Tests typically monitored on Rogaine

Baseline labs before starting Rogaine establish the reference. Follow-up at 4–12 weeks is typical for most chronic medications, then annually if stable. More frequent monitoring is triggered by dose changes, new symptoms, intercurrent illness, or other interacting medications added to the regimen at 2%, 5%.
