| Type of Infection | First Line (with Dosage and Duration) |
Alternative First Line (with dosage and Duration) |
Comments |
|---|---|---|---|
| Uncomplicated | No empirical antibiotics required | Mild myocarditis may only need rest and supportive medicine. If myocarditis is severe, immunomodulators like steroids may be administered to improve cardiac function. Myocarditis is a diagnosis of exclusion. If bacterial cause is ascertained through culture, start antibiotics based on AST results. | |
| No empirical antibiotics required | If myocarditis is causing severe heart failure or arrythmia, to reduce the risk of blood clots anticoagulants may be administered. In addition, to address fluid overload and to reduce the strain on the heart, diuretics, beta blockers, angiotensin- converting enzyme (ACE) inhibitors or angiotensin 2 receptor blockers (ARBs) need to be given. |
