Information in this page has been entered to support the current volumes of Wildpro and further information will be added as new volumes are completed. This page is not intended to substitute for the manufacturer's data sheet and the information is not yet complete for all species, or for all contra-indications etc.

CAUTION: Before any pharmaceutical product is used, the manufacturer's data sheet, containing information on uses, dosage and administration, contra-indications, warnings etc., should always be consulted. It is important to remember that licensing of pharmaceutical products for use in a particular species/condition, as well as mandatory meat and milk withdrawal times for food-producing animals, varies between countries and changes with time. Withdrawal times also may vary between different pharmaceutical formulations and depending on route of administration. In the EU, the prescription cascade must be followed (see LCofC1.2H and W564.Apr05.w1); note that specific restrictions apply for food-producing animals. In the USA, FARAD may be consulted regarding residues and meat and milk withdrawal times.

Doses / Administration Routes / Frequencies

Use of Drugs (Medication):

  • Before administration of any drug the manufacturer's datasheet must be consulted regarding operator safety, relevant withdrawal times etc.
  • Many drugs are not registered for use in particular species and care should be taken in their use, with proper regard for possible toxic effects. Consideration should be give to relevant legislation regarding the use of drugs.
  • In the UK, guidelines regarding the use of drugs are set out in the Royal College of Veterinary Surgeons Guide to Professional Conduct 2000: (See: LCofC1 - RCVS Guide to Professional Conduct 2000 - Choice of Medicinal Products).

Erinaceus europaeus - West European Hedgehog:
  • 2.5 mg/kg subcutaneously. For inflammation. (B22.27.w3)
  • 10 mg/kg subcutaneously. For shock. (B22.27.w3)
Atelerix albiventris - Four-toed hedgehog:
  • 2.5 mg/kg subcutaneously every 12 hours; 10 mg/kg for shock. (J204.59.w1)
"Hedgehog" (species not distinguished between Atelerix albiventris - Four-toed hedgehog or Erinaceus europaeus - West European Hedgehog):
  • 2.5 mg/kg subcutaneously every 12 hours. For allergies. (B267)
  • 10 mg/kg subcutaneously or intramuscularly. For shock. (B267)

Elephants:

Bears:

  • In general: "Domestic dog drugs and dosages are used to treat bears." (B336.51.w51) 
  • In a bear with Inhalant Allergic Dermatitis, oral prednisolone: 80 mg on days 1,3,5,7,9 and 40 mg on days 2,4,6,8,10, then reducing to 60 mg on "odd" numbered days and 25 mg on even days, through the summer and fall pollen seasons, together with antihistamines, gave good control of the pruritis.

Toxic Information

Toxic effects of Pharmaceutical Products
Contraindications / Precautions
  • Prolonged treatment with glucocorticoids may suppress the hypothalamic-pituitary-adrenal axis (HPA) and result in atrophy of the adrenal glands.  (B201.7.w7)
    • Prolonged therapy should be avoided if possible, to minimise the risk of precipitating signs of adrenal insufficiency in the event of superimposed stress or when therapy ceases. (B201.7.w7)
  • Use corticosteroids with caution during pregnancy due to the risk of causing fetal abnormalities and abortion.  (B201.7.w7)
  • In horses: use of corticosteroids is contraindicated for treatment of laminitis. (B201.7.w7)
  • Glucocorticoids and vaccines should not be administered concurrently with one another. (B201.7.w7)
  • If the course of therapy lasts for longer than two weeks, the dose of prednisolone should not be stopped abruptly but reduced gradually.  (B201.7.w7)
  • For prolonged treatment, the dose should be tapered to the lowest level clinically acceptable for maintenance of the required effect then a gradual transition made to give twice this dose on alternate days. In dogs the dose should be given in the morning to minimise suppression of the HPA axis; for cats evening medication has been suggested (however the diurnal rhythm of the HPA in cats is uncertain).  (B201.7.w7)
Adverse Effects / Side Effects /  Warnings
  • In horses: use of corticosteroids may induce laminitis. (B201.7.w7)
  • Long term administration of glucocorticoids may cause iatrogenic hyperadrenocorticism.  (B201.7.w7)
  • Administration of corticosteroids may cause hepatomegaly and a concurrent  rise in serum levels of hepatic enzymes.  (B201.7.w7)
  • Administration of glucocorticoids may change the required dosage of insulin in diabetic patients and may unmask diabetes in individuals not previously diagnosed as diabetic.  (B201.7.w7)
  • Glucocorticoid treatment may cause gastric and colonic ulceration.  (B201.7.w7)
  • The immunosuppression and modification of inflammatory processes by glucocorticoids may facilitate progression of infectious disease.  (B201.7.w7)
    • If glucocorticoids are used in an individual with a known infection, an appropriate antimicrobial drug should be administered concurrently. (B201.7.w7)
  • Glucocorticoids have catabolic effects including: muscle wasting, cutaneous atrophy, telogen arrest of hair follicles, delay in healing of wounds, suppression of both corneal stroma repair and epithelial repair in cases of corneal ulceration. (B201.7.w7)

Reported side effects from glucocorticoid treatment include effects on blood cells and blood chemistry, central nervous system, endocrine system, gastro-intestinal system, renal system, musculoskeletal system and skin, as well as reduction in growth, redistribution of body fat, increased risk of infection, enhanced spread of infection and poor wound healing. (B270.33.w33)
