Case Study of Stomatitis Medicamentosa Due to Trigeminal Neuralgia Medication

Abstract

Our study aim is to characterize and assess the case of Stomatitis medicamentosa in a patient who developed manyoral ulcers after using Carbamazepine for the treatment of Trigeminal Neuralgia of a 35-year-old female patient with a medicalhistory of hypertension for the past ten years and under medication. The patient also gave a history of electric shock-like painon the left side of the face for the past month and was prescribed Tegretol 100mg (Carbamazepine) twice daily. After taking thismedication, the patient suffered several mouth ulcers. The patient was asked to stop taking this medication and asked to takeoral antihistamines and systemic Gabapentin steroids for one month. After one week, the patient heals completely from thelesions. Burning sensation with altered taste sensation and difficulty while swallowing are common patient complaints. Mouthopening was restricted and painful. The skin test (prick test) is done, which shows red, papular, or vesicular reactions. Earlyidentification of the lesion and prompt withdrawal of the offending drug are key for successful management, and the drug can bereplaced with another drug of the same efficacy. Thus, adverse drug reactions can be minimised by asking the patient aboutallergy to any drug or food while writing a prescription, and the patient should be informed and familiarised with the drugpatient the patient is allergic.
