Hello

I apologise for asking a question if it has already been asked. If one buys items from duty free at LHR from a variety of shops i.e. world duty free and Jo Malone for example and are transiting through Doha can you have your duty free items put in one single sealed bag or two different ones? Also do you court any problems transiting through Doha with ibruprofen/codeine tablets (bad back and neck) which are bought OTC? I know that it codeine is a banned substance in Dubai. Or will it be ok? And also any problems with Gaviscon Advance or will it be fine? Many thanks for your help
