Summary
Tricyclics block norepinephrine reuptake and may enhance pressor responses to sympathomimetic vasoconstrictors. Systemic absorption from intranasal oxymetazoline is small, so a clinically important rise in blood pressure is uncommon with ordinary use but is possible with heavy use.
What this interaction means in plain words
Amitriptyline 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 synergy through increased synaptic norepinephrine and alpha-1 receptor stimulation.
What to do
Use oxymetazoline at the labeled dose for short courses only. Monitor blood pressure and heart rate if use is frequent or the patient has cardiovascular disease.
