you were bit by a bird. what med do you get

doxy (psittacosis)

macrolide abx MOA

irreversibly binding to the 50S subunit of bacterial ribosomes, thereby blocking translocation during protein synthesis

tetracyclines MOA

binds to the 30s ribosomal subunit

FLQ MOA

inhibiting DNA gyrase

sulfonamides MOA

inhibit folic acid synthesis by blocking dihydropteroate synthase

normal d dimer level

< 500

COPD + seasonal flu ( muscle aches, headache, and malaise)

→ oseltamivir
