Fentanyl

Fentanyl manages breakthrough cancer pain. Can cause constipation. Talk to your doctor about which laxatives and/or stool softeners are best for you to use while taking this medication.

Fentanyl Overview

Updated: 

Fentanyl is a prescription medication used to treat breakthrough cancer pain. It can also be used as part of surgical anesthesia.

Fentanyl belongs to a group of drugs called opioid agonists or narcotic pain medications. These work by changing the way the brain and nervous system respond to pain.

This medication comes in nasal spray, sublingual spray, sublingual (buccal) tablet, lozenge, and transdermal patch forms. The dose and frequency of administration will vary with the indication and dosage form.

This medication is also available in an injectable form to be given directly into a vein (IV) or the muscle (IM) by a healthcare professional.

Common side effects of fentanyl include difficulty breathing, nausea, upset stomach, and difficulty urinating.

Fentanyl can also cause changes in vision, drowsiness, and dizziness. Do not drive or operate heavy machinery until you know how fentanyl affects you.

Fentanyl and Pregnancy

Tell your doctor if you are pregnant or plan to become pregnant.

The FDA categorizes medications based on safety for use during pregnancy. Five categories - A, B, C, D, and X, are used to classify the possible risks to an unborn baby when a medication is taken during pregnancy.

Fentanyl falls into category C. In animal studies, pregnant animals were given this medication and had some babies born with problems. No well-controlled studies have been done in humans. Therefore, this medication may be used if the potential benefits to the mother outweigh the potential risks to the unborn child.

Fentanyl and Lactation

Tell your doctor if you are breastfeeding or plan to breastfeed.

Fentanyl has been detected in human breast milk. Because of the possibility for adverse reactions in nursing infants from fentanyl, a choice should be made whether to stop nursing or to stop use of this medication. The importance of the drug to the mother should be considered.

Fentanyl Usage

Take fentanyl exactly as prescribed.

This medication comes in nasal spray, sublingual spray, sublingual tablet, lozenge, and transdermal patch forms. The dose and frequency of administration will vary with the indication and dosage form.

 

Instructions for use of nasal spray:

To use fentanyl nasal spray, begin by blowing your nose, if you have a runny nose. Remove the protective cap from the bottle tip and hold the bottle so that the nozzle is between your first and second fingers and your thumb is on the bottom. Sit upright and insert the tip of the bottle approximately 1/2 inch into one nostril, pointing the tip toward the bridge of your nose. Close your other nostril with your finger. Press down firmly on the finger grips until you hear a ''click'' sound. You may not feel the spray go into your nose, but as long as the number in the counting window increases by one, the spray has been given. Breathe in gently through your nose and out through your mouth one time after spraying. Do not sniff after spraying the medication into your nose. If your doctor wants you to use two sprays, repeat the adminsitration, using your other nostril. Stay sitting down for at least 1 minute after using fentanyl nasal spray. Do not blow your nose for at least 30 minutes after using fentanyl nasal spray.

 

Instructions for use of sublingual spray:

To use the sublingual spray, first remove the fentanyl sublingual spray unit from the blister package by cutting along the dashed line with a pair of scissors. Swallow any saliva in your mouth. Hold the fentanyl sublingual spray unit upright using your index and middle fingers and thumb. Point the nozzle into your mouth and under your tongue. Squeeze your fingers and thumb together to spray the medication under your tongue. Hold the medication under your tongue for 30 to 60 seconds. Do not spit out the medication or rinse your mouth. The fentanyl sublingual spray is a one-time use unit and will remain locked after use.

 

Instructions for use of sublingual tablets:

Place ABSTRAL (fentanyl) sublingual tablets on the floor of the mouth directly under the tongue immediately after removal from the blister pack. Do not chew, suck, or swallow ABSTRAL tablets. Allow ABSTRAL tablets to completely dissolve in the sublingual cavity. Do not eat or drink anything until the tablet is completely dissolved. If you have a dry mouth, use water to moisten the buccal mucosa before taking ABSTRAL.

 

Instructions for use of lozenges:

Place ACTIQ in your mouth between your cheeks and gums and actively suck on the medicine. Move the lozenge around in your mouth, especially along the inside of your cheeks. Twirl the handle often. Finish the ACTIQ unit completely in 15 minutes to get the most relief. If you finish ACTIQ too quickly, you will swallow more of the medicine and get less relief. Do not bite or chew ACTIQ. You will get less relief for your breakthrough cancer pain.

 

Instructions for use of transdermal patches:

A fentanyl transdermal system may be applied to the chest, back, flank, or upper arm in a place where there is no hair. Patches should not be placed on skin that is oily, burned, cut, irritated, or damaged. Avoid areas that are sensitive or that move around a lot. Do not shave the area where the patch will be placed.

A patch may be applied at any time of the day, but you should change the patch around the same time every 3 days. Do not wear more than one patch at a time, unless directed by your doctor. Before applying the patch, clean the skin and pat the area dry. Open the patch’s protective pouch and peel the plastic backing away from the patch. Take care not to touch the sticky side of the patch. Press the patch to the skin with the palm of your hand for at least 30 seconds. Make sure it sticks well, especially at the edges. Wash your hands after applying the patch. After 3 days, remove the patch and apply a new one in a different spot. If the patch falls off before 3 days, do not replace it with a new patch; wait until 3 days after you put it on to apply a new patch.

 

Injection:

This medication is also available in an injectable form to be given directly into a vein (IV) or the muscle (IM) by a healthcare professional.

The recommended dose/dose range of fentanyl extended release transdermal systems for the treatment of pain is 12 to 100 mcg/hour. Fentanyl transdermal systems are only indicated for patients who are opioid tolerant, meaning they have been taking opioid pain medications for at least one week. The dose will be titrated based on your response to the medication.

 

Injection:

The dose/dose range of fentanyl injection is individualized on the basis of its indication for use. Fentanyl injection can be administered as premedication prior to surgery, for anesthesia induction, as an adjunct to regional anesthesia, or for pain control in the post-operative setting.

 

Fentanyl Overdose

If you take too much fentanyl, call your healthcare provider or local Poison Control Center, or seek emergency medical attention right away.

If fentanyl is administered by a healthcare provider in a medical setting, it is unlikely that an overdose will occur. However, if overdose is suspected, seek emergency medical attention.

WARNING: ADDICTION, ABUSE, and MISUSE; LIFE-THREATENING RESPIRATORY DEPRESSION; ACCIDENTAL EXPOSURE; NEONATAL OPIOID WITHDRAWAL SYNDROME; CYTOCHROME P450 3A4 INTERACTION, and EXPOSURE TO HEAT

Fentanyl transdermal system exposes users to risks of addiction, abuse, and misuse, which can lead to overdose and death. Assess each patient's risk before prescribing, and monitor regularly for development of these behaviors or conditions.

Serious, life-threatening, or fatal respiratory depression may occur. Monitor closely, especially upon initiation or following a dose increase.

Accidental exposure to fentanyl transdermal system, especially in children, can result in fatal overdose of fentanyl.

Prolonged use of fentanyl transdermal system during pregnancy can result in neonatal opioid withdrawal syndrome, which may be life-threatening if not recognized and treated. If opioid use is required for a prolonged period in a pregnant woman, advise the patient of the risk of neonatal opioid withdrawal syndrome and ensure that appropriate treatment will be available.

Initiation of CYP 3A4 inhibitors (or discontinuation of CYP 3A4 inducers) can result in a fatal overdose of fentanyl from fentanyl transdermal system.

Avoid exposing the fentanyl transdermal system application site and surrounding area to direct external heat sources. Temperature dependent increases in fentanyl release from the system may result in overdose and death.
