Medication Safety Reference

All antidepressants carry a black box warning for increased risk of suicidal thinking and behavior in children, adolescents, and young adults up to age 25, especially in the first weeks of treatment or after a dose change.

Close monitoring during this early period is essential, and any new or worsening suicidal thoughts should be reported to a provider right away.

Clozapine (Clozaril) can cause agranulocytosis, a severe drop in infection-fighting white blood cells, which is why mandatory absolute neutrophil count (ANC) monitoring is required throughout treatment.

Lamotrigine (Lamictal) carries a black box warning for Stevens-Johnson Syndrome (SJS), a rare but life-threatening skin reaction. Slow, gradual titration significantly reduces this risk.

Valproate (Depakote) carries black box warnings for liver toxicity, pancreatitis, and birth defects (neural tube defects) when taken during pregnancy. Baseline and periodic liver function tests are recommended.

Carbamazepine (Tegretol) carries black box warnings for agranulocytosis, aplastic anemia, and Stevens-Johnson Syndrome — the SJS risk is notably higher in patients of Asian descent carrying the HLA-B*1502 gene variant, which can be screened for before starting.

Bupropion (Wellbutrin) lowers the seizure threshold, so it is generally avoided in people with a seizure history, eating disorders, or heavy alcohol use, and doses should never exceed prescribed limits.

MAOIs (like phenelzine or tranylcypromine) combined with other serotonergic medications (SSRIs, SNRIs, tramadol, triptans) can trigger life-threatening serotonin syndrome, and combining with tyramine-rich foods can trigger a hypertensive crisis.

A washout period of at least 2 weeks (5–6 weeks after fluoxetine) is required when switching to or from an MAOI.

NSAIDs, thiazide diuretics, ACE inhibitors, low-sodium diets, and dehydration can all raise lithium levels toward toxicity, so these combinations require careful monitoring.

Depakote inhibits the breakdown of Lamictal, roughly doubling its blood level — this combination requires a slower titration and often a lower Lamictal dose to reduce SJS risk.

Cigarette smoke induces the liver enzyme CYP1A2, which breaks down clozapine faster. Starting smoking may require a higher dose; quitting smoking may require a lower dose — this should always be managed with your prescriber.

Lithium requires regular blood level checks (therapeutic range approximately 0.6–1.2 mEq/L) plus periodic kidney function, thyroid (TSH), and sometimes ECG monitoring.

ANC (absolute neutrophil count) is checked weekly for the first 6 months, every 2 weeks for the next 6 months, then monthly thereafter if levels remain normal — this schedule is mandatory and cannot be skipped.

Carbamazepine requires periodic complete blood counts and liver function tests to monitor for the rare but serious risks of blood dyscrasias and liver toxicity.

Benzodiazepine and alcohol withdrawal are the two withdrawal syndromes that can be fatal, with risks including seizures and delirium tremens. A supervised, gradual taper — never abrupt discontinuation — is essential.

Opioid withdrawal is intensely uncomfortable — symptoms include muscle aches, nausea, sweating, tearing, and anxiety — but is rarely life-threatening on its own. Medication-assisted treatment (like buprenorphine/Suboxone) can significantly ease this process.
