Interesting question and the answer is, it appears that they may not be as good as the manufacturers would have you believe. It seems recent studies are actually indicating that the new hot shot kids on the block are nowhere near as effective as some of the dear old standbys. And the best thing is, they cost a great deal less as well. Can’t beat that!
Just because you saw a new drug on TV does not mean you need to rush to your doctor and ask for it. This isn’t like an ice cream flavor of the month, not to mention it will cost you more to get the latest drug as well. Ask yourself if you REALLY need the drug or are mostly just curious; and while you’re at it, ask the doctor if something else a lot less expensive will work just as well at a fraction of the price. This is smart consumerism in action.
