Clear Pharmacology, also known as the Clear Pharmacology Line Desk, is an independent educational resource that translates prescription information into concise, practical medicine notes. It does not sell or dispense drugs, accept sponsorship, or provide clinical care. Its pages organize information around a medicine’s mechanism, timing, featured strength, interactions, potential harms, and important precautions, using FDA labeling and cited trials as reference points.

The site covers eight medicines, including sildenafil, tadalafil, vardenafil, trazodone, finasteride, ketorolac, mebendazole, and ivermectin. Its five guides address topics such as comparing erectile dysfunction medicines, how PDE5 drugs work, trazodone for sleep, finasteride and hair loss, and short-term NSAID use. Clear Pharmacology emphasizes distinctions that can be overlooked, including different strengths for different uses, the need to avoid PDE5 medicines with nitrates, and ketorolac’s five-day limit across oral and injectable use.

The material is intended for education, not as an order or substitute for a prescriber; readers are advised to check current labeling and consult their clinician
