How Soon Do People Experience Heartbeat SideEffects w/ minoxidil

[Logic1]

Is this a side-effect that takes a couple weeks.....months to notice...or is this a side-effect that typically begins directly/shortly after application?

Thanks

I think I felt something the first 2-3 times I used the foam, and that was it.

The rapid heartbeat must be due to systemic absorption of the minoxidil. I experienced water retention and rapid pulse from 1 ml twice daily. I am currently trying it again after a 6 month layoff. For the past week I have been applying 1/2 ml 2 times daily. No negative effects so far from this lowered dosage. :hairy:

It normally happens within minutes of applying.. but that stopped happening after a few months of minoxidil.
