Provigil is the original branded modafinil, developed by Cephalon. Generic modafinil – sold under names like Modalert, Modvigil, and others – is chemically identical. The only meaningful difference is price. Here’s what UK buyers need to know.
What Is Provigil?
Provigil is the brand name for modafinil, originally patented by Cephalon (now owned by Teva). It was approved for narcolepsy, sleep apnoea, and shift work disorder. In the UK, it’s available on prescription and dispensed by licensed pharmacies. It is expensive.
What Is Generic Modafinil?
When Provigil’s patent expired, other manufacturers were permitted to produce their own versions of the same molecule. The most well-known generics available in the UK are:
- Modalert 200mg – Sun Pharmaceuticals
- Modvigil 200mg – HAB Pharma
- Modalert 100mg – same manufacturer, lower dose
These are manufactured to the same pharmaceutical standards as Provigil. The active ingredient, dosage, and mechanism of action are identical.
Provigil vs Generic Modafinil: Price Comparison
Branded Provigil on private prescription in the UK can cost £3-£6 per tablet or more. Generic modafinil from an online pharmacy typically costs £1-£2 per tablet, less in larger quantities.
Is Generic Modafinil as Effective as Provigil?
Yes. The active ingredient is the same molecule. Some users report minor differences in onset time or subjective feel between brands, but this is likely due to inactive excipients rather than the active compound. Clinical effect is equivalent.
Why UK Users Choose Generics

- Identical active ingredient and mechanism
