A few years back, I read that self-administered oral allergy treatment
was available in the UK.
I was bummed that we didn't have it in the states. The reason given was that if a person had a reaction to the serum (at home), he may not be able to administer epinephrine to himself in time.
Sounds like a weak reason to me. Can't breathe? Grab the epi-pen. Problem solved, yes?
I don't know the protocall of your health system in the UK, but ask around and see if you can score any info on the oral treatment.
