What is Tamiflu?
Tamiflu is the brand name for a medication called oseltamivir phosphate. It’s an antiviral medication that’s used to treat and prevent the flu. Tamiflu works by blocking the action of an enzyme that the flu virus needs to replicate itself. This means that the virus can’t spread as easily in your body, which can help to reduce the severity and length of your flu symptoms
Tamiflu is available in a few different forms, including capsules, a liquid suspension, and even a powder that can be mixed with water. It’s usually taken orally, and it’s most effective when taken within the first 48 hours of experiencing flu symptoms.
Tamiflu is not a cure for influenza, but it can reduce the severity of symptoms and help you feel better more quickly.
Tamiflu may help you:
- Reduce your risk of getting sick if you get sick with flu
- Reduce your risk of hospitalization if you have flu-like symptoms but aren’t seriously ill yet
- Help your body fight off any lingering flu symptoms once you’re better
What does Tamiflu do?
Tamiflu is a medicine that helps reduce your symptoms of flu by blocking the action of your body’s natural defense system from fighting off the virus. When you take Tamiflu every day for 7 days, it will help protect you against getting sick and reducing the duration and severity of symptoms.
Why do people take it?
There are a few different reasons why someone might take Tamiflu. The most common reason is to treat the flu. If you’ve already come down with the flu, taking Tamiflu can help to reduce the severity and length of your symptoms. Tamiflu can also help to prevent complications from the flu, such as pneumonia.
Another reason why someone might take Tamiflu is to prevent the flu. If you’ve been exposed to someone who has the flu, and you’re at risk of getting sick (for example, if you have a weakened immune system), taking Tamiflu can help to prevent you from getting the flu in the first place.
It’s important to note that Tamiflu isn’t a cure for the flu. It won’t make your symptoms go away instantly, and it won’t completely prevent you from getting sick.
However, it can help to make your symptoms more manageable, and it can help to prevent complications from the flu.
The typical dosage of Tamiflu depends on several factors, such as age, weight, severity of symptoms, and overall health. In general, adults and children over 12 years old should take 75mg of Tamiflu twice a day for 5 days. Children under 12 years old should take a lower dose based on their weight. For example, children weighing less than 40kg should take 30-60mg of Tamiflu twice a day for 5 days.
It is important to note that the dosage of Tamiflu may vary if you have kidney or liver problems. In such cases, your doctor may adjust the dosage or recommend a different medication.
Additionally, you should always take Tamiflu as prescribed by your doctor and finish the entire course of treatment, even if you start feeling better before the end of 5 days.
Take your Tamiflu medication as soon as you remember if you miss one. If your next dose is approaching, skip the missed one and carry on with your regular plan. Do not double up on your medication to make up for a missing dosage.
Tamiflu Side Effects
Like any medication, Tamiflu may cause side effects in some people it include:
- stomach pain
However, if you experience any severe or unusual side effects, such as difficulty breathing, chest pain, or severe skin rash, seek medical attention immediately.
It is also important to note that Tamiflu may interact with other medications or health conditions. Therefore, you should inform your doctor of any medications, supplements, or health conditions you have before taking Tamiflu.
Tamiflu Interaction with Other Drugs
Tamiflu may interact with several drugs, such as:
- Probenecid (used to treat gout or kidney problems)
- Warfarin (used to thin the blood)
- Theophylline (used to treat asthma or COPD)
- Oral contraceptives
These drugs may either decrease or increase the effects of Tamiflu or cause additional side effects. Therefore, your doctor may need to adjust the dosage of Tamiflu or recommend a different medication.
In addition, Tamiflu should not be taken with live attenuated influenza vaccine (LAIV), which is a nasal spray flu vaccine. If you have received LAIV, you should wait at least 2 weeks before taking Tamiflu.
