This research aims to describe the characteristics of patients with chronic kidney disease who consumed calcium. This is a descriptive research type, the data retrieval  retrospectively from kidney hypertension sub specialist polyclinic at Ulin Banjarmasin Regional Public Hospital. The inclusion criteria of research subjects are patients with chronic kidney disease (stage1-5) who consumed calcium at the age ≥ 17 years old and the exclusion criteria of research subjects are patients with incomplete / not found medical record. The data of 313 research subjects is taken and analyzed descriptively. The result and conclusion is that the characteristic in the form of age 17-25  (years old)  (1.92%), 26-35 (7.03%), 36-45 (21.41%), 46-55 (37.38%), 56-65 (25.24%) and > 65 (7.03%) years old; male gender (51.76%), female (48.24%); the main cause of stage 5 chronic kidney disease (100%); comorbidities of hypertension (44.40%), hypertension+1comorbidities, hypertension+2comorbidities (15.01%), hypertension+3comorbidities (2.88%), hypertension+4comorbidities (0.32%), diabetes melitus (1.60%), anemia, dispepsia, hiperurisemia (0.32%), without commorbidities (2.88%); long suffered < years (92.01%) and ≥ 5 years (7.99%); the calcium used is calcium carbonate (99.68%) and combination of calcium carbonate and calcium lactate (0.32%); frequency of calcium consumption 3 x 1 (99.36%), 2 x 1 (0.32%), and 3 x 2 (0.32%); administration time of 7 days (2.24%), 10 days (1.28%), 15 days (0.32%) and 30 days (96.17%), with side effects (5.75%) and without side effects (94.25%); the accompanying drugs used antihypertensive (ARB, CCB, diuretic, BB), antidiabetic, antihyperlipidemia, antiplatelet, antiangina, analgesic-antipyretic, corticosteroid, respiratory system drugs, digestive system, endocrine system, respiratory system drugs, blood disorders, antihistamine, anti-pirai, antibiotic, vitamin and mineral.
