Cymbalta - Cause For Concern?
Check with your doctor right away if you or your child have bluish lips or skin; chest pain; difficulty with breathing; a fast, pounding or irregular heartbeat or pulse; shortness of breath; or muscle stiffness after receiving fentanyl.
MISUSE OF NARCOTIC MEDICATION CAN CAUSE ADDICTION, OVERDOSE, OR DEATH, especially in a child or other person using the medicine without a prescription.
Before taking this medicine
You should not receive this medicine if you are allergic to fentanyl or other narcotic pain medicines.
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 fentanyl is safe for you, tell your doctor if you have:
any type of breathing problem or lung disease;
history of head injury or brain tumor;
liver or kidney disease;
slow heartbeats;
if you use a sedative like Valium (diazepam, alprazolam, lorazepam, Ativan, Klonopin, Restoril, Tranxene, Versed, Xanax, and others); or
if you have used an MAO inhibitor (isocarboxazid, linezolid, methylene blue injection, phenelzine, rasagiline, selegiline, tranylcypromine) in the past 14 days.
It is not known whether fentanyl will harm an unborn baby. Tell your doctor if you are pregnant or plan to become pregnant.
It is not known whether fentanyl passes into breast milk or if it could harm a nursing baby. Tell your doctor if you are breast-feeding a baby.
How is fentanyl injection given?
Fentanyl is injected into a muscle, or into a vein through an IV. A healthcare provider will give you this injection as part of the anesthesia given for your surgery or medical procedure.
Your breathing, blood pressure, oxygen levels, and other vital signs will be watched closely while you are receiving fentanyl.
You may be given other pain medications to use after your fentanyl treatment is discontinued.

What happens if I miss a dose?
Since fentanyl is given as needed by a healthcare professional for only a short time, you are not likely to be on a dosing schedule.
What happens if I overdose?
Since this medication is given by a healthcare professional in a medical setting, an overdose is unlikely to occur.
What should I avoid after receiving fentanyl?
Fentanyl can cause side effects that may impair your thinking or reactions. You should not plan on driving or doing anything that requires you to be awake and alert right after you are treated with this medication. Dizziness or severe drowsiness can cause falls or other accidents.
Avoid drinking alcohol for several hours after you receive fentanyl.
Fentanyl side effects
Get emergency medical help if you have any signs of an allergic reaction to fentanyl: hives; difficult breathing; swelling of your face, lips, tongue, or throat.
Like other narcotic medicines, fentanyl can slow your breathing. Death may occur if breathing becomes too weak.
Your caregivers will watch for any side effects you have, which may clear up within minutes after stopping the fentanyl infusion or decreasing the dose:
weak or shallow breathing;
fast or slow heart rate;
stiff muscles; or
severe weakness, feeling light-headed or fainting.
Common fentanyl side effects may include:
slowed breathing;
slow heart rate;
muscle stiffness;
dizziness, vision problems;
nausea, vomiting;
itching, sweating; or
high blood pressure (confusion, anxiety, pounding in your neck or ears).
This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.
