It’s not really a secret- I love toxicology. It is just so complicated and interesting. My ED sees a lot of overdose but usually not from prescription medications. Recently I had a case where a patient had ingested what looked like a bag of skittles. The usual suspects such as zopliclone and seroquel but the really trouble was the metoprolol which my smart ER doc quickly picked out of the bag. It’s a hard thing to manage and absolutely not something you see every day (thankfully).
A short but sweet post on betablocker overdose. Not a ton of details on treatments but a good generalized look at your options.
