Using a computer program, scientists analyzed 5,600 drug labels and more than 500,000 labeled effects. They found that the average drug comes with a list of 70 potential reactions, according to researchers.
In fact, the more commonly prescribed drugs averaged around 100 side effects each, with some drugs containing as many as 525 listed reactions.
“The greatest number of side effects was found in antidepressants, antiviral medications and newer treatments for restless leg syndrome and Parkinson's disease. In general, medications typically used by psychiatrists and neurologists had the most complex labels, while drugs used by dermatologists and ophthalmologists had the least.”
