How to buy Tamiflu online?

Tamiflu can be taken as soon as you experience symptoms of influenza (flu) and is fast acting, meaning the severity is reduced within 48 hours and the duration of the condition is lessened by 30%. Available in a dosage of 75mg, Tamiflu can be purchased as a preventative if an influenza outbreak is about, or to treat the symptoms directly if you have the condition. Depending on the reason for you taking the prescription treatment, you can buy 10, 20, 30, 40 and 50 tablets at one time.

To order your ideal dosage of Tamiflu, you will need to complete a consultation. Traditionally finished in person, at OnlineClinic you can do this all online, especially if you are already bedbound with unpleasant symptoms. An outbreak of flu can hit you fast, so OnlineClinic offers a free next day delivery straight to your door.

What is Tamiflu?

Tamiflu is the branded medication of oseltamivir phosphate and is used to successfully treat influenza, more commonly known as flu. This medication is highly tolerable to all three strain of the virus – Types A, B and C – and can not only reduce the severity of the symptoms but decreases the timeframe as well. Tamiflu has been proven to be vastly effective at not only influenza outbreaks commonly associated with the winter months, but for strains and epidemics. Recent figures from the World Health Organisation (WHO) stated that Tamiflu was successful against 98% of samples for the swine flu pandemic in 2009.

Tamiflu can also be used for prevent an outbreak from spreading through a community or if someone closely connected to you has a strain of the virus, but not for seasonal flu that tends to occur every year. It is an antiviral medication in the form of tablets that can be purchased online with quantities of 10-50 at a time and can reduce the outbreak by 30%.

Short facts about Tamiflu
How to take

Tamiflu comes in tablet form and is typically taken over the course of 10 days. One Tamiflu is taken in the morning and one in the evening. Quantities can vary depending on the severity of your symptoms and you should always finish the full course.

How it works

Tamiflu targets the outbreak directly, not by eliminating the cells but by halting the spread so your body's immune system can combat the virus. Tamiflu can both reduce symptoms and lessen the length of the outbreak.


Tamiflu is highly effective, especially when started with 48 hours of experiencing symptoms. It can reduce the length of the outbreak by nearly a third (30%).


The only dosage available to buy at OnlineClinic is 75mg. You can order 10, 20, 30, 40 and 50 tablets at one time.

Side effects

Side effects when taking Tamiflu are rare but can include headaches, nausea/vomiting, diarrhoea and tiredness. For the full list of side effects, please read the patient leaflet at the right of the page.

How does Tamiflu work?

Tamiflu is a 75mg tablet containing the active ingredient oseltamivir phosphate that directly targets influenza. When taken within two days of experiencing symptoms of flu, Tamiflu will make any symptoms much more manageable and reduce the length of the outbreak by up to 30%.

To reduce any discomfort and relieve recovery, Tamiflu is an antiviral that targets the virus to halt the spread. This allows your body's immune system to attack the parts of the virus that are already present.

As well as helping the body defeat the outbreak, Tamiflu can significantly reduce the chance of you catching the virus by working as a prevention treatment when those around you have an epidemic or pandemic that is spreading. This is especially handy if you are in a health group susceptible to catching illnesses, such as asthmatics, the elderly or pregnant women.

How to take Tamiflu?

Tamiflu are tablets in 75mg dosage that are taken orally and quickly for maximum effectiveness (within 48 hours of experiencing symptoms). They can be taken by children, however when buying online, you must be 18 years or over and taking Tamiflu for your own personal use. Depending on your symptoms and how you're taking Tamiflu (for prevention or treatment) will depend on the quantity you're issued and how many to take daily. Below is the typical Tamiflu dosage and how to take, however always follow instructions issued by your doctor:

  • One tablet twice a day (one tablet in the morning and one in the evening)
  • Typical duration is over five days (10 capsules)
  • You can take with or without food (with food is preferred)

Taking Tamiflu during or after a meal is favourable with many people to help reduce any feelings of nausea. As with any course of antivirals or antibiotics, you should always finished the entire course you were prescribed, even if symptoms have cleared completely. This ensures a virus like influenza is completely out of your system and doesn't make another occurrence.


The only dosage of Tamiflu available from OnlineClinic is 75mg of oseltamivir phosphate and this is highly effective for adults in the UK. For children, the dosage is often lower. If you have taken the full course of Tamiflu (for a minimum of ten days depending on the course our doctor has recommended) and feel no different, you can order another dosage.

Side effects and precautions

Side effects of Tamiflu are unlikely and often manageable especially in comparison to the flu symptoms themselves. Some Tamiflu side effects include vomiting, diarrhoea, headaches, nausea, indigestion and abdominal pain. If any of these effects continue after the course of antivirals, or are particularly severe, contact your doctor with further information.

As well as side effects, there are some precautions to take into account before buying Tamiflu. These include if you are, have or have had:

  • Decreased kidney function
  • Any allergies to the ingredients
  • Pregnant or breastfeeding

Whilst Tamiflu is a preventive treatment, this is only for pandemic or epidemic in surrounding area, and shouldn't be used to prevent seasonal flu outbreaks, or as a substitute for the flu vaccination if you're liable for that particular treatment.
