Can any of the patient's medications, including atorvastatin, citalopram, empagliflozin, ferrous sulfate, gabapentin, insulin glargine, losartan, metFORMIN, mirtazapine, QUEtiapine, semaglutide, dicyclomine, and albuterol, cause hot flashes in an adult patient with type 2 diabetes, hypertension, and a history of mental health issues?

Medications That Can Cause Hot Flashes

Yes, several of your medications can cause hot flashes: citalopram (SSRI), mirtazapine (antidepressant), and quetiapine (antipsychotic) are the primary culprits, with gabapentin potentially contributing in some patients.

Primary Offenders

SSRIs (Citalopram 10 mg)

• Citalopram is paradoxically both a cause and treatment of hot flashes 1, 2
• SSRIs like citalopram can disrupt thermoregulation through serotonergic mechanisms, though they reduce hot flashes by 50-65% when used therapeutically at higher doses 1
• At your lower dose (10 mg for depression/anxiety), the thermoregulatory disruption may outweigh any therapeutic benefit for hot flashes 3

Antipsychotics (Quetiapine 100 mg)

• Quetiapine significantly impairs thermoregulation and increases hot flash risk 4
• Second-generation antipsychotics like quetiapine cause moderate to large increases in excessive sweating and heat-related symptoms through multiple mechanisms 3, 5
• Quetiapine is specifically listed among antipsychotics with more metabolic effects and thermoregulatory disruption 4
• The American Diabetes Association guidelines note that quetiapine requires metabolic monitoring due to these effects 4

Antidepressants (Mirtazapine 15 mg)

• Mirtazapine is associated with weight gain and can contribute to hot flashes 4
• While mirtazapine can actually reduce SSRI-induced sweating when used as an adjunct, it can cause thermoregulatory symptoms on its own 3
• The weight gain associated with mirtazapine (closely linked to hot flashes) is well-documented 4

Secondary Contributors

Gabapentin 300 mg

• Gabapentin is typically used to treat hot flashes (effective at 900 mg/day), reducing them by 46% 1, 2
• However, at your lower dose (300 mg), it's unlikely to provide therapeutic benefit for hot flashes 1
• Gabapentin itself rarely causes hot flashes but can cause flushing in some patients 1

Medications That Do NOT Cause Hot Flashes

The following medications in your regimen are not associated with hot flashes:

• Atorvastatin: Statins do not cause hot flashes 4
• Empagliflozin, Metformin, Semaglutide: Diabetes medications are not linked to hot flashes 4
• Insulin glargine: Does not affect thermoregulation 4
• Losartan: Angiotensin II receptor blockers are weight-neutral and do not cause hot flashes 4
• Ferrous sulfate: Iron supplementation does not cause hot flashes
• Dicyclomine: Anticholinergics can impair thermoregulation in extreme heat but don't typically cause hot flashes 6
• Albuterol: Beta-agonists don't cause hot flashes 6

Clinical Algorithm for Management

Step 1: Identify the Most Likely Culprit

• If hot flashes are severe and bothersome, quetiapine is the most likely cause given its potent effects on thermoregulation 4, 5
• If accompanied by excessive sweating, consider citalopram or mirtazapine as contributors 3

Step 2: Consider Medication Adjustments

• For quetiapine: Discuss with prescriber about switching to aripiprazole or ziprasidone, which have fewer metabolic and thermoregulatory effects 4
• For citalopram: The dose is already low; increasing it paradoxically might help (SSRIs reduce hot flashes at therapeutic doses of 10-20 mg for citalopram) 1, 2
• For mirtazapine: Consider switching to bupropion if clinically appropriate, as it has minimal thermoregulatory effects 4, 3

Step 3: Add Targeted Treatment if Medication Changes Aren't Feasible

• Gabapentin dose optimization: Increase from 300 mg to 900 mg/day (if tolerated), which reduces hot flashes by 46% with no drug interactions 1, 2
• Avoid adding paroxetine or fluoxetine as they have significant drug interactions 1, 2
• Consider clonidine 0.1 mg daily, which reduces hot flashes by up to 46% through alpha-2 adrenergic mechanisms 1, 7

Step 4: Non-Pharmacologic Interventions

• Weight loss of ≥10% can eliminate hot flash symptoms 2
• Cognitive behavioral therapy reduces perceived burden of hot flashes 2
• Avoid triggers: Caffeine, alcohol, spicy foods, and hot environments 7

Critical Pitfalls to Avoid

• Don't abruptly discontinue citalopram or mirtazapine, as withdrawal itself causes sweating and hot flashes 3
• Don't assume all symptoms are medication-related: Rule out hyperthyroidism, carcinoid syndrome, and pheochromocytoma if hot flashes are severe or accompanied by other symptoms 7
• Monitor for heat-related illness: Your combination of medications (diuretics through potential fluid shifts, antipsychotics, anticholinergics) increases risk during hot weather 8, 6
• Don't overlook the psychiatric indication: Quetiapine and citalopram are treating important conditions; any changes must balance mental health stability against hot flash burden 4
