This is Dr. David. I am reviewing your question now and will be with you momentarily.
treatment through the NHS is through his primary care doctor
he needs to get a GP general practitioner doctor to assess his anxiety symptoms
who is prescribing his citalopram?
he may need additional medicaitons like diazepam or clonazepam to help decrease his anxiety symptoms
he also needs to be placed into a program to help him stop his alcohol use as well.
