Action Level Retail
Hazard Classification Class III
Reason for the Action Following a customer complaint regarding the darkening of Topiramate, MEDISCA conducted analytical testing of stock on hand. Testing results revealed an Out of Specification (OOS) for the following:
Assay – 97.0% (Specifications 98.0% - 102.0%)
Fructose 0.9% (Specifications 0.3%). This OOS has resulted in an OOS for Total impurities within the product.

According to some scientific literature, Medisca believe that the threefold increase in fructose levels in the product is unlikely to cause any harm to patients. However, there is a quality problem with the product.

This recall does not apply to any other lots of Topiramate or any other Medisca products.

The affected Lot 197335 has been distributed to customers since May 2024.
Instructions for Customers/Users Customers are to:
- Destroy affected stock and provide evidence of destruction to Medisca.
-Alternatively, return affected stock to the sponsor for distruction.
