Duragesic for Neuropathy

This letter to The Body (see link below)is slightly disturbing because it suggests that the drug is an effective remedy for neuropathy, without giving any details:

That said, the writer is 'sharing' an experience and not promoting this particular drug and furthermore, the article is almost eight years old, so there is every chance that opinions and/or information, have changed since then. My point is that if a doctor has suggested the drug to a patient then that gives it a certain 'credibility' and who can blame the patient for then passing on the suggestion to others?

"Perhaps I'm writing this more to share than anything. I know how long I have searched for something to help with my Peripheral Neuropathy. And FINALLY- my Dr. just put me on Durogesic (Transdermal Fenatyl) Skin Patch use for Chronic Pain. I urge anyone with PN to ask your Dr. about Durogesic."

Here are the details - make your own minds up if you want to try to persuade your doctor to put you on it. it comes from the Duragesic manufacturers' site itself and they don't pull any punches!(see link below)

Welcome. What is DURAGESIC®?

The DURAGESIC® (fentanyl transdermal system) CII patch is a strong prescription pain medication for moderate to severe chronic pain that can provide long-lasting relief from persistent pain.

Through its innovative patch technology, DURAGESIC® delivers fentanyl, an opioid pain medication, into the body slowly through the skin, where it works to relieve pain for up to 3 days (72 hours).

DURAGESIC® is strong medicine for serious pain. The DURAGESIC® patch should only be used when other less potent medicines have not been effective and when pain needs to be controlled around the clock.

Boxed Warning

DURAGESIC® (fentanyl transdermal system) CII contains a high concentration of a potent Schedule II opioid agonist, fentanyl. Schedule II opioid substances which include fentanyl, hydromorphone, methadone, morphine, oxycodone, and oxymorphone have the highest potential for abuse and associated risk of fatal overdose due to respiratory depression. Fentanyl can be abused and is subject to criminal diversion. The high content of fentanyl in the patches (DURAGESIC®) may be a particular target for abuse and diversion.

DURAGESIC® is indicated for management of persistent, moderate to severe chronic pain that:
Requires continuous, around-the-clock opioid administration for an extended period of time, and
Cannot be managed by other means such as nonsteroidal analgesics, opioid combination products, or immediate-release opioids
DURAGESIC® should ONLY be used in patients who are already receiving opioid therapy, who have demonstrated opioid tolerance, and who require a total daily dose at least equivalent to DURAGESIC® 25 mcg/hr. Patients who are considered opioid-tolerant are those who have been taking, for a week or longer, at least 60 mg of morphine daily, or at least 30 mg of oral oxycodone daily, or at least 8 mg of oral hydromorphone daily or an equianalgesic dose of another opioid.

Because serious or life-threatening hypoventilation could occur, DURAGESIC® is contraindicated:
In patients who are not opioid-tolerant
In the management of acute pain or in patients who require opioid analgesia for a short period of time
In the management of post-operative pain, including use after out-patient or day surgeries (e.g., tonsillectomies)
In the management of mild pain
In the management of intermittent pain (e.g., use on an as needed basis [prn])
(See CONTRAINDICATIONS section of the full Prescribing Information for further information.)

Since the peak fentanyl concentrations generally occur between 20 and 72 hours of treatment, prescribers should be aware that serious or life-threatening hypoventilation may occur, even in opioid-tolerant patients, during the initial application period.

The concomitant use of DURAGESIC® with all cytochrome P450 3A4 inhibitors (such as ritonavir, ketoconazole, itraconazole, troleandomycin, clarithromycin, nelfinavir, nefazodone, amiodarone, amprenavir, aprepitant, diltiazem, erythromycin, fluconazole, fosamprenavir, grapefruit juice, and verapamil) may result in an increase in fentanyl plasma concentrations, which could increase or prolong adverse drug effects and may cause potentially fatal respiratory depression. Patients receiving DURAGESIC® and any CYP3A4 inhibitors should be carefully monitored for an extended period of time and dosage adjustments should be made if warranted. (See CLINICAL PHARMACOLOGY-Drug Interactions, WARNINGS, PRECAUTIONS, and DOSAGE AND ADMINISTRATION sections of the full Prescribing Information for further information.)

The safety of DURAGESIC® has not been established in children under 2 years of age. DURAGESIC® should be administered to children only if they are opioid-tolerant and 2 years of age or older. (See PRECAUTIONS - Pediatric Use section of the full Prescribing Information.)

DURAGESIC® is ONLY for use in patients who are already tolerant to opioid therapy of comparable potency. Use in non-opioid tolerant patients may lead to fatal respiratory depression. Overestimating the DURAGESIC® dose when converting patients from another opioid medication can result in fatal overdose with the first dose (see DOSAGE and ADMINISTRATION – Initial DURAGESIC® Dose Selection - section of full Prescribing Information for further information). Due to the mean elimination half-life of approximately 20-27 hours, patients who are thought to have had a serious adverse event, including overdose, will require monitoring and treatment for at least 24 hours.

DURAGESIC® can be abused in a manner similar to other opioid agonists, legal or illicit. This risk should be considered when administering, prescribing, or dispensing DURAGESIC® in situations where the healthcare professional is concerned about increased risk of misuse, abuse, or diversion.

Persons at increased risk for opioid abuse include those with a personal or family history of substance abuse (including drug or alcohol abuse or addiction) or mental illness (e.g., major depression). Patients should be assessed for their clinical risks for opioid abuse or addiction prior to being prescribed opioids. All patients receiving opioids should be routinely monitored for signs of misuse, abuse, and addiction. Patients at increased risk of opioid abuse may still be appropriately treated with modified-release opioid formulations; however, these patients will require intensive monitoring for signs of misuse, abuse, or addiction.

DURAGESIC® patches are intended for transdermal use (on intact skin) only. Do not use a DURAGESIC® patch if the seal is broken or the patch is cut, damaged, or changed in any way.

Avoid exposing the DURAGESIC® application site and surrounding area to direct external heat sources, such as heating pads or electric blankets, heat or tanning lamps, saunas, hot tubs and heated water beds, while wearing the system. Avoid taking hot baths or sunbathing. There is a potential for temperature-dependant increases in fentanyl released from the system resulting in possible overdose and death. Patients wearing DURAGESIC® systems who develop fever or increased core body temperature due to strenuous exertion should be monitored for opioid side effects and the DURAGESIC® dose should be adjusted if necessary.

To my mind, we need to be really careful about what we suggest in forums (however well-intentioned). This blog has also been guilty of exactly that but the advice to all patients always remains the same: read everything you can and gather information but don't do anything hasty without being aware of all the facts and consulting your doctor. Many people are desperate enough to try anything but it's essential they are aware of all the properties of the drugs they take. Duragesic, like all opioids, is not M&Ms!
