Is it safe to take crestor (rosuvastatin) 10 after the expiration date of 4-20016 how often should you get a liver test when taking crestor (rosuvastatin) 10?

Not a good idea: to make a "habit" out of taking EXPIRED medication but chances are there is no harm or loss of strength a month or so beyond the expiration date. The FDA requires that the date used is CONSERVATIVE!!!!! Liver Function should be measured each time you have your LIPID tests are done! The FIRST set should be no later than 4 weeks after starting! Hope this helps! Dr Z
