Treating pain in patients maintained on methadone or buprenorphine
Behavioral fitness hospitalist David Frenz, MD, medical director for addiction medicine for the HealthEast Care System in St. Paul, Minn., fields masses of questions from acute-care colleagues on the way to manipulate acute or chronic ache in patients with substance use problems. One common query is a way to treat ache in sufferers receiving upkeep therapy with methadone or buprenorphine. It seems that physicians have a totally limited comfort sector with these pills—and lots of misconceptions.
That confusion is comprehensible, Dr. Frenz factors out, given the dense guidelines governing those pills’ scientific use. Part of the confusion is because of the fact that distinct regulations govern wherein and the way methadone and buprenorphine can be used and through whom. Another problem: Because sublingual buprenorphine (Suboxone or Subutex) is a more recent agent, doctors have limited medical experience with it.
While both methadone and buprenorphine are effective analgesics and effective sellers for treating opioid dependency, a few specialists endorse the use of either drug for each purpose concurrently. That provides to the confusion: What have doctors do for sufferers on a renovation opioid agent to offer pain remedies?
When It involves administering methadone, physicians are worried about entering into regulatory warm water. “A lot of hospitalists are afraid to apply methadone because they suppose they’re ‘no longer licensed’ to accomplish that, however that’s now not the case,” Dr. Frenz says. “Any licensed prescriber might also use methadone to treat acute opioid withdrawal syndrome furnished they comply with a few enormously easy federal guidelines.”

These recommendations make up the so-called “seventy-two-hour rule,” which states that methadone may be administered to an affected person (but now not distributed or prescribed for unsupervised use) for up to 3 days. “The motive,” Dr. Frenz explains, “is to alleviate struggling even as suitable transfer of care is being made.”
Hospitalist Michael Miller, MD, scientific director of the NewStart Alcohol/Drug Treatment Program at Meriter Hospital in Madison, Wis., factors out that the rule of thumb applies simplest whilst opioid Addicted Recovery is the number one clinical focus, together whilst a patient is retreating from prescription ache capsules or heroin.
The rule does not come into play whilst methadone-maintained sufferers are admitted to the hospital for other reasons. Under those instances, hospitalists may additionally retain a patient’s methadone indefinitely without walking afoul of the regulation. “You can treat those patients while they’re there, however you couldn’t provide them any methadone on their manner out the door,” Dr. Miller says. “All outpatient prescribing of methadone for addiction needs to be done by a federally licensed methadone clinic.”
As long as sufferers are being admitted for a clinical or psychiatric motive apart from drug addiction, “you’re A-OK persevering with their methadone due to the fact you are making no try to control their opioid use ailment,” Dr. Frenz points out. “It’s just like continuing eye drops for glaucoma.”
Methadone preservation dosing
Methadone dosing, but, is much less straightforward. Both Drs. Frenz and Miller’s advocate confirms patients’ dosing histories with their medical institution. Don’t accept as true patients’ self-reports about the quantity in their preservation dose.

“Some sufferers who’re methadone-maintained on a dose of 100 mg consistent with the day might tell you it’s one hundred fifty mg simply to see if they could get you to put in writing for greater,” says Dr. Frenz. “Hospitalists would be very clever to call patients’ methadone hospital and verify their dosing history.” Another big purpose to name the methadone clinic is to find out while patients had their ultimate protection dose. Otherwise, Dr. Miller says, it’s safe to give newly admitted patients the simplest 30 mg of methadone as an Initial dose on a primary day.
If the affected person has missed three days of maintenance doses, he adds, his hospital could treat the patient at 50% of that dose “after which build them back up.” If the affected person has been far from the health center for a week, the starting dose within the health facility is probably 25% of the regular dose.
“You don’t restart them at the dose they were on because their tolerance has gone down,” Dr. Miller says. Patients who’ve been overlooked only at some point can be given their everyday dose.
Managing acute ache syndromes in methadone-maintained sufferers is a lot like diabetes control
“Methadone or buprenorphine is the equal of basal insulin,” explains Dr. Frenz. “Patients want the medicine to sense stable and function typically. They may also want an extra opioid “bolus insulin by analogy “to deal with the intense pain associated with harm or surgical procedure.”
Hospitalists need to administer the everyday methadone dose for maintenance simplest, including another opioid “preferably utilized in aggregate with NSAIDs and acetaminophen, to lessen general opioid desires “in high-sufficient doses to control ache.
Dr. Frenz notes that opioid-tolerant sufferers will require more-than-normal doses of a supplemental opioid as compared to individuals who are opioid-naive. “As the doses can be enormous, hospitalists and surgeons ought to recollect consulting with someone acquainted with opioid management,” he says. “In our fitness care gadget, those consultations are fielded through the palliative medicinal drug and dependency medication services.”
As lengthy as doses are titrated carefully and sufferers are monitored, physicians don’t want to worry about placing patients at better risk for respiration or relevant anxious machine depression. Studies have shown that patients with dependency or dependence can tolerate the medicine’s depressant effects quickly when higher doses are used for ache manipulation.
And professionals say that hospitalists shouldn’t be overly worried approximately worsening or rekindling a patient’s addiction. “There’s something humorous approximately acute pain that attenuates the rewarding residences of opioids,” Dr. Frenz explains. “Patients acquire analgesia but not euphoria.”
Nor are sufferers of opioid agonist therapy at a great threat of relapse because they’ve obtained opioid analgesics for acute ache. Instead, some studies show that under-treating aches in patients with addiction can also pose a more relapse risk due to the pressure related to that untreated pain.
Things get stickier in terms of buprenorphine. According to Dr. Miller, any health practitioner registered with the Drug Enforcement Agency (DEA) can also administer Buprenex, a parenteral form of buprenorphine, for analgesia. (See “Buprenorphine: doses and indications” under.)
