Amantadine and Rimantadine (RX) for treatment of Flu in Children with Flu

  • Mixed

    Bottom Line

  • Treatment of Influenza A with Amantadine and Rimantadine. 3 studies conducted, with 382 children. Reduces the fever on the 3rd day of treatment for 1 in 6 treated children, and ineffective for other symptoms. Unknown impact on complications. Both drugs have irritating stomach and gut effects, while Amantadine may also impair the nervous system and lead to psychiatric symptoms.



Avoid this treatment:

Proven benefits include only reduced fever, while side effects are often irritating for both treatments, and are pretty dangerous for Amantadine. Consider Neuraminidase inhibitors instead (they are as effective, but safer).
