I've just been put on heparin injections which I have to do myself daily until my baby is born in February. I've been given boxes of the needles which come pre-loaded with the heparin and which are in individually sealed packs. Problem is, I live abroad and am flying back at the end of December and a bit worried about whether I can take one hand luggage or whether I will get problems at security? All my supplies I will split between my suitcases and hope they arrive ok but I will have to inject on the flight due to the strict timings I've been given. Has anyone got any experience of flying with needles? TIA
