Your doctor would not put you on it for low HDL (
good cholesterol) as it does not increase HDL, it lowers LDL
or bad cholesterol. Do you know what your breakdown was?
In any case, statins are very safe and proving to me more safe all the time. The risk of any side effect is anywhere between 2% and 5% which classifies this as very safe. Common side effects are muscle pain and sore joints. I would take it and just keep an eye out for anything that may be a side effect.
