About RxGuess

RxGuess is a free daily pharmacology game that helps pharmacy students, pharmacists, nurses, medical students, prescribers, and other healthcare learners keep commonly prescribed medications fresh in their minds. Each day there is one mystery generic drug and five guesses. Every wrong guess unlocks a new clinical clue.

The game is built on active recall: instead of rereading flashcards, players reason from a side effect, an indication, or a mechanism back to a specific drug — the same kind of thinking used when reviewing a medication list or answering board-style questions. Rx Blitz, our 15-second brand-vs-generic speed round, adds quick name-recognition practice for the most commonly dispensed products.

The library covers more than 380 medications, focused on frequently prescribed outpatient drugs plus high-yield hospital agents (antibiotics, anticoagulants, vasoactive drugs, and more). Each entry includes the generic name, a common brand name, the pharmacologic class, a primary indication, and five clues.

Wrong-answer choices in the search list include look-alike and sound-alike names and same-class neighbors, because telling similar drugs apart is a real medication-safety skill.

Every puzzle moves from broad to specific so that players who know the drug well can solve it early, while learners still get a fair path to the answer:

1. 1Side-effect signal. A characteristic adverse effect that points toward a few drug classes without naming one.
2. 2Indication & route. What the drug treats and how it is given or formulated, narrowing the clinical setting.
3. 3Mechanism of action. The pharmacologic target, which usually makes the drug class clear.
4. 4Clinical pearl. A clearer safety, monitoring, or interaction point that separates the drug from close relatives.
5. 5Drug-specific fact. A distinguishing detail — a landmark trial, kinetic property, or unique use — that singles out the answer.

Clues avoid letter counts and spelling hints, and we check that no two clues in a puzzle repeat the same fact.

Clue content is drafted and checked against widely used, reputable references:

• FDA-approved prescribing information, accessed through DailyMed (U.S. National Library of Medicine)
• Professional society guidelines such as those from the AHA/ACC, IDSA, and ADA
• Published landmark clinical trials when a clue cites trial evidence (for example, SADHART or ODYSSEY OUTCOMES)

Clues are written with AI assistance and then reviewed and edited by hand. Upcoming puzzles are reviewed before they go live, and the full clue set is periodically audited for accuracy, repeated facts, and clues that give the answer away too early.
