Comparison
Armodafinil vs Creatine Monohydrate
Side-by-side of Armodafinil and Creatine Monohydrate. Every row below is pulled from the compound schema and will update as our data grows. For deeper reads, follow through to each compound page.
Armodafinil
Armodafinil is the R-enantiomer sold as Nuvigil. Half-life 10-15 h, 150 mg standard dose, narcolepsy and shift-work approvals, Schedule IV.
Creatine Monohydrate
Creatine monohydrate supplement guide: 3-5 g/day raises phosphocreatine stores, lifts anaerobic output 5-15%, supports lean mass and cognition under sleep loss.
Effects at a glance
Armodafinil
- •FDA approved in 2007 for narcolepsy, shift-work sleep disorder, and OSA residual sleepiness
- •R-enantiomer of modafinil; 150 mg armodafinil is roughly equivalent to 200 mg modafinil
- •Schedule IV controlled in the US; prescription-only globally
- •Longer terminal half-life of about 15 hours produces extended late-day wakefulness coverage
- •Same CYP3A4 induction as modafinil; reduces hormonal contraceptive efficacy
- •Side-effect profile and dermatologic risk warnings mirror modafinil
Creatine Monohydrate
- •Increases anaerobic strength and power output by ~5 to 15% across multiple training studies
- •Adds ~1 to 2 kg of lean body mass over 4 to 12 weeks, partly intracellular water and partly true tissue gain
- •Improves 1-rep max on bench and squat by ~5 to 10% versus placebo in resistance-trained adults
- •Cognitive benefit appears mainly under sleep deprivation or high mental load, less so in well-rested individuals
- •Saturation reached in ~28 days at 3 to 5 g/day, or ~5 to 7 days with a 20 g/day loading phase
- •No evidence of renal harm in healthy adults across long-term studies; caution in pre-existing severe renal disease

Safety profile
Armodafinil
Common side effects
- headache
- nausea
- dizziness
- anxiety
- insomnia (with later-day dosing)
- dry mouth
- mild blood pressure elevation
Contraindications
- recent myocardial infarction
- unstable angina
- left ventricular hypertrophy
- significant arrhythmia
- history of Stevens-Johnson syndrome
- psychotic disorders
- pregnancy
- concurrent MAOI use
Interactions
- hormonal contraceptives: CYP3A4 induction reduces contraceptive efficacy; use barrier method(major)
- cyclosporine: reduced cyclosporine levels via CYP3A4 induction(major)
- warfarin: CYP2C9 inhibition raises INR(moderate)
- phenytoin: CYP2C19 inhibition raises phenytoin levels(moderate)
- MAOIs: potential hypertensive reaction(major)
- classical stimulants: additive cardiovascular and sleep-disruption effects(moderate)
Creatine Monohydrate
Common side effects
- water retention
- mild GI upset at loading doses
- weight gain (2 to 4 lb from intracellular water)
Contraindications
- severe renal impairment
Interactions
- caffeine (high-dose acute): mixed data on ergogenic interference; chronic use appears compatible(minor)
- nephrotoxic drugs (NSAIDs, cyclosporine): theoretical additive renal strain in at-risk patients(moderate)
Which Should You Take?
Creatine Monohydrate comes out ahead for most readers on the criteria we weight: 3 catalogued goals, OTC dietary supplement, oral dosing, with a Tier-A outcome catalogued. Armodafinil is the right call when one of the conditionals below applies.
- → If your priority is wakefulness, pick Armodafinil.
- → If your priority is fatigue resistance, pick Armodafinil.
- → If your priority is strength or hypertrophy, pick Creatine Monohydrate.
- → If your priority is post-training recovery, pick Creatine Monohydrate.
Edge case: If you want to avoid controlled substance, Creatine Monohydrate is the more accessible choice.
Default choice: Creatine Monohydrate. Lower friction to source, a Tier-A evidence outcome catalogued, and broader goal coverage. Reach for Armodafinil only if your priority sits squarely in the goals it owns above.
