I Have been on IV antibiotics and was discharged from hospital yesterday, now this is what my Picc looks like, I am in emergency as my arm is really hot and feels like it is on fire, I am having heart palpitations, am extremely tired, supper nausea and 8 mg of zofran is not covering it. As well I n
I have a patient with a history of multiple myeloma, currently in remission about a year after autologous stem cell transplant, currently in pomalidomide maintenance. PMH is notable for multiple DVTs and PEs and probably an undiagnosed hypercoagulable state, for which he's on warfarin. Also paroxy

When I'm reconning ceftazidime/avibactam(avycaz) there is a ton of positive pressure in the vial after the powder fully recon's. I know that's normal, however, I notice after a short while, maybe an hour, the bubbles go away and there is no more positive pressure in the vial, even if none of the sol
My Dad has been an alcoholic for decades and has been drinking every night since he was 25 years old. There have been moments in the past several months when we had to have him checked by physicians because we were worried about his health, given that he is not getting any younger. Surprisingly, his
Nurse here. I have a question for reconstituting ceftazidime via IV push. I notice specifically for this medication, when I inject 20 ml’s of sterile water into the vial, it seems like there’s carbonated bubbles once I draw it back into my syringe. It also leaks a whole lot. I don’t inject any addi
Hi everyone, and sorry for the photo (in the comments). A relative developed (F30, no smoker) a wound on their hip after an afternoon at the beach. This happened in July. We went to the ER, and a plastic surgeon also examined it. They were prescribed antibiotics and painkillers (amoxicillin, flucona
Howdy, nerds. Anyone know why the ceftazidime package insert indicates that vials should be reconstituted with SWFI, and then diluted further with NSS? Can I just use NSS for the initial recon? Most importantly, can I use a mini-bag? TYIA.

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
I’m a 71F (5’2”, 190 lbs, non-smoker/non-drinker, no regular medications) and I’ve had recurring swelling of my eyelids since last May that has been getting worse with each flare. Both upper eyelids become red, swollen and very itchy (not painful) and more recently the skin has started to crack, wee
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. [Here is what the pinky finger looks like](https://imgur.com/a/NAzODn0) (note: it looks sli
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. Then a general swelling started the day after, in that area. That evening I had pretty intense chills while going to bed and the next mornin

Can someone explain the point of this to me? Assuming you're treating cellulitis. Bactrim would cover both MRSA and MSSA...keflex would cover MSSA... So if you think there is a risk of MRSA why not just do Bactrim. Or, if you think MSSA why not just do Bactrim. Why do both? I did a quick uptoda
