Clinical information

Flimabo 100 mg/g Suspension for Use in Drinking Water for Chickens and Pigs — SPC Details

Source: VMD Summary of Product Characteristics (SPC). Last updated 27 Mar 2026.

In pigs:
Treatment of helminthiasis caused by (adult and intestinal larval stages) in
piglets, pigs for fattening, pregnant and lactating sows.
Hens/chickens:
1.43 mg flubendazole (= 14.3 mg veterinary medicinal product) per kg body weight daily
during 7 days i.e. 1 g of the veterinary medicinal product per 70 kg body weight daily for 7
days.
Pigs:
a) Treatment of helminthiasis caused by (adult stages and intestinal
larval stages):
1 mg flubendazole (= 10 mg veterinary medicinal product) per kg body weight daily
during 5 days, i.e. 1 g of the veterinary medicinal product per 100 kg body weight daily
for 5 days;
b) Treatment of helminthiasis caused by (adult stages):
2.5 mg flubendazole (= 25 mg veterinary medicinal product) per kg body weight daily
during 2 days, i.e. 2.5 g of the veterinary medicinal product per 100 kg body weight
daily for 2 days.
Pigs should be grouped according to their bodyweight and dosed accordingly, in order to
prevent under or overdosing.
Based on the recommended dose and the number and weight of animals to be treated,
the exact daily concentration of the veterinary medicinal product should be calculated
according to the following formula:
mg veterinary medicinal
product/kg body
weight/day
Xaverage body weight
(kg) of animals to be
treated
average quantity of drinking water (l/animal)
consumed in 4 h=mg veterinary medicinal
product per litre of drinking
water
This will result in a concentration of flubendazole between 20 and 200 mg per litre.
Method of administration:
Administration in drinking water

estimated body weight of the total group animals (see table below for guidance).

2) Each day a predilution is prepared containing the daily required dose of the
veterinary medicinal product admixed in 10 to 100 times its weight in water
depending on the distribution system. For example: for 500 g of the veterinary
medicinal product, add 5 litres to 50 litres of water.
3) If less than entire package (a sachet or a container) is required, the required dose
should be measured by suitably calibrated weighing equipment.
4) If the entire sachet is used, squeeze it gently before use and then empty the
contents into the predilution recipient.
5) Stir the predilution vigorously with a manual mixer (whisk) for 2 minutes to obtain a
white milky homogenous mixture.
6) This predilution must be distributed via the general water supply system:
Tanks: add the predilution to the quantity of water usually consumed by the animals
over a period of up to 4 hours.
Dosing pumps: adjust the flow rate of the pump to distribute the predilution over a
period of up to 4 hours.
In order to ensure administration of the correct dose, a substantial water flow must
be present in the drinking water system. Administration of the veterinary medicinal
product over a period of up to 4 hours on each treatment day, at times when water
consumption is likely to be highest prevents precipitation of flubendazole in the
water delivery system and allows washing out of the drinking water system within a
24 hour period after the period of drug administration is finished.
7) Prior to and after the period of treatment make sure the water distribution system is
cleaned.
8) Make sure that all animals in the group receive enough drinking water with the
veterinary medicinal product. Withhold drinking water for 2 hours before treatment
to stimulate thirst.
9) The corresponding dose must always be distributed when the water consumption of
the animals is highest.
Do not use in cases of hypersensitivity to the active substance or to any of the excipients.
Pigs:
None known.
Chickens:
Undetermined frequency

Reporting adverse events is important. It allows continuous safety monitoring of a
veterinary medicinal product. Reports should be sent, preferably via a veterinarian, to
either the marketing authorisation holder <or its local representative> or the national
competent authority via the national reporting system. See the package leaflet for
respective contact details.
In chickens, optimal results can only be achieved if strict rules of hygiene are respected
in the maintenance of the cages.
In both species:
Care should be taken to avoid the following practices because they increase the risk of
development of resistance and could ultimately result in ineffective therapy:
• Too frequent and repeated use of anthelmintics from the same class, over an extended
period of time.
• Underdosing, which may be due to underestimation of body weight, misadministration
of the veterinary medicinal product, or lack of calibration of the dosing device (if any).
Suspected clinical cases of resistance to anthelmintics should be further investigated
using appropriate tests (e.g. Faecal Egg Count Reduction Test). Where the results of the
test(s) strongly suggest resistance to a particular anthelmintic, an anthelmintic belonging
to another pharmacological class and having a different mode of action should be used.
