What happens if I miss a dose?
Since fentanyl transdermal is used as needed, you may not be on a dosing schedule. If you are using the skin patches regularly, apply the missed patch as soon as you remember. Continue wearing the patch for up to 72 hours and then apply a new one if needed for pain. Do not wear extra patches to make up a missed dose.
What happens if I overdose?
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 extreme drowsiness, weak pulse, fainting, and slow breathing (breathing may stop).
What should I avoid while using a fentanyl transdermal patch?
This medication is for use only on the skin. Avoid touching the sticky side of a skin patch 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.
This medication may impair your thinking or reactions. Avoid driving or operating machinery until you know how fentanyl will affect you.
Avoid drinking alcohol, which can increase dizziness or drowsiness.
Do not expose the skin patch to heat while you are wearing it. This includes a hot tub, heating pad, sauna, or heated water bed. Heat can increase the amount of drug you absorb through your skin and may cause harmful effects.
What other drugs will affect fentanyl transdermal?
Cold or allergy medicine, sedatives, sleeping pills, muscle relaxers, and medicine for seizures, depression or anxiety can add to sleepiness caused by fentanyl. Tell your doctor if you regularly use any of these medicines.
