Some medications help patients in several ways — such as how an aspirin for a fever may also lower heart attack risk — but that isn't always the case. A medication for cholesterol once thought to improve bone health probably doesn't do so, a new study found.

Statins, a type of medication used to lower cholesterol, recently underwent some label changes. This caused some confusion about a potential association with cognition problems, including short-term memory loss.

Osteoarthritis and high cholesterol may seem like totally unrelated conditions. But as it turns out, the same medicines that lower cholesterol may also help prevent osteoarthritis. 

Some medications used to treat high cholesterol, like Lipitor or Caduet , were linked to some cases of myopathy , a muscle wasting disease.
