Are Medical Foods FDA Approved?

I was recently queried on a product called Deplin, which claims to have anti-depressant effects when added to a conventional anti-depressant.  Not surprisingly, as a gastroenterologist, I have never prescribed this, although a psychiatrist I contacted has never prescribed it either.

Although a prescription is required, Deplin is not classified as a drug by the Food and Drug Administration (FDA).  It is labeled as a medical food, an important distinction that the public should be aware of.

Years ago, a medical food product, EnteraGam, was introduced as a ‘treatment for diarrhea.  This is when I first became acquainted with the medical food designation.

Let me offer readers some 'medical food' for thought.

The FDA does not assess medical foods as they do for conventional drugs and medical devices.  The prescription drugs that you are taking have passed through years of intense testing under the scrutiny of the FDA, whose approvals means the medicines are both safe and effective.  It is common for drug candidates to fail to gain approval for any of a number of reasons.  Often, the FDA may ask drug companies to conduct additional studies to bolster the case for approval.


Deplin - No Approval Needed!

Medical foods are not considered drugs and, therefore, undergo no such testing as detailed above.  These agents are foods intended to confer a health benefit for a medical condition under the supervision of a physician.  They do not undergo any premarket FDA approval process for medical efficacy.

So, while I can’t categorically deny that medical foods offer benefit, they come to market without FDA approval or any scientifically robust demonstration of efficacy.  Deplin, with purported antidepressant properties, is basically a form of the common vitamin folate, which is available over the counter. 

For me, the claims of medical foods are a little hard to swallow.  Heavy on marketing and light on evidence.

Becoming a Part-Time Physician

Next month my schedule will change.  I will henceforth be off on Fridays with my work week truncated to Monday through Thursday.   I am excited to be enjoying a long weekend every weekend.  And while the schedule change is relatively minor, this event does feel like an important career moment for me.  It is the first step on a journey that will ultimately lead beyond my professional career.  It is this recognition that makes this modest schedule modification more significant than one would think it deserves.  As some readers know,   my current employed position has been a dream job for me.   Prior to this, I was in a small private practice, which I loved, but was much more challenging professionally and personally.   My partner and I ran the business.   Working nights, weekends and holidays were routine for decades.   On an on-call night, if I slept  through until morning, I felt as if I had won the lottery.   And w...

When Should Doctors Retire?

I am asked with some regularity whether I am aiming to retire in the near term.  Years ago, I never received such inquiries.  Why now?   Might it be because my coiffure and goatee – although finely-manicured – has long entered the gray area?  Could it be because many other even younger physicians have given up their stethoscopes for lives of leisure? (Hopefully, my inquiring patients are not suspecting me of professional performance lapses!) Interestingly, a nurse in my office recently approached me and asked me sotto voce that she heard I was retiring.    “Interesting,” I remarked.   Since I was unaware of this retirement news, I asked her when would be my last day at work.   I have no idea where this erroneous rumor originated from.   I requested that my nurse-friend contact her flawed intel source and set him or her straight.   Retirement might seem tempting to me as I have so many other interests.   Indeed, reading and ...

Personal Responsibility for Health

One of the advantages of the computer era is that patients and physicians can communicate via a portal system.  A patient can submit an inquiry which I typically respond to promptly.  It also offers me the opportunity to provide advice or test results to patients.  Moreover, the system documents that the patient has in fact read my message.  Beyond the medical value, it also provides some legal protection if it is later alleged that ‘my doctor never sent me my results’.  I have always endorsed the concept that patients must accept personal responsibility.   Consider this hypothetical example. A patient undergoes a screening colonoscopy and a polyp is removed.   The patient is told to expect a portal message detailing the results in the coming days.   Once the analysis of the polyp has been completed, the doctor sends a message via the portal communicating that the polyp is benign, but is regarded as ‘precancerous'.   The patient is advise...
