Chlorhexidine may have a bitter aftertaste. Do not rinse your mouth with water immediately after using chlorhexidine, since doing so will increase the bitterness. Rinsing may also decrease the effect of the medicine.
Chlorhexidine may change the way foods taste to you. Sometimes this effect may last up to 4 hours after you use the oral rinse. In most cases, this effect will become less noticeable as you continue to use the medicine. When you stop using chlorhexidine, your taste should return to normal.
Chlorhexidine may cause staining and an increase in tartar (calculus) on your teeth. Brushing with a tartar-control toothpaste and flossing your teeth daily may help reduce this tartar build-up and staining. In addition, you should visit your dentist at least every 6 months to have your teeth cleaned and your gums examined.
If you think that a child weighing 22 pounds (10 kilograms) or less has swallowed more than 4 ounces of the dental rinse, get emergency help at once. In addition, if a child of any age drinks the dental rinse and has symptoms of alcohol intoxication, such as slurred speech, sleepiness, or a staggering or stumbling walk, get emergency help at once.
