Modalert and Modvigil are brand names for products that generally contain modafinil. Modalert is commonly manufactured by Sun Pharma, while Modvigil is commonly associated with HAB Pharmaceuticals.
Products with the same stated dose may differ in:
- Manufacturer and manufacturing facility
- Inactive ingredients, coating and tablet appearance
- Packaging, available strengths and price
- Regulatory approval and quality documentation
- Individual tolerability and response
The active ingredient may be the same, but that does not guarantee an identical effect for every person. Modafinil is a prescription medicine and may cause side effects or interact with other medicines. A doctor or pharmacist should help determine whether a particular product and dose are appropriate.
