In the context of a code/rrt when the patient has a prolonged qtc or is on dofetilide, sotalol, etc- if they need lidocaine or amiodarone, do you steer away from amiodarone and pick lidocaine? Assuming they are both available. Do you not even ever take the qtc/sotalol into account during a code? Per
Hi r/pharmacy community, I’m a hospital pharmacist tasked with the duty of establishing dofetilide initiation guidelines for my local hospital. Wanted to reach out to see if any other fellow hospital pharmacists can provide me with a copy of their guidelines that they follow at their hospital just s
Has anyone tried Dofetilide? I had my 4th ablation back in August and it didn’t work. I am definitely over ablations at this point as all 4 have had complications. My EP recommended Dofetilide, but I have to do a 3 day hospital stay when starting. Been through plenty of drugs and they either don’t w
EP is recommending Dofetilide, but I've read several medical reviews/journals thst say people with paroxmayl afib that self corrects in less than 24 hours, shouldn't take it. I am symptomatic when it happens, as in I can feel the second it starts and it does cause chest discomfort. I am that person
I was admitted to the hospital yesterday. Turns out I’m in AFIB yet again. My EP has started me on Dofetilide. Because I’m this is twice in three months. Does anyone have any experience with this medication.

37m 5’7 feet tall 165 pounds No medications I have paroxysmal afib with RVR with a few episodes per year. Had a very jarring experience at the ER and my primary care doctor found out about it and got very angry. Looking to see if anyone has heard of cardioversions without any sedation During an
Hey all! I had my ablation done today. I wanted to share my experience with you all since I’m a frequent poster and had major, major anxiety going into it. For context, I had a 14.7% PVC burden managed by Flecainide. Because I didn’t want to have to take Flecainide for the rest of my life, my dr an
I'm not sure what compelled me to write all of this, but I hope it will help someone. I'm sorry it's so long! TLDR: Im 33, tall, white, cis-man, scandinacian heritage, live in USA. I've experienced PVCs for years. Getting sober didn't help. Meds helped reduce how "hard" or papable the PVCs are. Elec
My first time having afib was June 2023. I went to nap after having lunch and I felt my heart beating out of rhythm. I was freaked out and checked my Apple Watch, did the EKG and it showed AFib. I didn’t believe it so I went to urgent care, they did another EKG which confirmed the afib so I had to g

Yesterday I caught a QT interaction between donepezil and flecainide, and a few days beforehand a donepezil x azithromycin interaction which ended up seeing the azithro withdrawn. Donepezil has good documentation for causing Torsades des pointes with agents like amiodarone or citalopram, but I'm not
Before my ablation I read many posts and they helped me a lot so I’m sharing my experience and hope it will help others especially because my case was successful.
