The Basics of Safely Prescribing SSRIs/SNRIs & Other Medications for Depression and Anxiety Symptoms with Job Corps Students David Kraft, MD, MPH Boston Regional Mental Health Specialist

Outline Overview of psychotropic drugs Diagnostic categories (DSM-5) Clinical indications (e.g., starter doses, follow-up doses, etc.) Black box warnings Side effects Indications and strategies to stop medications Ongoing frequency of follow-up Drug interactions

Overview Most frequent mental health problems in Job Corps where medications are prescribed are depression and anxiety issues. The next most common problem is ADHD at many centers. Most frequent psychoactive medications with Job Corps youth are antidepressants, which are also good for anxiety issues.

Overview (continued) Fewer students will require other psychotropic medications, such as are used with Bipolar Disorder, Schizophrenia, and other disorders –Usually such students will arrive already on these medications, so the Center Physician may only be asked to continue the prescriptions –Many Job Corps centers are not located near a psychiatric clinic or provider who can prescribe for the student while on center

Diagnostic Symptoms of Depression (DSM-5) Criteria for Depression (5 of 9 symptoms) –Depressed mood nearly every day –Decreased interest/pleasure in activities –Significant change in weight (not trying +/-) –Insomnia or hypersomnia most days –Psychomotor agitation or retardation –Fatigue/loss of energy most every day –Feelings worthlessness/excessive guilt –Reduced ability to think or concentrate –Recurrent thoughts of death/suicidality

Depression Symptoms (continued) Symptoms cause clinically significant distress or impairment Episodes not due to physiological effects of a substance or another medical condition Other Depressive Diagnoses –Persistent Depressive Disorder (Dysthymia) –Premenstrual Dysphoric Disorder –Substance/Medication Induced Depression

Diagnostic Symptoms of General Anxiety Disorders Worry about specific situation for at least 6 months, plus 3/6 symptoms: –Restlessness, all keyed up –Being easily fatigued –Trouble concentrating or mind goes blank –Irritability –Muscle tension –Sleep disturbance Treat with Psychotherapy plus Meds –Cognitive Behavioral Therapy, Relaxation, Rebreathing, Meditation

Diagnostic Symptoms of Other Anxiety Disorders Specific Phobia and Social Phobia Panic Disorder Agoraphobia (marked fear/anxiety about not being able to avoid dangers) Obsessive Compulsive Disorder and Related Disorders Post-Traumatic & Acute Stress Disorder Eating Disorders

General Principles Most medications take 1-2 weeks to work effectively (absorbed in GI tract, then transferred to cerebrospinal fluid in brain to begin working) Side-effects often noticed shortly after taking medication (mainly in blood in sufficient levels) Some side-effects can be useful, e.g. sedation if someone has trouble getting to sleep Most antidepressants are good for treating anxiety disorders as well

General Principles in Job Corps Most students on medications when they arrive will want to stay on the medication during their training. Consult with the Center Mental Health Consultant (CMHC) when a student seems to need an adjustment in one of his/her medications. Major changes in medication should be done during vacations, if possible.

Clinical Indications Major Depression (single and recurrent types, not Bipolar) Severe Anxiety Disorders, e.g. Obsessive Compulsive Disorder Sleep hygiene, not complicated, though may need to add sedating antidepressant (e.g. trazodone) and follow

Other Common Agents Older agents (e.g., tricyclic antidepressants & MAOIs) not used without consultation with Specialist

Black Box Warnings Increased risk of suicidal thinking and behavior in children, adolescents, and young adults taking antidepressants Monitor for worsening and emergence of suicidal thoughts and behaviors, especially during the first two weeks of treatment

Black Box Warnings Antidepressants increased the risk compared to placebo of suicidal thinking and behavior (suicidality) in children, adolescents, and young adults in short-term studies of major depressive disorder (MDD) and other psychiatric disorders. –Risk limited to persons under 24 years –Worse in first days of treatment in most studies –May take at least 1 month to work –Suicidality NOT the same as suicide

Indications to Stop Medications Unacceptable side effects after 5 days. (Usually, mild sedation or activation disappears in a few days). Occurrence of mania/hypomanic symptoms when not already on Mood Stabilizers (lithium, divalproex, carbamazepine). Staff or other students complain about risky behaviors, different from behavior before medication. Report of suicidal ideas or plans (probably needs MSWR or hospitalization if concern about suicide).

Stopping Medications When someone stops their psychotropic medications, it usually takes at least 5 days to get out of their system. –Most meds need to be tapered, to avoid withdrawal symptoms. –Exceptions to these general rules include stimulants and “benzos” (benzodiazepines), which work quickly and can usually be stopped quickly, though tapering is better.

Drug Interactions SSRIs/SNRIs are generally safe and effective after at least 2 weeks Starting dose often all that is needed A few students treated with TCAs will need added side effect meds.* Students on MAOIs need careful monitoring to avoid dietary side effects.* Most other medications can be safely taken with usual SSRI/SNRI treatment.. *Consultation indicated.

Ongoing Follow-up Students should be monitored by the center physician (CP), CMHC, and health and wellness staff. If current medicine is not working –CP may consult with CMHC and adjust meds –Refer for consult with psychiatrist in community, if available –Refer back to original prescriber via leave or during breaks –MSWR should be considered if student is having acute symptoms interfering with participation in program
