Bottom line
- Provigil is simply the brand name for modafinil.
- The only real differences are price, packaging, and the specific inactive ingredients used by each manufacturer.
- Clinical effectiveness, pharmacokinetics (half‑life ≈ 15 h), and safety profile are the same.
- If cost is a factor, the generic is usually the better choice—no loss in therapeutic benefit.
- Some patients or providers prefer the brand because of familiarity, but that is largely a matter of preference, not medicine.
