Flu is a viral infection, which affects the nose, throat and lungs. The virus that causes flu is known as the influenza virus. Most people with flu have mild to moderate infection, which does not need a visit to the doctor. If you consult a doctor for flu, the doctor will most likely prescribe symptomatic treatment. As flu is caused by virus, there is no need for antibiotics.
Treatment for flu: In most cases of flu, symptomatic treatment is needed as it is a self-limiting illness that improves in a few days.
Symptomatic treatment, which makes the person with flu feel better include:
Antiviral medications: People with severe infection or those likely to develop complication are given antiviral medications. Antiviral medications used for the treatment of flu are:
Amantadine and rimantadine are not used any longer for the prevention or treatment of flu (as resistance to both these drugs has become common). Antiviral drugs have been shown to shorten the duration of illness by a few days. These drugs are most effective when started within 1-2 days of the start of symptoms. If you have symptoms of flu that do not improve with rest and symptomatic treatment, your symptoms are severe or you are likely to develop complications of flu because of some other problem, such as heart disease, diabetes, lung disease, etc, consult your doctor.
