Match the clock to the drug: painkillers show within an hour, antibiotics within days (NHS checkpoint: day 2 to 3), antidepressants at 4 to 6 weeks, Flonase at 2 weeks, nail-fungus pills over months - and silent drugs (statins, BP pills) prove themselves only by the number or the event that never happens.
The method: at the start, ask what you should notice and by when, write it down, and judge at the checkpoint, not daily. The twin traps: quitting a slow drug in week one (its normal timeline, not failure) and staying on a fast drug past its checkpoint unchanged (that is failure - call). Start-up side effects arriving before benefits are normal and usually fade. Pymander is a free AI doctor, 24/7 by text, and can set the checkpoint with you.
What to do
Common questions
How do I know if a medication is working?
Every drug has its own evidence and its own clock - the trick is knowing both before you judge. The clocks, per the NHS and MedlinePlus pages behind this site: painkillers and antihistamines show within an hour; antibiotics for most infections show within a few days (the NHS checkpoint is day 2 to 3 for cefalexin and nitrofurantoin - not improving by then means call); antidepressants take 4 to 6 weeks at a working dose; Flonase takes up to 2 weeks; terbinafine for nail fungus takes months. And the silent drugs - statins, blood pressure pills, blood thinners - produce no felt signal at all: their proof is the number (cholesterol panel, home BP log) or the event that does not happen. The method: when you start a drug, ask two questions - what should I notice, and by when? - and write the answer down; then judge at the checkpoint, not daily. Two traps: quitting a slow drug in week one because nothing happened (that is the drug's normal timeline, not failure), and staying on a fast drug past its checkpoint without improvement (that IS failure - call). Side effects muddy judgment: start-up effects often arrive before benefits, and most fade within a couple of weeks - do not confuse early discomfort with the drug not working.
