In the rest of the world there are not the restrictions on drugs that are found in the USA.
I have lived overseas long enough that I have been treated by licensed medical doctors in another country, who prescribed to me drugs that are not permitted in the United States. That was not a happy experience. I eventually had to have FDA-approved drugs that ACTUALLY WERE SAFE AND EFFICACIOUS sent over to me as I continued my stay in that country. There are prescribing and dispensing biases in other countries that frequently cause the most safe and effective medicines to not even be available in those countries at any price, even long after FDA approval of the best medicines in the United States.
