Cognitive symptoms (headache, agitation), autonomic symptoms (sweating, tachycardia), somatic symptoms (muscle twitching, hyper-reflexia).
New cards
14
How do tricyclic antidepressants (TCAs) work?
They block the reuptake of norepinephrine and serotonin.
New cards
15
What are some side effects of tricyclic antidepressants (TCAs)?
Sedation, anticholinergic effects, may increase suicide risk early in treatment.
New cards
16
What should be avoided when taking monoamine oxidase inhibitors (MAOIs)?
High tyramine foods (e.g., aged cheese, red wine) and certain medications.

New cards
18
What might be a notable effect of bupropion?

New cards
19
What is the narrow therapeutic range for lithium?
0.5-1.5 mEq/L.
New cards
20
What is a potential consequence of lithium toxicity?
Diarrhea, dizziness, nausea/vomiting, excessive urine output, muscle twitching, potentially leading to coma.
New cards
21
What crucial role do electrolytes play in patients taking lithium?
Lithium can cause sodium loss, which can lead to dehydration and hyponatremia.
New cards
22
What is the recommended action for patients experiencing adverse symptoms from antidepressants?
Don’t stop the medication suddenly; consult a healthcare provider.
New cards
23
What are the potential risks of antiepileptic drugs used in bipolar disorder treatment?
Teratogenic effects, blood dyscrasias, and potential for agranulocytosis.
New cards
24
What dietary considerations should be taken for patients on MAOIs?
Avoid high tyramine foods to prevent hypertension crises.
New cards
25
What are some behavioral signs that could indicate a risk of suicide?
Increased energy coupled with sadness, saying goodbyes, and giving away possessions.
New cards
26
What type of interactions does St. John's Wort have with prescriptions?
Can decrease effectiveness or increase toxicity of certain medications.
New cards
27
What is the function of mood stabilizers like Lithium?
To even out mood fluctuations and stabilize manic or depressive phases.
New cards
28
What should be assessed when monitoring the effectiveness of depression treatment?

It's a serotonin norepinephrine reuptake inhibitor (SNRI) effective for depression and pain.
New cards
32
Why is it critical to ensure a period of time between using MAOIs and SSRIs?
To avoid serotonin syndrome, as both can increase serotonin levels.
New cards
33
What needs to be monitored for patients on Valproic acid?
Watch for blood counts due to thrombocytopenia and evaluate for hepatic toxicity.
New cards
