What drugs interact with SSRIs and what are they at an increased risk of causing? (5) Think side effects
- Triptans for migrains- they increase serotonin sydrome
- NSAIDs: NICE guidelines advise ‘do not normally offer SSRIs’, but if given co-prescribe a proton pump inhibitor. GI bleed?
- warfarin / heparin: NICE guidelines recommend avoiding SSRIs and considering mirtazapine. GI bleed risk?
- aspirin- antiplatlet and SSRIs interect with platelet aggregation
- monoamine oxidase inhibitors (MAOIs) eg. Phenelzine, Selegiline they increase risk of serotonin syndrome

2 egs from this class
2 other egs and why you would give it in this particular case.
Benzos
chlordiazipoxide regimen or diazepam
Use lorazepam or oxezepam if known alcoholic liver disease (deranged LFTs)
Acute stress reaction manangemt
- First line
- What can be used in acute symptoms?
- First line = trauma-focused cognitive-behavioural therapy (CBT)

What can long term lithium use result in? and how does it happen?
How would it present? (4)
Investigations for diag? (2)
Hyperparathyroidism and resultant hypercalcaemia.
Remember the mnemonic: ‘stones, bones, abdominal moans, and psychic groans’.
This is postulated to occur by altering the homeostatic regulation of calcium, leading to parathyroid hyperplasia.
- U&Es
- parathyroid hormone levels (PTH)
are useful investigations to establish the diagnosis.

Try another SSRI
Switch to SNRI
MOA of Disulfiram aka antabuse
How often is it taken and how long does it last?
Why would it NOT be recommnded? (4 conditions)
- Irreversible inhibitor of acetaldehyde dehydrogenase
therefore casues a build up acetaldehyde - Results in unpleasant symptoms, including facial flushing and nausea and vomiting
It is taken once daily and its effects last seven days, working as a deterrent to prevent alcohol relapse
Not recommended for patients with underlying frailty, neurological, cardiac or hepatic conditions -Due to the reaction potentially being life-threatening
MOA/ How does it make the patient feel of Acamprosate aka Campral
