2 cited drugs treat Giardiasis in guinea pigs: Fenbendazole, Metronidazole.
Intestinal infection with Giardia (a flagellate protozoan). Common in young or recently rehomed animals and across exotic species kept in groups; presents as soft to watery diarrhoea, often intermittent. Treatment options vary by species — some species tolerate metronidazole poorly.
