Class III — Low risk. Unlikely to cause harm, but violates FDA regulations.

Why it was recalled

Failed Dissolution Specifications: Sirolimus Oral Solution recalled due to lot RZ1598 exceeded the specification limit at the 14-month timepoint.

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.

FDA recall number
D-0881-2022 · FDA notice

Low risk, still worth a check. Class III means the product is unlikely to cause harm but breaks an FDA rule (often labeling). If your lot matches, your pharmacy will normally swap it; there is no need for alarm. This recall is now terminated, which means the firm has finished removing the affected product; anything on pharmacy shelves today should be unaffected.
