The Subject That Convinced Me I Didn’t Belong

It was almost midnight, and I was staring at the word oxybutynin like it had personally wronged me.

I’d seen it maybe twenty times that week. Flashcard, missed. Practice question, missed. I knew it treated something with the bladder, I think, and that it blocked some receptor, and past that, my brain just went quiet. The library had emptied out around me. I still had two hundred medications to learn, and Step 1 (USMLE Step 1 is the United States Medical Licensing Examination, which consists of three required board exams that students must pass to practice in the United States) didn’t care how tired I was.

Here is the part no one warns you about before medical school. Pharmacology isn’t hard because the science is complicated. It’s hard because there is so much of it, and it all sounds the same. Hundreds of drug names that blur together, each one dragging a mechanism and a list of side effects behind it. You don’t understand your way through it. You memorize it, and then you forget, and then you memorize it again.

But the workload wasn’t what scared me. A classmate would rattle off what a drug did and how it worked, like the facts were just sitting there within easy reach. I would nod along, go home, and lose another hour trying to memorize a drug name that just wouldn’t stick. And the thought I couldn’t shake was uglier than just falling behind: that everyone else had been right about themselves, and I had been wrong, that somewhere in the admissions process I had fooled people into believing I was something I wasn’t.

By then, my nights had taken a shape that was not a good one. I would get to the library after dinner, open the same stack of cards I couldn’t memorize from the night before, and run through them until the words stopped meaning anything at all.

That night, too tired to do another flashcard, I did something dumb instead. I broke the word apart. Oxy. Butynin. Ox. Butting in. I pictured an actual ox shoving its way to the front of a waterslide, butting in, and blocking the water. That is what the drug does; it stops the flow. An overactive bladder, calmed down by an ox butting in. I never missed another oxybutynin question.

It sounds like nothing, but it felt like everything. For the first time in weeks, something had finally stuck.

So, I started doing it on purpose. I would take whatever drug was wrecking me that day and sit there until I found the story hiding inside its name. Pilocarpine became a pile of carp, wet, flopping, and dripping everywhere, which is more or less what the drug does to you. Colchicine turned into a piece of cold chicken, stiff and forgotten at the back of the freezer. My notebook filled up with these little scenes. They were silly, but they worked. For the first time, pharmacology stopped feeling like a wall and started feeling like a row of doors, and every door had a picture on it.

I sent one of my drug “story” ideas to a classmate who was stuck on the same drug I’d been stuck on. He sent it to someone else. A few days later, my phone buzzed with a text from a number I didn’t recognize: “Wait, that ox thing actually worked. Do you have more of those?” That was the moment it stopped being a private notebook.

By then, I knew the cost of being a medical student all too well. The study resources everyone swears by are good, but expensive, and pile up on top of a tuition that already keeps you awake at night. I had felt that math myself, sitting there deciding which expenses I could actually justify that month. The mnemonics had started as scraps I’d made to save myself. Putting them somewhere anyone could reach them for free felt like the only thing that made sense.

So, that’s what I did. One drug, one story, every Monday, open to whoever wanted it. I called it RxMnemonic, a weekly drug and the story that makes it stick. I figured a few friends might read it. Now, more than a thousand students now get it in their inbox every week. I still write every one of them at my desk, usually late at night when a new drug is giving me trouble.

I just started my third year, with a long way to go before anyone lets me call myself a doctor. But pharmacology showed me something I never expected to learn. For a while, it had me convinced I was not good enough to be here. Somewhere along the way, that flipped. I learned that the thing that almost breaks you might be what you come to understand most honestly, and the knowledge most worth handing to the person behind you. It is why I still write these. Somewhere out there, a student I’ll likely never meet will remember the right drug on an exam day, and like me, remember that they belong here after all.

And it all started with an ox, butting in, refusing to let anyone pass.
