Zoetis Linco Spectin 100 (150 g)

Indications for use, specifying the target species

Pigs

For the treatment and metaphylaxis of porcine proliferative enteropathy (ileitis) 

caused by Lawsonia intracellularis, and associated enteric pathogens (Escherichia 

coli) susceptible to lincomycin and spectinomycin. 

The presence of the disease in the group must be established before the product is used.

Chickens

For the treatment and metaphylaxis of chronic respiratory disease (CRD) caused by 

Mycoplasma gallisepticum and Escherichia coli susceptible to lincomycin and 

spectinomycin and associated with a low mortality rate.

The presence of the disease in the flock must be established before the product is 

used.

Contraindications

Do not use in case of hypersensitivity to the active substances or any of the 

excipients. 

Do not use in case of hepatic dysfunction.

Do not allow rabbits, rodents (e.g. chinchillas, hamsters, guinea pigs), horses or 

ruminants to access to water or feeds containing lincomycin. Ingestion by these 

species may result in severe gastrointestinal effects.

Do not use in laying hens.

Special warnings for each target species

In E. coli, a significant part of the strains shows high MIC values (minimum inhibitory 

concentrations) against the lincomycin-spectinomycin combination and may be 

clinically resistant, although no breakpoint is defined.

Due to technical constraints the susceptibility of L. intracellularis is difficult to test in 

vitro, and data about the lincomycin-spectinomycin resistance status in that species are lacking.

Special precautions for use

Special precautions for use in animals

It is sound clinical practice to base treatment on susceptibility testing of the bacteria 

isolated from the animal. If this is not possible, therapy should be based on local 

(regional, farm level) epidemiological information about susceptibility of target bacteria.

Use of the veterinary medicinal product deviating from the instructions in the SPC 

may increase the risk of development and selection of resistant bacteria and decrease the effectiveness of treatment with macrolides due to the potential for 

cross-resistance.

The oral use of preparations containing lincomycin is only indicated in swine and chickens. 

Do not leave access to the medicated water for other animals. 

Lincomycin may lead to severe gastrointestinal disturbances in other animal species. 

The repeated or prolonged use should be avoided, by improving the farm management and disinfection practices. 

Diagnosis should be reconsidered if improvement is not seen after 5 days. 

Sick animals have a reduced appetite and an altered drinking pattern, and severely 

affected animals may therefore require parenteral treatment. 

This powder is for use in drinking water only and should be dissolved before use. 

Withdrawal period(s)

Pigs:

Meat and offal: Zero days.

Chickens:

Meat and offal: 5 days.

Not for use in birds producing or intended to produce eggs for human consumption.

Animals must not be slaughtered for human consumption during treatment.
