Switching finasteride from topical to oral

I’m planning on making the switch from topical to oral fin (been doing min/fin solution for about a year). Anything I should be mindful of when making the switch? Google results are mostly on Min when I search it up. Does it take time for the oral version to take effect? I’m guessing having a overlap period would be a good idea.

From my experience you can quit the topical and go directly to the oral with no consequence.
