Allergan warned on acne drug promotion

An Allergan Inc advertisement for acne drug Aczone “grossly overstates” the drug’s effectiveness, U.S. regulators said in a letter released on Friday.

The Food and Drug Administration also said the medical journal ad left out “important risk information” and “misleadingly suggests that Aczone is safer than has been demonstrated,” the Food and Drug Administration said.

Allergan spokeswoman Caroline Van Hove said the ad ran in March, April and May and is no longer in use.

A new ad “which addresses the key concerns in the FDA letter” started running in May, she said.
