> **Important:** Give this medication exactly as directed by your veterinarian. Even if your pet appears completely well, continue treating for the full duration prescribed to prevent the infection from returning or becoming resistant. * **Administration:** It is preferable to give this medication on an empty stomach. However, if your pet vomits or loses their appetite after taking it, you can give future doses with a small amount of food. * **Side Effects:** Mild stomach upset (soft stool, occasional vomiting) can occur. * **When to Call the Vet:** Contact your veterinarian immediately if your pet develops severe vomiting, severe diarrhea, or signs of an allergic reaction (such as facial swelling, hives, or severe itching). * **Storage:** If you were given a liquid suspension, keep it in the refrigerator and throw away any unused portion after 14 days.
