What happens if I miss a dose (Ionsys)?
Since a fentanyl transdermal device is applied by a healthcare professional in a hospital setting, it is not likely that you will miss a dose.
What happens if I overdose (Ionsys)?
Seek emergency medical attention or call the Poison Help line at 1-800-222-1222. A fentanyl overdose can be fatal.
Overdose symptoms may include slow breathing, extreme weakness or dizziness, pinpoint pupils, cold and clammy skin, or fainting.
What should I avoid while using a fentanyl transdermal device (Ionsys)?
This medication is for use only on the skin. Avoid touching the gel inside a device with your fingers. Do not allow the medicine to come into contact with your eyes, nose, mouth, or lips. If it does, rinse with water. Do not use soap or other chemicals.
Fentanyl can cause side effects that may impair your thinking or reactions. Be careful if you do anything that requires you to be awake and alert.
Avoid drinking alcohol, which can increase dizziness or drowsiness.
What other drugs will affect fentanyl transdermal (Ionsys)?
Tell your doctor if you regularly use other medicines that make you sleepy (such as cold medicine, other pain medicine, muscle relaxers, and medicine for depression or anxiety). They can add to extreme drowsiness or breathing problems caused by fentanyl.
Tell your doctor about all other medicines you use, especially:
- carbamazepine (Tegretol, Carbatrol);
- phenytoin (Dilantin);
- diltiazem (Cartia, Cardizem);
- St. John's wort;
- rifampin (Rifater, Rifamate, Rimactane);
- an antibiotic such as clarithromycin (Biaxin), dalfopristin/quinupristin (Synercid), erythromycin (E.E.S., EryPed, Ery-Tab, Erythrocin, Pediazole), or telithromycin (Ketek);
- antifungal medication such as itraconazole (Sporanox), ketoconazole (Extina, Ketozole, Nizoral, Xolegal), miconazole (Oravig), or voriconazole (Vfend); or
- HIV/AIDS medicine such as atazanavir (Reyataz), delavirdine (Rescriptor), fosamprenavir (Lexiva), indinavir (Crixivan), nelfinavir (Viracept), saquinavir (Invirase), or ritonavir (Norvir, Kaletra).
This list is not complete and other drugs may interact with fentanyl. Tell your doctor about all medications you use. This includes prescription, over-the-counter, vitamin, and herbal products. Do not start a new medication without telling your doctor.
