Severe headache, stiff neck, and nausea are key symptoms of a hypertensive crisis, which is a life-threatening side effect of MAOIs when mixed with tyramine-rich foods or certain medications. The client must be referred to emergency medical care immediately.

Tremors, diarrhea, vomiting, and slurred speech are diagnostic indicators of Lithium toxicity, which can be fatal. The client must be referred to a physician or emergency department immediately.

Benzodiazepines (e.g., Xanax, Ativan) are highly addictive and can cause severe withdrawal symptoms, including seizures and death, if stopped abruptly. Cessation must be medically managed.

Atypical antipsychotics carry an FDA black-box warning indicating they are associated with an increased risk of death (due to stroke, heart failure, or pneumonia) when used in elderly patients with dementia-related psychosis.

Tardive Dyskinesia is a late-onset, often irreversible extrapyramidal side effect of long-term first-generation antipsychotic use, characterized by repetitive, involuntary movements of the face, mouth, and extremities.

Serotonin Syndrome is a life-threatening drug reaction caused by excessive serotonin levels, often when SSRIs are combined with other serotonergic agents (like St. John’s Wort). It is a medical emergency.

Stimulants are the first-line pharmacotherapy for ADHD, acting to increase dopamine and norepinephrine levels in the prefrontal cortex.

Clozapine carries a severe risk of agranulocytosis (a sudden drop in white blood cell count, making the client highly vulnerable to infection). Regular blood monitoring (ANC) is mandatory.

Akathisia is an extrapyramidal side effect of antipsychotics characterized by subjective feelings of inner restlessness and objective motor hyperactivity.

Buspirone (Buspar) is a non-benzodiazepine anxiolytic indicated for Generalized Anxiety Disorder. It is non-addictive and does not cause physical dependence or sedation.

ECT and TMS are evidence-based, medically managed somatic treatments for severe, treatment-resistant Major Depressive Disorder.

First-generation (typical) antipsychotics have high affinity for D2 receptors, carrying high risk of EPS. Atypical antipsychotics have lower D2 affinity and higher 5-HT2A affinity, carrying lower EPS risk but higher metabolic risk (weight gain, diabetes).

Anticholinergic side effects (dry mouth, constipation, mild sedation) are common when starting antidepressants (especially TCAs or SSRIs) and often resolve. Clients should be educated and referred to their prescribing physician for concerns.

MAOIs inhibit the breakdown of tyramine. Consuming foods high in tyramine while taking MAOIs causes rapid release of norepinephrine, leading to a dangerous hypertensive crisis.

Valproic Acid carries risks of hepatotoxicity and thrombocytopenia. Regular monitoring of liver enzymes and complete blood counts is required.
