What is Rilexine?

Rilexine contains Cephalexin as the main active ingredient which functions as an antibiotic to treat various infections in dogs, including skin infections.

How does it work?

The main ingredient cephalexin is part of the cephalosporins class of antibiotics. It works by disrupting the production of bacterial cell walls, effectively killing the bacteria. However, it is ineffective against viruses, fungi, and parasites. It's important to use Rilexine® as directed by a veterinarian, as misuse can lead to antibiotic-resistant bacteria.

Dose and Administration

The dosage of cephalexin is typically based on your pet's weight and the type of infection. Always follow your veterinarian’s instructions precisely. Rilexine® can be administered with or without food, though giving it with food might reduce digestive upset. If you miss a dose, administer it as soon as you remember, unless it's nearly time for the next dose. In that case, skip the missed dose and continue with the regular schedule. Do not give double doses.

Overdose:

Symptoms of an overdose may include severe vomiting, diarrhoea, excessive drooling, and watering of the eyes. If you suspect an overdose, contact your veterinarian or the New Zealand National Poisons Centre (www.poisons.co.nz/animal-helpline/ or 0800 869 738).

Contraindications and Precautions

Cephalexin is contraindicated in dogs with known allergy or hypersensitivity to cephalosporins and penicillins.

Potential Side Effects

The most common side effect is digestive upset (including diarrhoea, vomiting and decreased appetite). However decreased energy, itching, increased thirst and drowsiness can also occur. Although very rare, allergic reactions can occur. Signs can include:

  • Skin rashes
  • Hives
  • Facial swelling
  • Pale gums
  • Difficulty breathing

If you notice any of these symptoms, seek immediate veterinary care. Do not give to dogs with known allergy to penicillin.

Storage

Store Rilexine® at room temperature, in a tightly sealed container, away from light and moisture. Keep out of reach from children and other pets. The chewable tablets are palatable, so it is essential to store them securely to prevent accidental ingestion by dogs.

Frequently Asked Questions (FAQ)

How long should my pet take Rilexine®?

  • Administer Rilexine® for the duration prescribed by your veterinarian, even if the infection seems to have improved. Stopping treatment early can lead to recurring infections and antibiotic resistance. If symptoms persist, consult your vet.

Can I use Rilexine® prescribed to my pet for another pet at home?

  • Never use medication prescribed for one pet for another. Dosages and treatments are specific to each pet's health condition and needs.

Can Rilexine® treat all bacterial infections in pets?

  • Rilexine® is a broad-spectrum antibiotic, which means it is effective against a wide range of bacteria. However, it may not be suitable for all bacterial infections. The effectiveness of Rilexine® depends on the type of bacteria causing the infection and its sensitivity to the drug. Your veterinarian will be able to determine if Rilexine® is the appropriate treatment for your pet's specific infection.

Conclusion

Rilexine® is a valuable antibiotic for treating certain infections in dogs. Always use it under the guidance of a veterinarian and follow their instructions closely. If you have any concerns or observe adverse reactions in your pet, contact your vet immediately.
