The U.S. Food and Drug and Administration says prescription drugs bought on 10 Canadian pharmacies websites have turned up as fakes. The agency said it tested drugs intercepted on the way to American consumers and they turned up counterfeits of 10 popular medications, including the cholesterol drugs Lipitor and Crestor, and the painkiller Celebrex.  "There are lifesaving drugs out there that people can't afford. So, people are looking for alternative places to go and buy them," said David Certner, AARP.
Quoted from Channel 8 News in Las Vegas
"Caveat Emptor" is latin for "Let the Buyer Beware".
If you buy drugs online, test each site with a small purchase first.
Being without health insurance, I'm forced to buy my pharmaceuticals online.
If I have an infection, those little antibiotics that the doctors love to pass out cost over $16 a pill.
For example:
Without insurance. A a prescription of 7 Cipro costs $18. A doctor visit costs $95.
Totaled thats $113. Divide that by 7 and you get $16 a pill.
I just ordered 50 Cirpros for $35 online from an Indian pharmacy. Thats .70 a pill.
Another example:
I'm an asthmatic and it gets really bad here in Las Vegas.
Albuterol inhalers cost me $10 online.
I once saw an invoice where Medicare was billed $120 for just one inhaler.
The bottom line is
If you need prescription drugs, and even if you have insurance, you should still shop around.
It should be like almost everything else in the United States, free enterprise.
Let the laws of supply and demand work for you.
Don't let the insurance and pharmaceutical companies fix the prices.
