Carbamazepine (CBZ) is widely used for the treatment of trigeminal neuralgia (TN), however, it is associated with some side effects. A 61-year-old woman was given CBZ to relieve TN pain. The pain was relieved immediately, but on the third day of CBZ treatment, skin rash developed, and the drug was discontinued. She then received the Kampo (Japanese herbal) medical formula Keishi-ka-jutsubu-to according to the principles of Kampo diagnosis. The pain was completely controlled without any side effects.
For maximum effectiveness, Kampo formulas should always be selected through the Kampo diagnostic process.
