While azithromycin is generally well-tolerated by cats, some side effects can occur. Vomiting is a common reaction, often mild and self-limiting. You may notice your cat experiencing diarrhea or loss of appetite. These usually resolve without intervention.
Less frequently, cats may exhibit lethargy or changes in their behavior. These symptoms warrant closer observation and a possible veterinary consultation. In rare cases, more serious reactions, such as liver problems, can develop. Signs of liver issues include jaundice (yellowing of the skin or whites of the eyes), dark urine, or pale gums.
Allergic reactions are possible, although uncommon. Symptoms range from mild skin irritation to more severe reactions like swelling of the face or difficulty breathing. Immediate veterinary attention is needed if you notice any signs of an allergic reaction.
Remember to always follow your veterinarian’s instructions carefully regarding dosage and duration of treatment. Regular monitoring of your cat is recommended, especially during the initial days of medication. Contact your vet immediately if you observe any unusual or concerning symptoms.
This information is for general knowledge and does not replace professional veterinary advice. Always discuss potential side effects with your veterinarian before administering azithromycin to your cat. They can assess your cat’s individual risk factors and provide personalized guidance.
