Frequently asked questions

Fluvir 75mg Capsule is an antiviral medicine used to treat and prevent influenza (flu) caused by influenza A and B viruses. It may be prescribed for adults and children, depending on age, body weight, and the condition being treated. The medicine works by stopping the virus from spreading inside the body, which helps reduce symptoms and speed recovery. It should be taken only as prescribed by a doctor.
No, Fluvir 75mg Capsule does not treat the common cold. It is an antiviral medicine used specifically for influenza (flu), not for common cold infections. Although flu and cold symptoms may look similar (like runny nose, cough, or sore throat), they are caused by different viruses, and this medicine works only against the influenza virus.
No, Fluvir 75mg Capsule is not an antibiotic. It is an antiviral medicine (oseltamivir). Antibiotics work against bacteria, whereas Fluvir 75mg Capsule works by stopping the spread of the flu virus in the body. So, it will not treat bacterial infections and should only be used when prescribed for flu by your doctor.
Fluvir 75mg Capsule should be started as soon as possible after flu symptoms begin, ideally within 48 hours for the best results. Early treatment helps the medicine work more effectively by slowing the spread of the influenza virus in the body. It may also be prescribed within 48 hours after close contact with someone who has the flu to help prevent infection. Always use it exactly as directed by your doctor.
Yes, Fluvir 75mg Capsule may be used to prevent influenza after close contact with someone who has the infection if prescribed by a doctor. It helps stop the influenza virus from multiplying in the body and may reduce the chance of developing flu symptoms. However, it is not meant for routine cough or the common cold. For prevention, it should usually be started within 48 hours of exposure and taken exactly as advised by your doctor.
Fluvir 75mg Capsule should be given to children only if a doctor has recommended it for that specific child. The safety and dose depend on the child’s age, body weight, hydration status, fever pattern, and the exact illness being treated. Children respond differently to medicines, so proper medical guidance is important. Seek medical help quickly if the child becomes unusually sleepy, breathless, unable to drink fluids, or develops a rash after taking Fluvir 75mg Capsule syrup.
Fluvir 75mg Capsule does not usually cause sleepiness in most people, but individual reactions can vary depending on the medicine and the person’s health condition. Some people may experience mild dizziness or tiredness while their body adjusts to treatment. If you feel unusually sleepy, dizzy, or unwell after taking the medicine, avoid driving or operating machinery and consult your doctor.
No, Fluvir 75mg Capsule is not a steroid. It is an antiviral medicine designed to stop influenza viruses from multiplying in the body. Steroids work differently by reducing inflammation, while antiviral medicines specifically target viruses. Always use Fluvir 75mg Capsule syrup only for the condition prescribed by your doctor and not for general cold or cough symptoms.
If you miss a dose of Fluvir 75mg Capsule, take it as soon as you remember, unless it is almost time for your next scheduled dose. In that case, skip the missed dose and continue with your normal schedule. Do not take a double dose to make up for a missed one because it may increase side effects without improving effectiveness. If you frequently miss doses, consult your doctor for advice.
Fluvir 75mg Capsule can usually be taken with or without food as directed by your doctor. Taking it with food may help reduce stomach discomfort in some people. If vomiting or stomach upset occurs, your doctor may recommend taking it after meals and maintaining good hydration. Always follow the instructions given by your doctor.
Some people may experience mild side effects such as nausea, vomiting, stomach upset, dizziness, or loose stools while taking Fluvir 75mg Capsule. These effects are usually temporary and improve as the body adjusts to the medicine. However, seek medical attention immediately if you notice severe rash, breathing difficulty, swelling of the face, fainting, or other unusual symptoms.
Fluvir 75mg Capsule should only be used during pregnancy if a doctor clearly recommends it. The safety of medicines during pregnancy depends on the stage of pregnancy and the reason for treatment. Because some medicines may affect the baby, it is important to consult a doctor before starting, stopping, or repeating Fluvir 75mg Capsule syrup during pregnancy.
Fluvir 75mg Capsule may be unsafe to use during breastfeeding. Limited data suggest that the medicine can pass into breast milk and may harm the baby. It should be used only if your doctor decides that the benefit to you outweighs the possible risk to your baby. Always consult your doctor before using this medicine while breastfeeding. If prescribed, monitor your baby for any unusual symptoms such as excessive sleepiness, poor feeding, or rash, and seek medical advice if these occur.
Fluvir 75mg Capsule should be used with caution in people who have kidney disease and only under a doctor’s supervision. Kidney problems can affect how medicines are processed in the body and may increase the risk of side effects. If you notice reduced urine output, swelling, or unusual weakness while taking Fluvir 75mg Capsule syrup, consult your doctor promptly.
Fluvir 75mg Capsule is generally safe to use in patients with liver disease, and no dose adjustment is usually required. However, it is still advisable to use this medicine under medical guidance, especially if you have an existing liver condition. If you notice symptoms such as yellowing of the eyes or skin, dark urine, severe nausea, or unusual tiredness, contact your doctor promptly.
