Rants and Screeds

From July 15, CID

"Not long ago, the cost to the pharmacy at that hospital had suddenly risen from $10 for fifty 100-mg doxycycline pills to a staggering $250 for 50 pills. I cannot trace the reason for this unbelievable jump in price, but occurrences like this have to be part of the problem with the cost of medical care in the United States. Doxycycline is an old generic drug that is the oral drug of choice for Lyme disease as well as other indications; it has been cheap up to now. Someone is taking advantage of the population requiring this drug."

Now that the cost has increased by up to 2000%, many infections can use minocycline instead (Minocycline as A Substitute for Doxycycline in Targeted Scenarios: A Systematic Review).  And as a result, they will probably jack up the price of minocycline as well.
