I don't know. Wrong spelling? Tamilflu is a prescription flu medication...it worked for me and my teen son... and Theraflu I think is OTC and it didn't work for my son...comes in a tea and capsules.
Take Tamiflu within 48 hours of flu symptom onset. ... Tamiflu is a prescription medicine used to treat the flu (influenza) in people 2 weeks of age and older who have had flu symptoms for no more than 2 days.
I believe that is the flu vaccine administered thru a nose spray
