Of the rarer side effects seen with Gabitril, dry mouth occurred in up to 1 percent of people taking the drug.

Gabitril and Dry Mouth: An Overview

Dry mouth is one of the possible rare side effects of Gabitril® (tiagabine hydrochloride). In clinical studies, between 1 in 100 and 1 in 1,000 people taking the drug experienced dry mouth.

Gabitril and Dry Mouth: Recommendations

If you are noticing a dry mouth that is possibly due to Gabitril, there are some things that you can do to help. Some of these suggestions include the following:
  • Be aware of spicy or salty foods, because 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.
  • Sip water or sugarless drinks often.
  • Sip water or sugarless drinks during meals. This will make chewing and swallowing easier; it may also improve the taste of food.
  • Avoid drinks with caffeine, such as coffee, tea, and some sodas. Caffeine can dry out the mouth.
  • Don't use tobacco or alcohol, because they dry out the mouth.
  • Use a humidifier at night.

Gabitril and Dry Mouth: Final Thoughts

If you develop dry mouth while taking Gabitril and the suggestions in this article do not help, make sure to 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, he or she may recommend that you adjust your Gabitril dosage or try another epilepsy medication.
