Common use

Vilafinil is primarily indicated for the treatment of narcolepsy, obstructive sleep apnea (as adjunct therapy), and shift work sleep disorder. Off-label, it is sometimes used to address attention deficit hyperactivity disorder (ADHD) and fatigue associated with medical conditions such as multiple sclerosis or depression, though these uses should be strictly supervised by a physician.

Dosage and direction

The typical dosage for Vilafinil is 200mg taken orally once daily, preferably in the morning. For shift work sleep disorder, take approximately one hour before the start of the work shift. Dosage may be adjusted based on individual response and tolerability, under medical supervision. Do not crush or chew tablets; swallow whole with water. Avoid taking later in the day to prevent insomnia.

Precautions

• Use with caution in patients with cardiovascular disease, hypertension, or history of mental health disorders
• Regular monitoring of blood pressure and heart rate is advised during treatment
• May impair ability to drive or operate machinery; assess individual response before engaging in hazardous activities
• Not recommended during pregnancy or breastfeeding unless potential benefits outweigh risks
• Avoid alcohol consumption as it may exacerbate side effects or reduce efficacy

Contraindications

• Hypersensitivity to Modafinil or any component of the formulation
• History of left ventricular hypertrophy or ischemic ECG changes
• Patients with symptomatic arrhythmias
• Severe hepatic impairment
• Concurrent use with monoamine oxidase inhibitors (MAOIs)

Possible side effect

Common side effects may include headache, nausea, nervousness, anxiety, dizziness, and insomnia. Less frequently, dry mouth, diarrhea, or palpitations may occur. Rare but serious side effects include Stevens-Johnson syndrome, angioedema, or psychiatric symptoms such as hallucinations or aggression. Discontinue use and seek medical attention if severe reactions develop.

Drug interaction

Vilafinil may interact with:

• CYP3A4 inducers or inhibitors (e.g., ketoconazole, rifampin)
• Hormonal contraceptives (may reduce efficacy; alternative contraception advised)
• Warfarin and other anticoagulants (monitor INR closely)
• Cyclosporine, theophylline, and clozapine (dosage adjustments may be needed)
• SSRIs and tricyclic antidepressants (potential increased serotonergic effects)

Missed dose

If a dose is missed, take it as soon as remembered unless it is close to the next scheduled dose. Do not double the dose to catch up. If it is near bedtime, skip the missed dose to avoid insomnia.

Overdose

Symptoms of overdose may include agitation, confusion, tachycardia, hypertension, and insomnia. There is no specific antidote; treatment is supportive and symptomatic. Contact emergency medical services or a poison control center immediately.
