Along with its needed effects, azithromycin may cause some unwanted or undesirable effects. Generally, azithromycin is well tolerated and many people will not experience unwanted effects.

Precautions and Warnings for CO Azithromycin® tablets
CO Azithromycin® tablets contains azithromycin
Allergic reactions can occur with azithromycin use. People with a history of allergy, asthma, hay fever or hives seem to be more susceptible to these reactions. The reaction can be immediate and severe. Allergic symptoms include wheezing, hives, itching, swelling, spasms in the throat and breathing tubes, joint and muscle pain, difficulty breathing, fever and skin rashes. Nausea and vomiting are not symptoms of an allergic reaction.
Taking the antibiotic repeatedly or for prolonged periods may result in bacterial or fungal overgrowth which can lead to a second infection. When this occurs, the azithromycin may need to be stopped and another antibiotic prescribed to treat the new infection.
Diarrhea often develops while taking azithromycin. This is sometimes caused by an overgrowth of bacteria in the gut that are not killed by the antibiotic. In severe cases, this may be life threatening and would require treatment with other antibiotics. In mild cases, symptoms disappear shortly after the drug is discontinued.

Try to take the single daily dose at the same time each day with a glass of water. Take CO-Azithromycin® as prescribed until finished. Failure to take the complete course can result in incomplete elimination of the bacteria which can lead to a relapse of the infection. The prescribed course generally lasts a few days longer than symptoms of the infection (e.g. fever). Treatment usually lasts 5 days. If you miss a dose, take it as soon as possible. If it is almost time for your next dose, do not take 2 doses at once (unless you have been instructed to do so). Contact your pharmacist if you are not sure what to do.
CO-Azithromycin® may produce an allergic reaction which can range in severity from a mild rash or itching to a life-threatening reaction. Contact your doctor or pharmacist if you experience rash, itching, fever, difficulty breathing, chest tightness or anything else that alarms you.
It is not unusual to experience the more common, unwanted effects with CO-Azithromycin®(e.g. nausea, diarrhea, etc.). Contact your doctor or pharmacist if they are severe, persist or become bothersome or if you notice any other adverse effects.
