Does Milk Impact Nuvigil (Armodafinil)?
No, milk does not impact the efficacy or absorption of Nuvigil (armodafinil)—there is no documented food-drug interaction between milk and armodafinil, and it can be taken with or without food.
Evidence Base
The available clinical guidelines and research studies do not identify any interaction between milk (or dairy products) and armodafinil. The American Academy of Sleep Medicine's comprehensive 2021 clinical practice guideline for treatment of central disorders of hypersomnolence makes no mention of food interactions, milk restrictions, or dietary considerations when recommending armodafinil for narcolepsy treatment 1.
Clinical Pharmacology Considerations
- Armodafinil is the R-enantiomer of modafinil with a half-life of 10-15 hours, and its absorption characteristics do not require specific timing relative to meals 2
- Clinical trials establishing armodafinil's efficacy (150-250 mg daily) did not impose dietary restrictions or identify food-related efficacy changes 3
- Long-term tolerability studies extending beyond 12 months showed consistent efficacy regardless of administration timing relative to meals 4
Important Drug Interactions to Monitor
While milk is not a concern, clinicians should be aware of these documented interactions:
- Oral contraceptives: Armodafinil reduces the effectiveness of hormonal birth control, requiring alternative contraceptive methods 1, 5
- Pregnancy risk: Animal data suggest potential fetal harm, with a 2018 pregnancy registry showing higher rates of major congenital anomalies in exposed infants 1, 5
- Schedule IV controlled substance: Monitor for potential abuse or dependency 1, 5
