Acetaminophen elders. Acetaminophen is extremely safe and is the safest mild pain or fever medicine that elderly persons can take. The only concern would be if the elderly person has severe chronic liver disease or chronic alcoholism or takes more than 3000 mg a day for a long period of time.
Lower dose. The maximum dose for Acetaminophen has gotten lower over the years, as there has been more liver problems related to it, at even what we though were 'safe' doses. The maximum dose is 2.4 gms a day and probably less for someone that is frail or who drinks alcohol (.
