Summary
Tricyclics block norepinephrine reuptake and may enhance the vasopressor response to sympathomimetic vasoconstrictors. With intranasal oxymetazoline, systemic absorption is usually small, but hypertension and arrhythmia are possible, especially with excessive dosing.
What this interaction means in plain words
Imipramine and Oxymetazoline intranasal have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.
Why it happens
Pharmacodynamic synergism: TCA inhibition of norepinephrine reuptake potentiates alpha-adrenergic agonist effects.
What to do
Use oxymetazoline at the labeled dose and for short duration only, and monitor blood pressure and heart rate if symptoms occur. Avoid combined use with vasoconstrictor-containing dental anesthetics where practical.
