In the July 24, 2006, issue of Archives of Internal Medicine
, University of Alabama Medical School researchers and their colleagues describe four cases of individuals with asymptomatic neuromuscular disorders having their conditions precipitated by statin use. It is well known that statins (drugs such as Lipitor
, or Crestor
), used to treat high blood cholesterol, may cause muscle weakness, pain, or cramping. However, in these four cases, taking statins triggered underlying conditions such as myotonic dystrophy
and Kennedy disease
. The researchers suggest that physicians should be aware of this possibility when prescribing statins, and that if neuromuscular symptoms persist after the medication is stopped, further diagnostic evaluation is needed.
