Before you begin using a medication, be sure to inform your doctor of any medical conditions or Allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use Dom Clarithromycin.
Abnormal heart rhythm: Clarithromycin may cause a heart rhythm problem called QT prolongation. If you have a history of QT prolongation, a medical condition associated with QT prolongation, or are taking certain medications (e.g., Amiodarone, Sotalol), discuss with your doctor how Dom Clarithromycin may affect your medical condition, how your medical condition may affect the dosing and effectiveness of Dom Clarithromycin, and whether any special monitoring is needed.
Allergy: If you have had some form of allergy to erythromycin or azithromycin, you may be more likely to have an allergic reaction to Dom Clarithromycin. If you develop symptoms of an allergic reaction such as a rash, contact your doctor. If you develop hives; difficulty breathing; or swelling of the face, mouth, throat, or tongue, stop taking Dom Clarithromycin and get immediate medical attention.
Bacterial resistance: Misuse of an antibiotic such as clarithromycin may lead to the growth of resistant bacteria that will not be killed by the antibiotic. If this happens, the antibiotic may not work for you in the future. Although you may begin to feel better when you first start taking clarithromycin, you need to take all of the medication, exactly as prescribed by your doctor, to finish ridding your body of the infection and to prevent resistant bacteria from taking hold. Do not take clarithromycin or other antibiotics to treat a viral infection such as The Common Cold; antibiotics do not kill viruses, and using them to treat viral infections can lead to the growth of resistant bacteria.
Diarrhea: As with other antibiotics, clarithromycin is associated with a serious infection called Clostridium difficile-associated diarrhea, caused by the bacteria C. difficile. This can occur as late as 2 months after your last dose of Dom Clarithromycin.
If you have loose, watery bowel movements especially if they are green, foul-smelling, or bloody and accompanied by Fever, either during or after taking clarithromycin, get medical attention as soon as possible.

Kidney function: Kidney Disease or reduced kidney function may cause Dom Clarithromycin to build up in the body, causing side effects. If you have reduced kidney function, discuss with your doctor how Dom Clarithromycin may affect your medical condition, how your medical condition may affect the dosing and effectiveness of Dom Clarithromycin, and whether any special monitoring is needed.
Liver problems: Liver disease or reduced liver function may cause Dom Clarithromycin to build up in the body, causing side effects. If you have reduced liver function, discuss with your doctor how Dom Clarithromycin may affect your medical condition, how your medical condition may affect the dosing and effectiveness of Dom Clarithromycin, and whether any special monitoring is needed. Dom Clarithromycin should not be used by people with severe liver problems.
