Summary
Oxymetazoline is an alpha agonist, and with nonselective beta-blockade its vasoconstriction may be unopposed, so a rise in blood pressure is possible. Systemic absorption from nasal use is usually low, so clinically significant effects are uncommon at standard doses.
What this interaction means in plain words
Nadolol 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
Unopposed alpha-1 vasoconstriction due to beta-2 blockade by nadolol.
What to do
Use nasal oxymetazoline at labeled doses and for short periods only. Monitor blood pressure in patients with hypertension, and avoid with intranasal dental anesthetic combinations in these patients.
What to ask your pharmacist
- Is there anything I should notice while taking both?
- Do I need to tell my doctor at the next visit?
