FERAVIR 200 MG

Description

Feravir 200 mg Tablet is a potent antiviral medication designed to combat RNA virus infections. Its active ingredient, favipiravir, has garnered significant attention in recent years due to its efficacy against viral illnesses such as COVID-19 and influenza. This medication plays a vital role in reducing the severity and duration of viral infections by targeting and inhibiting the replication machinery of viruses. Available in an oral tablet form, Feravir offers patients an accessible and effective option to manage viral diseases under medical supervision.

Composition and Formulation

Each tablet of Feravir contains 200 mg of favipiravir as the active component. Favipiravir belongs to a class of antiviral agents known as pyrazinecarboxamide derivatives. The tablet also includes various inactive ingredients or excipients that ensure the stability, effectiveness, and ease of administration of the medicine. These excipients aid in the tablet’s manufacturing, consistency, and absorption within the gastrointestinal tract.

Pharmacological Action

Favipiravir acts by selectively inhibiting RNA-dependent RNA polymerase, an enzyme essential for viral replication. Since many viruses, including influenza and coronaviruses, depend on this enzyme to reproduce their genetic material and proliferate inside host cells, blocking its activity prevents the virus from multiplying. This interruption in viral replication decreases viral load, limits tissue damage, and allows the immune system to control the infection more efficiently.

This antiviral mechanism is particularly valuable during the early stages of infection, helping to mitigate symptoms and reduce the chance of severe disease progression. Moreover, favipiravir’s broad-spectrum activity allows it to be effective against a variety of RNA viruses.

Indications

Feravir 200 mg Tablet is primarily indicated for:

• Treatment of COVID-19: Especially in mild to moderate cases, it helps reduce viral load and alleviate symptoms.

• Management of Influenza: Favipiravir is effective against various strains of influenza viruses, reducing symptom severity and duration.

• Other RNA Viral Infections: As prescribed by a qualified healthcare professional, especially when caused by viruses susceptible to favipiravir.

It is important that Feravir be used only under medical advice, particularly because viral infections can vary in severity and may require tailored therapeutic approaches.

Dosage and Administration

The dosage of Feravir 200 mg Tablet depends on the specific viral infection being treated and the patient’s health status. Typical dosage guidelines for COVID-19 are:

• Day 1: An initial loading dose of 1600 mg, administered as 200 mg tablets taken four times throughout the day.

• Days 2 to 5: A maintenance dose of 600 mg daily, given as 200 mg tablets three times a day.

For other viral infections such as influenza, dosing may vary based on the prescribing doctor’s instructions.

Feravir tablets should be taken orally, with or without food. Swallow tablets whole with water and avoid crushing or chewing to ensure proper absorption.

Advantages of Feravir

• Broad-Spectrum Antiviral: Active against a wide range of RNA viruses, making it versatile for treating various viral infections.

• Oral Administration: Easy to take, which improves patient compliance compared to injectable antivirals.

• Early Intervention: When administered promptly, it can reduce the severity and duration of viral illnesses.

• Well-Tolerated: Generally causes mild side effects, especially when taken as prescribed.

Contraindications

Feravir 200 mg should not be taken by individuals who:

• Have a known hypersensitivity or allergy to favipiravir or any tablet components.

• Are pregnant or planning to become pregnant, due to potential risks to the fetus.

• Are breastfeeding, as the drug may pass into breast milk.

• Have severe liver or kidney impairments, where drug metabolism and clearance might be compromised.

• Have a history of gout or elevated uric acid levels without proper monitoring.

Precautions and Safety Measures

Before starting treatment with Feravir, patients must disclose their full medical history to the healthcare provider. Particular caution is advised in:

• Pregnant and Lactating Women: Use is contraindicated because of potential teratogenic effects and lack of safety data.

• Patients with Liver or Kidney Conditions: Dose adjustments or alternative treatments may be necessary due to altered drug clearance.

• Individuals with Gout or Hyperuricemia: Favipiravir can increase uric acid levels, which may exacerbate these conditions.

• Elderly Patients: They may be more susceptible to side effects and require closer monitoring.

Possible Side Effects

While Feravir is generally safe when used as prescribed, some patients may experience side effects including:

• Common: Nausea, vomiting, diarrhea, mild headaches, and transient elevations in uric acid.

• Uncommon: Elevated liver enzymes indicating mild liver irritation.

• Rare but Serious: Severe allergic reactions, liver toxicity, or heart rhythm disturbances.

Any unusual symptoms, especially severe gastrointestinal discomfort, jaundice, or allergic reactions, should prompt immediate medical consultation.

Drug Interactions

Favipiravir may interact with other medications, so patients should inform their healthcare provider about all medicines, supplements, or herbal products they are taking. Interactions may occur with:

• Other antiviral agents.

• Drugs that influence liver enzymes involved in favipiravir metabolism.

• Medications that affect uric acid levels.

Close monitoring or dose modifications may be necessary to avoid adverse effects or reduced efficacy.

Overdose and Management

In case of suspected overdose, patients should seek emergency medical attention immediately. Symptoms of overdose may include severe nausea, vomiting, abdominal pain, or neurological symptoms. There is no specific antidote for favipiravir overdose; treatment is supportive and symptomatic.

Storage Instructions

• Store Feravir tablets in a cool, dry place away from direct sunlight.

• Maintain storage temperature between 15°C and 30°C.

• Keep out of reach of children and pets.

• Do not use tablets beyond the expiry date printed on the packaging.

Patient Counseling and Compliance

For optimal results, patients should be educated on the importance of:

• Completing the full course of therapy even if symptoms improve early.

• Avoiding self-medication or dose alteration.

• Reporting side effects or unusual symptoms promptly.

• Adhering to prescribed dosages and timings.

• Avoiding alcohol or substances that may strain liver function during treatment.

Clinical Significance and Role in Treatment

Feravir 200 mg Tablet holds an important place in managing viral infections due to its mechanism targeting viral replication. Early intervention with favipiravir can reduce viral shedding, lessen disease severity, and potentially lower transmission risk.

In pandemic scenarios, medications like Feravir help reduce healthcare burdens by shortening hospital stays and improving recovery times. Its oral route and relatively safe profile make it suitable for outpatient treatment in appropriate cases.
