The purpose of this study is to determine whether 24 hours of Terlipressin is as effective as 72 hours of Terlipressin in preventing re-bleed once esophageal variceal bleed has been controlled with endoscopic therapy (variceal band ligation or sclerotherapy) in low to moderate risk variceal bleed patients and hence can save cost and may decrease length of hospital stay especially in the I.C.U or high dependency units.
