The uptake of medicated water is dependant on the clinical condition of animals. In order to obtain the correct dosage, the concentration in drinking water may have to be adjusted.

Underdosing can lead to ineffective use and promote the development of resistance.

The dosage should be based on the current, actual drinking water intake of the animals, because this varies depending on the animal species, on the age, state of health and intended use of the animals and depending on the housing conditions (e.g. temperature, lighting regime)

Thus, to achieve the correct dose, appropriate adjustment of the toltrazuril concentration may be necessary. The use of properly calibrated measuring equipment is recommended.

Meat and offal:

Chickens: 16 days.
Turkey poults: 16 days.

Special warnings for each target species

Colistin exerts concentration-dependent activity against Gram-negative bacteria. Following oral administration high concentrations are achieved in the gastrointestinal tract, i.e. the target site, due to the poor absorption of the substance. These factors indicate that a longer duration of treatment than the one indicated, leading to unnecessary exposure, is not recommended.

Special precautions for use

Special precautions for use in animals

Do not use colistin as a substitute for good management practices. Colistin is a last resort drug in human medicine for treatment of infections caused by certain multi-drug resistant bacteria. In order to minimise any potential risk associated with widespread use of colistin, its use should be limited to treatment or treatment and metaphylaxis of diseases, and should not be used for prophylaxis. Whenever possible, colistin should only be used based on susceptibility testing. Use of the product deviating from the instructions given may lead to treatment failures and increase the prevalence of bacteria resistant to colistin.

Special precautions to be taken by the person administering the medicinal product to animals

People with known hypersensitivity to any of the product ingredients should avoid contact with the veterinary medicinal product. To prevent any unpleasant effects, personal protective equipment consisting in rubber gloves, goggles and protective masks should be worn when administering the product. In case of accidental ingestion or the occurrence of symptoms characterized by skin rash, seek medical advice. Serious symptoms such as swelling of face, lips or eye lids, accompanied by breath difficulties, need immediate medical attention.

Use during pregnancy, lactation or lay

Following the studies made on laboratory animals, colistin sulphate, administered orally, due to low absorption from digestive tract, has not impaired the reproductive functions nor offsprings evolutions the product can be used safely.

Interactions with other medicinal products

Colistin has synergism with beta-lactams and bacteriostatic antibiotics (tetracyclines, macrolides).

Incompatibilities

Being an oral veterinary medicinal product that is not absorbed from the gastrointestinal tract, the administration with other medicinal products for oral use containing divalent metal ions (e.g. calcium, iron or magnesium). will be avoided.

Incompatibility with ampicilin.

For the environmental protection, medicines should not be disposed of via wastewater or household waste. Any unused veterinary medicinal product or waste materials derived from such veterinary medicinal products should be disposed of in accordance with local requirements.
