Recommended treatment scheme: reduction of vomiting is achieved in about 2 weeks. Animals should however be treated for at least 2 weeks after the remission of clinical signs, so a minimum treatment duration of 28 days is usually necessary and therefore recommended. If considered successful, medication should be withdrawn for 2 weeks. If vomiting occurs again, treatment can be re-initiated without risk of intolerance.
Depending on the response, treatment can be adapted to the individual animal until the response is considered to be adequate and continued. Dietary measures should always be maintained.
Adverse reactions
Transient and self-resolving slight swelling of mammary glands may be observed in female dogs (gynaecomastia; anti-androgenic activity). A reduction of prostate weight was also observed in male rats and dogs, with no impact on reproductive performances; this effect was reversible. No other undesirable effects were reported.
