Another reason to be careful...
Other countries (including India) sometimes have the same name for a completly different drug with the same name here in the states. I wish I could remember some of the names, but I have a hard enough time remembering the names of what I take!
But for example, say a drug is called Goldenoxadyl, and you take it here in the states to treat a heart condition. You find the same name drug from a pharmacy outside of the U.S. for cheaper so you buy it - but, in the country it was made, Goldenoxadyl is a comletly differenct medicine that is used to treat kidney disease. Or perhaps it does treat your heart condition, but it has a different chemical makeup, so you experience unusual (or fatal) side effects.
There are so many reasons why you need to be careful with prescriptions outside of the states - if you do, read the medication insert VERY carefully to make sure it in fact the same drug treating the same condition at the same dose.
