The TSA restrictions put in place after the thwarted terrorist plot in England last year on Aug. 9th, pertain only to liquids. If you have liquid medicine make sure it is in its original bottle and/or has its prescription sticker on the bottle.
I talked to the TSA at the airport and they told me this.
They also said, make sure you get rid of your bottles of drinking water,gatorade, cans of soda, and large bottles of shampoo and other large liquid toiletries before you get to the security checkpoint.
What is worse, is that some people arriving back from their cruise are still trying to pass their bottles of Duty-Free liquor with them through the checkpoint (instead of checking them in), that will end-up being a costly mistake.
