I've noted the discussions here about Non Steroidal Anti-Inflamatory Drugs (NSAIDs) and a reported increased risk of serious bee sting reactions in people who have not previously experienced problems with stings, particularly beekeepers. The gist as I understand it of it has been that drugs ending in 'phen' are implicated. This includes, I assume, Acetaminphen as well as ibuprofen ("...fen" = "...phen"?) as well as their higher power prescription relatives. Recently, I have taken normal label recommended doses of ibuprofen on occasion and gone working bees -- and been stung with no ill effects. I think I heard that the dangers are associated with *large* doses of these drugs, but I don't know and I think that this area is not too well understood. Recently I have been prescribed Arthrotec, an anti-arthritic drug for back problems and swoolen sore hand. The stuff really works. So much for beekeepers not getting arthritis. Anyhow, I've looked around and see that this drug does not seem to be of the "...phen" family. A web search brought me this: "Arthrotec is a new product that combines the NSAID diclofenac and the prostaglandin analog misoprostol. The diclofenac component of Arthrotec is responsible for the relief of the symptoms of arthritis. The misoprostol component is responsible for the mucoprotective properties. Arthrotec has the dual purpose of relieving the signs and symptoms of arthritis and protecting patients from the development of gastric and duodenal ulcers"... I'm not taking massive doses, but I'm wondering what people know about this drug and any dangers. allen http://www.internode.net/HoneyBee/
