Vilafinil 400 mg Tablets (Modafinil)

Description

Vilafinil 400 mg Tablets contain Modafinil 400 mg, a prescription wakefulness-promoting medicine used to improve wakefulness in adults with excessive daytime sleepiness associated with conditions such as narcolepsy, obstructive sleep apnea (OSA), and shift work disorder (SWD). Available product listings identify Vilafinil 400 mg as a modafinil formulation manufactured by Fortune Healthcare/Fortune Labs.

Modafinil is a central nervous system wakefulness-promoting agent. It is intended for specific sleep-related disorders and should be used under medical supervision rather than as a general energy, study, or performance-enhancing product. Official prescribing information lists modafinil as a controlled prescription medicine.

Available listings describe Vilafinil 400 mg in 10 × 10 tablet packaging, although packaging can vary by manufacturer, market, and batch. Verify the current physical product label before publishing exact pack information.

Uses and Benefits

Modafinil is indicated to improve wakefulness in adults experiencing excessive sleepiness associated with:

• Narcolepsy
• Obstructive sleep apnea (OSA)
• Shift work disorder (SWD)

In patients with OSA, modafinil addresses excessive sleepiness but does not treat the underlying airway obstruction. Appropriate treatment of the underlying OSA, such as CPAP when prescribed, remains important.

Potential therapeutic benefits include:

• Promotes wakefulness
• Helps reduce excessive daytime sleepiness
• Supports alertness in patients with qualifying sleep disorders
• May improve daytime functioning when excessive sleepiness is adequately treated

Mechanism of Action

Modafinil promotes wakefulness through effects on several neurotransmitter systems in the brain. Its precise wakefulness-promoting mechanism is not completely understood, but modafinil increases dopaminergic signaling by inhibiting the dopamine transporter and has downstream effects involving other wakefulness-related neurotransmitter systems.

Unlike traditional stimulant medicines, modafinil has a distinct pharmacological profile, although it can still cause adverse effects and has recognized abuse and dependence considerations.

Dosage and Administration

The appropriate dose of modafinil should be determined by a qualified healthcare professional according to the patient’s diagnosis, response, other medicines, and medical history.

For approved adult indications, official labeling generally recommends:

• Narcolepsy/OSA: 200 mg once daily in the morning.
• Shift work disorder: 200 mg once daily, approximately one hour before the work shift.

Although doses up to 400 mg/day have been tolerated in studies, official labeling states that there is no consistent evidence that 400 mg provides additional benefit over 200 mg/day for narcolepsy or OSA. Therefore, Vilafinil 400 mg should not automatically be treated as a routine or starting dose.

Take the medicine exactly as prescribed. Do not increase the dose or frequency to obtain greater alertness.

Possible Side Effects

Common side effects associated with modafinil may include:

• Headache
• Nausea
• Nervousness or anxiety
• Insomnia
• Dizziness
• Dry mouth
• Diarrhea
• Reduced appetite

Serious reactions can occur. Modafinil labeling includes warnings concerning serious skin reactions, psychiatric symptoms, and hypersensitivity reactions. Stop the medicine and seek urgent medical attention if severe rash, blistering, facial swelling, breathing difficulty, hallucinations, or other serious symptoms occur.

Precautions and Warnings

Before using Vilafinil 400 mg, tell your healthcare professional if you have:

• Heart disease or high blood pressure
• A history of psychiatric illness
• Anxiety or mood disorders
• Liver or kidney problems
• A history of substance misuse
• Previous allergic reactions to modafinil or related medicines

Modafinil can affect sleep, blood pressure, heart rate, and mental health in susceptible individuals.

Because modafinil can interact with hormonal contraceptives and other medicines, provide your doctor with a complete list of prescription medicines, over-the-counter products, and supplements you use.
