I have taken this drug for a year. I helps with the "got to go" symptoms but I find myself dizzy and forgetful. Can Sanctura do that to someone? ## Yes, Sanctura (Trospium) has been known to cause such issues as side effects, according to FDA reports, along with nausea, urinary retention, blurred vision, and dry skin. However, it would be best to consult your doctor to be certain of what's going on. Depending on the severity of the symptoms, you may need to try a different medication, or these symptoms might be unrelated to it. Are you on any other medications? Ref: Medline Plus
