For older people who don't have liver problems, experts widely believe that up to 3000 milligrams (mg) of acetaminophen per day is safe, even if one takes this amount every day. That's equivalent to 9 tablets of regular acetaminophen (which is usually 325mg/tablet).
Tamiflu (oseltamivir phosphate) is an oral anti-viral drug approved for the treatment of acute, uncomplicated influenza in patients 2 weeks of age and older whose flu symptoms have not lasted more than two days.
Tamiflu: Oseltamivir belongs to the family of medications called antivirals. It is used to treat the influenza viruses that cause the flu. It works by inhibiting an enzyme the flu virus needs to spread through your body. If it is used within 2 days of the start of flu symptoms, oseltamivir can reduce the time it takes for flu symptoms to improve by about one day.
