Finasteride remaining calculator
Add doses with their amount and how many hours ago they were taken. The tool uses a finasteride half-life model to compute remaining amounts and draws a decay graph.
How to use the form
- Type — Standard uses typical doses (1mg for hair loss, 5mg for BPH); choose Custom to enter exact mg.
- Hours ago — how many hours have passed since you took it (use decimals, e.g. 1.5 for 1 hour 30 minutes).
