Not the same as a natural disaster, But I have found myself with no meds.
I was on holiday visiting the USA a couple of years ago, I was in Oregon/Washington doing a roadtrip, I always take plenty of meds away with me, more then enough. It wasn't until Sunday night in the middle of nowhere that I discovered that ALL of my meds were gone.
I cannot think of anyway that was possible as they were not all kept in the same backpack, I can only assume that they were stolen that morning from my motel room when we went out for breakfast. As everything else that I kept in the first aid kits etc was still there. I had no evidence so I couldn't report it, also by the evening I was 500 miles away from the motel.
There was no local doctors or pharmacy, so we had to find the closest hospital which was 50+ miles away from our hotel that night. Once there, I went into A+E and spilled the story about the missing meds. I had a hard time convincing the doctors that I needed the meds, they weren't just going to let me have a prescription for them, I might have been a con artist. I had nothing on me to say that I am epileptic and I use xxxxxx medication.
In the end they relented and handed me a prescription, after doing a full medical, they pointed out that my blood pressure was high and I pointed out to them about the fact that I have no medication, I still have over 2 weeks left of my trip and they are digging their heels in about handing me a script, I said "don't you think that this would increase your blood pressure?"
Then next challenge, finding a pharmacy open in a sleepy town, late on a Sunday night, I did manage to find one, but they handed me Lamotrigine instead of Lamictal, which was unfortunate but at least I had some meds.
The whole scenario was very costly so thank god for travel insurance.
But this opened a new subject for me, why in the UK do we not have medical cards that states conditions and medication??? as this could have been so much easier.
