Epidural steroid therapy for herpes zoster associated pain is known to be effective with rare complications. However, certain amount of epidurally-injected steroid may be absorbed and affect endocrinological system. Specially, triamcinolone acetonide has high affinity for progesterone receptors and may influence mensturation. We report a case of a postmenopausal women treated with 40 mg of epidural triamcinolone acetonide twice with a two week interval and followed a large amount of uterine bleeding.
