Worth knowing while taking
Information is based on the oseltamivir reference prescribing information (the US Tamiflu label), which lists the same 45 mg capsule.
The 45 mg strength is for children aged 1 to 12 years weighing more than 15 kg up to 23 kg. The reference information has no adult dose that uses the 45 mg capsule (adults with normal kidneys use 75 mg).
If a capsule cannot be swallowed, the reference information prefers the oral suspension.
Children below or above this weight range use another strength of the same medicine. Adults use 75 mg, and people with reduced kidney function need a lower dose. Ask a doctor or pharmacist before use.
