Pharmacist Learning Objectives




Discuss abnormalities of the mental status exam that may
warrant treatment with a psychiatric medication.
Review clinical pearls and counseling points for
antipsychotics, antidepressants, mood stabilizers, sedativehypnotics, and anxiolytics.
Identify barriers to effective medication education within
the psychiatric patient population.
Describe techniques to enhance communication and
patient interviewing skills.
Assessment Question #1
During a routine clinic appointment, a patient presents to
you with very eccentric attire, talking extremely fast, and
frequent. They begin to tell you about their ability to
communicate with the deceased and aspirations to become
a physician, senator, and preacher. They describe “not
sleeping for days.” This patient is displaying symptoms that
best represent:
1.
2.
3.
4.
Schizophrenia
Mania
Depression
Anxiety
Assessment Question #2
Assessment Question #3
You dispense a prescription for asenapine (Saphris®) to a
patient taking it for the first time. It is important to counsel
the patient on which of the following?
While working at the local independent pharmacy, you
receive a phone call from the town physician. He is
requesting a recommendation for a non-addictive sleep aid
for his patient that is depressed. The patient has a history
of alcohol dependence and he would like to prescribe
something that is not a controlled substance. It would be
appropriate for you to suggest:
1.
2.
3.
4.
This medication must be placed under the tongue to dissolve
sublingually
It is necessary to take this medication with at least a 350
calorie meal
This medication commonly makes people feel restless, let
your prescriber know if you start to feel anxious
You will need to get your blood drawn weekly for the first 6
months of treatment

Assessment Question #4
Abnormalities of Mental Status
It is important to recognize that an individual with a severe
and persistent mental illness is faced with many barriers
that may prevent successful treatment. A barrier to
treatment adherence that you (the pharmacist) can directly
impact daily would be:

1.
2.
3.
4.
Co-occurring alcohol dependence
Negative stigma associated with mental illnesses
Paranoia and auditory hallucinations
Homelessness and poverty
Abnormalities of Mental Status
Appearance:
 Poor grooming, mismatched dress, hygiene, unshaven,
poor dentition
Behavior:
 Difficult to engage, psychomotor slowed, poor eye
contact, stooped posture, poor impulse control, abnormal
movements (tremor, tics)
Speech:
 Poverty of speech, neologisms, difficulty with word finding,
clanging

Sara J. is a 45 year old female wearing mismatched
clothes, malodorous, presenting to the pharmacy counter
window. She is demanding to speak to the pharmacist. “I
can’t take this Zyprexa anymore….I’ve gained too much
weight!”
As you observe her walking up & down the store aisle,
she is talking to herself.



Barriers in Medication Education

Stigmatized perception of mental illness
Public perceptions of mental illnesses:








71%- due to emotional weakness
65%- caused by bad parenting
45%- victim’s fault; can will it away
43%- incurable
35%- consequence of sinful behavior
10%- has a biological basis; involves the brain



Poverty-related factors
Complex dosing regimens
Internet resources
Poor disease insight
Co-occurring substance use
Active symptoms:
Psychosis (paranoia)
Amotivation (negative symptoms; depression)
Cognitive dysfunctions (memory deficits)





No consensus on treatment recommendations among
prescribers
Pharmacist attitude & behavior (poor communication)
Stahl SM, Essential Psychopharmacology:
neuroscientific basis and practical applications, 2000.
Assessing Adherence & Building Rapport

Important questions to ask:





Tell me how your medications are helpful to you?
Do you think you need all of the medications you are taking?
How do your medications make you feel?
How often do you forget to take your medications?
When you feel better, do you sometimes stop taking your
medication?
Improving Patient Communication


Let the patient discuss their concerns first
Listen to patient’s beliefs and attitudes




Withhold the urge to contradict or “correct” patient beliefs
The patient’s subjective beliefs rather than objective medical
reality ultimately influence behavior
Be sensitive to cultural beliefs
Patients are more likely to be adherent when they experience
the clinician as competent, supportive, optimistic, and
encouraging
Improving Patient Communication


Psychoeducation
Motivational Interviewing (MI)


Directive, person-centered counseling style for eliciting behavior
change; helping patients to explore & resolve ambivalence
Work within the stages of change




Precontemplation:“there is no problem”
Contemplation:“there may be a problem, I have mixed feelings about it.”
Determination / preparation:“there is a problem & I want to change.”
Action → Maintenance
Core features of MI


Express Empathy

Develop Discrepancy

Avoid Argumentation

Roll with Resistance
