How Much Dexamethasone To Give A Horse Orally? (Perfect answer)

Dexamethasone can be given IV, IM and the solution can even be given orally (it is absorbed quite well from the GI tract). In an emergency case of hives or wheals in which you cannot contact your vet, you could give 1cc per 100 lbs (of the 2mg/ml strength) by either IM or oral route.

  • Based on the bioavailability of oral dexamethasone, daily oral doses of 0.1 to 0.2 mg/kg should also be effective at improving the respiratory function of RAO-affected horses. Another effective option is the use of isoflupredone at a dose of 0.03 mg/kg administered once a day.

How much dexamethasone do you give a horse?

Efficacy of oral and intravenous dexamethasone in horses with recurrent airway obstruction

Although dexamethasone has been shown to be effective in the treatment of recurrent airway obstruction (RAO), the time it takes for the effects to manifest and the duration of action are unknown. It is also unclear whether dexamethasone administered orally with or without fasting is as effective as dexamethasone administered intravenously. The objectives of this study were to document the time of start of effect and the duration of action of a dexamethasone solution given intravenously or orally with and without fasting, and to compare the results.

The effects of dexamethasone i.v.

Six comparable horses were utilized in the study.

induced a considerable increase in lung function within 2 hours, with a peak effect occurring between 4 and 6 hours.

  • When compared to saline, the duration of effect was statistically significant for all dexamethasone doses for 30 h.
  • It was shown that feeding decreased the bioavailability of dexamethasone per os at a dosage of 0.164 mg/kg bwt given to fed horses, whereas feeding decreased the bioavailability of dexamethasone per os at a dose of 0.082 mg/kg bwt provided to fasted horses.
  • Oral administration of a bioequivalent dosage of the same solution to fasting horses is equally efficacious as intravenous treatment and has the advantage of having a longer duration of action than intravenous administration.
  • Potential significance:Oral administration of a dexamethasone solution meant for intravenous administration to fasting horses has been shown to be an effective therapy for RAO-affected animals.

Dexamethasone 10 mg/scoop, Oral Powder, 30 Scoops (5cc Scoop)

Recurrent airway obstruction (RAO) is the term used to describe a type of respiratory illness condition that occurs on a regular basis in horses. Chronic obstructive pulmonary disease (COPD) and “heaves” are other names for the condition. Asthma in horses is identical to human asthma, and it is a prevalent cause of the continuous coughing that some horses experience. For the sake of this discussion, suffice it to note that a variety of words and acronyms have been used throughout the years to refer to the many inflammatory airway disorders that cause coughing and respiratory discomfort in horses.

1 When the above syndrome manifests itself in young horses, it is referred to as “inflammatory airway disease” (IAD), and it is characterized by exercise intolerance and intermittent cough in horses that appear to be in normal condition when at rest, according to the American Veterinary Medical Association.

According to the existing research, these horses can be fully recovered with therapy; on rare occasions, such horses can heal on their own without treatment.

RAO and COPD in Horses

Residual airway obstruction (RAO) in horses is often characterized by an excessive production of mucus, narrowing of the airway (bronchoconstriction), and broncho spasm. RAO is also known as broken wind, chronic airway reactivity, or chronic airway reactivity. “In contrast to horses with IAD, horses with RAO are not normal at rest and typically have an elevated respiratory rate and/or cough,” says the author. Chronic cough, nasal discharge, exercise intolerance, and respiratory trouble are the most prevalent symptoms of RAO.

  • The majority of infected horses do not have a fever unless they have developed a secondary bacterial pneumonia.
  • The majority of the time, COPD develops in horses who have acquired an allergic response to dust allergens in the environment.
  • Typically, the horses that are impacted are having allergic responses to environmental allergens such as fungal spores or pollen, among other things.
  • It is for this reason that COPD tends to be more prevalent in stabled horses, where dust and fungal spores are frequently seen.
  • When a horse develops an allergic reaction to a chemical such as this, the tiny airways of the afflicted horse are the most severely harmed when the allergen is breathed.
  • 1,2 These factors work together to narrow the horse’s airway’s width, making it more difficult for him to breathe.
  • COPD is most commonly associated with older, stabled horses, but it can afflict horses of any age, as well as horses on pasture.
  • Its development is often slow, with the first indications of the disease frequently being unnoticeable.

Eliminating the Variables

If the horse’s symptoms are not immediately apparent, the first step the owner or stable manager should do is to minimize any factors that might be a contributing factor to his or her discomfort. Essentially, this means avoiding problems in the first place, which often entails cleaning and good (or better) horse husbandry. In order to alleviate symptoms, the first step is to reduce the amount of dust present in the horse’s quarters. It doesn’t matter what the reason is; this can help you breathe better because dust is a respiratory irritant that can accumulate in the lungs and clog airways.

Equine owners should keep their animals indoors if the weather is excessively hot or cold, for obvious reasons, since severe temperatures can aggravate any respiratory ailment.

When it comes to the barn, everything that can be done to supply the horses with fresh, clean air may make a major difference in their ability to breathe comfortably.

Dexamethasone / Dexamethasone Sodium Phosphate

It is available as an injectable, oral, and ocular drug. Dexamethasone is a glucocorticoid steroid that may be used to treat a variety of conditions. With no mineralocorticoid action, it is 30 times more powerful than hydrocortisone and has a longer half-life than hydrocortisone. 4 Systemic fungal infections are a contraindication, and caution should be exercised when administering it to animals with active bacterial infections, corneal ulcers, hyperadrenocorticism (i.e., Cushing’s disease), diabetes mellitus, osteoporosis, chronic psychotic reactions, a predisposition to thrombophlebitis, hypertension, and renal insufficiency.

It is used to treat a range of horse illnesses, including arthritis and allergic responses as well as heaves.

Most typically, it is given orally (PO), intravenously (IV), or intramuscularly (IM) (IM).

It is most commonly used in the treatment of rheumatic, dermatologic, allergy, and other disorders that are known to be susceptible to anti-inflammatory corticosteroids, such as psoriasis and arthritis.

Dexamethasone Adverse Effects and Warnings

In addition to a dull/dry coat, weight gain, panting, vomiting, and diarrhea (particularly when large parenteral or oral dosages are used), dexamethasone can cause hypercoagulability, hyperlipidemia, activation or aggravation of diabetes mellitus, muscle atrophy, and behavioral abnormalities (eg, depression, lethargy, aggression). 5Glucocorticoids have been shown to cause growth retardation in young animals in the past. 4 There have been no reports of major adverse events in horses treated with dexamethasone at the recommended dosage.

Dexamethasone Dosages for Horses

Dexamethasone has been classified as a CLASS 4 DRUG by the International Uniform Classification Guidelines for Foreign Substances published by the Association of Racing Commissioners. For horses with heaves, the following dexamethasone dosage is recommended, as is the following dexamethasone dosage for horses with COPD (from fromPlumb’s Veterinary Drugs): Drugs used as anti-inflammatory and glucocorticoid agents include dexamethasone 2.5 – 5 mg (total dose) IV or IM; dexamethasone sodium phosphate 2.5 – 5 mg (total dose) IV; and dexamethasone sodium phosphate 2.5–5 mg (total dose) IV.

Adjunctive treatment of recurrent airway obstruction (extra-label):

A) In the case of a 500-kg horse, administer dexamethasone 40 mg (total dose; NOT mg/kg) intramuscularly once every other day for three treatments, followed by 35 mg (total dose; NOT mg/kg) IM once every other day for three treatments, followed by 30 mg (total dose; NOT mg/kg) IM once every other day for three treatments, and continue tapering until the horse is weaned off this therapy completely.

The following doses of dexamethasone sodium phosphate should be used for short-term therapy with environmental control: 0.1 mg/kg IM once daily for 4 days, 0.075 mg/kg IM once daily for 4 days, and 0.05 mg/kg IM once daily for 4 days Except for the findings of bronchoalveolar lavage cytology, PO prednisolone (1 mg/kg PO for 4 days, 0.75 mg/kg PO for 4 days, and 0.5 mg/kg PO for 4 days) was shown to be equally effective as IM dexamethasone, with the exception of the results of bronchoalveolar lavage cytology.

When it comes to lowering clinical symptoms, airway inflammatory cells, and the bronchoprovocative histamine response, dexamethasone 0.05 mg/kg intramuscularly every 24 hours is equally effective as inhaled fluticasone.

The following medications are used: d) Dexamethasone 0.05 mg/kg PO once daily for 7 days or prednisolone 2 mg/kg PO once daily for 7 days Both medications are effective, however dexamethasone was shown to be the most effective.

Dexamethasone suppression test to diagnose pituitary pars intermedia dysfunction (extra-label):

A) 20 mg intramuscularly (total dosage; NOT mg/kg). Normal values: Cortisol levels should decline by 50% in 2 hours, 70% in 4 hours, and 80% in 6 hours, according to the manufacturer’s recommendations. At 24 hours, cortisol levels should have remained down by around 30% of the presuppression level. 44 Seasonal fluctuation may have an impact on the outcomes. Dexamethasone 0.04 mg/kg IM can be delivered when baseline cortisol (serum or plasma) is taken, and a second cortisol sample can be collected 18 to 20 hours later.

Testing undertaken in the autumn is more likely to provide false-positive findings than testing performed in the spring.

Where to buy Dexamethasone powder for horses

There are several pharmaceutical manufacturers and veterinary custom compounding companies that sell dexamethasone in the United States, as well as online pharmacies. NEXGEN Pharmaceuticals’ DEXAMETHASONE 10 MG/SCOOP is indicated for the treatment of acute musculoskeletal inflammations such as bursitis, osselets, carpitis, myositis, tendonitis, and sprains, among other things. If bony changes are present in any of these conditions, joints, or accessory structures, it is not possible to predict whether or not dexamethasone will be effective.

Dexamethasone for Horses

Look for Dosage Forms that are currently available.

General Drug Information and Indications

When it comes to illnesses or disorders in which the immune system plays a prominent role, dexamethasone is a synthetic corticosteroid hormone that is used to regulate inflammation. The anti-inflammatory effects of dexamethasone are approximately twenty-five times more potent than those of endogenous cortisol, according to some studies. Excessive use of the corticosteroid dexamethasone in horses is usually associated with the treatment of allergic responses such as respiratory allergies, chronic obstructive pulmonary disease (heaves), hives, itching, and inflammatory illnesses, such as arthritis.

Emergency medicine and the treatment of autoimmune illnesses necessitate the use of greater dosages of corticosteroids than are typically required in other situations.

Other active chemicals, such as antibiotics, antifungals, and miticides, may be used in topical preparations for topical application.

The use of dexamethasone in animals, including horses, has been approved by the FDA. It may be necessary to have a specialist pharmacy synthesize the proper dose form if the right dosage form is not available from a veterinary pharmaceutical manufacturer.

How to Give This Medication

This medicine should be administered to your horse in the precise manner prescribed by your veterinarian. If you forget to administer a dosage of dexamethasone to your horse, administer the following dose as soon as you recall or, if it is close to the next planned dose, resume to the usual schedule of administration. Do not take a second dosage to make up for lost time. After administering this medicine to your horse, thoroughly wash your hands.

Side Effects

Make an appointment with your veterinarian as soon as you notice any negative effects. Corticosteroids, such as dexamethasone, are extremely potent medications. While they offer a variety of beneficial benefits, they also have the potential to induce undesirable side effects if they are misused or taken in an incorrect manner. Systemic adverse effects are largely depending on the dose and duration of the treatment regimen. Laminitis is a side effect that can occur when corticosteroids are administered to a horse.

When dexamethasone is used for an extended period of time, it might cause excessive urine (polyuria), increased water intake (polydypsia), and muscle atrophy.


Keep this, as well as any other medications, out of the reach of children. Dexamethasone is a prescription medication that should be administered in accordance with your veterinarian’s instructions and only to the animal for which it has been specifically prescribed. This drug should not be administered to anyone. It is recommended to avoid or use dexamethasone with great caution in any horse or pony that has other risk factors for laminitis, such as being overweight. Equine pituitary disorders, horse Cushing’s disease, and equine metabolic syndrome are examples of what is considered to be abnormal.

  • Gastric ulcers can be caused or exacerbated by corticosteroids such as dexamethasone.
  • Corticosteroids are drugs that reduce the immunological response.
  • Horses who have received dexamethasone may not respond to immunizations as expected.
  • Systemic corticosteroids can also hide indications of illness, such as an increased fever, if they are administered in large doses.
  • Despite the fact that most veterinarians attempt to avoid them, there are some circumstances in which the advantages exceed the potential hazards.

Depending on whether the animal has been taking dexamethasone for a chronic ailment, the amount of dexamethasone may need to be decreased in order for the animal’s body to resume normal production of corticosteroid hormone. Before quitting this medication, be sure to talk with your veterinarian.

Drug Interactions

Make careful to discuss with your veterinarian any drugs or supplements that your horse may be getting at this time. If dexamethasone is used at the same time as other ulcer-causing medications such as nonsteroidal anti-inflammatory medicines (NSAIDs) (phenylbutazone, flunixin, and others), the risk of stomach ulcers may be enhanced. There is an increased risk of electrolyte imbalances in animals getting the diuretic furosemide while being treated with dexamethasone, which is attributable to calcium and potassium losses.


Please notify your veterinarian or the American Society of Poison Control Center at 888.426.4435, if you feel your horse or another animal has been accidently overdosed or has taken this medicine inadvertently. Always remember to bring the prescription container with you when you take your horse to the veterinarian for a procedure. You should contact the National Capital Poison Center at 800.222.1222 if you or someone else has mistakenly consumed this drug.


Dexamethasone comes in a variety of strengths and dosage forms, each with its own set of storage needs. Read the information on the prescription you receive or ask your pharmacist about the storage requirements for the medication you receive.

More Information About This Medication

The adrenal gland produces corticosteroids, which are hormones that are beneficial to the body. Cortisol is a corticosteroid hormone that occurs naturally in the body. Corticosteroids are required for survival and have an impact on the metabolism of animals as well as the operation of all cells and organ systems. It is believed that their anti-inflammatory properties are attributable to numerous biological mechanisms. The mineralocorticoids and the glucocorticoids are the two principal kinds of hormones generated by the adrenal gland, with the mineralocorticoids being the more common.

  • As a result, there are several distinct corticosteroid medicines available, and various medical diseases are treated with a variety of different corticosteroid treatments depending on the pharmacology of each specific drug (e.g.
  • Mineralocorticoids are the name given to the various types of hormones that are generated by the adrenal gland.
  • It has been shown that there is considerable overlap in function between mineralocorticoids and glucocorticoids.
  • When corticosteroid medicines are administered systemically, the general practice is to provide the preparation with the shortest duration of action, at the lowest dosage level, and for the shortest amount of time feasible, unless otherwise indicated.

The use of corticosteroids for an extended period of time or in an incorrect manner might produce life-threatening hormonal and metabolic abnormalities.

A relative contraindication to this procedure is the presence of congestive heart disease, diabetes, or osteoporosis. The use of this medication during the viremic stage of viral illnesses is prohibited.


Amounts of clinical and experimental evidence have demonstrated that corticosteroids given to animals orally or parenterally during the last trimester of pregnancy can cause the first stage of parturition and can precipitate parturition, which may result in dystocia, fetal death, a retained placenta, and metritis in the mother. Additionally, corticosteroids given to dogs, rabbits, and rodents during pregnancy have been linked to the development of cleft palates. There have been reports of other congenital malformations in the progeny of dogs that took corticosteroids during pregnancy, including malformed forelegs, phocomelia, and anasarca, amongst other things.

Calves that will be processed for veal should not be fed this supplement.

Side Effects

Following the administration of synthetic corticosteroids to dogs, side symptoms such as increases in the enzymes SAP and SGPT, weight loss, anorexia, polydipsia, and polyuria have been seen. Dogs and cats have been reported to have vomited and had diarrhea (which was occasionally bloody). Several reports of Cushing’s syndrome in dogs have been published in connection with prolonged or recurrent steroid administration. Corticosteroids are believed to be the cause of laminitis in horses.
