My Dd and I have used Meclizinie HCI chewable tablets Since she was Little[me before she was born!!]
I went to the pharmacy in Wal-Greens and ask the them for the MECLIZINE HCI 25mg chewable tablets.and I get a bottle of a 100 tabets. you can use this motion sickness pill to pervent illness when flying or in the car,on a boat, any time you feel that yikky feeling. and you can take it even after you start feeling sick and it cures the motion sickness!! Even at WDW!!
I use 2 tabets and I can ride Space Mountain or Rocking Roller Coaster with out a Queezy Moment and no drooziness!!!
When Dd was young [4yrs old]I gave her 1/2 tablet,but If she started to feel yucky I would give her an other 1/2 . Ask your ped's Dr. for a dosage for your child.
Start giving it the night before you fly out! and every night of your trip, that way if there is any sleepyness your child is over it by morning!
Mechlizine HCI is the genaric for Bonine which is a really expesive for 8 tablets!!!
