Aivlosin: Veterinary drug
Aivlosin is an antibiotic and is available as a premix for medicated feeding stuff and as an oral powder for pigs,
and as granules for use in drinking water for pigs, chickens and pheasants.
The premix is mixed into pig feed by an authorised feed mill and the resulting “medicated
feeding stuff” is then distributed to the farmer to treat a large number of pigs. The oral powder
is mixed into pig feed by the pig owner and is used to treat individual pigs. The granules are
added to the drinking water system, either directly or after dilution into a stock solution.
In pigs, it is used to treat or prevent a number of infectious diseases that are caused by bacteria
that affect the lungs (i.e. Swine Enzootic Pneumonia) or the intestinal tract (Swine Dysentery
or Porcine Proliferative Enteropathy). Aivlosin improves the health and weight of the animals,
but may not eliminate completely the bacteria that caused lung infection.
In chickens and pheasants, it is used for lung infections caused by a bacterium Mycoplasma
The studies showed that pigs treated with Aivlosin lost less weight during the infection and
showed less severe signs of disease than untreated animals. The treatment success with
Aivlosin was similar to the effectiveness of other medicines of the same class authorised for
such diseases in pigs.
Chickens and pheasants treated with Aivlosin showed less severe signs of disease than
untreated animals. The effectiveness of Aivlosin was similar to that of other medicine of the
same class already authorised for this disease in chickens. The treatment did not completely
eliminate all bacteria in the respiratory system and some birds still showed the disease;
however, the number of affected animals was significantly smaller than in an untreated group
AIVLOSIN SIDE EFFECTS
Very ill pigs might not eat all the feed offered and therefore might get an insufficient amount
of the medicine. Therefore, treatment via feed with Aivlosin is not recommended for these
Since the composition of the pig feed might affect the effectiveness of Aivlosin, it should only
be used in dry feed. The oral powder cannot properly be mixed into pellets and should
therefore not be used in pelleted pig feed.
The medicated drinking water should be replaced every 24 hours.
AIVLOSIN: PRECAUTIONS FOR HUMANS
Aivlosin might cause skin reactions in some people. People who had in the past skin reactions
when handling Aivlosin or similar products, should avoid any contact with Aivlosin.
When mixing Aivlosin into feed or drinking water or handling the medicated feed or water,
direct contact with eyes, skin and mouth should be avoided and protective equipment should
be worn, e.g. overalls, gloves and face masks (respirator). Skin that has been in contact with
Aivlosin or medicated feed or drinking water should be washed.
Aivlosin should not be used in people. However, if Aivlosin is accidentally consumed by a
person, the advice of a doctor should be sought immediately.
AIVLOSIN: WITHDRAWAL PERIOD
After the last administration of Aivlosin in the feed (pigs) or via drinking water (chickens and
pheasants), animals should not be slaughtered for two days. Aivlosin should not be used in
birds that lay eggs for human consumption. It should, therefore, not be used in laying birds or
in the two weeks before hens are likely to start laying eggs for human consumption.
After administration of Aivlosin via drinking water, pigs should not be slaughtered for one
