How would my pcp (family medicine) treat anxiety and/or ptsd

Specialist referral: Hopefully by referral to a specialist for further assessment and treatment. While anxiety is common, ptsd is often more complex. Both benefit from psychotherapy with a psychologist experienced with anxiety disorders though in some cases the pcp or a psychiatrist may prescribe meds in combination with therapy.

Benzo, referral: Usually a pcp will treat anxiety by prescribing a benzodiazepine ("benzo") tranquilizer such as valium or ativan (lorazepam). Ssri antidepressants might be a better choice but aren't as often used by pcps for anxiety. Ptsd can't really be treated in this setting. Referral to a mental health professional is optional (but often a good idea) with anxiety, and necessary for ptsd.

Options: Support & psychotropic medication. Hopefully, also with a nudge toward a psychologist who practices cognitive behavioral therapy.
