Hello
I am in the UK and this is what is
recommended here.
Sometimes a return to previous dose is enough, but if it’s got too bad then it’s recommended to add 5mg to the dose you last felt alright - stay there for 7-14 days and then drop back down to just above the dose you flared [not to the dose you flared as that is obviously too low].

As long as you don’t stay on the increased dose for longer than 14 days, it’s quite safe to drop back down. If you stay on it longer, you may need to follow a much slower taper.

Stay there for 3-4 weeks to make sure all okay before you try and taper again.

If inflammation has been allowed to build up significantly a staged reduction may be required.
