Svens, I created a storm at BOS a few months back on this and since then, not one TSA agent in BOS has said a word about my liquids. Be sure and declare, have your Rx printed out. Keep it separate from your freedom baggie, have the prescription, and place your freedom baggie and box of meds in one bin by themselves with the prescription. However, as a precaution, I'd slip a few ampules in your pants pocket to be sure you can get on the plane without any problems.
