Methenamine hippurate (Hiprex) tablet: New packaging

New look Active

There is a packaging change for the Hiprex tablets, with a new Pharmacode. This reflects its new status as a "pharmacist only / restricted" medicine.

What's changed

On 1 December 2024, Hiprex tablets changed from "general sale" to a "pharmacist only / restricted" product. This was a Medsafe decision.

Pharmac funded the new Hiprex packs from 23 January 2024 (Pharmacode 2671077). The old packs, with Pharmacode 209538, will be de-listed on 1 July 2024.
