Does Suboxone Cause SIDS?

In a recent Google search about Suboxone and pregnancy, one of the top links included the frightening statement that Suboxone and buprenorphine have been linked to SIDS or sudden infant death syndrome, commonly called ‘crib death.’ The statement was from a health forum where a woman wrote about taking Suboxone during pregnancy.  She wrote that her […]

Suboxone Side Effects pt. 2

We can now leave naloxone out of the discussion, and focus on the side effects of Suboxone that are caused by buprenorphine. Side effects are symptoms caused by a given medication that are not part of the therapeutic benefit of that medication.  Whether a symptom is a side effect depends on the reason for taking […]

Treating Addiction with Brain Surgery

Today I read about the stereotactic brain surgery used to treat opioid dependence in China over the past ten years.   The procedure is relatively straightforward; the patient’s skull is clamped in place while small holes are drilled, guided by computerized, 3-dimensional maps of the brain.  Probes are inserted deeply through brain tissue to the nucleus accumbens, where […]

Europe Dumps Meprobamate

The European Medications Agency is banning meprobamate and meprobamate-containing medications from the sale in Europe, after concluding that the risks from the medication exceed the therapeutic benefit. The removal comes six months after a decision by the same agency to suspend authorization for all marketing for the medication.  I have not read of any similar […]

Xanax for Anxiety? Think Again!

Anxiety is one of the most common presenting complaints for people who come to my psychiatric practice. By the time people with anxiety visit a psychiatrist, they have usually discussed their symptoms with friends and family members, and some have been to their family care physician. And as a result of these initial ‘consultations’, they […]

The End of Narcotic Pain Medication?

The LA Times ran a very interesting story a few days ago about deaths from overdose of narcotic pain medications.  I strongly encourage readers of this blog to read the story, which discusses the issue from the perspectives of doctors, patients, and family members. The story reports that a small number of Southern-California doctors wrote […]

Codeine Never Works For Me…

The FDA recently released a Drug Safety Announcement about the use of codeine in young children after tonsillectomy/adenoidectomy surgery for obstructive sleep apnea.  I was somewhat surprised to see a safety announcement on a medication that has been in use for decades, but the release underscores our improved knowledge of drug metabolism, and the broadening demographics […]

Suboxone and Tooth Decay

I have received a several emails over the past few years from people who experienced deteriorating dental health while taking buprenorphine or Suboxone.  I also have patients in my practice who have had extensive dental work, and wonder if Suboxone is to blame for their cavities or other problems.

I wrote about this issue several years ago.  At that time I wrote that there was no evidence that sublingual buprenorphine or Suboxone cause or accelerate tooth decay.  After writing the article I received a number of angry emails from people who insisted that I was wrong.

Let’s step back for a moment to highlight the difference between thinking something vs. proving something.  Some people misunderstood my comments about tooth decay and Suboxone, thinking that I was arguing that Suboxone does not harm teeth.  That was not what I wrote.  My point was that as of that time, there was no evidence that Suboxone or buprenorphine caused tooth decay.  When I write about the science of buprenorphine, I try my best to distinguish between what I think is true vs. what was established through scientific study.

I recently met with a patient who has had extensive dental work over the past few years, the same time that she was taking sublingual buprenorphine.  She asked if I thought that the two were related.   I made a few comments (that I’ll be getting to), but also promised her that I would do a literature search, to see whether any connection has since been established.  Ironically, a case report of a woman on Suboxone who required extensive dental work was just published yesterday.  The case report is in the latest issue of The American Journal on Addictions, and the same case is cited in the October 20, 2012 edition of Reactions Weekly.  This latter citation is a newsletter that follows multiple sources for any report of adverse drug reactions, described in more detail here.

The world of science is not efficient.  Knowledge moves forward slowly, based on findings amassed from many studies, often repeated multiple times.  Case reports are not intended to prove something.  In fact, case reports are often unusual clinical examples that defy the norm.  They are often published to point out an area that deserves more study.

I cannot copy the case report here because of copyright laws.  But the case described a 35-y-o woman who used oxycodone for about a year at doses up to 160 mg per day, and then went on buprenorphine/naloxone.  After 18 months, her dentist told her that she had extensive decay of 4 molars requiring root canal.  She reportedly had minimal history of dental problems before starting opioids or buprenorphine.

The author of the case report hypothesized that if there is a connection between Suboxone and tooth decay, one reason could be xerostomia, i.e. dry mouth, caused by buprenorphine.  The lack of saliva was my thought, too, as a mediator of any possible effects of buprenorphine on teeth.  Saliva serves an important role in dental health, including rinsing away food particles and acting as a buffer.  The patient in the case report did not report a dry mouth, so the author pointed out that all opioids have some ability to suppress the immune response, and perhaps buprenorphine and/or naloxone reduce the immune response, allowing for greater destruction of teeth by bacteria.

The case report, surprisingly, did not say which buprenorphine product(s) the patient had used, e.g. tablets, film, or generic buprenorphine.

What needs to happen next is for someone to do a case-control study of patients on buprenorphine, to see if they are more or less likely to have tooth decay.  The most valuable study is usually a prospective, randomized clinical trial;  that would not be proper here, since it would not be appropriate to randomize subjects to buprenorphine vs. no buprenorphine.  But a close second would be a case controlled study, where patients on buprenorphine are matched to ‘controls’ with similar characteristics— age, sex, eating habits, income level, education, etc.– and the dental outcomes are followed forward over a number of years.  A less-costly, less-reliable study is one that looks backward, comparing patients on buprenorphine with those not on buprenorphine to see which group has a higher incidence of dental caries.

We are not much better off at this point in our knowledge of whether Suboxone or buprenorphine predispose toward tooth decay.  The case report only mirrors what I see in my practice.  But as I often tell patients, I have other patients who are not on buprenorphine or Suboxone, who have tooth problems.  I also have patients on Suboxone with great teeth.  Hopefully some ambitious PhD candidate will sort through the issue soon.

Is My Withdrawal Permanent?!

A question from a reader: I am trying to decide what my best course of action might be in dealing with protracted withdrawals from a number of drugs, including benzodiazepines. My history is as follows:  I was snorting Oxycontin for about 6 months and went into treatment to stop.  Before entering the rehab hospital they […]

Treatment? Or Murder?

I subscribe to Google news alerts for the phrase ‘overdose deaths.’  Google Alerts are a great way to follow any topic; subscribers receive headlines from newspapers and web sites for certain keywords from around the world. One thing that has become clear from my subscription is that there is no shortage of stories about deaths from opioids! Every day I see one article after the next, as news reporters notice the loss of more and more of their communities’ young people.

Along with the reports of overdoses are stories about doctors who are increasingly being prosecuted for the deaths of their patients. In an earlier post I described the case of Dr. Schneider and his wife, a nurse, who were tied to a number of overdose deaths in Kansas. That case stood out by the sheer number of deaths; the State charged the couple with the deaths of 56 patients. Cases involving fewer patients have become relatively common. The latest case that I’ve read about is a doctor in Iowa, who is accused of causing or contributing to the deaths of 8 people.

I try to present both sides of the argument when I write about this topic. I have been faced with the difficult decision over whether or not to prescribe narcotics many times, and I understand a doctor’s dilemma. The doctor sees a person who is in pain, and knows that there is a pill that will reduce that pain. But the doctor also knows, or SHOULD know, that initiating a prescription for narcotic pain medication always has unintended consequences, no matter how good the intentions of both doctor and patient.

In the Iowa case, the dilemma over narcotic-prescribing is very clear. The prosecution states that the doctor prescribed pain medication to drug addicts.  On the surface, that sounds bad, right? One gets the mental picture of dirty, lazy people, dissolving tablets in a spoon, over a candle, and then injecting the mixture. But reality is much more complicated. Patients with histories of opioid dependence do not always have track marks. And even if we tattooed the letter A across their chests, there are addicts who are in need of pain treatment. Are we to decide that every person who has become addicted to pain medication gives up the right to pain treatment?  And we know that many of the patients addicted to opioids became addicted through the course of pain treatment from their physician— so I would expect that on average, patients addicted to opioids would have a higher incidence of chronic pain, and vice versa.

I do not find it reasonable to make patients with addiction histories endure pain that would be treated in other patients.  Father than singling out some patients for ‘special non-treatment,’ we should prepare for the risks from opioids in ALL patients—a set of ‘universal precautions for opioid treatment,’ similar to the way we use a different set of universal precautions to avoid transmission of blood-borne infections.

There are times when doctors have to tolerate being the bad guys.  Some patients have been taught, through careless prescribing, that all pain should be treated with narcotics. Those patients are not happy when told, after paying several hundred dollars, that they do not ‘need’ narcotic pain medication– and so many of their doctors have a hard time saying ‘no.’ After all, doctors studied hard to do well in school, and usually receive praise for what they do. It is much easier to write a prescription and hear ‘thank you’ than to be called an unsympathetic jerk! But doctors are paid the big bucks to tolerate such things, and to keep the long-term health of patients in mind. And for many people with chronic pain, opioids will provide a good month or two, but for the price of many years of misery.

I’ve been told by patients “I don’t care about the risks, doc– I’d rather have three good months and then die, then have twenty years in pain.” I reply, “that’s why these medications require a doctor to consider things very carefully, and a good doctor would not allow someone to make that decision.” I’m sure that some people will be angered by that attitude. But the approach is similar to how we handle many other illnesses, where we encourage patients to tolerate short-term misery for long-term benefits. Many patients would refuse chemotherapy and give up on life if not pushed to move forward. And to depressed patients, suicide can appear a reasonable option. I’m a fan of free will, but I recognize that we don’t always choose our paths through life with full insight.

Even with full knowledge of the reasons to avoid narcotics, some doctors really struggle over withholding opioids.  I find it somewhat ironic that the doctors who are too ‘kind-hearted’—i.e. who want to please patients so much that they cannot deny even that which is bad for them—are the ones who end up getting into trouble.  The Iowa doctor is being sued over several of the deaths, likely by relatives of the patients who pled the hardest for pain pills!  Talk about good deeds not going unpunished!

But there are aspects of the case in Iowa that do not argue well for the doctor. Several of the patients who died were only seen once, but treated with narcotics for years. The DEA requires that patients are prescribed no more than 90 days of narcotic medication at one time (divided on three monthly prescriptions). I presume that patients were picking up scripts every three months, without having appointments each time. Such a practice is not strictly illegal (not that I am aware of, anyway), but the standard of care would be to evaluate patients on potent opioids every three months, or even more frequently. And one news article stated that the doctor had tens of thousands of pain patients. As a full-time practitioner with less than 1000 patients, I wonder how so many patients could be managed by one physician.

When I write about this topic I receive angry comments from some readers. Some attack me personally with comments like “I’m glad I’m not YOUR patient!” or “I hope YOU have to suffer with horrible pain some day!” I realize that this is a very hot topic, and my only intent is to educate and inform, to help people understand what is happening in the minds of physicians. Of course, the care of patients should not be determined by the need for doctors to protect their own interests. But at the same time, it is understandable that doctors are affected by headlines announcing the imprisonment of other doctors facing the same treatment decisions.

Bottom line– there are very good reasons to avoid using opioids for nonmalignant chronic pain. Just giving patients what they want, and ignoring the danger of opioids, will likely result in criminal and civil prosecution. But that reason is secondary to the most important thing– the promise all doctors make to first, do no harm. And patients should realize that their doctors may be withholding narcotics for that reason alone.
