How to Avoid Medication Side Effects and Adverse Reactions

Editor’s Note: For 16 years, I've published weekly essays here on Blogspot, which will continue. I’ve now begun publishing my work on a new blogging platform, Substack, and I hope you’ll join me there. Please enter your email address at this link to receive my posts directly to your inbox.

When a medical misadventure or new symptoms develop, physicians will often consider if the event is a side effect of a medication.  This can be very difficult to establish.  For example, if a patient is given medication to treat colitis and the diarrhea worsens, is this a side effect of the medicine or a worsening of the colitis?  

Physicians face these dilemmas all the time.  If a patient develops a symptom, and a side effect is being considered as an explanation, the doctor either knows or researches if there is medical evidence supporting a side effect event in this specific circumstance.  If a patient develops headaches after a new medicine is prescribed, and this symptom has never been reported as a side effect of the medicine, then the drug is likely not the cause.  Of course, just because a side effect has not been reported, does not guarantee that one has not occurred.   As every doctor knows, patients often look up the side effect profiles of their drugs and decide that their nausea, fatigue, and GI symptoms must be drug-related since these symptoms are on the drug’s side effect list.  Good luck finding a drug that doesn’t include nausea as a potential side effect!  It’s a wonder that patients who review the extremely long list of side effects of proposed drugs actually take them!  We’ve all heard the ubiquitous TV drug ads which conclude with rapid-fire recitations of horrendous possible side effects, which often include fatalities.  I’m a doctor, and I get spooked listening to these lists! 


Even common aspirin can cause serious side effects.


Thankfully, most medicines cause either no side effects or only mild ones.  Deciding if a side effect is even present can be challenging.  Physicians may opt to discontinue a drug, not knowing for certain if the medicine is the culprit.  This is not always a clean exercise, as some side effects can linger on for weeks or longer. 

Here’s an effective strategy to minimize your risk of developing drug side effects.  Advocate for yourself.  Is the proposed medicine absolutely necessary?  Is there a safer drug available?  Are you prescribed the lowest dose necessary?  The rocket fuel for medication side effects is the disease of polypharmacy, which is raging out of control.  How long is your medication list?   Are several different physicians and medical professionals prescribing your drugs? Are all of them truly necessary?   Is there a primary care physician in charge to whom the consultants are accountable? Is there a medical professional assessing with some regularity the continued need for all of your medicinal potions?

Stop Medical Malpractice: The White Coat Wall of Silence

Photo Credit Leisure Guy, one of my most faithful commenters, opines that I am omitting an important aspect of the tort reform argument. He has implored me repeatedly to read a particular book that I suspect buttresses his views, but this worthy pursuit is simply not near the top of my priority pyramid. Since he’s retired, he enjoys the luxury of burrowing deeply into the base of his priority pyramid. With 4 tuitions to go, retirement is a distant mirage for me. I’m can be a ‘leisure guy’, but only in my dreams. I have written throughout this blog and elsewhere that there are too many frivolous lawsuits against physicians. I have admitted that caps on non-economic damages are not ideal, because they deny some worthy plaintiffs of complete compensation, but I support them because I believe they serve the greater good. I have ranted that there is no effective filter to screen out physicians who should never be invited to the litigation party in the first place. I believe that the...

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 ...

Will Smarter Lawyers End Frivolous Lawsuits?

How do you know if a lawyer is any good?  Of course, they've all passed the bar, but now their profession is lowering it.  While most of us strive for excellence, and raise our children to value this virtue, prominent legal educators are establishing a new quality intitiative for their profession.  Who says that lawyers can't reform themselves?  Perhaps, we physicians can follow their bold example and raise the credentials of our pre-medical students.  I’ll present the facts. You be the judge. I have written a dozen posts on tort reform on this blog, which always generate spirited and adversarial retorts from attorneys and their supporters. They accuse me and other tort reform advocates of carrying water for insurance companies. They repeatedly point out that I know nothing about the legal system and are unqualified to opine on its flaws. They deride me when I argue that effective tort reform would reduce the practice of defensive medicine, despite the re...
