Dechra Veterinary Products has announced a new solution for the mass treatment of respiratory disease in pigs and chickens.

MetaxolMetaxol, part of the firm’s SoluStab range, is replacing Methoxasol and is aimed at farmers wanting to target entire flocks thanks to its shorter withdrawal time for broilers.

Metaxol contains 20mg trimethoprim and 100mg sulfamethoxazole per ml, and can be added directly to drinking water or used in a concentrated stock.


In fattening pigs, it is suitable for the treatment and metaphylaxis of post-weaning diarrhoea caused by beta-haemolytic K88-positive, K99-positive or 987P Escherichia coli strains susceptible to trimethoprim-sulfamethoxazole.

It can also be used for secondary bacterial infections caused by Pasteurella multocida, Actinobacillus pleuropneumoniae, Streptococcus species and Haemophilus parasuis susceptible to trimethoprim-sulfamethoxazole.


In broilers, it can be used for treatment and metaphylaxis of colibacillosis caused by E coli susceptible to trimethoprim-sulfamethoxazole, and coryza caused by Avibacterium paragallinarum.


The recommended dosage is:

  • Pigs – 0.25ml of product per kg bodyweight per day for four to seven days for pigs.
  • Chickens – 0.38ml of product per kg bodyweight per day for three days.

Metaxol is not suitable for laying hens.
