You'll then be switched to tablets or capsules for long-term maintenance.

If your doctor feels you need rapid digitalization, your first few doses may be given intravenously.
A typical maintenance dose might be a 0.125 milligram or 0.25 milligram tablet once daily, but individual requirements vary widely.
