Hi there, We are travelling to USA next April/May. At moment we will be in USA for 25 days, but away from home in West Oz for about 4 weeks.My son is epileptic and is liquid medication of 30mls a day. His bottles are glass bottles of 300 mls each.I will need to take at least 3 bottles - 1 bottle will last him 10 days, but I would also want to take 1 bottle as a spare - as we are doing quite a abit of travelling, it increases the chance of a bottle breaking or a slight spillage occurring.I willbe getting the letter from his doctor about the medication being necessary, and the pharmac_ have told me that they will package in some kind of protective wrap (I'm thinking good ole bubble wrap.)My query is will this be ok, or will I need to get them into to sealing bags? also, as 3 bottles is 900mls and 4 bottles is 1.2 litres , will I or for that matter anyone else take another liquid/gel onboard? I was hoping to take a small bottle of my makeup, some toothpaste, and some lip balm with me.I believe once we get through Immigration and Customes we can purchase a water or cool drink to take onboard.Of course I will be indicating on the custom form that we are bringing in medication, and I will have that letter, but just wondering, if there was any issue, they would surely pick it up at the Sydney internat. Airport before leaving, shouldn't meet with a problem on arrival should we? The bottle indicate that the medication should not be stopped without medical authority or stopped suddenly, so I cant see them being able to seize the medication - this is my one worry, that if they stop me taking the medication on board or seize it, son will need to take a dose on the aircraft, plus they are glass bottles, pharmac_ saidmcant put in plastic bottles as could affect the medication, so I cant pack the spare bottles in the checked in luggage due to possible breakages, plus luggage does get mislaid occassionally and I just cant take the chance.has anyone travelled to USA with large quantities of liquid medication in carry on luggage?PS we land at LAX if it makes any difference Thankyou.
