Major Side Effects Flashcards
HAM side effects
antiHistamine: sedation, weight gain
antiAdrenergic: hypotension
antiMuscarinic: dry mouth, blurred vision, urinary retention
HAM side effects are seen with…
TCAs and low-potency antipsychotics (chlorpromazine, thorazine)
Serotonin syndrome
confusion, flushing, diaphoresis, tremor, myoclonic jerks, hyperthermia, hypertonicity, rhabdomyolysis, renal failure, death
Serotonin syndrome is seen with…
SSRIs, MAOIs (especially the combination of)
- drugs that inc serotonin may also be in OTC cough remedies
Hypertensive crisis is seen with…
MAOIs plus foods with tyramine (red wine, cheese, chicken liver, cured meats) or plus sympathomimetics
- causes a buildup of stored catecholamines

Extrapyramidal side effects are seen with…
high-potency typical antipsychotics (haloperidol, fluphenazine)
- occur within days of starting, reversible, but can be life-threatening
What drugs are used to treat extrapyramidal symptoms produced by neuroleptics?
benzotropine (Cogentin, an anticholinergic), diphenhydramine (Benadryl), trihexyphenidyl (Artane)
occasionally pramipexole (dopamine agonist)
Hyperprolactinemia is seen with…
high potency traditional antipsychotics and risperidone
Tardive dyskinesia
choreoathetoid muscle movements (usually of mouth and tongue) ex. grimacing, tongue protrusion

after LONG-TERM antipsychotic use (especially high-potency typical antipsychotics)
- may be irreversible
Neuroleptic malignant syndrome
fever, tachycardia, hypertension, tremor, elevated creatine phosphokinase (CPK), “lead pipe” rigidity
- MEDICAL EMERGENCY (20% mortality)
Neuroleptic malignant syndrome is seen with…
all antipsychotics (inc risk with high-potency traditional antipsychotics)
