Valganciclovir

Valganciclovir (Valcyte) is an antiviral used to treat cytomegalovirus infections. It is active against a number of herpesviruses.

Chronic Fatigue Syndrome
Valcyte is used off-label to treat patients with ME/CFS. Studies have shown mixed evidence of efficacy.

Valcyte may improve systems by via it's broad spectrum antiviral activity against latent herpesviruses, which may reactivate in immunocompromised patients, including ME/CFS patients.

It may also have direct anti-inflammatory effects. ME/CFS patients have been shown to have chronic activation of microglia and Valcyte inhibits microglia proliferation and activation.
