Parenteral calcium can neutralize the effects of hypermagnesemia or magnesium toxicity secondary to parenteral magnesium sulfate
Patients on digitalis therapy are more apt to develop arrhythmias if receiving IV calcium—use with caution
With oral calcium may lead to increased serum magnesium and/or calcium, particularly in patients with renal failure.
Patients receiving both parenteral calcium and potassium supplementation may have an increased chance of developing cardiac arrhythmias—use cautiously
Oral calcium can reduce the amount of tetracyclines or fluoroquinolones absorbed from the GI tract; separate dosages by two hours if possible
Concurrent use of large doses of vitamin D or its analogs may cause enhanced calcium absorption and induce hypercalcemia
Intravenous calcium may antagonize the effects of calcium-channel blocking agents

Parenteral calcium may reverse the effects of nondepolarizing neuromuscular blocking agents; calcium has been reported to prolong or enhance the ef...
Thiazide Diuretics✅ 低風險
Used in conjunction with large doses of calcium may cause hypercalcemia
Excessive intake of vitamin A may stimulate calcium loss from bone and cause hypercalcemia.
