Severe skin adverse drug reactions can result in death, but the rate of such events is fortunately low. The incidences of Stevens-Johnson syndrome and toxic epidermal necrolysis range from 1.2 to 6 per million per year and 0.4 to 1.2 per million per year, respectively. Stevens-Johnson syndrome is fatal in about 5% and toxic epidermal necrolysis in 30% of cases. Drugs implicated in these diseases are the sulphonamides, anticonvulsants, allopurinol, pyrazolone derivatives, oxicams and chlormezanone. The principles of symptomatic treatment are the same as for burns, and patients with extensive skin detachment should be transferred to an intensive care unit or a burn centre. Hypersensitivity syndrome is characterised by mucocutaneous eruption and fever with frequent lymphadenopathy, hepatitis and eosinophilia. Drugs implicated are mainly anticonvulsants and sulphonamides. The mortality rate of such a reaction has been estimated to be about 8%. Corticosteroid therapy has been widely used in hypersensitivity syndrome, despite the lack of controlled studies. Drug-induced vasculitis and serum sickness may also be life-threatening when the kidney, liver, gastrointestinal tract or nervous system are involved. In angioedema, congestion may involve mucous membranes and therefore impair swallowing and ventilation. Drugs associated with angioedema include penicillins, radiographic contrast agents and ACE inhibitors. Severe forms of angioedema necessitate epinephrine (adrenaline) subcutaneous injection and possibly resuscitative efforts. Corticosteroids and/or antihistamines are used to block or reduce prolonged or late phase reactions. Prompt recognition and withdrawal of the suspected drug is essential in severe drug-induced skin reactions.

SARS-CoV-2 is a novel coronavirus that emerged in 2019 and is causing the COVID-19 pandemic. There is no current standard of care. Clinicians need to be mindful of the toxicity of a wide variety of possibly unfamiliar substances being tested or repurposed to treat COVID-19. The United States Food and Drug Administration (FDA) has provided emergency authorization for the use of chloroquine and hydroxychloroquine. These two medications may precipitate ventricular dysrhythmias, necessitating cardiac and electrolyte monitoring, and in severe cases, treatment with epinephrine and high-doses of diazepam. Recombinant protein therapeutics may cause serum sickness or immune complex deposition. Nucleic acid vaccines may introduce mutations into the human genome. ACE inhibitors and ibuprofen have been suggested to exacerbate the pathogenesis of COVID-19. Here, we review the use, mechanism of action, and toxicity of proposed COVID-19 therapeutics.
