Frequently Asked Questions for Tamiflu

What is Tamiflu?

Tamiflu is often used during flu outbreaks to help reduce the severity of symptoms and shorten the duration of illness. It is also sometimes used as a preventative measure to help reduce the risk of getting the flu, especially for people who are at high risk of developing serious complications from the illness. Tamiflu is typically taken orally in capsule or liquid form. It is important to note that Tamiflu is most effective when it is started within 48 hours of the onset of flu symptoms.


Can buy Tamiflu online?

Tamiflu is a prescription medication, which means that you need a prescription to buy it. In some cases, it may be possible to obtain a prescription for Tamiflu through an online consultation with a licensed healthcare provider. However, it is important to use caution when purchasing medications online, as there are many illegitimate websites that sell counterfeit or expired drugs. It is always recommended to purchase medications from a reputable online pharmacy that is licensed and verified by a regulatory agency.

Additionally, it is important to follow the instructions of your healthcare provider when taking Tamiflu, and to never take it without a prescription or use it for purposes other than those prescribed by your doctor.

How do I take Tamiflu?

Tamiflu (oseltamivir) is usually taken orally in the form of capsules or a liquid suspension. The dosage and duration of treatment will depend on your age, weight, the severity of your symptoms, and other medical conditions you may have. It's important to follow your doctor's instructions carefully when taking Tamiflu.

In general, Tamiflu is usually taken twice a day for five days, although your doctor may adjust the dosage or duration of treatment based on your specific circumstances.

Here are some general guidelines on how to take Tamiflu:

  1. Take Tamiflu as soon as possible after the onset of flu symptoms, ideally within 48 hours.

  2. Take Tamiflu with a full glass of water, with or without food.

  3. If you are taking Tamiflu in capsule form, swallow the capsule whole. Do not crush, chew, or break the capsule.

  4. If you are taking Tamiflu in liquid form, use the dosing syringe or measuring spoon provided to measure the correct dose. Shake the suspension well before use.

  5. Finish the entire course of Tamiflu, even if you start feeling better before the end of the treatment.

  6. If you miss a dose of Tamiflu, take it as soon as you remember. If it's almost time for your next dose, skip the missed dose and continue with your regular dosing schedule.

If you have any questions about how to take Tamiflu, be sure to ask your doctor or pharmacist for guidance.

Can I take Tamiflu with my other medication?

Tamiflu (oseltamivir) may interact with other medications, so it is important to inform your healthcare provider of all the medications you are taking, including prescription drugs, over-the-counter medicines, and herbal supplements. Some medications that may interact with Tamiflu include:

  1. Probenecid: This medication may increase the level of Tamiflu in your blood, which can increase the risk of side effects.

  2. Chlorpropamide: This medication may decrease the level of Tamiflu in your blood, which can reduce its effectiveness.

  3. Warfarin: Tamiflu may increase the anticoagulant effect of warfarin, which can increase the risk of bleeding.

  4. Vaccines: Tamiflu may reduce the effectiveness of some vaccines, so it's important to consult with your doctor before receiving any vaccines while taking Tamiflu.

  5. Other antiviral medications: Tamiflu may interact with other antiviral medications, so it's important to inform your doctor if you are taking any other antiviral drugs.

Your doctor will be able to advise you on whether it is safe to take Tamiflu with your other medications, and may adjust your dose or prescribe an alternative medication if necessary. It's important to always follow your doctor's instructions and to inform them of any changes in your medication regimen.
