There are various Panacur AquaSol medicants available on Amazon, for cats, dogs & rabbits but no mention of chickens.
Panacur AquaSol is a medicine that contains the active substance fenbendazole. It is available as an oral suspension (200 mg/ml) for use in drinking water for pigs and chickens.
Panacur AquaSol is used for the treatment and control of three types of roundworm infections in the gut of pigs:
Ascaris suum (adult and intestinal and migrating larval stages);
Oesophagostomum worms (adult stages);
Trichuris suis (adult stages).
Panacur AquaSol is also used for the treatment of two types of roundworm infections in the gut of chickens:
Ascaridia galli (L5 and adult stages);
Heterakis gallinarum (L5 and adult stages).
For pigs, Panacur AquaSol is added to their drinking water in a quantity that aims to supply each pig 2.5 mg fenbendazole per kg bodyweight daily; this is done for two consecutive days for treatment and control of Ascaris suum and Oesophagostomum infections, and for three consecutive days to treat and control Trichuris suis. The amount added is based on the combined weight of all the pigs to be treated, with 2.5 mg added for each kg bodyweight on each treatment day (two or three consecutive days respectively).
For chickens, Panacur AquaSol is added to their drinking water in a quantity that aims to supply each chicken 1 mg fenbendazole per kg bodyweight daily; this is done for five consecutive days.
Before allowing the animals to access the medicated water the water delivery system should be drained and flushed with the medicated water.
There are currently no known side effects associated with Panacur AquaSol. Repeated use of Panacur AquaSol or a similar anthelmintic may result in resistance. The medicine should not be allowed to enter surface waters as it has harmful effects on aquatic organisms.
