SMZ-TMP (Sulfamethoxazole and Trimethoprim) treats a variety of bacterial and protozoal infections in dogs and cats, including urinary tract, respiratory, gastrointestinal and skin infections. The active ingredients, sulfamethoxazole and trimethoprim, work together for improved effectiveness against infection.
Side Effects: Common side effects in dogs includes reduced appetite, vomiting and diarrhea. Cats may experience reduced appetite and increased salivation after giving a dose.

Severe side effects for dogs include dry eye syndrome (keratoconjuctivitis sicca, KCS), difficulty urinating, increased thirst and urination, swelling of the face, lack of energy, difficulty walking and jaundice.

Severe side effects for cats include difficulty urinating, refusal to eat, lack of energy and fever. If your pet experiences any of the severe side effects contact your veterinarian immediately.

Warnings: SMZ/TMP should not be used in pets that are allergic to any of the active ingredients or sulfa, thiazides or sulfonylurea drugs. It should also not be used in pets with severe kidney or liver impairment.

Use with caution in pets with liver, kidney or thyroid disease, and a history of kidney or bladder stones. Use with caution in Doberman pinscher breed as they are susceptible to a serious immune-related condition that can be caused by sulfa drugs.

Overdoses can be very dangerous. Keep out of reach of children and animals.

Always follow the dosage instructions provided by your veterinarian. If you have difficulty giving the medication, contact your veterinarian.

If you miss a dose, give it as soon as you remember. If it is almost time for the next dose, skip the one you missed and go back to the regular schedule. Do not give two doses at once.

This medication should only be given to the pet for whom it was prescribed.

Disposal of Unused Prescription Medications

  1. Return unwanted or unused medications to Revival Animal Health in person, or visit to find a pharmacy near you.
  2. A secondary method of drug disposal is to remove the unwanted medication from any wrappers or containers and place it in a plastic bag with moist coffee grounds or cat litter. This can be disposed of in the regular garbage collection.
  3. Please do NOT dispose of unwanted meds down the drain or toilet, as this may eventually find its way into the human water supply.

Disposal of Medical Sharps

  1. When you're finished with the syringe and needle, do not try to recap, remove, bend or break the needle. This is where most injuries occur.
  2. Dispose the syringe and needle immediately in a nearby sharps container. All sharps must be deposited in a puncture-proof container. Make sure your storage location is child and animal proof.
  3. As with all product handling, make sure you wash your hands after handling medical sharps.

Disposal of Sharps Container

  1. When your sharps container is half-full, sift dry Portland Cement throughout the sharps. Fill the container with water, and rotate until the cement is mixed and the sharps have been distributed throughout the cement mixture. Let cement dry for 24 hours.
  2. Seal the lid of the container tightly and use duct tape to seal. Label the container "Livestock Sharps" to properly identify the contents.
  3. Dispose of the containers in accordance with your state's regulations.
