1. What it is

Term	Detail
Brand name	Provigil
Generic	Modafinil
Drug class	Wake‑promoting agent (also called a “cognitive enhancer”)
Form	Tablet (usually 100 mg or 200 mg)
Approval	FDA‑approved for narcolepsy, obstructive sleep apnea (when used with a CPAP machine), and shift‑work sleep disorder.

---

2. How it works

• Exact mechanism unknown – it is thought to affect several neurotransmitter systems in the brain (dopamine, norepinephrine, orexin, etc.), thereby increasing alertness.
• It does not work like stimulants (e.g., amphetamines). The risk of addiction is lower, but it can still be habit‑forming when taken for non‑medical reasons.

3. Typical uses

Condition	Why it’s helpful	How it’s taken
Narcolepsy	Stops or reduces sudden daytime sleep attacks.	Usually 100 mg once daily in the morning.
Obstructive Sleep Apnea (OSA)	Helps keep you awake during the day when you are using CPAP at night.	100 mg once daily, or 200 mg if the patient is on CPAP.
Shift‑work sleep disorder	Keeps workers alert during night or irregular shifts.	200 mg 30‑60 min before the shift starts.

4. Typical dosage

• Starting dose: 100 mg once daily in the morning for most patients.
• Titration: 100 mg can be increased to 200 mg if needed (usually 200 mg once daily, or split as 100 mg before work and 100 mg after).
• Timing: Take in the morning (for narcolepsy) or 30–60 min before the shift (for shift‑work). Avoid taking late in the day— it can interfere with nighttime sleep.

Always follow your doctor’s prescription. Dosage adjustments are rarely needed for most patients.

6. Serious risks & contraindications

Risk / Contraindication	Details
Heart problems	Modafinil can increase heart rate and blood pressure; not recommended for severe cardiac disease.
Severe liver disease	Reduced drug clearance; avoid.
Pregnancy	Limited data; use only if benefits outweigh risks.
Breastfeeding	Excretion into breast milk; generally avoided.
Mental illness	Can worsen psychosis, mania, or severe anxiety.
Drug interactions	CYP3A4 inducers (e.g., carbamazepine, rifampin) reduce levels. CYP3A4 inhibitors (e.g., ketoconazole) increase levels.

7. Drug interactions (not exhaustive)

Drug	Effect on modafinil	Effect on the other drug
CYP3A4 inducers (carbamazepine, phenobarbital)	Lowers modafinil concentration → less efficacy	Modafinil may not be fully effective
CYP3A4 inhibitors (ketoconazole, erythromycin)	Raises modafinil concentration → higher risk of side effects	Potential increased exposure to inhibitor
Antidepressants (e.g., fluoxetine)	Can alter serotonin levels; watch for serotonin syndrome	Modafinil may increase antidepressant side effects
Nicotine	Slightly increases metabolism of modafinil	May reduce efficacy
Alcohol	Additive sedating effects	Should be used with caution

8. Lifestyle & safety tips

1. Take it on an empty stomach? With or without food – it’s usually fine, but food can slow onset slightly.
2. Avoid driving or operating heavy machinery until you know how the drug affects you, especially if you’re new to it.
3. Keep a sleep diary: Track how well you stay alert, and any nighttime sleep issues.
4. Use a regular sleep schedule: Modafinil doesn’t replace healthy sleep hygiene.
5. Never share your prescription or take someone else’s dose. The risk of adverse reactions increases with higher doses.
6. Report new or worsening symptoms (e.g., chest pain, severe anxiety, skin rash) to your clinician promptly.

• You notice psychiatric changes: agitation, hallucinations, suicidal thoughts.
• You develop a severe skin rash or blistering.
• You have heart palpitations, chest pain, or high blood pressure.
• You’re pregnant, nursing, or planning a pregnancy.
