What is the brand name of vigabatrin?

In the US, the original brand is Sabril, sold as 500 mg tablets and 500 mg powder packets since 2009. Vigafyde is a newer brand, approved in 2024, and is a ready-to-use liquid. Vigadrone and Vigpoder are generic versions, and several other companies make generics.

Is Vigadrone the same as Sabril?

Vigadrone is a generic vigabatrin powder for oral solution, approved in 2018. It comes in 500 mg packets in cartons of 50 and is mixed the same way as Sabril powder: 10 mL of water per packet, made fresh for each dose.

Is there a generic of Vigafyde?

In FDA records checked in October 2026, Vigafyde was the only ready-to-use vigabatrin solution. All generic vigabatrin products were powder packets or tablets.

Do all vigabatrin brands carry the vision-loss warning?

Yes. Every vigabatrin product contains the same medicine, carries the boxed warning about permanent vision loss and is available only through the Vigabatrin REMS program.

Sabril

Sabril is the original brand name. Its tablets and its powder for oral solution were both approved on 21 August 2009. The application holder is Lundbeck.¹

Tablets: 500 mg, film-coated and scored, in bottles of 100.⁵ See tablets.
Powder for oral solution: 500 mg packets, 50 to a package. Each dose is mixed with 10 mL of water per packet, used straight away, and the rest thrown out.⁶ See powder sachets.

The powder is labeled for infantile spasms from 1 month to 2 years and, as an add-on treatment, for refractory complex partial seizures from age 2.⁶

Vigafyde

Vigafyde is a ready-to-use oral solution, 100 mg per mL, approved on 17 June 2024. The application holder is Pyros.² It comes in a 150 mL bottle, needs no mixing, and is kept for up to 90 days after opening.⁴

Vigafyde is labeled only for infantile spasms in babies 1 month to 2 years old. It is not approved for refractory complex partial seizures or for adults.⁴ Its approval was based on comparing its composition with vigabatrin powder solution, not on new efficacy trials.⁴

In the FDA's records, Vigafyde was the only vigabatrin product listed as a ready-to-use solution. Every generic was a powder or a tablet.³

Because it is twice as concentrated as mixed powder, the same number of mL gives twice the dose. The label warns prescribers, pharmacists and caregivers to check the volume when switching.⁴

Vigadrone

Vigadrone is a generic vigabatrin powder for oral solution, approved on 21 June 2018 under ANDA 210196. DailyMed now lists Upsher-Smith as its labeler.³ It comes in 500 mg packets in cartons of 50, and it is mixed exactly like Sabril powder: 10 mL of water per packet, 50 mg per mL, each dose made fresh and the rest discarded.⁷

A 2025 lab study by the powder's makers found Vigadrone stayed stable for 48 hours in the fridge when mixed in water, juice, milk or formula. The label still says water only.⁸

Vigpoder and other generics

Vigpoder is a generic vigabatrin approved under ANDA 214961; the application holder is Pyros. Teva, Amneal, Dr. Reddy's, Zydus and others hold approvals for generic vigabatrin powder packets or 500 mg tablets.³

What generic means here

A generic is approved through an abbreviated new drug application (ANDA). It contains the same active ingredient, vigabatrin, in the same 500 mg strength as the brand product it copies.³ Generic and brand powders are mixed the same way.^6,7 Which product you receive can depend on your insurance and pharmacy; see cost.
