Tamiflu, also known by its generic name oseltamivir, is an antiviral medication that is used to treat and prevent influenza (flu) infections caused by the influenza A and B viruses.
Dosage:
The recommended dosage of Tamiflu for the treatment of influenza in adults and adolescents 13 years of age and older is as follows:
- Treatment of Influenza: The typical dosage is 75mg (one 75mg capsule) taken orally twice a day, with each dose given approximately 12 hours apart, for a total duration of 5 days.
- Prophylaxis of Influenza: The usual dosage for preventing influenza after close contact with an infected individual is 75mg (one 75mg capsule) taken orally once daily for a duration of 10 days.
For children between the ages of 1 and 12 years, the dosage is based on body weight. The healthcare provider will determine the appropriate dose for children based on their weight and age.
Usage:
Tamiflu is most effective when it is started within 48 hours of the onset of flu symptoms. It is important to follow the instructions provided by the healthcare provider or the instructions on the prescription label.
The capsules should be swallowed whole with water, with or without food. If an individual has difficulty swallowing the capsule, it can be opened and mixed with a small amount of sweetened liquid, such as regular or sugar-free chocolate syrup, in a container. This mixture should be consumed immediately after preparation.
It is important to complete the full course of treatment as prescribed, even if symptoms improve before the medication is finished. This will help ensure that the infection is fully treated and reduce the risk of developing antiviral resistance.
Tamiflu may cause side effects such as nausea, vomiting, headache, and diarrhea. If these side effects persist or worsen, it is advisable to contact a healthcare professional.
It is worth noting that Tamiflu is not a substitute for receiving an annual flu vaccine. Vaccination is the most effective way to prevent the flu and is recommended for everyone 6 months of age and older, unless contraindicated.
In summary, Tamiflu is an antiviral medication used to treat and prevent influenza. Following the prescribed dosage and usage instructions, and starting the medication early after flu symptoms appear, can help reduce the duration and severity of the illness. It is important to consult with a healthcare provider for personalized advice regarding the use of Tamiflu.
