usually when a prescriber writes macrodantin 100 mg bid, i generally call them up and they're okay with changing it to macrobid 100 mg bid. but today i talked to a dr who pushed back a little bit (although still very polite and professional.) I said my usual spiel about how out of the 2, macrobid i
Tell me what would you do? The caveat is I told them we’re closing in 5 minutes and it’s not a good idea to call the Dr now (on the phone) ) to send it at our location and that there’s a 24 h pharmacy a block away. At 2 minutes she shows up and tells me Dr just sent it? And what if the line was long
Hey! My wife (F29) got a blister on the pinky finger a few days ago. Initially we both thought it was just a blister, but it has progressed quite significantly now to the point where we are unsure what it is.

So, I went to urgent care on Monday since I noticed a few things were happening. My first symptom was two swollen lymph nodes on the back left side of my neck.

How long is a reasonable treatment duration for chronic osteomyelitis? I have a patient due to receive one year of cephalexin 500mg bid. Treatment guidelines say typical discharge oral antibiotic therapy is 8 weeks. I know the disease course can be relapsing, but do some people receive prophylaxis?
See relevant reddit post in a DarkNet sub [here](https://redd.it/3cp4vl). Basically, you can find cephalexin 500mg, amoxicillin 250mg, penicillin 500mg, etc. OTC in pet stores. I had no idea this was a thing. A couple Google searches for these products confirmed it. Obviously, I'm not going to reco
My favorite are the Cephalexin and Amoxicillin Suspensions because you just slap a label on them (and when you mix them it smells good). My least favorite is a tie between Warfarin and Spironolactone. I hate the scent of Spironolactone and hand counting Warfarin is a pain in my ass.
