Duration of treatment will depend upon the severity of the condition and the response obtained. The duration of treatment and/or frequency of the dosage may be reduced, but care should be taken not to discontinue therapy prematurely.
Otitis externa The external ear and ear canal should be properly cleaned and dried before treatment. Remove foreign material, debris, crusted exudates, etc., with suitable nonirritating solution. Excessive hair should be clipped from the treatment area of the external ear. Instill 3 to 8 drops of Gentamicin Sulfate with Betamethasone Valerate Otic Solution (approximately room temperature) into the ear canal twice daily for seven to fourteen days.
Superficial infected lesions The lesion and adjacent area should be properly cleaned before treatment. Excessive hair should be removed. Apply a sufficient amount of Gentamicin Sulfate with Betamethasone Valerate Otic Solution to cover the treatment area twice daily seven to fourteen days.
Caution
Federal law restricts this drug to use by or on the order of a licensed veterinarian.
Contraindications
If hypersensitivity of any of the components occurs, treatment with this product should be discontinued and appropriate therapy instituted.
Concomitant use of drugs known to induce ototoxicity should be avoided.
This preparation should not be used in conditions where corticosteroids are contraindicated.
Do not administer parenteral corticosteroids during treatment with Gentamicin Sulfate with Betamethasone Valerate Otic Solution.
Precautions:
The antibiotic sensitivity of the pathogenic organism should be determined prior to the use of this preparation. Use of topical antibiotics occasionally allows overgrowth of non-susceptible bacteria, fungi or yeasts. If these cases, treatment should be instituted with other appropriate agents as indicated.
Adverse systemic reactions have been observed following the oral ingestion of some topical corticosteroid preparations. Patients should be closely observed for the usual signs of adrenocorticosteroid overdosage, which include sodium retention, potassium loss, fluid retention, weight gains, polydipsia and/or polyuria. Prolonged use or overdosage may produce adverse immunosuppressive effects.
Experimentally it has been demonstrated that corticosteroids, especially at high dosage levels, may result in delayed wound healing. An increase in the incidence of osteoporosis may be noted, mainly in the elderly, with prolonged use of these compounds. Their use in older dogs during the healing stages of bone fracture in not indicated for the reason listed above.
Use of corticosteroids, depending on dose, duration, and specific steroid, may result in inhibition of endogenous steroid production following drug withdrawal. In patients presently receiving or recently withdrawn from systemic corticosteroid treatments, therapy with a rapidly acting corticosteroid should be considered in unusually stressful situations.
Cautions:
Before instilling any medication into the ear, examine the external ear canal thoroughly to be certain the tympanic membrane is not ruptured in order to avoid the possibility of transmitting infection to the middle ear as well as damaging the cochlea or vestibular apparatus from prolonged contact. If hearing or vestibular dysfunction is noted during the course of treatment, discontinue use of Gentamicin Sulfate with Betamethasone Valerate Otic Solution.
Warning:
Clinical and experimental data have demonstrated that corticosteroids administered orally or parenterally to animals may induce the first stage of parturition when administered during the last trimester of pregnancy and may precipitate premature parturition followed by dystocia, fetal death, retained placenta and metritis. Additionally, corticosteroids can induce cleft palates in offspring when given to pregnant animals during the period of palate closure of the embryos. Other congenital anomalies, including deformed forelegs, phocomelia and anasarca, have been reported in offspring of dogs which received corticosteroids during pregnancy.
Avoid ingestion.
Side Effects:
Side effects such as SAP and SGPT enzyme elevations, weight loss, anorexia, polydipsia and polyuria have occurred following the use of parenteral or systemic synthetic corticosteroids in dogs. Vomiting and diarrhea (occasionally bloody) have been observed in dogs and cats. Cushing's syndrome in dogs has been reported in association with prolonged or repeated steroid therapy.
Storage:
Store between 2°C and 25°C (36°F and 77°F).
