1/14/2019 Pre Test 1. True or False? Pharmacy Personal do not need to provide patients on Vivitrol with the REMS information about severe injection site reactions. 2. RJ is a 24 year old male taking Levetiracetam for seizures. He presents with a 21 day history of feeling sad most of the time, missing work 4 times because he slept through his alarm and continued to sleep all day, feeling tired, sluggish, not able to concentrate and gaining 10 pounds without trying to. RJs boss gave him a written reprimand which is the first step in documenting a reason to terminate his employment at his company. Which is the best option given the above information: a) Do nothing, RJ does not meet criteria for major depression. b) Start Bupropion – it’s activating and will pep him up. c) Start Sertraline for a major depressive episode, give RJ a 12 week prescription so he doesn’t miss any more work for appointments. d) Refer to PCP for medical evaluation. Pre Test, continued 3. How long should pharmacotherapy be continued after a third episode of major depression? a) 4-9 months after symptoms stabilize. b) 12 months after symptoms stabilize. c) Discontinue as soon as symptoms are reduced 75% d) Indefinitely, possibly life-long. 4. Which of the following best represents an acceptable starting dose of SSRI in an 80 year old patient with normal renal and hepatic function and no drug interactions? a) Sertraline 12.5 mg daily b) Citalopram 40mg daily c) Fluoxetine 20mg daily d) Paroxetine 20mg daily 3
1/14/2019 Board Certification in Psychiatric Pharmacy (BCPP) Board of Pharmacy Specialties Certifies and recertifies 11 different specialties, including psychiatric pharmacy Currently, there are more than 1,000 Board Certified Psychiatric Pharmacists https://www.bpsweb.org/bps-specialties/psychiatric-pharmacy/ College of Psychiatric and Neurologic Pharmacists (cpnp) Provides both the board certification and recertification study materials Annual meeting April 7-10, 2019 Salt Lake City, Utah https://cpnp.org/ Major Depressive Disorder (MDD) Statistics in Alaska Alaska has one of the highest rates of suicide per capita in the country The rate of suicide in the United States was 12.57 suicides per 100,000 people in 2013 By comparison, in 2014, Alaska’s rate was 22.3 suicides per 100,000 people More than 90% of people who die by suicide have depression or another diagnosable, treatable mental or substance abuse disorder, according to the American Association of Suicidology 4
1/14/2019 Diagnostic Criteria MDD DSM-5 Five of more of the following symptoms have been present during the same 2-week period and represent a change from previous functioning; at least one of the symptoms is (1) depressed mood or (2) loss of interest or pleasure Excludes symptoms clearly attributable to another medical condition. 1. Depressed mood most of the day, nearly every day, as indicated by either subjective report (feels sad, empty, hopeless) or observation made by others (appears tearful). (In children and adolescents can be irritable mood). 2. Markedly diminished interest or pleasure in all, or almost all, activities most of the day, nearly every day (as indicated by either subjective account or observation). 3. Significant weight loss when not dieting or weight gain (change of more than 5% of body weight in one month), or decrease or increase in appetite nearly every day (In children, consider failure to make expected weight gain). Diagnostic Criteria MDD DSM-5, continued 4. Insomnia, or hypersomnia nearly every day. 5. Psychomotor agitation or retardation nearly every day (observable by others, not merely subjective feelings or restlessness or being slowed down). 6. Fatigue or loss of energy nearly every day. 7. Feelings of worthlessness or excessive or inappropriate guilt (which may be delusional) nearly every day (not merely self-reproach or guilt about being sick.) 8. Diminished ability to think or concentrate, or indecisiveness, nearly every day (either by subjective account or as observed by others). 9. Recurrent thoughts of death (not fear of dying), recurrent suicidal ideation without a specific plan, or a suicide attempt or a specific plan for committing suicide. 5
1/14/2019 Diagnostic Criteria MDD DSM-5, continued The symptoms cause clinically significant distress or impairment in social, occupational or other important areas of functioning. The episode is not attributable to the physiological effects of a substance or another medical condition. The occurrence of the major depressive episode is not better explained by schizoaffective disorder, schizophrenia, schizophreniform disorder, delusional disorder, or other specified and unspecified schizophrenia spectrum and other psychotic disorders. There has never been a manic episode of hypomanic episode. Classifications of Major Depressive Disorder Severity of Episode – determined by the number and severity of diagnostic criteria met and the degree of functional impairment Mild episodes- 5-6 depressive symptoms and minimal functional impairment Severe episodes – nearly all symptoms present and significant functional impairment Presence of Psychotic Features Episode characterized by delusions or hallucinations (usually auditory) Psychotic features are either mood-congruent or mood incongruent Mood incongruent features indicate worse prognosis In Remission Absence of significant symptoms for at least 2 months Partial remission defined as either continued presence of some symptoms but either full criteria not met OR duration is less than 2 months Chronic - full criteria for a major depressive episode met for a minimum of 2 years 6
1/14/2019 Descriptive Specifiers for MDD With Anxious Features With Mood-Incongruent Psychotic Features With Mixed Features With Catatonia With Melancholic Features With Peripartum onset With Atypical Features With Seasonal Pattern (recurrent With Mood- Congruent Psychotic episode only) Features Recording the Diagnosis Terms are listed in the following order Major Depressive Disorder Single or recurrent episode Severity/psychotic/remission specifiers As many of the specifiers that apply to the current episode Why is this important to know? Helps guide treatment and length of therapy 7
1/14/2019 Signs and Symptoms of Depression SIGECAPS Sleep disturbances Interest (loss of) Guilt (excessive) Energy (changes in) Concentration(impaired) Appetite changes Psychomotor agitation or retardation Suicidal ideations or actions Vague complaints with no identifiable medical cause Rating Scales for MDD Practice Pearl – The rater should pick one and use it consistently. The pharmacist does not need to be the rater, does need to be able to interpret and clinically correlate data Hamilton Depression Rating Scale (HAM-D) – Gold Standard for clinical research Montgomery-Asberg Depression Rating Scale (MADRS) Geriatric Depression Scale (GDS) Children’s Depression Rating Scale-Revised (CDRS-R) Guidelines for Adolescent Preventive Services (GAPS) questionnaire Pediatric Symptom Checklist (PSC) 8
1/14/2019 Reporting personal MDD diagnosis to the Alaska Board of Pharmacy All pharmacists and pharmacy techs must answer the following professional fitness question at time of initial licensure and all subsequent renewal: “Have you experienced or been treated for bipolar disorder, schizophrenia, paranoia, depression, (except for situational or reactive depression), psychotic disorder, or other mental or physical disability? A “yes” answer to this question requires a fit to practice letter from the licensee/applicant’s primary care physician. The fit to practice does not have to disclose specific medications; only the status of the condition and how it affects the ability to safely provide services Clinical Course of Major Depressive Disorder First episode may occur at any age (average onset late 20s) No one size fits all description, symptoms may develop suddenly or over time Median time to recover with adequate treatment is 20 weeks Untreated episodes can last over 6 months Risk of Recurrence 1 prior episode, 50 % will experience another episode 2 prior episodes, 70 % will experience another episode 3 or more prior episodes- at least 90% of people will experience another episode 9
1/14/2019 Suicide Risk The possibility of suicidal behavior exists at all times during major depressive episodes The most consistently described risk factor is a past history of suicide attempts or threats but most completed suicides are NOT preceded by unsuccessful attempts. Risk factors for completed suicide: male, single or living along, prominent feelings of hopelessness. Presence of borderline personality disorder markedly increases risk for future suicide attempts. Suicide Risk Factors: IS PATH WARM? Ideation Substance Abuse Purposelessness Anxiety Trapped (feelings of no way out) Hopelessness Withdrawal Anger Recklessness Mood changes (dramatic) 10
1/14/2019 Resources for Mental Health Crisis Intervention Pharmacy staff are NOT expected to provide crisis intervention counseling unless specially training- stay within your scope of training. Pharmacy staff ARE advised to have the contact information for emergency health recourses available to provide people. http://www.muni.org/departments/health/phip/documents/community%20resource%20list%2 05%2023%2018.pdf http://www.suicide.org/hotlines/alaska-suicide-hotlines.html http://www.alaska211.org/Search.aspx Treatment Guidelines for Major Depressive Disorder https://cpnp.org/guideline/external/depression (lists the major guidelines with links) Baseline evaluation: Obtain the baseline info needed to make a plan which includes but is not limited to: family, medical, social, psychiatric history, previous hospitalizations, previous suicide attempts, previous treatments and response to each, PE and labs to r/o medical causes of depression, interview to identify detailed list of target symptoms and goals of therapy and make a safety plan for appropriate interventions if the patient develops suicidal ideation or behaviors. 11
1/14/2019 Non-Pharmacologic Treatment Options available in Alaska Psychotherapy including Cognitive Behavior Therapy and Interpersonal Therapy. Transcranial Magnetic Stimulation – magnetic coils stimulate regions of the brain involved in mood. Electroconvulsive Therapy Bright Light Therapy (first-line treatment for MDD with seasonal pattern) Expose to 30 minutes of artificial light (2500-10000lux) when waking up each morning, activates retinal cells that connect to the hypothalamus. Phases of MDD Pharmacologic Treatment Acute Phase (antidepressant therapy is started and response is monitored) Continuation Phase (significant improvement in symptoms or full remission) Antidepressant treatment should continue at the same dose as the acute phase for additional 4-9 months. Relapse risk without treatment 20-85% Maintenance Phase (recommended for chronic depressive symptoms or with history of three of more MDD episodes) Duration is indefinite, may be lifelong 12
1/14/2019 General Approach: No one size fits all answer! Baseline eval, medical, family, psychiatric history. Review complete med list including OTC, herbal and illicit substances. Perform baseline labs to r/o other causes of depression, r/o other psychiatric disorders (bipolar disorder), make a plan to address target symptoms, goals of therapy and a safety plan for development of suicidal thoughts. Initial treatment can be with medications, psychotherapy or a combination of both. First line therapy SSRI, SNRI, Bupropion or Mirtazapine Assessment of Antidepressant Pharmacotherapy During Acute Phase: Weeks 1-4 13
1/14/2019 Assessment of Antidepressant Pharmacotherapy During Acute Phase: Weeks 4-8 Choosing pharmacologic agent for acute phase of MDD treatment Factors to Consider: Prior response (prior family response if applicable) Patient preference (tolerability and side effect profile) Dosing parameters Co-morbidities/organ system function Potential drug/drug and drug/disease interactions Cost (insurance coverage) 14

Desvenlafaxine Starting & Usual 50mg/day Drug interactions: minor substrate of CYP3A4, induces 3A4 (weak) Causes dizziness, insomnia, diaphoresis, nausea, dry mouth Duloxetine Starting 60mg/day, Usual 60-120mg/day Weak-moderate inhibitor of CYP2D6 (increases TCA and other 2D6 substrates), Substrate of 2D6, increased concentrations with 2D6 inhibitors (paroxetine, fluoxetine, bupropion), increased risk of bleeding with NSAIDS, antiplatelet and anticoagulants Causes dizziness (take at night) or insomnia(take in the morning), GI NV (take with food & at night), sexual disfunction (may switch or augment or use PDE5 inhibitor) 16
1/14/2019 Dopamine Norepinephrine Reuptake Inhibitor Bupropion Starting 150mg/day, Usual 300-450mg/day Causes Dry mouth, sweating, nervousness, tremor, and a dose dependent increased risk for seizures Drug interactions: metabolized by CYP2B6 Lower risk of sexual dysfunction than other antidepressants Contraindications: seizure disorder, bulimia or anorexia, abrupt discontinuation of alcohol or sedatives, use of MAOI therapy, including linezolid, within 14 days Serotonin Modulators Trazodone Starting 150mg/day, Usual 150-600mg/day MOA: weak inhibition of 5-HT and NE reuptake, weak alpha-1 antagonist, serotonin 5HT2 antagonist, histamine antagonist Causes orthostatic hypotension (move slowly when changing position), Nausea (take with food), headache, dizziness and somnolence (dose at night), risk of priapism Contraindicated with use of MAOI, including Linezolid, within 14 days Nefazodone Starting 50mg/day, Usual 150-300mg/day 17
1/14/2019 Norepinephrine-Serotonin Modulator Mirtazapine Starting 15mg/day, Usual 15-45mg/day MOA: Increases the synaptic concentration of serotonin and norepinephrine through presynaptic alpha- 2 antagonism. Serotonin 5 HT2 and 5 HT3 receptor antagonist Causes sedation (take at bedtime), increased appetite and weight gain, hypertriglyceridemia, dry mouth Contraindicated use of a monoamine oxidase inhibitor (MAOI), including Linezolid, within 14 days Tricyclic Antidepressants (TCA) MOA: inhibit presynaptic 5-HT and NE reuptake by inhibition of the 5-HT and NE transporters in the neurons of the CNS, increases 5-HT and NE in the respective synaptic clefts Major Side Effects: weight gain, sedation (take at bedtime), mania (rare, stop and evaluate for bipolar disorder), anticholinergic supportively manage blurred vision, drug mouth, constipation, stop and change agent for cognitive impairment, delirium, cardiotoxicity (V tach, heart block is primary manifestation of OD), orthostatic hypotension (slowly change positions), tachycardia (change agent) Contraindications: use of MAOI therapy, including Linezolid, within 14 days, recent myocardial infarction MANY drug interactions! 18

Amitriptyline Starting 25-50mg/day, Usual 100-300mg/day Nortriptyline Starting 25mg/day, Usual 50-200mg/day Active metabolite of amitriptyline T : tonic-clonic seizures upon withdrawal C : cardiac problems such as QT interval prolongation A : anti-cholinergic effects Monoamine Oxidase Inhibitors (MAOI) MOA: potent, irreversible inhibitor of monoamine oxidase (MAO). Through blockade of this enzyme levels of norepinephrine, serotonin, and dopamine are increased in the synapse This enzyme lives in the brain, but also in the liver and the gut. In these other areas, MAO catalyzes oxidative deamination of drugs and potentially toxic substances such as tyramine. This leads to many drug and food interactions Tyramine rich foods in combo with a MAOI can cause Hypertensive Crisis Very high risk for drug interactions Linezolid is an oxazolidinone antibiotic that causes mild reversible nonselective inhibition of monoamine oxidase 19
1/14/2019 Augmentation Agents for Major Depression Lithium Second Generation Antipsychotics Response to Treatment Definition of response: 50% reduction in symptoms Nearly 2/3 of people don’t achieve remission with initial pharmacotherapy. Possible reasons for non-response: Comorbid disorders including substance abuse Inadequate dose or duration of medication Incorrect diagnosis Non-adherence to treatment (potentially from adverse effects) Unaddressed psychosocial stressors or psychologic issues. After these are addressed can consider options on next slide. 20
1/14/2019 Options for Partial Response or Non- Response to treatment Switching Often considered if little or no symptoms improvement despite adequate dose for 4-8 weeks. No studies have demonstrated clear benefit of switching to an antidepressant within the same class or to an agent with a different mechanism of action. Tapering may be required to minimize withdrawal symptoms Cross Taper Dose of current antidepressant is gradually reduced while the new medication is initiated and dose titrated , usually over 1-2 weeks Direct Switch Current antidepressant is stopped, new antidepressant started Options for Partial Response or Non- Response to Treatment, continued Augmentation Addition of second antidepressant or other medication with a different mechanism of action to existing antidepressant treatment regime (don’t augment an SSRI with an SNRI or vise versa) Considered if there is a partial response to treatment after 4-8 weeks. 21
1/14/2019 Length of Therapy No one size fits all; as a general guideline: Treatment should continue at the same dosage as required in the acute phase of an additional 4 to nine months for first and second episodes of Major Depression then individual plan for continuation/discontinuation reassessed. Maintenance therapy is recommended with a history of 3 or more episodes of major depression indefinitely and may be life long. Rural Alaska Treatment Considerations Rapid drug discontinuation can both unmask symptoms and lead to antidepressant discontinuation syndrome. People residing in rural areas should request refills of medications 14 days in advance (pharmacy can keep request until date insurance will reimburse) Paroxetine in particular is associated with significant withdrawal syndrome and should not be abruptly stopped. One strategy to manage delays is to cut appropriate tablets (not SR) into ½ or ¼ and take an increment of the dose to avoid abruptly running out. Fluoxetine capsules can be mixed with water and ½ or ¼ of the mixture taken (refrigerate remainder). Pharmacies consider keeping back up supplies of SSRIs in clinics both for initiation of treatment and as emergency medication supplies if replacement is delayed. 22
1/14/2019 FDA Risk Evaluation and Mitigation Strategies (REMS) In 2007, a new law that gave FDA many new authorities and responsibilities to enhance drug safety was enacted. It's called the Food and Drug Administration Amendments Act- sometimes called "FDAAA"- and one of its provisions gave FDA the authority to require a Risk Evaluation and Mitigation Strategy-(REMS) from manufacturers to ensure that the benefits of a drug or biological product outweigh its risks. A REMs may be required by the FDA as part of the approval of a new product, or for an approved product when new safety information arises. Essentially, a REMS is a safety strategy to manage a known or potential serious risk associated with a medicine and to enable patients to have continued access to such medicines by managing their safe use. Since medicines are very different from each other, each REMS for each medicine is also different. This presentation discussed REMS and how they are used to help ensure that the benefits of certain medicines continue to outweigh their risks. Why do pharmacy personal need to know about REMS? A Risk Evaluation and Mitigation Strategy (REMS) is a drug safety program that the U.S. Food and Drug Administration (FDA) can require for certain medications with serious safety concerns to help ensure the benefits of the medication outweigh its risks. REMS are designed to reinforce medication use behaviors and actions that support the safe use of that medication. While all medications have labeling that informs health care stakeholders about medication risks, only a few medications require a REMS. REMS are designed to help reduce the occurrence and/or severity of certain serious risks, by informing and/or supporting the execution of the safe use conditions described in the medication's FDA-approved prescribing information. REMS are not designed to mitigate all the adverse events of a medication, these are communicated to health care providers in the medication’s prescribing information. Rather, REMS focus on preventing, monitoring and/or managing a specific serious risk by informing, educating and/or reinforcing actions to reduce the frequency and/or severity of the event. 23
1/14/2019 REMS for Pharmacy Staff - not business as usual! Extra required steps for medications with REMS https://www.fda.gov/Drugs/DrugSafety/REMS/ucm592662.htm Requirements vary for individual REMS and practice settings but may include: Certification process for the pharmacy or healthcare setting (identify authorized representative) Staff training Verify safe use conditions (verifying required lab monitoring is done or patient or prescriber is enrolled in REMS) Counsel patients and or provide educational materials or a medication guide Medication guides are part of labeling, only a small number of medication guides are included as part or REMS The medication may have special ordering requirements such as obtained through a specific supplier Current REMS – 76 entries https://www.accessdata.fda.gov/scripts/cder/rems/index.cfm Examples (not inclusive) Buprenorphine Transmucosal Products for Opioid Dependence (BTOD) Clozapine Naltrexone Opioid Analgesic REMS Sodium Oxybate Suboxone/Subutex 24
1/14/2019 Pregnancy Patient Resources with links to other resources: Pregnancy exposure registries: https://www.fda.gov/scienceresearch/specialtopics/womenshealthresearch/ucm134848.htm CDC Pregnancy Resources: https://www.cdc.gov/pregnancy/index.html https://www.cdc.gov/pregnancy/meds/treatingfortwo/index.html https://mothertobaby.org/fact-sheets/paroxetine-paxil-pregnancy/ Randomized, double blinded, placebo controlled trials are not conducted on pregnant women so pregnancy registries are an important source of safety information. Pregnancy data is primarily obtained from retrospective database studies or prospective cohort studies. Antidepressants in Pregnancy Risks are no clearly defined. Generally accepted principles: Persistent neonatal pulmonary hypertension of the newborn has been associated with SSRI use, especially during the third trimester, though data is inconclusive. Paroxetine is associated with septal wall defects and as the heart is being formed in the first trimester, paroxetine is NOT recommended for women trying to conceive or in the first trimester of pregnancy. Monoamine Oxidase Inhibitors demonstrated teratogenicity in animal studies St. John’s Work not recommended in pregnancy, conflicting evidence about increased uterine tonicity in animal studies. 25
1/14/2019 Antidepressants in pregnancy Antidepressant therapy is generally recommended for pregnancy patients with moderate to severe symptoms or if h/o recurrent, severe depression. Psychotherapy (CBT or IPT) is recommended for mild to moderate depression. Single medication at a higher dose if favored over polypharmacy, the lowest effective dose should be used. Medication selection is based on history of efficacy, prior antidepressant exposure during pregnancy and available safety information. Sertraline is generally considered the first-line agent in pregnancy, reassuring data for citalopram,, escitalopram, early exposure to paroxetine or fluoxetine may increase risk of some birth defects Consider tapering SSRI near delivery to minimize neonatal withdrawal and restart after birth to decrease postpartum depression. Antidepressants in Lactation Breastfeeding Resources: https://toxnet.nlm.nih.gov/newtoxnet/lactmed.htm (contains link to other breastfeeding resources) Risk of untreated post-partum depression/risk of infant exposure to breast milk. Based on small studies, Sertraline and Paroxetine at the lowest effective dose preferred because of non-detectable serum levels in infants. Newer antidepressants lack data, use only if demonstrated efficacy in past episodes is clear and no contraindications exist. Clinical utility of discarding breast milk obtained at Tmax has NOT BEEN ESTABLISHED 26
1/14/2019 Pediatrics CDC Resources https://www.cdc.gov/childrensmentalhealth/depression.html http://pediatrics.aappublications.org/content/pediatrics/141/3/e20174081.full.pdf Research by the American Academy of Pediatrics shows that only 50% of adolescents with depression are diagnosed before reaching adulthood. In primary care (PC), as many as 2 in 3 youth with depression are not identified by their PC providers and fail to receive any kind of care.Even when diagnosed by PC providers, only half of these patients are treated appropriately. Pharmacotherapy in Pediatrics Pharmacotherapy should be reserved for children and adolescents who meet criteria for moderate to severe major depression, persistent depressive disorder (dysthymia), or depressive symptoms with functional impairment, as well as nonresponse to psychotherapy. Same diagnostic criteria as adult patients, however, may use different rating scale Prior to starting antidepressants, clinicians should educate patients and families about depression, including its symptoms and available treatments. Clinicians should also discuss the benefits and side effects of pharmacotherapy, the United States Food and Drug Administration boxed warning about suicidal ideation and behavior, and risks of untreated depression. For children and adolescents, medications are generally started at approximately one-half the usual adult dose 27
1/14/2019 Antidepressants in Pediatrics First line generally Fluoxetine Has the most consistent, high quality evidence FDA approved for MDD 8-18 years old Second line Sertraline, Escitalopram, or Citalopram Escitalopram FDA approved for MDD 12-17 years old Venlafaxine Comparable results to SSRIs Third Line Bupropion or Duloxetine Typically after failure of Fluoxetine, another SSRI, and venlafaxine Mirtazapine found no advantage over placebo Tricyclics are rarely used to treat pediatric depression due to side effects and lack of evidence. If used, obtain BP, pulse, and EKG: at baseline, when therapeutic dose reached, when dose is changed Antidepressants in Pediatrics An adequate antidepressant trial in children and adolescents lasts 6 to 12 weeks, which includes the time to titrate from the starting dose to the minimum therapeutic dose, as well as 4 to 6 weeks at the minimum therapeutic dose For depressed patients who improve but do not remit at the minimum therapeutic dose, a dose increase within the therapeutic range is indicated, provided the drug is tolerated. If improvement is insufficient after 4 weeks at the maximum therapeutic dose, switching medications is indicated Clinicians and families should monitor patients who are treated with pharmacotherapy by assessing symptoms, including suicidal and homicidal ideation and behavior, anxiety and panic attacks, agitation, irritability or hostility, impulsivity, akathisia (ie, restlessness and inability to sit down), and insomnia 28
1/14/2019 Antidepressants in Advanced Age https://www.cdc.gov/aging/depression/index.html (contains link to other resources) Initiate at lower dose and titrate more slowly than young, healthy adults. Choice of antidepressant includes consideration of organ system function, minimizing drug interactions and side effects. Monotherapy preferred over polypharmacy , switching preferred to augmentation. SSRIs are treatment of choice with careful monitoring for DIADH and hyponatremia. Post Test 1. True or False? Pharmacy Personal do not need to provide patients on Vivitrol with the REMS information about severe injection site reactions. 2. RJ is a 24 year old male taking Levetiracetam for seizures. He presents with a 21 day history of feeling sad most of the time, missing work 4 times because he slept through his alarm and continued to sleep all day, feeling tired, sluggish, not able to concentrate and gaining 10 pounds without trying to. RJs boss gave him a written reprimand which is the first step in documenting a reason to terminate his employment at his company. Which is the best option given the above information: a) Do nothing, RJ does not meet criteria for major depression. b) Start Bupropion – it’s activating and will pep him up. c) Start Sertraline for a major depressive episode, give RJ a 12 week prescription so he doesn’t miss any more work for appointments. d) Refer to PCP for medical evaluation. 29
