Treatment Name: Fentanyl (Duragesic®)
Fentanyl (Duragesic®) is a Supportive Care Therapy for Pain
How does fentanyl (Duragesic®) work?
Fentanyl is designed to bind to and activate receptors in the brain called mu (pronounced mew) receptors. When bound to mu receptors, fentanyl helps to reduce the pain signals that go to the brain, which provides pain relief.
Goals of fentanyl (Duragesic®) therapy:
Fentanyl is typically taken to relieve moderate to severe chronic pain. The goal of fentanyl therapy is not to completely relieve pain, but to lessen it to a manageable level. It is most commonly prescribed as a long-acting patch (Duragesic®) that delivers the medication through the skin (transdermal).
How is fentanyl (Duragesic®) therapy given?
Doses of fentanyl can vary greatly depending upon the amount of pain that you are experiencing and the amount of fentanyl or other opioid medications that you are currently taking.
Typical starting doses for fentanyl (Duragesic®):
- 12 mcg/hr or 25 mcg/hr transdermal patch that is changed every 3 days (72 hours)
- In some cases, your doctor may prescribe the patch to be changed every 2 days (48 hours)
- Once a fentanyl patch is applied, it may take 8 to 12 hours to take full effect. Likewise, once a patch is remvoed, it may take 8 to 12 hours for the medicine to wear off
Fentanyl can be used while in the hospital or it can be used at home. Because fentanyl is used for chronic pain, your doctor determines the duration of therapy.
Store fentanyl at room temperature (77°F).
What are the most common side effects from fentanyl?
In the prescribing label information (Duragesic® package insert), the most commonly reported side effects from fentanyl are shown here:
- Nausea and vomiting
- Decreased libido
- Slow heartbeat
- Small pupils
Note: The exact percentages of patients that will experience fentanyl side effects is unknown because it has been used under widely varying patient populations in a variety of clinical trials.
The use of fentanyl during pregnancy can cause opioid withdrawal syndrome in newborn babies. Fentanyl should only be used in pregnant women and women who are breastfeeding if your doctor determines that the potential benefits to the mother outweigh the potential risks to the baby.

How often is monitoring with fentanyl (Duragesic®) needed?
Labs (blood tests) are not routinely done with fentanyl therapy, but may be checked periodically. Labs may include: Comprehensive Metabolic Panel (CMP) plus any others your doctor may order.
Fentanyl may slow how many times you take a breath per minute. This is known as your respiratory rate. Some patients choose to purchase a pulse oximeter, or "pulse ox," monitor to ensure that they they are maintining their oxygen levels, or oxygen saturation, at an adequate level as recommended by their Doctor.
How often is imaging needed with fentanyl (Duragesic®) therapy?
Imaging is not routinely needed during fentanyl therapy.
How might blood test results/imaging affect fentanyl (Duragesic®) treatment?
Depending upon the results, your doctor may advise to continue fentanyl as planned, change your dose, or switch to an alternative pain medication.
Questions to Ask Your...
A better understanding of your treatments will allow you to ask more questions of your healthcare team. We then hope that with the answers, you will get better results and have greater satisfaction with your care. Because we know it's not always easy to know what questions to ask, we've tried to make it easy for you!
Choose any healthcare provider below to see common questions that you may want to ask of this person. Then, either print each list to bring to your clinic visits, or copy the questions and send them as a message to your healthcare team through your electronic medical record.
What are some of the most important things to know about fentanyl (Duragesic®) while receiving therapy?
- Always place your fentanyl patch on an intact, non-irritated part of your skin. Common sites for placement include the chest, upper arms, back, or stomach. Clean the area prior to each use. If body hair is present, you may clip the hair but don’t shave. Wash your hands immediately after applying. Apply to a different body site the next time you change your patch
- After removing an old patch, fold the sticky side of patch together and dispose of it right away. Used patches may still contain medication that could be dangerous to babies, children, or adults for whom fentanyl has not been prescribed
- Avoid exposing yourself to sources of heat (sunbathing, heating pad, electric blanket, tanning bed, hot tub, sauna) while wearing the fentanyl patch as this may alter the absorption of fentanyl through your skin
- In the event of an overdose, naloxone (Narcan®) may be used to reverse the effects of fentanyl. Patients who require naloxone may have rebound pain due to the reversal of the pain relieving effect of fentanyl
- Fentanyl slows down the movement of the intestines and may cause constipation as a common side effect. If you are not having at least one bowel movement every other day, over-the-counter laxatives such as Senna-S® or MiraLAX® may help to keep your bowels regular
- Fentanyl is a FDA Schedule II medication and cannot be prescribed with refills. Before you run out of your medication, be sure to contact your doctor to get another prescription ahead of time. Abruptly stopping fentanyl may cause withdrawal symptoms and increased pain
- Taking other depressant medications such as benzodiazepines (lorazepam, alprazolam, midazolam, etc.) or drinking alcohol can increase side effects and can slow your breathing and can be life threatening. Try to limit taking these types of medications together when possible
- Be sure to store fentanyl in a very safe place away from children and pets and consider storing it in a locked container or cabinet
- A pharmacist should ALWAYS review your medication list to ensure that drug interactions are prevented or managed appropriately. Certain antifungal and seizure medications may interact with fentanyl causing either increased blood levels causing increased side effects or cause decreased levels and decreased effectiveness of fentanyl

What is Pain?
Many treatment options for pain exist. Watch our video to learn more about pain and available treatments.
What is an opioid medication?Opioids are a class of medications that are similar in structure to opium and are commonly used to treat pain. These medications are very effective at treating pain symptoms, but should be used at the lowest dose necessary as directed by your doctor to relieve pain as these medications can lead to misuse, abuse, and addiction.
What is a CMP?
A Comprehensive Metabolic Panel (CMP) is a frequently ordered blood test that tells clinicians the status of your: 1) Electrolytes & Acid/Base status, 2) Kidney function, 3) Liver function, 4) Blood sugar, and 5) Calcium at the time the test was taken. It is commonly used to monitor liver and kidney function when beginning new medications such as chemotherapy. A total of 14 tests are run simultaneously and are shown below.
Electrolytes & Acid/Base status:
1) Sodium, 2) Potassium, 3) Carbon dioxide, 4) Chloride
5) BUN (blood urea nitrogen), 6) Serum creatinine (Scr)
7) AST, 8) ALT, 9) Total bilirubin, 10) Alk Phos, 11) Albumin, 12) Total protein
