It appears that Tamiflu may have serious side effects such as Stevens-Johnson's syndrome and Tamiflu may linked to several childhood behavioral issues. Tamiflu may also cause nausea and nightmares in children. All of that being said, I wouldn't make the decision lightly to give any child Tamiflu daily to prevent the flu or H1N1. I think Tamiflu may be a life safer for some people, I'm just hoping for a safer alternative to the flu shot than Tamiflu.
