Stock of the s29 800 mg alternative has run out at the supplier level. A delivery of the registered 800 mg Asacol brand tablets is planned in August 2024. There is enough stock of the 400 mg tablets to cover until the 800 mg is resupplied. We have received clinical advice that people can take two 400 mg tablets of mesalazine.
