Which of the following is an adverse reaction of carbamazepine?

• A. Rash
• B. Nausea
• C. Fatigue
• D. Dizziness

Answer: (A)

Carbamazepine is known for causing skin-related hypersensitivity reactions, and a rash is a classic adverse effect to watch for. This type of reaction can range from mild eruptions to serious conditions such as Stevens-Johnson syndrome, which makes it a critical safety signal that may require stopping the medication and urgent medical assessment. While nausea, fatigue, and dizziness can occur with carbamazepine as well, they are general, non-specific side effects related to the drug’s effects on the GI tract or CNS. The rash stands out because of its potential severity and the action it necessitates—discontinuing the drug and evaluating for possible progression. If a rash develops, seek prompt medical guidance to ensure patient safety.
