Hey guys, I'm finishing my P2 year of pharm school eventually working in independent retail and this question has yet to be addressed: What are the top 10 (or top 5) ABSOLUTE contraindications that are often seen/relevant to retail/commonly missed by physicians? PharmTimes did an [article](http:/
Hello! I went to my doctor about 6 weeks ago due to moderate to severe testicular pain (the right side specifically) and was tested for STDs, STIs or other urinary issues and all came back clear. I was given antibiotics and an ultrasound was ordered. The ultrasound showed a 10mm lesion on my right t

I am a 61 y.o. male, 5'10", 209 lb, white. I smoke a cigar almost every day outdoors (do not inhale). I have a couple of drinks a week, I do not use other drugs. Also, I do resistance training almost every day and walk about 5 miles per day. So although my weight seems fairly high, I have more t
I was involved in an explosion a few years ago. I was burnt and whatnot and knocked around, but I don't think I ever lost consciousness from it. It was a pretty forceful explosion - it left a small crater in the concrete and knocked people over several metres away. The stuff I was holding in my hand

Hypothetically if a young, healthy adult ingested the smallest, available strength of each tablet/capsule in a standard retail pharmacy would that be enough to kill you? The big issue I can think of is the combination of QT prolongation, DDIs, and bradycardia could cause some lethal arrhythmias? Edi

Going to a small get-together for new years, and the poison ring I bought myself came in JUST in time! Cant wait to discreetly take my mid-party naproxen without having to fish through my purse! Happy new year everyone, may 2026 hurt less than 2025 🥳
I have so much wrong with me. Like it’s genuinely whole body at this point. Back pain, internal tremors, migraines, stomach issues, fatigue, heart palpitations, dysautonomia, rib pain, brain fog, vertigo, muscle inflammation, hands aching, pain that covers my whole body, knees hurting. I could keep
I'm hypermobile and fat and this has caused me to develop osteoarthritis in my hip, normal NSAIDs don't work on me and I'm allergic to naproxen. I'm scared of becoming addicted to opioids because they seem to be the only thing that helps but I've already gotten 2 prescriptions of them and I'm curren
This is more of a rant I guess. I've been struggling with pain for over a decade now, and no matter how bad it gets, I'm given naproxen or acetaminophen. Naproxen doesn't work for me, and it requires high doses of acetaminophen for me to get a small amount of relief. But they are still the only pai
Had a flare up today and usually when this happens I can’t walk. I usually end up in the ER because when I call my doctor I always get “we can’t help you unless you come in” Ma’am you diagnosed me and all I need is a steroid pack and some naproxen to reduce swelling. So when I was finally mobile eno
one more time. I’m going to scream. Anyone with me?
I have chronic pain along with fatigue and other issues and a majority of my pills are for my pain my doctors are trying me on so much before actually giving me anything to relieve the pain. I asked for 500mg naproxen and was given a muscle relaxer to take 3 times a day i’m up to at least 12 pills a
Hey everyone! I’ve been seeing a lot of posts lately in this sub and in others about people asking for little things that help manage the pain, so I thought I’d compile a list of stuff that helps me and others can tack on what helps them in the comments. I hope someone finds this useful! - **Prescri
