Rifabutin toxicity is unusual at doses of 300 mg daily or less. Uveitis associated with rifabutin and macrolide therapy for Mycobacterium avium intracellulare infection in AIDS patients. Introduction Disodium Pamidronate, a Calcium regulating agent, was described by Macarol and Frauenfelder [1] and other authors [2-5] to induce ocular inflammation. Our findings support the observation that prophylactic doses of rifabutin, combined with clarithromycin, fluconazole or other agents which can increase rifabutin levels, can induce uveitis in patients with AIDS. OBJECTIVE: Uveitis has been increasingly recognised as a side effect of rifabutin regimens in the prophylaxis and treatment of Mycobacterium avium intracellulare (MAI) infection. R ifabutin is prescribed for the treatment and prophylaxis of Mycobacterium avium complex (MAC) infection in HIV-positive patients. However, clarithromycin and/or fluconazole can raise rifabutin levels (and consequently the risk for uveitis) due to shared hepatic metabolism by the same cytochrome P450 system. Rifabutin is prescribed frequently for the prophylaxis and treatment of MAC infection, especially in patients with HIV. A comparison of two regimens for the treatment of Mycobacterium avium complex bacteremia in AIDS: rifabutin, ethambutol, and clarithromycin versus rifampin, ethambutol, clofazimine, and ciprofloxacin.

To review rifabutin-associated uveitis and discuss the mechanism and potential role of drug interactions with clarithromycin and fluconazole in contributing to this adverse event. Only systemically administered biphosphonates and, perhaps, topical metipranolol meet all seven criteria.

Most authors have commented on the increased risk of rifabutin-induced uveitis in cases of concomitant treatment with clarithromycin. More recent reports noting the association of uveitis with these lower dosages of rifabutin have raised concerns about the prevalence of this adverse event. An early suspicion of rifabutin induced uveitis could also prevent invasive ocular procedures like aqueous sampling and a detailed drug history should be elicited in unexplained uveitis [15]. Rifabutin has been associated not only with a characteristic hypopyon anterior uveitis, but also with other forms of uveitis such as intermediate uveitis, panuveitis, and retinal vasculitis, which have been recently reported.
