More commonly known as "the flu", influenza is a highly infectious disease characterised by the sudden onset of high fever, aching muscles, headaches, a cough, sore throat and rhinitis. Whilst for most, your body can fight off the infection; it can be a serious concern for the very young, the elderly and those with underlying health conditions such as asthma. If you have contracted flu, you get an effective prescription medication Tamiflu, which prevents and reduces the duration of illness, and reduces the severity of symptoms and infections. You can buy Tamiflu online here at HealthExpress after you have completed our free consultation reviewed by our UK registered doctors. We offer free next day delivery, and even same day delivery for London postcodes.

What is influenza?

Commonly known as flu, influenza is an illness caused by RNA viruses that infect the respiratory tract. When spread by droplets or direct contact, the virus replicates in the respiratory tract and damages your host cells.

Most people can fight this condition effectively over time. However, people who have a lower immune response, such as people who are pregnant, very young, cancer patients, asthmatic, the elderly or those who suffer from pulmonary diseases, are not only more susceptible to catching the virus, but are more likely to suffer serious, potentially life threatening symptoms. It is estimated that between 250,000 and 500,000 people die from influenza each year.

What causes influenza?

Influenza viruses are divided into three types: A, B and C. Types A and B are responsible for the epidemics of respiratory illness that occur almost every winter, leading to outbreaks of illness and serious symptoms.

A type C infection is similar to a cold; it usually causes either mild respiratory illness or no symptoms at all. It doesn't have the same public-health impact of influenza types A and B. Most vaccination and preventative efforts are focused on the control of influenza types A and B.

Prevention and treatments

Natural recovery

The basic way to treat flu symptoms is the old fashioned way: stay at home and drink plenty of fluids. To help with fever, aches and pains, you should take paracetamol, aspirin, ibuprofen or other anti-inflammatory drugs. If you are still hot; sponge yourself down with tepid water and await natural recovery. Recovery usually takes a week, with some symptoms sometimes lingering for a further week afterwards.

Flu vaccination

Influenza can be prevented by an annual influenza vaccination. A flu vaccine (made from an inactivated and a sometimes non-infective variant of the virus) is specifically recommended for those who are at high risk of developing serious complications as a result of an influenza infection.

Over-the-counter medication

Over-the-counter medications are used to alleviate the symptoms of flu, rather than prevent its further spread. Medications such as antihistamines, decongestants and cough medicines can all help to relief symptoms, such as a runny nose, watery eyes, a sore throat and coughing.

Anti-viral prescription treatment

Prescription treatments are the only way to both prevent and treat the symptoms of flu. They can stop you from developing serious symptoms if you have come into contact with someone who has the virus, and can also relieve existing symptoms.


Tamiflu is an easy to take and convenient oral medication for treating and preventing influenza (flu). Tamiflu can prevent the onset of flu, even if the patient has been exposed to someone who suffers from it. Tamiflu reduces the severity of symptoms and infections, such as bronchitis, and also helps to reduce the duration of the flu by a day and a half, or more.


Relenza is a prescription only medicine for the treatment of influenza A and B in children and adults aged seven years and older. Relenza is inhaled through a device similar to an asthma inhaler every 12 hours for five days. Relenza helps prevent the virus from spreading in your body and may reduce the amount of time you are sick.

Finding treatment

As previously discussed, symptomatic treatments for the flu, such as decongestants and antihistamines, can be found easily over the counter in pharmacies. Many people choose to take antiviral prescription treatments as well, either in addition to these methods or as a preventative treatment. Tamiflu is a prescription medication that can be used either to prevent or treat the flu. It is available to buy online at HealthExpress after taking a short consultation.

How can I treat my Influenza symptoms?

The flu virus affects the respiratory system and for most people it isn't dangerous, however if you fall within a risk group or simply want to reduce recovery time, anti-viral treatments are an option. One available anti-viral treatment we provide is Tamiflu. This treatment not only treats influenza symptoms, but also blocks the spread of the virus, which confines the virus to a smaller area, allowing the immune system to kill the virus. This available treatment is approved by UK registered doctors and is clinically proven to effectively treat influenza. It can be easily and quickly obtained by completing our simple online consultation.
