Cases of dysgeusia or ageusia have been reported in patients treated with angiotensin II receptor antagonist such as losartan (5 cases), valsartan (1 case), eprosartan (1 case). This is the first case-report of ageusia following candesartan. A 46-year-old-male patient, with a medical history of renal chronic reject allograft disease, started candesartan 4 mg once daily to treat high blood pressure. Six months later, a progressive ageusia occurred with a burning mouth syndrome. He also developed aphthous ulcers of the mouth, stomatitis and perleche, which led him to lose 8 kilos within 13 months. Thirteen months after the beginning of the treatment candesartan was stopped. The symptoms and lesions required 2 to 3 weeks to disappear. Subsequently, appetite was found again as well as the sense of taste. The temporal sequence of events suggests a causal relationship between ageusia and candesartan.
