|---|---|---|
| Exanthems | Delayed-type hypersensitivity Evolve over days after drug initiation Diffuse macules and papules |
Aminopenicillins, antibacterial sulfonamides, cephalosporins, allopurinol, antiepileptic agents |
| Urticaria/ angioedema | Often IgE mediated Onset within minutes of drug initiation |
β-lactam antibiotics, ACE-Is |
| Fixed drug eruption | Hyperpigmented plaques that recur at same skin or mucosal site | NSAIDs, tetracyline, carbamezapine |
| Pustules | Acneiform Acute generalized eczematous pustulosis (AGEP) |
Acneiform: corticosteroids, sirolimus AGEP: antibiotics, calcium-channel blockers |
| Bullous | Tense blisters Flaccid blisters |

| SJS | Fever, erosive stomatitis, ocular involvement, purpuric macules on face and trunk with <10% epidermal detachment | Antibacterial sulfonamides, anticonvulsants, oxicam NSAIDs, and allopurinol |
| TEN | Similar features as SJS but >30% epidermal detachment Mortality as high as 50% |
Same as SJS |

| Multiorgan Reactions | Clnical Features | Implicated Medications |
|---|---|---|
| Anaphylaxis | Urticaria, angioedema, bronchospasm, gastrointestinal symptoms, hypotension IgE- and non–IgE-dependent reactions |
β-lactam antibiotics, mAbs |
| DRESS | Cutaneous eruption, fever, eosinophilia, hepatic dysfunction, lymphadenopathy | Anticonvulsants, sulfonamides, minocycline, allopurinol |
| Serum Sickness | Arthralgias, myalgias, fever, malaise | Hydralazine, procainamide, isoniazid |
