Starting the Drug Finasteride Slowly Over Week, Is That Reasonable?

Can I start building up the dose amount or frequency over time?  e.g. I’ve heard of people taking it EOD at first, or of amounts much smaller than 1mg. But I don’t know what’s safe in that regard, or if there’s any point in, say, taking 0.5mg a couple of times a week at first before building up.

Yes, you can start on a single pill (1mg) every fourth day for two weeks, then every third day for two weeks, then every other day for two weeks. If you don’t see any side effects, go directly to one pill every day.
