Psychiatry Flashcards
what diseases is cotard syndrome associated with? (2)
severe depression and psychotic disorders
SSRI of choice post myocardial infarction
sertraline
SSRI interactions
NSAIDs: NICE guidelines advise ‘do not normally offer SSRIs’, but if given co-prescribe a proton pump inhibitor
warfarin / heparin: NICE guidelines recommend avoiding SSRIs and considering mirtazapine
aspirin
triptans - increased risk of serotonin syndrome
monoamine oxidase inhibitors (MAOIs) - increased risk of serotonin syndrome
SSRI: when to review post starting?
Following the initiation of antidepressant therapy patients should normally be reviewed by a doctor after 2 weeks. For patients under the age of 25 years or at increased risk of suicide should be reviewed after 1 week. If a patient makes a good response to antidepressant therapy they should continue on treatment for at least 6 months after remission as this reduces the risk of relapse.
SSRI in pregnancy
- Use during the first trimester gives a small increased risk of congenital heart defects
- Use during the third trimester can result in persistent pulmonary hypertension of the newborn
- Paroxetine has an increased risk of congenital malformations, particularly in the first trimester
Discontinuation symptoms SSRI
Gastrointestinal symptoms common. also:
- increased mood change
- restlessness
- difficulty sleeping
- unsteadiness
- sweating
- gastrointestinal symptoms: pain, cramping, diarrhoea, - vomiting
- paraesthesia
which ATYPICAL antipsychotic has a generally good side-effect profile, particularly for prolactin elevation
aripiprazole
Adverse effects of atypical antipsychotics
weight gain
hyperprolactinaemia
(stroke/ VTE risk)
Seasonal affective disorder management
you would begin with psychological therapies and follow up with the patient in 2 weeks to ensure that there has been no deterioration. Following this an SSRI can be given if needed.
clozapine side effects
agranulocytosis (1%), neutropaenia (3%)
reduced seizure threshold - can induce seizures in up to 3% of patients
constipation
myocarditis: a baseline ECG should be taken before starting treatment
hypersalivation
dose adjustment of cloazpine is needed if…
start or stop smoking
ECT side effects
Short-term side-effects
headache
nausea
short term memory impairment
memory loss of events prior to ECT
cardiac arrhythmia
Long-term side-effects
some patients report impaired memory
mirtazapine mechanism of action
alpha2-adrenergic receptorspeak incidence of seizures
peak incidence of seizures alcoholics
36hr
peak incidence delirium tremens
48-72 hours: coarse tremor, confusion, delusions, auditory and visual hallucinations, fever, tachycardia
when to admit people with ETOH
patients with a history of complex withdrawals from alcohol (i.e. delirium tremens, seizures, blackouts) should be admitted to hospital for monitoring until withdrawals stabilised
when to NOT give chlordiazepoxide for withdrawal of ETOH
liver cirrhosis –> Lorazepam
