Dosing Information for Tablet:

It is important to follow your Veterinarian's prescription instructions for your pet.

In dogs, the usual dosage is 2.5 to 5 mg per pound 5 to 10 mg/kg orally once daily for up to 7 days

In cats, the usual dosage is 2.5 to 7.5 mg per pound 5 to 15 mg/kg orally every 12 to 24 hours for up to 7 days

The duration of administration depends on the condition being treated, response to the medication and the development of any adverse effects.
Be certain to complete the prescription unless specifically directed by your veterinarian. Even if your pet feels better, the entire treatment plan should be completed to prevent relapse.

Dosing Informaton for Liquid:


Tap Bottle to loosen powder. Add listed amount of water to the bottle. After mixing, use within 10 days. Discard after full dosing is completed. After mixing, store suspension at 41 to 86 degrees F. Oversized bottle provides extra space for shaking.


For liquids, shake well before accurately measuring the dose. If using the suspension, give on empty stomach. Give medication as directed by your veterinarian. This medication is usually given once or twice daily. Read and follow the label carefully. Give the exact amount prescribed and only as often as directed. Missed doses reduce the effectiveness of therapy. Give this medication for as long as your veterinarian directs. Finish the entire course of treatment. Ideally, give the medication at the same time daily.

Uses of Azithromycin:

Treatment of infections caused by susceptible microorganisms: Dermatological infections Respiratory tract infections Urogenital infections Otitis media

Precautions and Side Effects:

Azithromycin should not be used in animals with known hypersensitivity or allergy to it or other macrolide antibiotics. In addition, it should be used with great caution if at all when there is preexisting liver disease. Gastrointestinal side effects may include vomiting, diarrhea, or abdominal pain. Angioedema and cholestatic jaundice have been reported rarely in treated humans. Cardiac arrhythmias, including ventricular tachycardia, may be precipitated by azithromycin. Renal dysfunction, including interstitial nephritis and acute renal failure, may occur secondary to azithromycin treatment and liver function may be affected.

Drug Interactions:

Azithromycin may elevate serum digoxin levels. When ergotamine or dihydroergotamine are concurrently administered with azithromycin ergot toxicity may occur. Azithromycin causes a decrease in the clearance of triazolam and thus an increase in its pharmacologic effects Pimozide is contraindicated in patients receiving azithromycin, and vice versa death may result Animals being treated with cisapride should not be given azithromycin or other macrolide antibiotic Drugs metabolized by cytochrome P450 e.g. carbamazepine, terfenadine, cyclosporine, hexobarbital, and phenytoin will have their serum levels elevated by azithromycin Oral antacids reduce the absorption of azithromycin
