Common use

Vilafinil is primarily indicated for the treatment of excessive daytime sleepiness associated with narcolepsy, obstructive sleep apnea/hypopnea syndrome, and shift work sleep disorder. Off-label applications include adjunctive management of attention deficit disorders and fatigue associated with medical conditions. The medication is typically prescribed as part of a comprehensive treatment plan that includes behavioral modifications and sleep hygiene education. Clinical use requires proper diagnosis and ongoing medical supervision to ensure appropriate therapeutic application.

Dosage and direction

The recommended dosage for Vilafinil is 200mg administered orally once daily, typically in the morning. For shift work sleep disorder, the dose should be taken approximately one hour before the work shift begins. Treatment initiation should start at the lowest effective dose, with titration based on individual response and tolerability. The tablets should be swallowed whole with water and may be taken with or without food, though consistent administration relative to meals is recommended. Dosage adjustments in special populations require careful medical consideration.

Precautions

Patients should be monitored for the development of hypersensitivity reactions, including serious skin rashes. Cardiovascular status should be assessed before and during treatment, particularly in those with pre-existing hypertension or arrhythmias. Psychiatric symptoms including anxiety, agitation, and insomnia should be carefully evaluated. Caution is advised when operating machinery or performing hazardous activities until the individual response is established. Regular follow-up appointments are essential to monitor therapeutic efficacy and potential adverse effects.

Contraindications

Vilafinil is contraindicated in patients with known hypersensitivity to modafinil or any component of the formulation. It should not be used in individuals with symptomatic cardiovascular disease, particularly those with left ventricular hypertrophy or mitral valve prolapse. The medication is contraindicated in patients with history of psychosis or mania. Concomitant use with monoamine oxidase inhibitors is strictly contraindicated. Pregnancy and breastfeeding represent absolute contraindications without thorough risk-benefit assessment.

Possible side effects

Common adverse reactions include headache (34%), nausea (11%), nervousness (7%), and insomnia (5%). Less frequently reported effects include dry mouth, anxiety, dizziness, and gastrointestinal disturbances. Serious but rare side effects may include Stevens-Johnson syndrome, angioedema, multiorgan hypersensitivity reactions, and psychiatric symptoms including depression and suicidal ideation. Cardiovascular effects such as hypertension, tachycardia, and palpitations have been reported in susceptible individuals. Most side effects are dose-dependent and often diminish with continued therapy.

Drug interaction

Vilafinil demonstrates complex pharmacokinetic interactions due to its effects on cytochrome P450 enzymes. It may reduce the efficacy of oral contraceptives, requiring alternative contraceptive methods. Concurrent use with CYP3A4 substrates (cyclosporine, triazolam) may require dosage adjustments. The medication may potentiate the effects of sympathomimetic agents and MAO inhibitors. Concomitant administration with warfarin may necessitate increased monitoring of coagulation parameters. Alcohol consumption should be avoided due to unpredictable effects on cognitive function.

Missed dose

If a dose is missed, it should be taken as soon as remembered unless it is approaching the evening hours. Administration late in the day may interfere with nighttime sleep. The missed dose should not be doubled to make up for the forgotten dose. Patients should maintain their regular dosing schedule the following day. Consistent daily administration at the same time is recommended to maintain stable plasma concentrations and optimize therapeutic effects.

Overdose

Symptoms of overdose may include insomnia, central nervous system excitation, agitation, confusion, tachycardia, hypertension, and gastrointestinal disturbances. In cases of significant overdose, cardiovascular effects may become pronounced. Management involves symptomatic and supportive care, including cardiac monitoring and appropriate antihypertensive therapy if indicated. There is no specific antidote for Vilafinil overdose. Gastric lavage may be considered if presentation occurs shortly after ingestion. Hospital observation is recommended for significant overdoses.

Storage

Vilafinil tablets should be stored at controlled room temperature (20-25°C/68-77°F) in their original packaging. Protection from moisture and light is essential to maintain stability. The medication should be kept in the provided child-resistant container and stored out of reach of children and pets. Proper disposal of expired or unused medication should follow local regulations for pharmaceutical waste. Tablets should not be transferred to alternative containers that may compromise stability or safety features.
