Acetazolamide (commonly used in the treatment of glaucoma): Long-term use may lead to hypokalemia and acidosis, and decreased citrate excretion in the urine, resulting in kidney stones due to precipitation of calcium phosphate crystals. Vitamin D: Excess vitamin D may lead to calcium buildup in various parts of the body. The daily intake of vitamin D should preferably not exceed 400 IU. Vitamin C: If you are prone to the formation of calcium oxalate stones, the amount of vitamin C should be limited. More than 3 grams to 4 grams a day may increase the production of oxalic acid, thus increasing the chances of stone formation. Do not consume high potency vitamin c supplements. Glucocorticoids: Glucocorticoids have the effect of mildly inhibiting bone mass and reducing the reabsorption of calcium and phosphorus by the renal tubules while increasing their excretion. Long-term use of glucocorticoids can increase urinary calcium and phosphorus excretion, producing hyperuricemia and triggering renal calcification and kidney stones. Sulfonamides: Long-term use of sulfonamides is most likely to form crystals of sulfadiazine, which can also cause kidney stones. Aspirin: Aspirin also has the effect of increasing urinary oxalic acid, and long-term use can increase the probability of oxalic acid stones.
