conditions fentanyl is used for
Fentanyl is used to treat severe pain, such as pain from cancer, surgery, or injury. It is also used for managing chronic pain in patients who are tolerant to other opioids, which are drugs that relieve pain by acting on the nervous system.
How fentanyl works in the body
Fentanyl works by binding to opioid receptors in the brain and spinal cord, which reduces the perception of pain. This action provides significant pain relief, making fentanyl effective for severe pain conditions.
Directions for Use
Fentanyl is usually prescribed as a patch, lozenge, or injection. Patches are applied to the skin and changed every 72 hours. Lozenge forms should be sucked, not chewed, and injections are administered by healthcare professionals.
The most commonly observed adverse effects of fentanyl
Common side effects of fentanyl include nausea, vomiting, constipation, and drowsiness. These effects vary from person to person and may lessen over time. If you experience new symptoms, talk with your doctor before stopping any medication.
Warnings and Precautions
Fentanyl can cause serious breathing problems, especially when starting or increasing the dose. It should not be used with alcohol or other sedatives. Misuse can lead to addiction, overdose, or death. Always follow your doctor's instructions and keep fentanyl out of reach of others.
