How does this medication work? What will it do for me?
Fentanyl belongs to a group of medications called opioids. Fentanyl is used to treat persistent chronic (long-term) severe pain for those who need constant pain relief and are currently taking other opioid (narcotic) medications. It acts on the brain to increase pain tolerance.
This medication may be available under multiple brand names and/or in several different forms. Any specific brand name of this medication may not be available in all of the forms or approved for all of the conditions discussed here. As well, some forms of this medication may not be used for all of the conditions discussed here.
Your doctor may have suggested this medication for conditions other than those listed in these drug information articles. If you have not discussed this with your doctor or are not sure why you are using this medication, speak to your doctor. Do not stop using this medication without consulting your doctor.
Do not give this medication to anyone else, even if they have the same symptoms as you do. It can be harmful for people to use this medication if their doctor has not prescribed it
What form(s) does this medication come in?
Mylan Fentanyl Patch is a skin patch that gradually delivers fentanyl through the skin into the bloodstream for 72 hours. The amount of fentanyl released per hour from each rectangular transparent patch is directly related to the surface area of the patch. The remaining components of the patch are pharmacologically inactive.
12 µg per hour
Each 3.13 cm² patch contains a total of 1.28 mg of fentanyl. It provides fentanyl at a rate of 12 µg per hour delivered through the skin into the bloodstream. Nonmedicinal ingredients: silicone adhesive, dimethicone, polyolefin film backing, white ink, polyester release liner.
25 µg per hour
Each 6.25 cm² patch contains a total of 2.55 mg of fentanyl. It provides fentanyl at a rate of 25 µg per hour delivered through the skin into the bloodstream. Nonmedicinal ingredients: silicone adhesive, dimethicone, polyolefin film backing, white ink, polyester release liner.
50 µg per hour
Each 12.5 cm² patch contains a total of 5.10 mg of fentanyl. It provides fentanyl at a rate of 50 µg per hour delivered through the skin into the bloodstream. Nonmedicinal ingredients: silicone adhesive, dimethicone, polyolefin film backing, white ink, polyester release liner.
75 µg per hour
Each 18.75 cm² patch contains a total of 7.65 mg of fentanyl. It provides fentanyl at a rate of 75 µg per hour delivered through the skin into the bloodstream. Nonmedicinal ingredients: silicone adhesive, dimethicone, polyolefin film backing, white ink, polyester release liner.
100 µg per hour
Each 25 cm² patch contains a total of 10.20 mg of fentanyl. It provides fentanyl at a rate of 100 µg per hour delivered through the skin into the bloodstream. Nonmedicinal ingredients: silicone adhesive, dimethicone, polyolefin film backing, white ink, polyester release liner.
How should I use this medication?
The dose of fentanyl transdermal patch must be individualized and is based on many factors, including the dose of opioid medication that a person is currently using before starting this medication.
Many things can affect the dose of a medication that a person needs, such as body weight, other medical conditions, and other medications. If your doctor has recommended a dose different from the ones listed here, do not change the way that you are using the medication without consulting your doctor.
Apply the patch to non-irritated and non-irradiated (not exposed to radiation) skin on a flat surface such as the chest, back, flank (side of the body between the upper abdomen and back), or upper arm. Hair at the application site should be clipped (not shaved) before applying a patch.
Clean the area with water only; do not use soaps, oils, lotions, alcohol, or any other agent that might irritate the skin. Using soap, alcohol, or other chemicals to clean the skin may cause the fentanyl to be absorbed faster, causing unwanted side effects. After cleaning, allow the skin to dry completely before applying the patch.
Each patch may be worn continuously for 72 hours. A new patch should be applied on a different skin site after removal of the previous one. This helps to prevent skin irritation, which may increase the speed that the fentanyl is absorbed through the skin.
The patch should be pressed firmly in place with the palm of the hand for 30 seconds. Make sure the contact is complete – especially around the edges. The patch should not be folded so that only part of the patch is exposed. If the patch does not stick to the skin properly, tape the edges of the patch with first-aid tape. If the patch still does not stick, you can cover the patch with a transparent adhesive film dressing recommended by your doctor or pharmacist.
If the patch falls off before 72 hours have passed, you may apply a new patch to a new site. Wash your hands immediately with water only, after applying or removing the patch. Consult the package insert, your doctor, or your pharmacist for additional instructions on how to use the medication.
Do not use the patch if it is cut, damaged, or altered in any way.
After 72 hours, there is still enough medication in the patch to cause serious harm to someone who is not using the fentanyl patch for pain control. Accidental exposure to the fentanyl patch may cause death or serious medical problems. When you remove the patch, fold it in half and dispose of it safely, somewhere that pets and other people will not come into contact with it.
Maximum pain relief may not occur for up to 72 hours after first starting this medication. Your doctor may give you a short-acting pain control medication during this period.
This medication may be habit-forming if taken for long periods of time. Do not stop taking this medication without talking with your doctor. If this medication is stopped suddenly, you may experience withdrawal symptoms such as:
- trouble sleeping
If you plan on stopping the medication, your doctor may want you to reduce the dose gradually to reduce the severity of withdrawal effects.
Do not change the dose of the patch you are using or the way you are applying the patch without direction from your doctor. If you experience any of the following side effects of too much fentanyl in the body, seek immediate medical help:
- cold or clammy skin
- feeling faint
- severe sleepiness
- slow heartbeat
- slow or shallow breathing
- trouble breathing
- unable to think, walk, or talk normally
It is important to use this medication exactly as prescribed by your doctor. If a patch is left on for more than 3 days, change the patch as soon as you remember. Do not apply 2 patches to make up for a missed one. If you are not sure what to do after missing a dose, contact your doctor or pharmacist for advice.
Store this medication at room temperature and keep it out of the reach of children.
Do not dispose of medications in wastewater (e.g. down the sink or in the toilet) or in household garbage. Ask your pharmacist how to dispose of medications that are no longer needed or have expired.

Are there any other precautions or warnings for this medication?
Before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.
Abdominal conditions: Fentanyl may make the diagnosis of abdominal conditions more difficult or it may worsen these conditions. If you have abdominal conditions such as inflammatory or obstructive bowel disease, acute cholecystitis, or pancreatitis, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Accidental exposure: Accidental exposure to this medication may lead to serious complications or death. Accidental exposure can occur when a patch is transferred to someone else through hugging or moving them in bed. Children are especially at risk. If this happens, immediately remove the patch from the person, wash the area with water, and seek immediate medical attention. If you are applying the patch for someone, wash your hands with water only immediately after applying or removing the patch.
After use, the patch still contains enough medication to serious harm someone who is not using fentanyl. When you remove the patch, fold it in half, so the sticky side sticks to itself. Return the used patches to your pharmacy for safe disposal. Do not discard the used patch in the household garbage.
Dependence and withdrawal: As with other opioid medications (narcotics), fentanyl may become habit-forming if taken for long periods of time. If you have a history of past or current substance use problems you may be at greater risk of developing abuse or addiction while taking this medication. Drug abuse is not a problem for people who require this medication for pain relief. Physical dependence (a need to take regular doses to prevent physical symptoms) has been associated with some narcotic analgesics.
Withdrawal symptoms may be experienced if the dose is significantly reduced or suddenly discontinued. Reducing the dose gradually under medical supervision can help prevent or decrease these withdrawal symptoms when this medication is no longer required for pain control.
Difficulty breathing: Fentanyl can cause serious and life-threatening breathing problems. If you experience slowed breathing or difficulty breathing, seek immediate medical attention. If you have lung problems and are taking other medications that can slow breathing, you are more at risk of experiencing these symptoms.
Make sure you follow the instructions on how to properly use this medication. If you have any questions, contact your doctor or pharmacist. If you have a chronic lung condition, such as bronchitis, emphysema, or asthma, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Drowsiness/reduced alertness: This medication may impair the mental or physical abilities required for certain tasks, such as driving a car or operating machinery. Do not drive or operate dangerous machinery while using this medication until you have determined how this medication affects you.
Fever or heat exposure: If you develop a fever you may get higher doses than expected from the patch because the release of medication depends on heat. Tell your doctor if you develop a fever, and have a plan in place in the event that your body temperature rises.
Avoid exposing the application site to direct external heat sources, such as heating pads, electric blankets, heated water beds, heat lamps, hot water bottles, saunas, hot whirlpool spa baths, or intensive sunbathing. This exposure to heat can cause the patch to release too much medication.
Head injury: If you have head injuries or increased pressure in the head you may have a higher risk of experiencing side effects (breathing problems) or worsening of your condition while taking this medication. Discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Kidney function: The kidneys are partially responsible for removing fentanyl from the body. If you have reduced kidney function you may experience increased side effects of fentanyl as a result of it not being removed as quickly as expected.
If you have kidney disease or reduced kidney function, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Liver function: Fentanyl is broken down by the liver so it can be removed from the body through the kidneys. Liver disease or reduced liver function may cause a build-up of fentanyl in the body and cause side effects. If you have liver disease or decreased liver function, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
If you experience symptoms of liver problems (e.g., abdominal pain, persistent vomiting, feeling unwell, fever, itching, yellowing of the skin and eyes, dark urine), contact your doctor immediately.
Slowed heart rate: This medication can cause a serious and life-threatening reduced heart rate. If this occurs, seek immediate medical attention. If you have an irregular heartbeat and are taking other medications that can slow heart rate, you are more at risk of experiencing these symptoms.
If you have a slowed heart rate or heart rhythm problems, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Stopping medication: Do not stop using fentanyl abruptly, since withdrawal symptoms may occur if fentanyl is stopped suddenly. These symptoms include seizures, irritability, sleep problems, agitation, tremors, diarrhea, abdominal cramps, vomiting, headache, muscle cramps, extreme anxiety, tension, restlessness, sweating, and confusion. Your doctor will advise you on how to safely stop taking fentanyl if you no longer require it for pain control.
Tolerance: Fentanyl transdermal patches may lead to tolerance when used for a long period of time. Tolerance means that your body gets used to the medication so that more medication may be needed to produce the same pain relief. Your doctor will recommend the dose of fentanyl patch that is most appropriate for you. Do not change your dose or the way you are using the medication on your own. Speak to your doctor if you have any questions.
Pregnancy: Fentanyl crosses the placental barrier and may cause harm to an unborn baby. Withdrawal symptoms have been noted in newborns of mothers who used fentanyl during pregnancy. This medication should not be used during pregnancy unless the benefits outweigh the risks. If you become pregnant while taking this medication, contact your doctor immediately.
Breast-feeding: Fentanyl passes into breast milk. If you are a breast-feeding mother and are using fentanyl, it may affect your baby. Talk to your doctor about whether you should continue breast-feeding.
Children: The safety and effectiveness of using this medication have not been established for children less than 18 years of age.
Seniors: Seniors may be more sensitive to the effects of this medication and may require lower doses.
