Anticonvulsant/sulfonamide hypersensitivity syndrome is a potentially serious hypersensitivity reaction that can be seen with medications with an aromatic amine chemical structure, such as aromatic anticonvulsants, sulfonamides, or other medications with an aromatic amine. Cross-reactivity should not occur between medications with an aromatic amine and medications without an aromatic amine ; therefore, these medications can be safely used in the future.
