Yes, it’s safe. In clinical studies, Tamiflu was given to 1,994 people who were ages 65 years and older, including 1,048 people ages 75 years and older. There were no differences in the safety or effectiveness of Tamiflu in these age groups compared to the safety or effectiveness seen in younger people taking the drug.
If you’re over the age of 65 years, and you’re interested in taking Tamiflu, talk with your doctor to see if it’s an option for you.
