What is Stomorgyl?

Stomorgyl is a medication that contains two antibiotics - Spiramycin and Metronidazole. These antibiotics work together to fight against a range of bacteria. Stomorgyl is primarily prescribed for treating infections and inflammations caused by these bacteria, especially those related to mouth problems in cats and dogs. Stomorgyl can be used to treat conditions like Stomatitis, Gingivitis, and Pyorrhea halitosis.

How does it work?

Spiramycin works by inhibiting protein synthesis in bacteria, limiting their growth, while Metronidazole damages the DNA leading to cell death. This combination makes Stomorgyl particularly effective against a broad spectrum of pathogens, especially in dental and periodontal infections in cats and dogs.

Dose and Administration

Follow as instructed by your veterinarian. However typically, the recommended dosage for both dogs and cats once daily orally for a period of 5 to 10 days.

Overdose:

In case of suspected overdose contact your veterinarian or the New Zealand National Poisons Centre at www.poisons.co.nz/animal-helpline/ or phone 0800 869 738.

Contraindications and Precautions

Spiramycin is considered critically important to human and animal health. Improper use of this antibiotic can contribute to antibiotic resistance, and it should not be used as a first line treatment. Use this antibiotic only when other treatments have failed or in cases where culture and sensitivity testing indicate it as the best option. Limit antibiotic use to the minimum period needed to meet the clinical objective. Clinical response should be monitored during treatment.

Potential Side Effects

Although not very common some side effects that could occur include:

  • Vomiting
  • Diarrhoea
  • Anorexia
  • Weakness
  • Brown urine colour

It is important to contact your veterinarian if any of the above is observed.

Storage and Handling

Store at room temperature in a dry place, protected from light. Keep it in the original packaging and out of reach of children and other pets.
