Cross-reactivity should not occur between drugs with an aromatic amine and drugs without an aromatic amine (e.g., sulfonylureas, thiazide diuretics, furosemide, and acetazolamide); therefore, these drugs can be safely used in the future.[1] The hypersensitivity syndrome is characterized by a skin eruption that is initially morbilliform.[2]{{rp|118}} The rash may also be a one of the potentially lethal severe cutaneous adverse reactions, the DRESS syndrome, Stevens-Johnson syndrome, or toxic epidermal necrolysis.[3][4] Systemic manifestations occur at the time of skin manifestations and include eosinophilia, hepatitis, and interstitial nephritis. However, a subgroup of patients may become hypothyroid as part of an autoimmune thyroiditis up to 2 months after the initiation of symptoms.[1] This kind of adverse drug reaction is caused by the accumulation of toxic metabolites; it is not the result of an IgE-mediated reaction. The risk of first-degree relatives’ developing the same hypersensitivity reaction is higher than in the general population.[1] As this syndrome can present secondary to multiple anticonvulsants, the general term "anticonvulsant hypersensitivity syndrome" (AHS) is favored over the original descriptive term "dilantin hypersensitivity syndrome."[2]{{rp|118}} As of 2015, two cases of AHS have been reported that manifested during long-term treatment with multiple anti-seizure medications. Death due to multiple organ failure can occur; symptoms also mimic lymphoma, AHS has been called "pseudolymphoma" as a result. Changing the medications involved to those in a different class can avoid further problems.[5] See also
