01Does a heavy dinner ask for a second tablet?
No. One tablet once daily is the cap the hair label writes. A large meal does not waste the swallow. Taking a second 1 mg because dinner was late is not on the label. The how much finasteride page stays on that single milligram. If the evening dose is the habit you remember, keep that slot. The meal beside it does not rewrite the strength. Food did not change bioavailability in the 1 mg work. There is no labelled 'make-up' tablet after a feast. One 1 mg swallow is still the daily cap after a large meal.
02What does the Administration line say about meals?
Propecia may be administered with or without meals. The recommended dose is one tablet (1 mg) taken once daily. Those two sentences sit together. There is no labelled hold before breakfast and no labelled hold after dinner. The hair wait of three months or more still starts from daily swallows, not from an empty-stomach clock. If evening is the slot you remember, dinner can sit beside that swallow. The meal does not rewrite the milligram. A fasted morning is allowed for the same reason a fed evening is allowed.
03When does plasma peak after a swallow?
At steady state after 1 mg a day in 12 men, maximum finasteride plasma concentration averaged 9.2 ng/mL (range 4.9 to 13.7). That peak was reached 1 to 2 hours postdose. AUC over 24 hours was 53 ng hr/mL (range 20 to 154). Those numbers sit next to the meal sentence. They do not add a fasting rule. A late dinner does not push that 1-to-2-hour peak into a second tablet. The peak is a plasma clock, not a meal timer. Steady state here is the daily 1 mg habit, not a loading pair.
04Does breakfast change how much is absorbed?
Bioavailability of finasteride was not affected by food. Mean bioavailability of the 1 mg tablet was 65 percent (range 26 to 170 percent) versus an intravenous reference dose in 15 healthy young men. That 65 percent is an absorption number. It is not the 65 percent DHT suppression seen in serum at 24 hours. A fatty breakfast is not a reason to raise the milligram. The hair label does not write a different 1 mg for a fed day and a fasted day. One tablet is still one tablet. The 15-man bioavailability look used an intravenous reference, not a meal challenge that changed the dose.
05Does a meal change the three-month hair clock?
No. Daily use for three months or more is necessary before benefit is observed. That clock counts daily tablets. It does not pause because lunch was skipped or because dinner was large. Investigator scores moved as early as 3 months on daily 1 mg, not on a fasting protocol. Eat or don't eat. Keep the once-daily line. A week of 'empty stomach only' does not pull the hair read forward. The Dosage wait is daily use, not meal timing. Self-assessment questions also used daily swallows, not a meal hold.
06Can I crush the tablet into yogurt?
Keep the tablet intact. Women who are or may be pregnant must not handle crushed or broken tablets. The film coat is what keeps the active ingredient off skin during normal handling. Yogurt is not a labelled mix. If a tablet is already broken, it is a handling problem, not a snack. The pregnancy ask covers wash-off if dust touches skin. Soap and water is the labelled wash if crushed dust touches someone who is or may be pregnant. Ask the pharmacy for intact 1 mg tablets after that.
