Potentiated sulfonamide antimicrobial agent used to treat many infections common in small animals.
Dogs, cats and other small animals
Trimethoprim-sulfa is a potentiated sulfonamide antimicrobial used to treat certain bacterial and protozoal infections in veterinary medicine.
Bacterial urinary tract infections, skin infections, and other soft tissue infections; also used for protozoal infections.
The combination of trimethoprim with a sulfonamide gives this medication a broader spectrum of activity against susceptible microorganisms with less antibiotic resistance than either component alone. Potentiated sulfa drugs kill microorganisms by inhibiting enzymes, causing the bacteria to die.
Trimethoprim-sulfa should be stored at room temperature.
If a dose is missed, continue with the next dosage at the scheduled time.
Signs of an overdose include nausea, vomiting, diarrhea, depression, confusion and facial swelling. Call your veterinarian immediately if you suspect your pet has received an overdose of trimethoprim-sulfa.
Trimethoprim-sulfa may interact with: * Amantadine * Antacids * Cyclosporine * Digoxin * Thiazide diuretics * Oral hypoglycemic agents * Methotrexate * Phenytoin * Tricyclic antidepressants * Warfarin
Trimethoprim-sulfa should be used with caution in patients with: * Decreased kidney function * Decreased liver function * Urinary obstructions or urolithiasis (stones in the urinary tract)
