Can midodrine cause dry mouth? i wake up in the morning with dry mouth and sometimes have it during the day. i am also in lamictal and pepcid. can any of these medications cause dry mouth and if so what can i do about this?

Yes: Both Midodrine and Lamictal can cause symptoms of dry mouth. If it is worse in the morning, it may be that you are mouth breather at night, especially if you snore, and using a humidifier or mask on your face may help. If caused by allergies, a steroid nasal spray is especially helpful to decrease nasal congestion. Sip water throughout the day. Biotene makes a moisturizing mouth spray.

Yes: Midodrine, Lamictal, and Pepcid each have dry mouth listed as side effects, although it appears to most commonly occur with Lamictal. Drinking more water throughout the day or chewing on sugar-free gum or candies may help with dry mouth, but it may be difficult to identify which of the three, if any, is causing it.
