Antiflu 75 Mg (Oseltamivir)

Introduction to Antiflu 75 mg (Oseltamivir)

Antiflu 75 mg is the brand name for Oseltamivir, an antiviral medication commonly used to treat and prevent influenza (flu). It is particularly effective against the influenza A and B viruses. Oseltamivir was developed by Hoffmann-La Roche, a global healthcare company, and is commonly used in both seasonal flu outbreaks and to reduce the severity of flu-related symptoms. It is widely prescribed to adults and children over the age of 1, as well as used in cases of suspected or confirmed exposure to the flu virus.

What is Antiflu 75 mg (Oseltamivir)?

Oseltamivir, the active ingredient in Antiflu 75 mg, is an oral neuraminidase inhibitor. Neuraminidase is an enzyme present on the surface of the influenza virus. This enzyme helps the virus to spread and infect other cells. By inhibiting neuraminidase, Oseltamivir prevents the influenza virus from multiplying and spreading throughout the body, thus helping to alleviate symptoms and shorten the duration of the illness.

Oseltamivir is classified as an antiviral rather than an antibiotic because it specifically targets viral infections. It is not effective against bacterial infections and should not be used to treat conditions such as the common cold or other respiratory infections that are caused by bacteria.

How Antiflu 75 mg (Oseltamivir) Works

Oseltamivir works by inhibiting the neuraminidase enzyme found on the surface of the influenza virus. Neuraminidase allows newly formed virus particles to be released from infected cells, which then infect other healthy cells. By blocking this enzyme, Oseltamivir prevents the virus from spreading to other parts of the body.

Specifically, Oseltamivir blocks the release of viral particles from infected cells, reducing viral replication and the severity of the infection. It works best when taken early in the infection (within the first 48 hours of symptoms), but can still provide benefit if started later, particularly in high-risk individuals.

Benefits of Antiflu 75 mg (Oseltamivir)

The primary benefits of Antiflu 75 mg (Oseltamivir) are related to its ability to:

1. Reduce the Duration of Flu Symptoms: When taken early, Oseltamivir can shorten the duration of flu symptoms (such as fever, chills, cough, sore throat, body aches, and fatigue) by about 1 to 2 days. This can help patients recover more quickly and return to daily activities sooner.
2. Prevent Flu Complications: For individuals at high risk of complications (such as the elderly, pregnant women, young children, and those with chronic medical conditions), Oseltamivir can help prevent complications such as pneumonia, which can result from a severe flu infection.
3. Reduce the Risk of Transmission: By reducing viral replication, Oseltamivir helps to lower the risk of spreading the virus to others, especially in close-contact environments like households or healthcare settings.
4. Prevention of Flu: Oseltamivir can be used prophylactically to prevent influenza in individuals who have been exposed to the virus. For example, if someone in a household has the flu, Oseltamivir can be taken to help prevent the person from developing the disease.

How to Take Antiflu 75 mg (Oseltamivir)

The dosage of Antiflu 75 mg depends on the purpose for which it is being prescribed and the age and health status of the patient.

• For Treatment of Influenza:
  • The standard dosage for adults and children over 13 years old is 75 mg twice daily for 5 days. It is most effective when started within 48 hours of the onset of symptoms.
  • For children between 1 and 12 years old, the dose is adjusted according to the child’s weight, and the duration of treatment remains the same.
• For Flu Prevention:
  • To prevent flu in individuals who have been exposed to the virus (e.g., household contact), 75 mg once daily for 10 days is typically recommended.
  • For long-term prevention (e.g., during an outbreak in a healthcare setting), a similar dose may be used for up to 6 weeks.

Oseltamivir is usually taken orally in the form of capsules or liquid suspension. It should be taken with food to reduce the likelihood of stomach upset. If a dose is missed, it should be taken as soon as possible unless it is nearly time for the next dose. Do not double the dose to make up for a missed dose.

Who Makes Antiflu 75 mg (Oseltamivir)?

Antiflu 75 mg is manufactured by Hoffmann-La Roche (commonly known as Roche), a global healthcare company headquartered in Switzerland. Roche is a well-established name in pharmaceuticals, particularly known for its work in oncology, infectious diseases, and immunology. Oseltamivir is one of the key antiviral medications produced by Roche for managing influenza infections.

In some countries, generic versions of Oseltamivir are available from other manufacturers once the patent for the drug expired.

Is Antiflu 75 mg (Oseltamivir) Safe for Humans?

Antiflu 75 mg (Oseltamivir) is considered safe for most humans when taken as prescribed, but as with all medications, it is important to follow the dosing instructions and consult a healthcare provider before use.

• Pregnancy and Breastfeeding: Oseltamivir is classified as a Category C drug by the FDA, which means that animal studies have shown some risk to the fetus, but there are no well-controlled studies in humans. It should only be used during pregnancy if the potential benefits justify the risks. Oseltamivir is excreted in breast milk, so caution is advised, but it is generally considered safe for breastfeeding women.
• Elderly Individuals: Older adults may be more susceptible to side effects, particularly if they have pre-existing medical conditions such as kidney disease.

Side Effects of Antiflu 75 mg (Oseltamivir)

While Antiflu 75 mg (Oseltamivir) is generally well tolerated, some people may experience side effects. Common side effects include:

• Gastrointestinal issues: Nausea, vomiting, abdominal pain, or diarrhea. These symptoms are generally mild and can be minimized by taking the medication with food.
• Headache: Some individuals report headaches while taking Oseltamivir.
• Fatigue or dizziness: These are less common but may occur.

In rare cases, more severe side effects can occur, including:

• Neuropsychiatric effects: There have been reports of abnormal behavior, confusion, or hallucinations, particularly in children and adolescents. If you or a loved one experiences any mental health changes, medical attention should be sought immediately.
• Severe allergic reactions: These can include swelling of the face or throat, difficulty breathing, or a rash.

If any severe side effects occur, seek medical help immediately.
