Zyrtec-D and Dry Mouth

For people who take Zyrtec-D, dry mouth is one of the drug's most common side effects. Suggestions that may provide relief include sipping water or sugarless drinks often, using a humidifier at night, and avoiding tobacco. If you continue to experience dry mouth with Zyrtec, ask your healthcare provider about other treatment options.

Zyrtec-D and Dry Mouth: An Overview

Dry mouth is a common side effect of Zyrtec-D® (cetirizine and pseudoephedrine). In clinical studies, up to 3.6 percent of people taking the drug experienced a dry mouth, compared to less than 1 percent of people taking a placebo (a "sugar pill" with no active ingredient).
 

Zyrtec-D and Dry Mouth: Recommendations

If you are taking Zyrtec and dry mouth occurs, there are some things that may provide relief. Some of these suggestions include the following:
 
  • Sip water or sugarless drinks often.
  • Avoid drinks with caffeine, such as coffee, tea, and some sodas. Caffeine can dry out the mouth.
  • Sip water or sugarless drinks during meals. This will make chewing and swallowing easier, as well as improve the taste of food.
  • Avoid tobacco or alcohol because they can dry out the mouth.
  • Use a humidifier at night.
  • Be aware of spicy or salty foods; they may cause pain in a dry mouth.
  • Chew sugarless gum or suck on sugarless hard candy to stimulate saliva flow; cinnamon- or mint-flavored candies are good choices.
     
Either of the components in Zyrtec-D (cetirizine or pseudoephedrine) can cause dry mouth.
 

Zyrtec-D and Dry Mouth: Final Thoughts

If you develop a dry mouth while taking Zyrtec-D and the suggestions in this article do not help, talk with your healthcare provider. He or she may be able to recommend other treatment options, such as artificial saliva. Also, depending on how severe your dry mouth is, your healthcare provider may recommend that you try another allergy medicine.
