VILAFINIL 400

What is VILAFINIL 400?

VILAFINIL 400 is an oral tablet medication containing a high dose of 400 mg of modafinil. It belongs to the class of agents that promote wakefulness and affect the central nervous system. The drug is used in adult patients for medical indications associated with excessive daytime sleepiness. The manufacturer of VILAFINIL 400 is Fortune Healthcare, a pharmaceutical company known for producing generic medicines.

Modafinil is not a classic psychostimulant in the traditional sense, although it has an activating effect on the nervous system. Its action is related to the regulation of neurotransmitters — substances through which nerve cells transmit signals to one another. Due to this, excessive daytime sleepiness can be reduced, and the ability to maintain attention and perform daily tasks can be improved. At the same time, VILAFINIL 400 does not replace full sleep and does not eliminate the cause of sleep disorders without proper medical evaluation.

The high dosage requires a particularly responsible approach to use and prior consultation with a physician. Self-medication for fatigue, work overload, or lack of sleep can be dangerous, as it can mask the symptoms of underlying diseases. The doctor evaluates the causes of sleepiness, concomitant diseases, risks of interaction, and the appropriateness of therapy. It is important to consider that the response to VILAFINIL 400 is individual and depends on the state of the nervous system, age, other medications taken, and other factors.

What is VILAFINIL 400 prescribed for?

The primary indication for modafinil is the treatment of excessive daytime sleepiness, where a person experiences a strong urge to fall asleep during the day despite an adequate duration of night rest. This condition can accompany narcolepsy — a neurological disorder characterized by uncontrollable episodes of falling asleep. The medication helps maintain alertness during periods when the patient needs to remain active. However, it is not a cure for all manifestations of narcolepsy and does not replace comprehensive therapy.

VILAFINIL 400 may also be prescribed for sleepiness associated with obstructive sleep apnea. In this condition, repeated brief pauses or significant limitations in breathing occur during sleep, which worsens blood oxygen saturation and disrupts sleep structure. Modafinil does not eliminate airway obstruction, so it cannot replace primary treatment, including the use of special breathing support devices. It is considered only as an adjunctive agent if sleepiness persists despite adequate basic therapy.

Another possible indication is shift work sleep disorder, where night shifts or unstable schedules disrupt natural circadian rhythms. In such cases, the drug can help reduce sleepiness during the work shift, but it does not eliminate the need for organized rest periods. The prescription, dose, and timing of administration must be determined individually by a doctor. Using VILAFINIL 400 to increase productivity in healthy individuals is not a safe or recommended medical practice.

Composition and active components of VILAFINIL 400

The main active substance of VILAFINIL 400 is modafinil at a dose of 400 mg in one tablet. Modafinil affects neurotransmitter systems, particularly dopamine, norepinephrine, histamine, and orexin mechanisms of wakefulness regulation. In simple terms, it helps the brain better maintain a state of activity and counteract pathological sleepiness. The exact mechanism of action is multi-component, so the drug should not be compared to ordinary tonic agents or caffeinated beverages.

The tablet also contains auxiliary components necessary for formulation, stability of the drug, and proper release of the active substance. Their specific list may vary depending on the production batch, so it should be verified in the official instructions or on the packaging. Patients with allergies, lactose intolerance, or other specific conditions should inform their doctor or pharmacist. If signs of an allergic reaction appear, tablet intake must be stopped, and medical assistance should be sought.

Dosage of VILAFINIL 400

The dosage of modafinil is determined by a doctor after evaluating the diagnosis, severity of sleepiness, concomitant diseases, and drug interactions. In clinical practice, daily doses for adults often range from 200–400 mg; however, VILAFINIL 400 contains the maximum common daily amount of the active substance. Not every patient requires a dose of 400 mg, and increasing the dose does not always yield a better therapeutic result. You should not independently divide, double, or change the dosing regimen without a specialist's recommendation.

For narcolepsy or residual sleepiness associated with sleep apnea, the daily dose is usually taken in the morning to reduce the risk of insomnia in the evening. In some regimens, the doctor may divide the daily amount into a morning and midday dose. For shift work sleep disorder, the timing of use is selected relative to the start of the shift. The duration of treatment depends on the cause of sleepiness and requires periodic evaluation of efficacy and tolerability.

Elderly patients, individuals with impaired liver function, cardiovascular diseases, or psychiatric disorders may require a lower starting dose and closer medical supervision. In cases of severe liver impairment, the dose of modafinil is typically reduced. In renal failure, the decision is made individually, taking into account the general condition. Before starting treatment with VILAFINIL 400, consultation with a doctor is mandatory, especially if the patient is already taking other medications.

How to take VILAFINIL 400 correctly?

The VILAFINIL 400 tablet is swallowed whole with a sufficient amount of water. The drug can be taken with or without food, although fatty food can sometimes slightly delay the onset of action. To reduce the risk of sleep disturbance at night, it is not recommended to use modafinil in the afternoon or evening unless otherwise prescribed by a doctor. It is important to adhere to the same administration time in accordance with the individual treatment plan.

If a dose is missed, a double amount of tablets should not be taken to compensate. If there is little time left before night sleep, it is better to discuss the missed dose with a doctor or pharmacist, as late administration can cause insomnia. Do not exceed the prescribed daily dose even if the effect seems insufficient. Increased sleepiness, unusual fatigue, or decreased concentration may be signs of a need to adjust the primary treatment, rather than a reason to independently increase the dose.

During therapy, it is advisable to maintain a regular sleep schedule, avoid chronic sleep deprivation, and monitor blood pressure if there is a tendency for it to rise. VILAFINIL 400 does not guarantee complete restoration of the ability to safely drive or operate machinery. Until your personal response to the drug is evaluated, you should avoid potentially dangerous activities. The individual reaction of the body may include both a pronounced improvement in alertness and undesirable neuropsychiatric or cardiovascular symptoms.

Side effects of VILAFINIL 400

Most commonly, modafinil can cause headache, nausea, dry mouth, decreased appetite, nervousness, or insomnia. Some patients report dizziness, tremors, rapid heartbeat, abdominal pain, or increased anxiety. Such reactions may be more noticeable at the beginning of treatment or when using high doses. If symptoms do not resolve, worsen, or significantly affect well-being, a medical consultation is necessary.

Less frequently, changes in mood, irritability, depressive symptoms, agitation, confusion, or the appearance of unusual thoughts and behavior may occur. Special caution is required for patients with a history of psychiatric disorders, as the stimulating effect on the central nervous system can exacerbate certain symptoms. Fluctuations in blood pressure and heart rate are also possible. In case of chest pain, severe palpitations, fainting, or shortness of breath, immediate medical attention should be sought.

Severe skin and allergic reactions, although rare, are dangerous: blistering rash, mucosal lesions, facial swelling, difficulty breathing, fever, or swollen lymph nodes. If any widespread rash appears, especially accompanied by fever or sore throat, VILAFINIL 400 must be discontinued, and a doctor should be contacted urgently. Do not resume use after a suspected serious reaction without a medical decision. Early recognition of such symptoms is crucial for patient safety.

Contraindications of VILAFINIL 400

VILAFINIL 400 is contraindicated in case of hypersensitivity to modafinil or any auxiliary component of the tablet. The drug should not be used if allergic reactions to modafinil have occurred in the past, especially if they were accompanied by rash, swelling, or mucosal lesions. Caution is required in uncontrolled arterial hypertension, arrhythmias, ischemic heart disease, and other significant cardiovascular pathologies. Before prescribing, the doctor may recommend an assessment of blood pressure, heart rate, and cardiological history.

Relative contraindications include anxiety disorders, depression, psychosis, bipolar disorder, susceptibility to addiction, severe liver disease, and severe renal impairment. Modafinil can affect the mental state, so if aggressiveness, manic symptoms, hallucinations, or suicidal thoughts appear, an urgent medical evaluation is required. Patients with such conditions should take the drug only under the supervision of a specialist. It is important to inform the doctor about all past illnesses and prior adverse drug reactions.

The use of VILAFINIL 400 during pregnancy and lactation is not recommended without clear medical justification, as safety for the fetus and infant requires a separate assessment. Women of childbearing potential should discuss reliable methods of contraception with their doctor, as modafinil can reduce the effectiveness of certain hormonal contraceptives. The drug is generally not used in children and adolescents due to insufficient safety data and the risk of severe skin reactions. In the elderly, therapy is initiated with particular caution due to possible concomitant diseases and polypharmacy.

Interaction of VILAFINIL 400 with other medicines and alcohol

Modafinil can alter the activity of liver enzymes involved in the metabolism of many drugs. Because of this, it can weaken the effect of some hormonal contraceptives and affect the concentration of certain anticoagulants, anticonvulsants, sedatives, antidepressants, and other agents. Special attention is paid to co-administration with drugs that affect heart rhythm, blood pressure, or mental state. A complete list of medications, including over-the-counter drugs, herbal supplements, and vitamins, must be reported to the doctor before starting VILAFINIL 400.

Alcohol is undesirable during treatment, as it can unpredictably affect the nervous system, sleep, attention, and tolerability of the drug. Combining alcohol with modafinil can mask the degree of intoxication, increase the risk of impulsive behavior, anxiety, or impaired coordination. Even if you feel alert, you should not consider yourself fully capable of safe driving. Until an individual response to the drug is established, you should refrain from driving, working at heights, and operating complex machinery.
