Rumor Vs. Truth

I would like to start a section on my blog called "Rumor Vs. Truth." This column is from a pharmacy newsletter I read called the "Pharmacist's Letter." In each issue, the authors expose about a dozen rumors facing a variety of medications. I will share just a few that I think pertain to over the counter drugs for a broader set of patients.


RUMOR: Colon cleansing and other "detoxification" methods leads to better general health.

TRUTH: This is based on a theory that over time the body accumulates harmful toxins such as metals and pesticides. Proponents believe special treatments including herbals or supplements given orally or as enemas, or special diets are needed to remove these toxins from the body.

But there is NO proof to support any of these theories...or that any special product or method will rid the body of toxins. The kidneys and liver are very efficient at filtering and eliminating toxins from the body.

Detoxification programs often include laxatives. These can cause significant diarrhea resulting in fluid loss and electrolyte imbalances. Some laxatives can even worsen heart failure or cause kidney failure in people at high risk. Enemas or colonics can also cause electrolyte imbalances or a perforated rectum. Extreme changes in the diet can lead to fatigue, diarrhea, or constipation. Long-term fasting can result in vitamin and mineral deficiencies and protein deficiency.
Advise patients to stick to standard measures...a good diet, regular exercise, using bulking agents (psyllium, etc) to stay regular if needed, etc.


RUMOR: Alka-Seltzer can cure a urinary tract infection (UTI).

TRUTH: One very popular home remedy is to use Alka-Seltzer tabs. It's proposed that by alkalinizing the urine, the sodium bicarbonate in Alka-Seltzer will inhibit some types of bacteria from growing in the bladder. But there is no good evidence that alkalinizing the urine helps to relieve symptoms of dysuria...whether due to infection or not. Studies have failed to show any benefit of sodium bicarbonate for treatment of UTIs.

Patients should see a doctor if they are experiencing any symptoms suggestive of a UTI...urgency, frequency, or pain when urinating. An improperly treated UTI can progress to a more serious kidney infection.



RUMOR: Vicks Vaporub applied to the feet can stop a cough.

TRUTH: This has been perpetuated by websites claiming a Canadian study proves that this works. But that’s where the trail turns cold. The group that supposedly published the study denies any knowledge of its existence.

The web is filled with glowing testimonials that this works. And many parents welcome it as an alternative to drugs in children. There’s no proof that this home remedy works. If you still want to try it, wear socks so the oils won’t stain the sheets. Do not dab Vicks in the nose hoping this will work better. The petrolatum in the product can cause a form of pneumonia if aspirated into the lungs.
