Commencing 1 September 2024, a new brand GABAPENTIN-WGR was added to the listing 1835N - gabapentin 400 mg capsule, 100.

The ‘a’ flag indicating substitutability with other brands listed on this item was inadvertently not applied to the new GABAPENTIN-WGR brand. This brand will not be substitutable with the alternate brands for 1 September 2024. This will be corrected in the 1 October 2024 PBS update to allow substitution for this brand.
