Propecia dosage guide: how much to take and when
Choosing the right dose of Propecia (Finasteride) is the most important practical decision after starting therapy. Propecia is supplied as tablet in 1mg, and the right dose for a given person depends on the indication, age, comorbidities and tolerance to the active ingredient Finasteride.
Starting dose and titration
According to the prescribing information, most adults begin Propecia at the lowest available strength of 1mg and titrate up only if symptom control is insufficient and tolerability is good. Higher doses are reserved for selected cases. Older adults, people with renal or hepatic impairment, and those taking interacting medications should usually start at the lowest dose.
When to adjust
Dose adjustment is guided by symptom response and side effect burden, not by arbitrary schedules. DHT, produced from testosterone by 5-alpha-reductase, drives miniaturisation of scalp hair follicles in genetically susceptible men, gradually shortening anagen growth phases until follicles produce o… If side effects are limiting at a given dose, going down a step is usually preferred over stopping abruptly. If the response is incomplete after several weeks, a higher dose can be tried under medical supervision.
Frequently asked questions
What is the standard starting dose of Propecia? ▾
Most adults start Propecia at the lowest strength of 1mg, with adjustment based on symptom response and tolerance. Older adults and those with reduced kidney or liver function generally start lower. The prescriber decides the exact starting dose for each person.
Can I take a higher dose of Propecia if it isn't working? ▾
