A hole in the week is not a homemade as-needed weekend
Three missed mornings do not convert the bottle into a Friday-only product. If you wanted rare doses, that is a regimen change with the prescriber. See daily versus weekend 20 if that is the real job.
Restarting Monday after a skipped weekend is a new climb toward steady state. Do not add a 20 mg 'loading' swallow to hurry it.
Missed-dose math does not lift a cap
Ketoconazole still holds daily use at 2.5 mg the day you remember. Clearance under 30 still turns daily use off. A remembered tablet is not a holiday from those rows. The tadalafil panel keeps the caps.
Nitrates stay banned on a late swallow the same as on a 7 a.m. one. Continuous exposure, even patchy, is still exposure.
What to say at the next visit
Count the holes. Four misses in ten days is an adherence review, not proof that 5 mg failed. Yuki Tanaka will not climb milligrams on a swiss-cheese clock.
Partners who hide the bottle 'to keep it medical' cause misses. A visible, boring spot beats a secret drawer. Page cites: [email protected].
When the next habit hour is already close
If you remember at the door of the next swallow, skip the late tablet and take the usual one. Stacking two hours apart is still two doses in one calendar day for most clocks.
Shift workers should attach 'day' to the sleep-wake block they actually live. A miss at the end of a night shift uses that block, not the wall-clock date alone.
The remembered swallow is the whole rule
If you miss a dose, you may take it when you remember. That sentence is the patient leaflet, not a Toronto custom. 2.5 mg remembered at 4 p.m. is still 2.5 mg. It is not a license for 5 mg 'to make up.'
Write the late hour on a slip so tomorrow does not drift to 4 p.m. as a new habit. The same-time scan is the clock page if Saturday keeps sliding.
Two tablets the same day is outside the miss rule
Do not take more than one dose per day. A morning 2.5 mg plus a remembered 2.5 mg at night is two doses. A 5 mg plus a leftover 20 mg is two regimens. Neither is a catch-up.
Accumulation toward the 1.6-fold line assumes one swallow per day. A double does not rebuild faster. It only raises the day's exposure.
