Instead I took aspirin twice a day for its supposed anti viral effect. On the second night I took an antihistamine and I woke up feeling fine after feeling awful the day before. They say it takes 5 to 7 days to clear up so

Apparently you can cause Reyes syndrome giving aspirin to kids so this is a suggestion for adult hfmd.
