Question 1

What is Tamiflu?

Accepted Answer

Tamiflu is a prescription antiviral medicine that belongs to a group of drugs known as neuraminidase inhibitors. It works by blocking the action of an enzyme that the influenza virus needs to spread and infect other cells in the body.

This medication is designed to target both influenza A and B viruses. By interfering with the viral replication process, it helps manage the spread of the virus within the respiratory system.

Question 2

What is Tamiflu used for?

Accepted Answer

Tamiflu is used to treat:

Prophylaxis of influenza

Treatment of influenza

Question 3

How does Tamiflu work?

Accepted Answer

Mechanism of Action

Tamiflu belongs to a class of drugs known as neuraminidase inhibitors. It targets a specific enzyme called neuraminidase, which is found on the surface of the influenza virus. This enzyme acts like a key that allows newly formed virus particles to break out of an infected cell and move on to infect neighboring healthy cells.

By blocking this enzyme, Tamiflu effectively traps the virus inside the already infected cells. This prevents the infection from spreading further within the respiratory system, which can help shorten the duration of the illness and reduce the severity of symptoms.

Effectiveness and Timing

Tamiflu is active against both Influenza A and Influenza B viruses. Because the medication works by stopping the spread of the virus rather than killing it directly, it is most effective when taken as soon as possible after symptoms appear. Clinical evidence suggests that the treatment is most beneficial when started within 48 hours of the first signs of the flu.

Question 7

What is the dosage of Tamiflu and how do I take it?

Accepted Answer

How to Take Tamiflu

Tamiflu is an oral medication available in capsule form or as a liquid suspension. For treating flu symptoms, it is typically taken twice daily. For preventing the flu after exposure, it is usually taken once daily. To be most effective, treatment should begin shortly after the start of symptoms or exposure.

You may take Tamiflu with or without food. If the medication causes stomach upset, taking it with food or milk may help.

Administration Instructions

Liquid form: Shake the oral suspension well before each use. Use the specific measuring device provided with the medication to ensure the correct amount is taken. Do not use a household spoon.

Capsule form: If you have difficulty swallowing capsules, your healthcare provider may provide instructions on how to open the capsule and mix the contents with a sweetened liquid, such as chocolate syrup, for immediate use.

Completion: It is important to complete the entire course of treatment as directed, even if you begin to feel better before the medication is finished.

Missed Dose

If you miss a dose, take it as soon as you remember. If it is nearly time for your next scheduled dose, skip the missed dose and continue with your regular timing. Do not take two doses at once to make up for a missed one.

Question 8

Is Tamiflu safe during pregnancy and breastfeeding?

Accepted Answer

Pregnancy

Pregnant individuals are at a higher risk for severe complications from the flu. While data from studies have not shown an increased risk of birth defects or other pregnancy complications associated with Tamiflu, it is typically reserved for cases where the benefit to the mother justifies the potential risk to the fetus.

Breastfeeding

Tamiflu and its active components are known to pass into breast milk in very small amounts. These levels are unlikely to cause adverse effects in a nursing infant. Decisions regarding breastfeeding while taking this medication should be made in consultation with a healthcare professional.

Important Considerations

If you are pregnant or nursing, talk to your healthcare provider about:

The risks of untreated influenza compared to the risks of the medication.

The timing of your symptoms and when to start treatment.

Any concerns regarding the health of your baby.

Question 9

What forms and strengths does Tamiflu come in?

Accepted Answer

Tamiflu is manufactured in oral formulations for the treatment and prevention of influenza. The available forms include:

What is the FDA approval status of Tamiflu?

Accepted Answer

FDA Approval and Generic Availability

Tamiflu (oseltamivir phosphate) was originally approved by the U.S. Food and Drug Administration (FDA) in 1999. In 2016, the FDA approved the first generic version of the medication, which increased the availability of oseltamivir in capsule and oral suspension forms.

Approved Indications

The FDA has authorized Tamiflu for the following specific uses:

Treatment: For patients 2 weeks of age and older who have experienced flu symptoms for no more than 48 hours.

Prevention: For patients 1 year of age and older to prevent the flu after exposure to an infected individual or during a community outbreak.

Regulatory Safety Monitoring

The FDA has issued safety communications regarding neuropsychiatric events associated with Tamiflu use, particularly in children and adolescents. These events may include symptoms such as delirium, hallucinations, confusion, and self-injury. While it is not certain if these behaviors are caused by the medication or the influenza virus itself, the FDA requires that the product labeling include information about these potential risks. Caregivers and patients are advised to monitor for any signs of unusual behavior and contact a healthcare provider if they occur.
