Usage
Dexamethasone Injection solution should be administered as directed by your veterinarian.

Ensure your pet always has access to fresh, clean drinking water while taking this medication.
Injectable medications require needles, syringes, and a designated sharps disposal container. These are not included with the medication and must be purchased separately.
Please consult your veterinarian for guidance regarding appropriate needle and syringe sizes for your pet.
For general injectable use (aseptic technique):
Aseptic technique refers to a set of practices designed to minimize the risk of contamination and infection during medical procedures. These practices can also be applied to the handling and administration of injectable medications to your pet to help reduce the risk of post-injection bacterial infections.
Wash your hands thoroughly with soap and water before and after administration.
Use a new, sterile needle and syringe for each injection. Needles and syringes should never be reused.
Do not touch the needle, syringe tip, or vial stopper (once it has been wiped with alcohol) to any surface to avoid contamination.
Adequately clean and disinfect the vial stopper with an alcohol wipe, then allow it to dry before inserting the sterile needle/syringe.
Withdraw and administer the prescribed dose as directed by your veterinarian.
Dispose of the needle/syringe immediately after use into a proper sharps disposal container.
Missed doses
Administer the dose as soon as possible. If it is almost time for the next dose, skip the missed dose and continue with the regular schedule. Do not administer more medication than prescribed or two doses at once.
Storage
Store in a cool, dry place at a controlled room temperature (68 to 77°F), or as otherwise indicated by the manufacturer packaging/product insert. Protect from freezing.
Keep the vial protected from light and out of the reach of children and pets. Store away from heat and direct sunlight. Do not store in the bathroom, near the kitchen sink, or in damp places. The medicine may break down if exposed to heat or moisture.
Side effects
Many side effects of corticosteroids are linked to high doses or prolonged usage; however, side effects may still occur during short-term therapy. Your veterinarian may provide specific instructions to help avoid or lessen these effects.
The most common side effects of this medication are excessive thirst, urination, and/or appetite.
Other possible side effects include (but may not be limited to) dull/dry haircoat, weight gain, panting, GI effects (vomiting, diarrhea, GI ulceration), weakness, muscle wasting, and mild behavioral changes (e.g., depression, lethargy).
Contact your veterinarian immediately if your pet has complete appetite loss; high blood sugar; atypically low energy level; extreme behavioral changes (e.g., aggression), bloody vomit; or black, tarry stools.
Notify your veterinarian if your pet experiences any of the effects described above, or if you notice any other side effects that are persistent or troublesome.
If you notice anything unusual, please consult your veterinarian.
Precautions
Inspect the vial before each use. Do NOT use this medication if the solution changes in appearance (e.g., color, cloudiness, presence of visible particles, etc). These may be signs that the product is contaminated and no longer fit for use.
Do NOT discontinue this medication abruptly, especially if your pet has been taking it on a regular basis. Please consult your veterinarian before making any changes to the prescribed dosing schedule.
Do NOT use this medication in food animal species (e.g., horses intended for food, veal calves).
Do NOT administer this medication to animals with a current viral or fungal infection, tuberculosis, chronic nephritis (kidney inflammation), hyperadrenocorticism (Cushing’s disease), congestive heart failure, diabetes, osteoporosis, or that are taking any other anti-inflammatory (e.g., corticosteroids, NSAIDs) medications.
Use with caution in animals with a current systemic bacterial infection, kidney or liver impairment/disease, corneal ulcers, bleeding disorders, or hypertension (high blood pressure). Caution should also be exercised in young and growing animals when used long-term, as steroid medications can affect normal growth.
Steroid medications can weaken your pet's immune system, making it easier for them to get an infection (or worsen an existing one). Vaccines should not typically be administered while on this medication.
Safe use of this medication has not been established and should be used with caution in breeding, pregnant, or lactating animals. Discuss the risks of using this medication with your veterinarian if your pet is in one of these groups.
Do not administer to animals with a known history or suspected allergy/hypersensitivity to any corticosteroid drug, including this medication or any of its ingredients. Allergic reactions to medications may occur. Be sure to inform Vetsource and your veterinarian if your pet has any known drug sensitivities or allergies.
If your pet displays symptoms of an allergic reaction, discontinue therapy and call your veterinarian immediately or seek emergency veterinary attention. Symptoms may include (but are not limited to): swollen lips, tongue, face, or airways; difficulty breathing; agitation; profuse salivation; and widespread hives or itching.
