What is Primor?

Primor (sulfadimethoxine/ormetoprim) tablets are indicated for dogs with skin and soft-tissue infections (wounds and abscesses) in dogs caused by strains of Staphylococcus aureus and Escherichia coli and urinary tract infections caused by Escherichia coli, Staphylococcus spp. and Proteus mirabilis susceptible to sulfadimethoxine/ormetoprim. Primor requires a prescription from your veterinarian, and is sold per tablet.

For:

Dogs

Benefits:

  • Potentiation of sulfadimethoxine (SDM) with ormetoprim (OMP) provides increased efficacy and broadens spectrum of activity to include some sulfonamide-resistant organisms.
  • The only veterinary-approved potentiated sulfonamide with once-daily dosing.
  • Extended half-life of SDM produces 24-hour therapeutic blood concentrations.
  • Scored tablets are available in 4 sizes for convenient dosing

Cautions:

Primor should not be used in dogs with liver damage, blood disorders, or in those with a history of sulfonamide hypersensitivity. Do not use in pregnant or nursing animals. Have plenty of water available for your pet and pet should be encouraged to drink water while being given Primor. Tell your veterinarian what other medications or treatments your pet is receiving, before giving this medication to your pet. Primor is not for use in animals allergic to it or other sulfa drugs. Not for human use. For use in dogs only. Keep out of reach of children.

What happens if I miss giving a dose:

Give the missed dose as soon as possible. However, if it is almost time for the next regularly scheduled dose, skip the missed dose and give the next one as directed. Do not give a double dose of the medication.

Possible side effects of Primor:

Conditions reported following use of sulfona­mides or potentiated sulfonamides include polyarthritis, urticaria, facial swelling, fever, hemolytic anemia, polydypsia, polyuria, hepatitis, vomiting, anorexia, diarrhea, and neurologic disorders. In rare instances, neurologic signs including behavioral changes, ataxia, seizures, aggression, and hyperexcitability have been reported. Keratitis sicca, possibly due to prolonged use of sulfonamides, has been reported. Individual animal hypersensitivity may result in local or generalized reactions. Anaphylactoid reactions, although rare, may also occur. Sulfa crystals may appear in your pet's urine. Your pet should be allowed to drink plenty of water while taking this medication. Talk to your veterinarian about any side effect that seems unusual to your pet. If your pet experiences an allergic reaction, signs may include facial swelling, hives, scratching, and sudden onset of diarrhea, vomiting, shock, seizures, or coma. If these signs occur, contact your veterinarian immediately.
