What do you think about going up to 30mg on Lexapro?

Just a comment that may explain your meds for a higher dosage. My doc gave a DNA test to me to show how certain drugs are best and not so best. I metabolize Lexapro more quickly, thus, the dosage of 30mg per night. Ask your therapist if this test could be made available to you.
This test will give you lists of many classifications for you and your doctor to consider.

Hi, Allyson!
25-30mg/day would be prescribed off-label but anxiety disorders are more difficult to treat and slower to respond to antidepressant/anxiolytics. Your doctor has probably determined that the "recommended" dose isn't enough to treat you.
Worst case scenario you may have some new or recurring side effects which is common after a dosage increase but since you already have the medication in your system they would probably be mild and not last long. Plus you are increasing the dose slowly.
If this doesn't work well the options might be an add-on medication like Abilify or Rexulti or switching to a different medication.

PS, if you aren't already you might consider therapy especially CBT (cognitive behavioural therapy) to help you learn ways to help you control your symptoms. You would also address stressors and triggers before the anxiety kicks in.
