The duration Modafinil (Modalert) stays in your system varies based on factors like dosage, metabolism, and individual health. On average:
- Half-Life: Modafinil has a half-life of about 12–15 hours, meaning it takes this time for half of the drug to be eliminated from your body.
- Complete Elimination: It typically takes 2–4 days for Modafinil to fully leave your system.
Factors Influencing Duration:
- Metabolism: Faster metabolisms may clear the drug sooner.
- Age & Weight: Older individuals or those with higher body fat may process it slower.
- Hydration & Activity: Staying hydrated and active can influence excretion rates.
For drug tests, Modafinil may be detectable in urine or blood for 48–72 hours after use. Always consult a healthcare provider for guidance on usage and effects.
