Corneal deposits and retinal disturbances, including those of the macula , have been observed in some patients who had received prolonged therapy with INDOCIN. Be alert to the possible association between the changes noted and INDOCIN. It is advisable to discontinue therapy if such changes are observed. Blurred vision may be a significant symptom and warrants a thorough ophthalmological examination. Since these changes may be asymptomatic , ophthalmologic examination at periodic intervals is desirable in patients receiving prolonged therapy. INDOCIN is not indicated for long-term treatment.

Potential adverse effects of chronic corticosteroid therapy should be weighed against the clinical benefits obtained and the availability of other treatment alternatives. Prolonged systemic corticosteroid therapy can lead to osteoporosis, vertebral compression fractures, aseptic necrosis of femoral and humoral heads, and pathologic fractures of long bones secondary to decreased bone formation, increased bone resorption, and protein catabolism in any patients. A high-protein diet may alleviate or prevent the adverse effects associated with protein catabolism. The elderly, post-menopausal, and pediatric patients may be more susceptible to the effects on bone. Chronic systemic triamcinolone therapy may cause growth inhibition in pediatric patients due to hypothalamic-pituitary-adrenal axis suppression and inhibition of bone growth. Corticosteroids should be titrated to the lowest effective dose. Because bone development is critical in pediatric patients, monitoring is warranted in patients receiving high-dose or chronic corticosteroid treatment. Growth inhibition may also occur with intranasal or topical triamcinolone due to systemic absorption, particularly in susceptible patients or when used in high doses or for prolonged periods of time. Use of the lowest effective dose is recommended to minimize the occurrence of systemic adverse effects. Monitor growth routinely.

The potassium-sparing diuretics are competitive antagonists that either compete with aldosterone for intracellular cytoplasmic receptor sites, or directly block sodium channels (specifically epithelial sodium channels (ENaC) by amiloride ). The former prevents the production of proteins that are normally synthesized in reaction to aldosterone. These mediator proteins are not produced, and so stimulation of sodium-potassium exchange sites in the collection tubule does not occur. This prevents sodium re-absorption and potassium and hydrogen ion secretion. [3]
