SSSRIs

Question 2

disorders, but their use should be short term and only
considered beyond this in treatment-resistant cases
because of problems with side effects and
dependence

Answer 8

• The best evidence is for SSRIs (escitalopram,
paroxetine)
• Consider cognitive-behaviour therapy as it may
reduce relapse rates better than drug treatment
• Monitor efficacy and tolerability regularly during
long term treatment

Question 9

what should you do when GAD treatment fails?

Answer 9

• Consider switching to another evidence-based
treatment after non-response to initial treatment
• Consider switching to venlafaxine or imipramine in
non-responders to acute treatment with an SSRI

to SSRI and SNRI treatment

Question 10

how do you detect and diagnose panic disorder?

Answer 10

• Assess the level of agoraphobic avoidance to help judge the severity of
the condition

pain or shortness of breath

Question 11

what is the acute treatment for panic disorder?

Answer 11

• pharmacological: all SSRIs, some TCAs (clomipramine, imipramine), some
benzodiazepines (alprazolam, clonazepam, diazepam, lorazepam),
venlafaxine, reboxetine

• Consider increasing the dose if there is insufficient response, but there is
only limited evidence for a dose response relationship with SSRIs
• Initial side-effects can be minimized by slowly increasing the dose

Question 12

what should be given in long-term treatment for panic disorder?

Answer 12

In longer-term drug treatment use an approach known to be efficacious
in preventing relapse: first line drug choice is an SSRI , imipramine is a
second-line choice

Question 13

what do you have to rememver when stopping treatment for panic disorder?

for this taper period

what happens when initial treatment for panic disorder fails?

Answer 14

• Consider switching to another evidence-based treatment after non-
response at 12 weeks
• Consider combining evidence-based treatments only when there are no
contraindications
• Consider adding paroxetine or buspirone to psychological treatments
after partial response
• Consider adding paroxetine, whilst continuing with CBT, after initial non-
response
• Consider adding group-CBT in non-responders to pharmacological
approaches
• Consider referral to regional or national specialist services in refractory
patients

patients may benefit from higher doses

Question 18

how should social phobia be treated in the long term?

Answer 18

• In longer-term treatment use an approach known to be efficacious in preventing
relapse : consider an SSRI or CBT first-line : clonazepam may be considered as a
second-line choice

Question 19

what should be done when initial treatment of social phobia fails?

Answer 19

Consider switching to venlafaxine after non-response to acute treatment with an
SSRI
• Consider adding buspirone after partial response to an SSRI
• Consider benzodiazepines in patients who have not responded to other
approaches
• Consider combining evidence-based treatments only when there are no
contraindications
• Consider combining drug treatment and CBT

how do you detect and diagnose simple phobia?

Answer 20

• Assess the number of fears, impairment andcomorbidity to judge severity
• Ask about anxiety symptoms when patients presentwith specific fears or phobias

Answer 22

• Ask about a history of trauma when patients present with psychological
symptoms
• Become familiar with the diagnostic criteria for posttraumatic stress disorder

Question 23

How should you try and prevent post-traumatic symptoms?

Answer 23

• After major trauma, and providing there are no contraindications, consider
preventive treatment of posttraumatic symptoms with propranolol.
• Routine debriefing is not indicated
• Trauma-focused CBT can prevent the emergence of chronic PTSD in individuals
with post-traumatic symptoms lasting one month or longer after a traumatic
event

Question 34

what special considerations are there for children and adolescents?

Answer 34

• Reserve pharmacological treatments for children and adolescents who have not responded to psychological treatments, and in whom the potential benefits are likely to outweigh potential risks • If drug treatment is considered choose from the same range of treatments as with adults: SSRIs are a first-line choice from limited evidence, but avoid benzodiazepines and tricyclic antidepressants because of potential adverse effects • Consider dosages carefully in relation to age and size, starting with low doses • Carefully monitoring for potential adverse effects, being aware that children and adolescents may find it difficult to describe them

Question 35

Answer 35

• Treat as for patients younger than 65 years being mindful of the possibility of drug interactions, physical comorbidity, the need for lower doses due to reduced metabolism, or increased sensitivity to adverse effects
