People increasingly use the internet to explore medical issues. That is in general a good thing, provided they are careful about using credible sources for their information and are not too credulous about what they find. Being more knowledgeable about their own health can make for more fruitful conversations with their physicians.
But the old saying ‘a little knowledge is a dangerous thing’ can sometimes kick in and people can decide that they know more than their physician, or indeed the entire medical profession, and demand specific treatments. They especially do this when it comes to ‘off-label’ uses of drugs, when people ask that a drug that has been shown to be effective in treating one condition be used to treat a different condition where its efficacy or even safety has not been established. People sometimes seize upon anecdotes about its use to demand that it be prescribed for them.
