Is It Safe For My Son With A Recent Middle Ear Infection And 4 Doses Of Augmentin To Ride Roller Coasters Tomorrow?

My son is 7 years old and was diagnosed with a middle ear infection on Wednesday. He has had 10 ml of Augmentin at night and in the morning since then. Today is Friday, so he has had 4 doses so far. Tomorrow we were wanting to go to a theme park to ride roller coasters. Is is safe for him to ride roller coasters?
