Cat & Dog - Fludrocortisone Acetate

Why has my veterinary surgeon prescribed this medicine?

Fludrocortisone is a synthetic adrenocortical steroid with mineralocorticoid activity. In Addison's disease your pet's adrenal gland is unable to produce mineralocorticoids. Mineralocorticoids help to maintain the body's fluid balance and blood pressure. Fludrocortisone is given to replace mineralocorticoids.

Fludrocortisone is not available as a veterinary preparation in the UK. Your veterinary surgeon may ask you to sign a consent form so a preparation licensed for humans can be used to treat your pet.

Potential side effects

  • Although a drug has potential side effects, it does not mean that there is necessarily a high risk of any of these occurring. Tell your veterinary surgeon if you think your pet may be pregnant.
  • Your veterinary surgeon will monitor your pet's blood to check the level of sodium and potassium.
  • Dizziness is a potential side effect. If this effect is seen, contact your veterinary surgeon.
  • Animals with Addison's disease may be unable to produce glucocorticoids, substances that your pet needs to cope in times of stress. Your veterinary surgeon may prescribe glucocorticoids (e.g. prednisolone) to give when stressful situations are anticipated.
  • Other side effects may occur. If you notice anything unusual, contact your veterinary surgeon.

Possible drug interactions

  • Make sure to tell your veterinary surgeon what other medication you are giving to your pet.
  • Quite often your veterinary surgeon may prescribe two different medications, and a drug interaction may be anticipated. In this case, your veterinary surgeon may vary the dose and/or monitor your pet more closely.
  • Drugs may interact such that they can cause an increased or decreased effect or side effects. Although drug interactions may occur, it does not mean that there is necessarily a high risk of any of these occurring.
  • Contact your veterinary surgeon if your pet experiences any unusual reactions when different medications are given together.
