FDA Labeling Announcement for NSAIDS - What does this mean for pregnancy? Recently the Food and Drug Administration (FDA) announced that it is requiring labeling changes for nonsteroidal anti-inflammatory drugs (NSAIDs).

Methanol Toxicity

Methanol, sometimes called wood alcohol, is the simplest of the class of chemicals chemists call alcohols.  Ethanol, the spirit many enjoy in beer, wine, and cocktails, is closely related.  Both can be made naturally when yeast ferment the natural chemicals in grains and fruits.  And like all chemicals, both can be toxic when you are exposed to too much.  But, when you consume methanol, the way your body metabolizes it makes it much more toxic than ethanol.  Methanol poisonings were common during the Prohibition Era of the 1920’s and 30’s because methanol was intentionally added to industrially produced ethanol. This was to prevent bootlegg...

Mixing Cleaners – Just Don’t!

Introduction: Mixing two different cleaning products will double the power to disinfect your home, right?  Everyone knows that bleach kills viruses and bacteria and rubbing alcohol is great at removing grime, so why not mix the two and kill two birds with one stone?  Here is why – many cleaning products contain chemicals that when mixed with each other can form extremely toxic compounds.  According to the American Association of Poison Control Centers, accidental exposures to chlorine gas from mixing bleach and acid occurred 2,284 times in 2017.  This Tox Topic was developed to help you understand why you should not mix cleaning products, what ...

How Safe is this Drug? 

As discussed in its own Tox Topic, and referred to in many others, a fundamental premise of toxicology is that “the dose makes the poison.” This observation dates back almost 500 years ago to the Swiss physician Paracelsus who wrote “The right dose differentiates a poison from a remedy.”  As a physician Paracelsus knew that it was important to not give too much of a drug.  But how much is too much, and how do we help ensure that we have a clear picture of the difference between the dose it takes to provide a benefit and the dose it takes to cause harm? To help do this, we use something called the Therapeutic Index (TI). The Therapeutic ...

What’s a GMO?

Few things spark alarm in enlightened consumers more than the subject of GMO’s—or Genetically Modified Organisms, particularly if related to the food they eat and feed their family.  Because of this fear, consumers can find numerous products sold with a specific label of “GMO-Free” or Non GMO Project Verified.  While an internet  search reveals numerous definitions for GMO, this tox-topic will define them the way many non-scientists think of them.  Specifically, GMO is a term used to describe a plant, animal, or microorganism that has had its genetic material (DNA) altered through a process called genetic engineering (GE).  The US ...
