Hi Heather and Kaleb,   Thank you for your question. Dry mouth is actually a pretty common side effect, occurring in up to 20% of the people who take Strattera. Other common side effects include headache, insomnia, upset stomach, and decreased appetite. You can read more about Strattera by clicking here. If the dry mouth becomes too bothersome, you can check with your doctor about switching to another medication. However, keep in mind that all medications have potential side effects, and you have to weigh the benefits of the medication against the side effects that you may experience. I hope this helps!   Best of luck, Casey
