⚠ Key cautions

Cautions: precursor to catecholamines (dopamine, norepinephrine, epinephrine) and thyroid hormone. Prescription interactions: CONTRAINDICATED with MAOIs (theoretical risk of hypertensive crisis from increased catecholamine synthesis); caution with thyroid hormone replacement (tyrosine is a thyroid-hormone precursor — monitor thyroid function); may compete with levodopa for intestinal/blood-brain-barrier transport — separate dosing. Priority: Moderate — clear MAOI contraindication.
