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 this medication.
Gingivitis and periodontitis: People who have both gingivitis and periodontitis need to know that clearing up the inflammation of the gums from gingivitis may not be an indicator that the periodontitis has also been cleared up. You should continue your periodontitis treatment as prescribed by your dentist.
Staining of teeth: Chlorhexidine gluconate oral rinse can cause staining of the surface of teeth, fillings, and the tongue if used for a long time or in people who may have higher amounts of plaque. The staining does not affect the teeth and can be removed from most tooth surfaces by your dentist. People who have exposed root surfaces or fillings in the front teeth with rough surfaces may have permanent staining as it is more difficult to remove stains from these areas.
Taste changes: Some people using chlorhexidine gluconate may find a change in taste. In rare cases this may become permanent.
Pregnancy: It is not known if chlorhexidine gluconate passes from mother to fetus during pregnancy. This medication should not be used during pregnancy unless the benefits outweigh the risks. If you become pregnant while taking this medication, contact your doctor immediately.
Breast-feeding: It is not known if chlorhexidine gluconate passes into breast milk. If you are a breast-feeding mother and are taking this medication, it may affect your baby. Talk to your doctor about whether you should continue breast-feeding.
Children: The safety and effectiveness of using this medication have not been established for children.
