Description
Tamiflu, known by its active ingredient oseltamivir, is an antiviral medication used to treat and prevent influenza, commonly referred to as the flu. It is not a general cold remedy, but rather a targeted treatment that works against influenza virus types A and B, which are responsible for seasonal flu outbreaks.
Tamiflu works by inhibiting the neuraminidase enzyme, a substance the flu virus needs to spread from infected cells to healthy ones in the body. By blocking this enzyme, Tamiflu helps to limit the spread of the virus, which can reduce both the severity and duration of symptoms such as fever, chills, sore throat, muscle aches, and fatigue.
The medication is most effective when started within 48 hours of symptom onset, though it may still offer some benefit if taken later. It is commonly prescribed for individuals at higher risk of flu complications, such as older adults, people with underlying health conditions, or those with weakened immune systems. In some cases, Tamiflu is also used as a post-exposure prophylaxis for people who have been exposed to the flu but are not yet symptomatic.
Tamiflu is typically taken as a five-day course, with a capsule taken twice daily. For prevention, a once-daily dose over ten days is common following close contact with someone who has the flu.
Most people tolerate Tamiflu well. Some may experience side effects such as nausea, vomiting, headache, or abdominal pain, particularly at the start of treatment. Taking the medication with food can help reduce stomach-related side effects.
General Information
Tamiflu is the brand name for oseltamivir phosphate, an oral antiviral that blocks the neuraminidase enzyme on influenza A and B viruses, halting their spread inside your body.
- Treatment: Shortens flu illness and lowers the risk of bronchitis, ear infection, or hospitalisation when started early
- Prevention: Protects close contacts after exposure - particularly valuable in nursing homes or family households
Newly replicated flu viruses need neuraminidase to cut themselves free from host cells. Tamiflu's active metabolite binds that enzyme so viruses remain stuck, fail to infect new cells, and die in place.
For adults 75 mg twice daily for 5 days (treatment) or 75 mg once daily for 10 days (prophylaxis).
Fever often drops a day sooner; cough and malaise improve by the second day if started within 48 hours of symptom onset.
Take it as soon as remembered unless the next dose is due within 2 hours. Do not double dose. Complete the full 5-day course even if you feel better.
Safety & Side Effects
- Very common: nausea, mild vomiting (take with food).
- Common: headache, stuffy nose, tiredness.
- Occasional: cough, ear discomfort, abdominal pain.
- Rare but serious: severe skin reaction (erythema multiforme), hallucinations, confusion, especially in children. Report abrupt behaviour changes.
Yes. Stop at once and seek help for rash, itching, facial swelling or breathing difficulty.
Few. Live-attenuated intranasal flu vaccine should be given 48 hours before or 2 weeks after Tamiflu or it may be inactivated. Warfarin, anticonvulsants, and hormonal contraceptives are unaffected.
Occasional dizziness or confusion has been reported; be cautious until you know your reaction.
Yes. CDC and WHO recommend Tamiflu for pregnant women because flu complications are higher. It passes into milk in tiny amounts and is considered compatible with breastfeeding.
Prophylaxis longer than 6 weeks may be needed during outbreaks but must be supervised to watch for resistance.
No direct interaction, but alcohol dehydrates and can mask fever. Best avoided when acutely ill.
Usage & Administration
Swallow capsules whole with or after food. For suspensions, shake well and measure with the oral syringe. Store capsules below 25 °C; suspension in the fridge (2-8°C) once prepared.
Nausea or vomiting may occur; serious toxicity is rare. Drink fluids and call a poison centre.
Do not take Tamiflu if allergic to oseltamivir or any capsule component. Caution in severe kidney disease, hereditary fructose intolerance (suspension), and uncorrected immune deficiency where resistance may emerge.
