Virtually every medication dispensed by US pharmacies seems to be made in India. Pharmacies large and small all seem to get their medications from Indian pharmaceutical companies. I recently had to have a prescription filled for an antibiotic. I called every pharmacy in my city of 235,000 people. Not one had a medication made anywhere other than India. The quality is definitely not the same. I had been taking a maintenance medication for years without incident. When my pharmacy substituted an Indian-made brand without my consent or knowledge, I had terrible side effects. I now refuse all medications made in India unless it's something I need urgently.

Sanitation, or the lack thereof, is a big problem in Indian pharmaceutical companies. Here is an interesting article from the New York Times:

Years ago, 60 Minutes on CBS had a startling report on the lack of sanitation in Indian drug manufacturing facilities. If people have no means to wash their hands after using the toilet, do you really want to take medications that they have made?
