Indomethacin & Vitamin C

Depletes Vitamin C. This medication is commonly used for Pain Management

Why Indomethacin affects Vitamin C

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.

Related Health Impacts

  • Eye Bleeding & Vision Issues

    Vitamin C deficiency weakens collagen in capillary and vascular walls, so severe scurvy can present with ocular hemorrhages in the conjunctiva and retina that threaten vision if not treated. Case reports and small series describe retinal hemorrhages, flame‑shaped hemorrhages, and even retrobulbar bleeding compressing the optic nerve, which can lead to optic neuropathy and visual loss in advanced cases. The encouraging point is that, when vitamin C deficiency is recognized early and promptly repleted, many ocular hemorrhages and visual symptoms can partially or fully resolve, making it critical to consider vitamin C status in patients with otherwise unexplained ocular bleeding and visual complaints.

  • Lung & Breathing Problems

    When vitamin C runs low, its impact isn’t just skin‑deep, it can also affect the heart and lungs, sometimes contributing to shortness of breath, fatigue, and fluid retention. Severe vitamin C deficiency has been reported as a reversible cause of pulmonary hypertension and right‑sided heart failure, with pressures in the lung circulation and cardiac strain improving after vitamin C is replaced. Broader cardiovascular research also links low vitamin C with higher blood pressure and stiffer arteries, while short‑term supplementation in some hypertensive or diabetic patients has lowered systolic blood pressure and improved arterial stiffness, suggesting that adequate vitamin C helps support healthier vascular tone and cardiac workload.

  • Weakened Immune System

    Even a modest shortfall in vitamin C can leave the immune system less resilient, showing up as more frequent colds, flus, or lingering infections that are slow to clear. Vitamin C concentrates to very high levels inside neutrophils, where it helps fuel their oxidative burst, regulate antioxidant enzymes, and support normal cell survival, so low vitamin C can mean these “first‑responder” white blood cells do not work at full strength. Clinical trials are mixed but intriguing: in a substantial subset of studies, vitamin C supplementation improved neutrophil functions such as oxidative burst, antioxidant enzyme activity, and even reduced premature neutrophil cell death in very sick patients, suggesting that correcting low vitamin C may help the body respond more effectively when infections strike.
