Mercaptopurine Tablets

Class II — Moderate risk. May cause temporary or reversible harm; serious harm unlikely.

Why it was recalled

Failed USP Dissolution Test Requirements: This sub-recall is in response to Prometheus Laboratories Inc. recall for Mercaptopurine USP 50mg because the lot does not meet the specification for dissolution.

Cause type: Dissolution failure

The tablet or capsule did not dissolve within specification. Dissolution controls how much drug the body absorbs; a failure can change the effective dose. All dissolution failure recalls.

Check, then ask. Class II means harm is possible but usually temporary or reversible. Find the lot number on your package; if it matches, ask your pharmacist about a replacement. Do not simply stop a prescribed medication on your own - the gap can be riskier than the recall. This recall is now terminated, which means the firm has finished removing the affected product; anything on pharmacy shelves today should be unaffected.
