When pharmaceutical companies stop making a pill that has worked great for many years.
What an upset to those of us who use said meds. Yesterday I looked high and low for my favorite antihistamine, only to find the company is no longer making the product. Say what? I searched on line, and Amazon had the product but for over $25 a box, a box which couple months ago only costed me $4.99 at Target. Oh how I hate to experiment with new antihistamines :(
Another example, a few years ago Pfizer stopped making a anti-veritgo medicine called Anti-Vert which worked beautifully. My late Mom, who was in her 90's, said it worked wonders for her not feeling dizzy. Poof, off the market. We tried the generic but it didn't work as well. I called every drug store in the area, found a couple of pharmacies that had the discontinued product, and made a mad dash with Mom and mine prescriptions.
I realize that drug companies have patents on their pills, and that patents ends, thus other companies can make the generic. You'd think it would be the same, but it all depends on what fillers are used in the pill to make it large enough to handle, such as lactose.. what binders are used to keep the pill together... and what coatings are used to make the pill stay whole while traveling to the stomach. All it takes is one filler, or one binder, or coating that someone cannot tolerate to mess up the whole thing. Grrrrrr.
