If so, then I think it might be worth asking your pharmacist for the newly required FDA Medication Guide and the revised pharmaceutical insert dated May-2000.
The FDA-Medwatch adverse event reports contain many reports of various neuro/cardio/nervous system problems.
I am a licensed practicing pharmacist (35 y/o) and took Accutane for close to 2 years when I was around 27 or so. Have both personal and professional experience with the medication. What are your concerns/questions?
