Trimeprazine with Prednisolone Tablets

For use in dogs

Federal law restricts this drug to use by or on the order of a licensed veterinarian.

Each tablet contains trimeprazine tartrate (USP) 10-[3-(Dimethylamino)-2-methylpropyl]phenothiazine tartrate (2:1) equivalent to trimeprazine, 5 mg, and prednisolone, 2 mg.

The exclusive Trimeprazine with Prednisolone formula combines the antipruritic and antitussive action of trimeprazine with the anti-inflammatory action of prednisolone. A therapeutic effect is attained by administering the tablets twice daily.

1. Antipruritic: Trimeprazine with Prednisolone is recommended for the relief of itching regardless of cause. Its usefulness has been demonstrated for the relief of itching and the reduction of inflammation commonly associated with most skin disorders of dogs such as the eczema caused by internal disorders, otitis, and dermatitis (allergic, parasitic, pustular, and nonspecific). It often relieves pruritus which does not respond to other therapy. With any pruritus treatment, the cause should be determined and corrected; otherwise, signs are likely to recur following discontinuance of therapy.

2. Antitussive: Trimeprazine with Prednisolone has been found to be effective therapy and adjunctive therapy in various cough conditions of dogs. Therefore, in addition to its anti pruritic action, Trimeprazine with Prednisolone is recommended for the treatment of "kennel cough" or tracheobronchitis, bronchitis including all allergic bronchitis, and infections and coughs of nonspecific origin. (Coughs due to cardiac insufficiencies would not be expected to respond to Trimeprazine with Prednisolone therapy.) As with any antitussive treatment, the etiology of the cough should be determined and eliminated if possible. Otherwise, symptoms are likely to recur following discontinuance of therapy.

Note: Trimeprazine with Prednisolone may be administered to animals suffering from acute or chronic bacterial infections provided the infection is controlled by appropriate antibiotic or chemotherapeutic agents.

Clinical and experimental data have demonstrated that corticosteroids administered orally or by injection to animals may induce the first stage of parturition if used during the last trimester of pregnancy and may precipitate premature parturition followed by dystocia, fetal death, retained placenta, and metritis. Additionally, corticosteroids administered to dogs, rabbits, and rodents during pregnancy have resulted in cleft palate in offspring. Corticosteroids administered to dogs during pregnancy have also resulted in other congenital anomalies, including deformed forelegs, phocomelia, and anasarca. If a vasoconstrictor is needed, norepinephrine should be used in lieu of epinephrine. Phenothiazine derivatives may reverse the usual elevating action of epinephrine causing a further lowering of blood pressure.

Keep Trimeprazine with Prednisolone Tablets in a secure location out of reach of dogs, cats, and other animals to prevent accidental ingestion or overdose.

All the precautions applicable to cortisone and to phenothiazine derivatives apply also to Trimeprazine with Prednisolone. Possible side effects attributable to corticosteroids include sodium retention and potassium loss, negative nitrogen balance, suppressed adrenal cortical function, delayed wound healing, osteoporosis, elevated levels of SGPT and SAP, and vomiting and diarrhea (occasionally bloody). Cushings syndrome in dogs has been reported in association with prolonged or repeated steroid therapy. Possible increased susceptibility to bacterial invasion and/or the exacerbation of preexisting bacterial infection may occur in patients receiving corticosteroids. As noted above, however, this problem can be avoided by concomitant use of appropriate anti-infective agents. Possible side effects attributable to phenothiazine derivatives include sedation; protruding nictitating membrane; blood dyscrasias; intensification and prolongation of the action of analgesics, sedatives and general anesthetics; and potentiation of organophosphate toxicity and the activity of procaine hydrochloride.

It should be remembered that the premonitory signs of cortisone overdosage, such as sodium retention and edema, may not occur with prednisolone. Therefore, the veterinarians must be alert to detect less obvious side effects, such as blood dyscrasias, polydipsia, and polyuria.

The appearance and severity of side effects are dose related and are minimal at the recommended dosage level. If troublesome side effects are encountered, the dosage of Trimeprazine with Prednisolone should be reduced and discontinued unless the severity of the condition being treated makes its relief paramount.

Prolonged treatment with Trimeprazine with Prednisolone must be withdrawn gradually. 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 steroid treatments, therapy with a rapidly acting corticosteroid should be considered in unusually stressful situations.

The same dosage schedule may be followed for both antipruritic and antitussive therapy.

After 4 days, reduce dosage to 1/2 of the initial dose or to an amount just sufficient to maintain remission of symptoms. Individual animal response will vary and dosage should be adjusted until proper response is obtained.

Store at 20° to 25°C (68° to 77°F), excursions permitted to 40°C (104°F). Protect from light.
