Is it safe to stop 30mg duloxetine after 3 weeks without tapering? it was prescribed for nerve pain but is making my orthostatic hypotension worse. thank you?

The short duration of usage & low dosage should result in no expected side effects with discontinuation, but NEVER stop duloxetine on your own. This requires very careful medical supervision because the official prescribing information from Lilly and the FDA have been very careful not to provide clear and concise guidance on how to stop duloxetine.
