Side effects

In cats, typical side effects of NSAIDs such as loss of appetite, vomiting, diarrhoea, faecal occult blood, apathy and renal failure have been reported occasionally. Elevated liver enzymes have been reported in very rare cases. These side effects are in most cases transient and disappear after discontinuation of treatment, but in very rare cases can be serious or fatal. If side effects occur, treatment should be discontinued.

The frequency of side effects is defined as follows:

  • Very common (more than 1 in 10 animals treated show side effect(s))
  • Common (more than 1 but less than 10 animals in 100 animals treated)
  • Uncommon (more than 1 but less than 10 animals in 1,000 animals treated)
  • Rare (more than 1 but less than 10 animals in 10,000 animals treated)
  • Very rare (less than 1 in 10,000 animals treated, including isolated reports)
