Contra-indications, warnings, etc
Do not use in horses with known hypersensitivity to pergolide mesylate or other ergot derivatives or to any of the excipients.
Do not use in horses less than 2 years of age.
Appropriate endocrinologic laboratory tests should be conducted as well as evaluation of clinical signs in order to establish a diagnosis of PPID.
Special precautions for use in animals
As the majority of cases of PPID are diagnosed in aged horses, other pathological processes are frequently present.
In rare cases inappetence, transient anorexia and lethargy, mild central nervous system signs (e.g. mild depression and mild ataxia), diarrhoea and colic have been observed in horses. In very rare cases sweating has been reported. If signs of dose intolerance develop, treatment should be stopped for 2 to 3 days and reinstated at one-half of the previous dose. The total daily dose may then be titrated back up to the desired clinical effect by 0.5 mg increments every 2 to 4 weeks.
Pregnancy: Use only according to the benefit/ risk assessment by the responsible veterinarian. The safety of this product has not been demonstrated in pregnant mares. Laboratory studies in mice and rabbits have not produced any evidence of teratogenic effects. Reduced fertility was seen in mice at a dose of 5.6 mg/kg body weight per day.
Lactation: The use is not recommended in lactating horses, in which the safety of this product has not been demonstrated. In mice, reduced body weights and survival rates in the progeny were attributed to the pharmacological inhibition of prolactin secretion resulting in lactation failure.
Use with caution if the product is co-administered with other drugs known to affect protein binding. Do not administer concurrently with dopamine antagonists, such as neuroleptics (phenothiazines - e.g. acepromazine), domperidone, or metoclopramide, as these agents may reduce the effectiveness of Pergolide. There is no clinical experience with massive overdose.
Withdrawal period
Not authorised for use in horses intended for human consumption. The horse must have been declared as not intended for human consumption under national horse passport legislation. Not authorised for use in mares producing milk for human consumption.
