Alliant Pharmaceuticals issued a nationwide recall on January 14, 2005 of about 2800 bottles of the drug Methylin, used to treat attention deficit hyperactivity disorder, also known as ADHD, and narcolepsy. The lot number, AMT50402A, has an expiration date of April 2006 and may contain as much as three times the active ingredient it should.

The company sent letters to doctors and pharmacists to ask them to notify patients who may have received a dispensation of the drug from a provider with bottles from the defective lot.

If you have any questions about a prescription dose of Methylin you may have recently received, you are advised to speak with your pharmacist or medical doctor immediately. It is not advised to stop taking any prescription medication without the advice of a physician.
