I thought you knowledgable people might know about this.
I know that in order to take liquids in hand luggage when travelling abroad, they must be in containers of 100ml or less. I use oestrogel in a pump bottle - nowhere on the bottle or in the leaflet does it have a volume measurement. It says 750 micrograms/80 gram/0.06% I expect that the bottle capacity is greater than 100 ml (2 pumps per day last a month) based on the size of some toiletry bottles.
The obvious answer would be to pack it in hold luggage, but I'm worried about what happens if the suitcase gets lost. I suppose the answer may be to attempt to get a copy of my prescription from the GP (and hope that would be enough to allow it in cabin baggage) but I don't receive a paper prescription - it is electronically sent through to the local chemist, and is not a repeating prescription, so the chemist does not provide the repeat prescription form.
If you have travelled abroad with pump-dispensed gel, what did you do?
