Both toxins and allergic reactions to drugs have been linked to myocarditis. Specifically, exposure to alcohol, radiation, and chemicals, such as hydrocarbons and arsenic, have been implicated. Damage caused by the anti-cancer drug doxorubicin has also been associated with causing myocarditis. Severe allergic reactions to antibiotics have also been linked to myocarditis, including sulphonamides and penicillin.
