Oxybutynin 20mg daily is drying out my mouth, anything i can use to help this?

No: May increase fluid intake and discuss with your doctor if lower dose could be used

Try another med: Oxybutinin is one of the oldest anticholinergic med which is relatively non selective . I would recommend you try some of the newer meds that are more bladder selective such as Vesicare, (solifenacin) Toviaz, or Myrbetriq just to name a few. These have much less dry mouth side effects than oxybutinin
