WHAT HAPPENED

The Japan Consumer Affairs Agency has published a recall notice for “New Rikokode Tablets” (新リココデ錠) manufactured by Zeneru Yakko Koka (ゼネル薬工粉河).

This issue may affect the product’s stability and efficacy over time, prompting the company to initiate a voluntary recall. The recall began on June 22, 2026, and is being conducted in coordination with the Pharmaceuticals and Medical Devices Agency (PMDA).
