Yesterday, Pfizer announced it would give a year’s worth of drugs to people unemployed since January 1, and who have taken Pfizer drugs for at least three months. The rational: the company likely wants to keep its market share while helping those in need. Doesn’t sound like a bad idea on the surface, until you consider a few of the drugs that are up for the taking including the top-selling drugs Lipitor, Viagra and Celebrex.

Lipitor is the most-prescribed drug in the U.S., but it’s also one of the more costly drugs to treat high cholesterol at $101 to $145 for a month’s supply. For those with mild to moderate high cholesterol (people who need to lower their "bad" LDL cholesterol by less than 30 percent), Consumer Reports Best Buy Drugs has long-recommended generic Lovastatin that costs between $18 and $45. Many big-box retailers like Walgreens offer a 90-day fill for about $4 a month or less.

Celebrex is generally used to treat osteoarthritis, but according to hundreds of medical studies, Celebrex doesn’t work any better than any other drug in this category (NSAIDs—Non-Steroidal, Anti-Inflammatory Drugs). An average dose of ibuprofen, naproxen or diclofenac is just as effective as Celebrex. And Celebrex, is a drain on the wallet too at up to $296 for a month’s supply .

And Viagra, well, the jokes are all there, ready for the taking.
