Unusually long antibiotic prescription?
I'm asking on behalf of my friend. They recently went to the ER (for a workplace injury completely unrelated to lyme) and the doctor noticed a bullseye-like rash on their arm. My friend hadn't noticed any other symptoms of lyme (though after they told me about all this, I pointed out that they had been drowsy all week, though they'd been attributing that just to stress). They're still waiting on test results to prove that it's lyme, but the doctor decided to prescribe antibiotics in the meantime, just in case. That makes sense, but the prescription itself is strange: *10 weeks* of doxycycline. That's not only more than the 10-14 days recommended by the CDC, but it's double the 4-6 weeks recommended by ILADS. Does anyone here know why that timeframe was chosen?
