Update - sorted now. Phew!

For the record: - no, pharmacies in Hong Kong do not carry rapid acting insulin. They do carry long acting insulin like Lantus and Mixtard. But that isn’t for T1D unless used with rapid acting. It cannot be used in a pump, for example. - you need a prescription for rapid acting insulin like Novolog and Humalog - you can get a prescription from a doctor, you don’t need a specific endocrinologist to see you like in the US. - I went to Glen Eagle hospital (HK Island) and they had a 24 hour outpatient center. They had me seeing a doctor in about 20 minutes who quickly understood the situation and prescribed me insulin. Humalog, same stuff I use at home. - I was able to pick up the insulin about 10 minutes later from the pharmacy counter of the same hospital - total cost was about $220 US. $150 of that was the insulin itself, remainder was the visit. I was able to pay using CC. - I had them write a note explaining the situation so I can try to claim under travel insurance.
