Tablets may be swallowed with water and can be taken with or without food. Avoid late-day dosing if you experience insomnia. Do not change the dose or frequency without discussing it in concert with your clinician.
Special groups:
- People with liver impairment may require lower doses because modafinil clearance is reduced.
- Older adults or frail patients are usually started at a lower dose and monitored more closely for deleterious effects.

Hazard controls and preventive precautions and important notes
Before the start modafinil, inform your prescriber about medical conditions, other medicines, and life circumstances that may affect safety or require dose adjustments. Relevant issues include:
- Significant liver disease, which may necessitate dose reduction
- The medical term diabetes, because appetite or glucose control can change
- Cardiac disease such as uncontrolled hypertension, arrhythmias, or structural heart problems
- Bleeding disorders or concurrent anticoagulant therapy
- Existing psychiatric disorders including anxiety, bipolar disorder, psychosis, or a history of suicidal thoughts
- Pregnancy or breastfeeding — modafinil is generally avoided unless benefits clearly outweigh risks
- Women using combined hormonal contraception — modafinil can reduce contraceptive effectiveness; use non-hormonal backup and continue it for at least two months after stopping modafinil

- Hormonal contraceptives: reduced effectiveness; use a reliable non-hormonal method while taking modafinil and for two months after stopping
- SSRIs (for example fluoxetine, sertraline): may need supervision and monitoring and within the realm of possibility dose changes
- Azole antifungals and other strong CYP modulators: people engage through a series of the reciprocal contact between individualss. are drug-specific and may be significant
- Warfarin and similar anticoagulants: INR can be affected; check levels after starting or stopping modafinil
- Strong enzyme inducers (phenytoin, carbamazepine, rifampicin): these can lower modafinil exposure
- Drugs metabolised by CYP2C19 (omeprazole, diazepam): concentrations may rise or fall
- Dopaminergic or stimulant drugs: additive central effects; monitor for overstimulation
- MAO inhibitors: avoid combining unless under specialist oversight
When starting or stopping modafinilplease take a look and check. whether tracking and monitoring of performance or dose adjustments of other medicines are needed. Talk to your pharmacist for drug-specific advice.
Skipped medication administration and timing advice
If you do not take a dose, take it at once after you remember, unless the next dose is due soon. If taking a late dose would interfere with sleep, skip the missed medication dose and continue your normal schedule. Do not add a second tablet to make up for a missed medication dose.
For shift work dosing, if the pre-shift dose is forgotten besides the shift is already underway, contact your prescriber because taking the dose late may disrupt subsequent sleep or recovery.
See dosing strategy guidance for timing related to shifts and mornings.
