This may not mean that the drugs themselves are safe, but they may advertise them as a remedy for certain conditions that they haven’t yet been tested on. Evidently, doctors are allowed to prescribe medication that hasn’t been approved to treat certain conditions in what is known as “off-label.” Although this seems like bizarre practice, it is actually fully legal and not that uncommon.
In fact, currently, one in five drugs prescribed to people are for off-label use, meaning that they are used for something other than the drug was originally intended for.
There are several larger and common examples of this. For instance, anti-malarials, like Plaquenil, were clearly invented to reduce one’s chance of developing malaria in a country where the disease is prominent. However, researchers have found that it also treats disorders like lupus and other autoimmune diseases.
