The cost depends on your insurance company if you have one. Mine negotiates prices based more on their volume. With my insurance, it is cheaper per mg. of oxycodone to get plain 5 mg. tablets than to buy Percocet with 5 mg. of oxycodone in generic form. Higher than 5 mg. of plain oxycodone is hard to come by in our area for some reason, but the 5 mg. tablets are easily available.
The makers of tylenol recently came out and now they are recommending no more than 3,000 mg. per day instead of the 4,000 mg. they used to prescribe. Whenever I have taken oxycodone or hydrocodone mixed with acetaminophen, I have asked for the least amount of acetaminophen possible. I have discussed this with a liver specialist and he said it would depend on the person and what other meds, alcohol they were using. He has suggested to some patients that they could take up to 8,000 mg. per day and others where he suggested they not use it at all.
I have belonged to Medscape professional site for many years. The application is longer than many sites, but no longer than some others.
I had the Internal Medicine updates emailed to me regularly for ages. I found lots of good info pertaining to Migraines, which were a big problem for me at that time, and also for cancer and diabetes updates, common in my family.
I still have it bookmarked for easy access. I really like it for much the same reason as you do, it is not trying to sell anything, and posts mainly peer reviewed journal articles, so you know the erroneous information has been filtered out.
