Keeping up with "who's on first" in the epinephrine auto injector world takes some effort! Just this week I talked to Dave Perry of Lincoln Medical in England [UK]
Dave informed me that the withdrawal of their autoinjector was voluntary and that the voluntary withdrawal has ended with Anapen now being available again in UK and much of Europe. Anapen is listed as available in 36 countries.
Currently there is no distributor listed in Canada. I wonder if that is because Epi is not prescription but over the counter in Canada under Sabrina's law. That law was passed when a child died from lack of then prescription EPI.
Anapen is the only auto injector with a stronger dose for larger people of .5 mg. See more info here.
