Before taking this medicine
You should not use Ionsys if you are allergic to fentanyl or to Cepacol (cetylpyridinium chloride), or if you have:
a severe breathing problem such as asthma attacks; or
a blockage in your digestive tract (stomach or intestines).
Some medicines can cause unwanted or dangerous effects when used with Ionsys. You may not be able to use this medicine if you also use certain antibiotics, antifungal medications, heart or blood pressure medications, or medicines to treat hepatitis C or HIV/AIDS. Tell your doctor about all medicines you use.
Some medicines can interact with fentanyl and cause a serious condition called serotonin syndrome. Be sure your doctor knows if you also take medicine for depression, mental illness, Parkinson's disease, migraine headaches, serious infections, or prevention of nausea and vomiting. Ask your doctor before making any changes in how or when you take your medications.
To make sure Ionsys is safe for you, tell your doctor if you have:
any type of breathing problem or lung disease;
a history of head injury, brain tumor, mental illness, alcoholism or drug addiction;
seizures or epilepsy;
liver or kidney disease; or
problems with your gallbladder, pancreas, or thyroid.
It is not known whether Ionsys will harm an unborn baby. If you use Ionsys while you are pregnant, your baby could become dependent on the drug. This can cause life-threatening withdrawal symptoms in the baby after it is born. Babies born dependent on habit-forming medicine may need medical treatment for several weeks. Tell your doctor if you are pregnant or plan to become pregnant.
Fentanyl can pass into breast milk and may harm a nursing baby. Tell your doctor if you are breast-feeding a baby.
How is Ionsys used?
Ionsys is used only while you are in a hospital. A healthcare provider will place the device on your chest or upper arm where you can reach it. A healthcare provider should also remove or replace the device when needed. Do not leave the hospital with a device on your skin.
Fentanyl can slow or stop your breathing. Use this device only as directed.
Fentanyl may be habit-forming, even at regular doses. Never share an Ionsys transdermal device with another person, especially someone with a history of drug abuse or addiction. MISUSE OF NARCOTIC MEDICINE CAN CAUSE ADDICTION, OVERDOSE, OR DEATH, especially in a person using the medicine without a prescription. Selling or giving away Ionsys is against the law.
To release fentanyl from the device, press the dosing button twice. A beep will sound when the dose starts, and a green light will blink for 10 minutes while the dose is delivered. The device can only be activated once every 10 minutes. Tell your doctor if Ionsys seems to stop working as well in relieving your pain.
While you are wearing this device, only you should press the dosing button to control your pain. Do not allow others to press the dosing button for you, or you could receive a fatal overdose.
Never allow a family member or visitor to touch or handle the Ionsys transdermal device. It should be handled only by a healthcare professional. Do not remove or reposition the device yourself. The sticky side of the device contains a high concentration of fentanyl, which could cause a fatal overdose if the medicine gets on your skin. Tell your care provider if the device comes loose or falls off.
The device is worn for 24 hours or until it has delivered 80 doses of fentanyl.
The Ionsys transdermal device may burn your skin if you wear the device during an MRI (magnetic resonance imaging). Certain other medical tests can cause damage to the Ionsys transdermal device. Remove the device before undergoing an MRI, CT scan, x-ray, or similar test.
