Fluvir 75 mg Capsule

Fluvir 75 mg Capsule is a prescription antiviral medicine that contains 75 mg of oseltamivir in each capsule. It belongs to the neuraminidase inhibitor class and is used to treat influenza (the flu) caused by certain flu viruses, and in some cases to help prevent flu after exposure. Fluvir 75 mg Capsule is meant for oral use and is not a substitute for the flu vaccine.

How it works: Oseltamivir works by blocking a flu virus enzyme called neuraminidase, which helps newly made virus particles spread from infected cells. By limiting that spread, Fluvir 75 mg Capsule can help reduce how long flu symptoms last when started early.

Fluvir 75 mg Capsule is the standard adult-strength capsule form of oseltamivir, so it is commonly chosen when a full 75 mg dose is needed. Because this is a higher-strength capsule, it is typically used only after a clinician has assessed the patient; lower strengths or liquid forms may be preferred for children, people who need dose adjustments, or those who cannot swallow capsules.

• Treatment of influenza A and influenza B
• Prevention of flu after close exposure
• Post-exposure flu prophylaxis in selected patients
• Seasonal flu prevention when prescribed by a doctor

• Swallow Fluvir 75 mg Capsule whole with water; do not crush, chew, or open it unless your prescriber tells you to.
• It can be taken with or without food, but taking it with food may help lessen nausea.
• Start it as soon as possible after flu symptoms begin, because it works best when started early.
• If it is prescribed for prevention, take it exactly on the schedule your doctor gives you, even if you feel well.
• Do not share Fluvir 75 mg Capsule with anyone else, even if they have flu-like symptoms.

Each Fluvir 75 mg Capsule provides 75 mg of oseltamivir per capsule. Depending on why it is prescribed, a doctor may have you take it once or twice daily; the exact schedule and duration depend on your age, kidney function, and whether it is being used for treatment or prevention. Do not take more than prescribed, and the maximum daily amount is determined by the prescriber for your situation.

Do not change your dose or stop the medicine without speaking to your doctor.

Common side effects of Oseltamivir may include:

• Fluvir 75 mg Capsule is a higher-strength adult capsule and may not be suitable for children or anyone who needs a dose adjustment without medical guidance.
• Tell your doctor if you have kidney disease, since oseltamivir dosing may need to be changed.
• Use caution if you have a history of severe drug allergies or skin reactions.
• If you have persistent vomiting, dehydration, or cannot keep capsules down, contact your clinician.
• This medicine may not immediately make you feel better, and flu symptoms can still worsen or complications can still occur.
• Contact a doctor promptly if you have shortness of breath, chest pain, or signs of a more serious infection.
• Tell your clinician about pregnancy or breastfeeding before taking Fluvir 75 mg Capsule.

• Live attenuated influenza vaccine given by the nose may be less effective if used around the time of oseltamivir therapy.
• Probenecid may increase oseltamivir levels in the body.
• Other medicines that affect the kidneys may matter if you have reduced kidney function.
• Always tell your doctor about prescription drugs, over-the-counter medicines, and supplements before starting Fluvir 75 mg Capsule.
