Why is it prescribed?
Clarithromycin is used to treat infections caused by susceptible bacteria. This material will be limited to infections of the respiratory tract (e.g. pneumonia, tonsilitis, sinuses, sore throat) and the middle ear.
- Use exactly as prescribed.
- Taro-Clarithromycin tablets can be taken with or without food. If it upsets the stomach, take with food. Take at even intervals around the clock as prescribed (e.g. every 12 hours translates to twice a day) 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 7 to 14 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.
- It is not unusual to experience the more common, unwanted effects with Taro-Clarithromycin tablets (e.g. nausea, diarrhea, etc.). Contact your doctor or pharmacist if they are severe, persist or become bothersome.
- Taro-Clarithromycin tablets 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.

Clarithromycin is an antibiotic. It works by suppressing formation of vital proteins in bacteria, slowing bacterial growth. Clarithromycin does not suppress growth of all types of bacteria, but only those that have a sensitivity to this antibiotic. Infections caused by bacteria that are not sensitive to clarithromycin will not show improvement after taking this medication.
Along with its needed effects, clarithromycin may cause some unwanted or undesirable effects. Generally, clarithromycin is well tolerated and many people will not experience unwanted effects. The frequency and severity of these effects is dependant on many factors including dose, duration of therapy and individual susceptibility. Possible unwanted effects include:
- abnormal taste
- stomach discomfort
- allergy (e.g. hives, itching, rash, difficulty breathing)
- diaper rash
- oral candidiasis (thrush)
- jaundice (yellowing of skin or eyes)
- difficulty breathing
Allergic reactions can occur with clarithromycin use. 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 clarithromycin may need to be stopped and another antibiotic prescribed to treat the new infection.
Diarrhea often develops while taking clarithromycin. 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.
