What shrinks hemorrhoids fast?

Quick Answer
To shrink a hemorrhoid, target the swelling: a phenylephrine cream constricts the swollen vessels over one to three days, cold compresses and sitz baths reduce inflammation, and softer stools stop the straining that keeps it swollen. Lidocaine relieves pain but does not shrink tissue. Persistent or prolapsed hemorrhoids that will not reduce should be evaluated for an office procedure.
Shrinking is different from numbing. The active that actually reduces swelling is phenylephrine, a vasoconstrictor found in Preparation H’s flagship ointment; it tightens the swollen vessels over one to three days of consistent use. Cold compresses for the first day and warm sitz baths afterward reduce inflammation, and softening the stool removes the straining that keeps re-swelling the vein.
Lidocaine, by contrast, silences pain but leaves the hemorrhoid exactly as swollen, so it is not a shrinking agent. Internal vein-support flavonoids help the swelling over weeks rather than hours. If a hemorrhoid stays prolapsed and will not reduce, or does not respond to conservative care, that is the point to see a doctor about banding or another office procedure.
