In some patients, significant calcium deficiency leading to hypocalcemia can present with acute respiratory manifestations such as laryngospasm and bronchospasm, often in the context of generalized neuromuscular irritability and tetany. Case reports describe episodes of stridor, tightness in the chest, and even acute respiratory distress that improve as ionized calcium levels are corrected. The key clinical implication is that, when otherwise unexplained laryngospasm or bronchospasm occurs alongside perioral numbness, carpopedal spasm, or muscle cramps, prompt evaluation and correction of calcium deficiency can be lifesaving and help prevent recurrent respiratory compromise. This medication is commonly used for Pain Management.

Some side effects may be linked to nutrient depletion caused by this medication.
Indomethacin, a medication commonly used to treat inflammation and pain, can decrease the absorption of vitamin C. Vitamin C plays a vital role in immune function and the body's antioxidant defenses. To counteract this effect and maintain a healthy immune system and antioxidant capacity, vitamin C supplementation is recommended for individuals taking Indomethacin.
Studies suggest that indomethacin, a type of nonsteroidal anti-inflammatory drug (NSAID), might decrease calcium levels in the body. To prevent potential calcium deficiency, supplementation should be considered for individuals taking indomethacin on a long-term basis.
