Treatment
Treatment Options Benznidazole and nifurtimox are the drugs available for treatment. [dermatologyadvisor.com]

There is no treatment that will cure a viral infection. However, for most people with viral myocarditis, the virus clears away on its own without any treatment, often within a week or so. [patient.info]
