Sodium and Azelastine Hydrochloride, Fluticasone Propionate

Here is the interaction we found between these two, with the evidence behind it.

Moderate

CORTICOSTEROIDS

Why this applies to Azelastine Hydrochloride, Fluticasone Propionate

Azelastine Hydrochloride, Fluticasone Propionate falls under CORTICOSTEROIDS — the group Sodium interacts with.

Concomitant use of mineralocorticoids and some glucocorticoids with sodium supplements might increase the risk of hypernatremia.
Mineralocorticoids and some glucocorticoids (corticosteroids) cause sodium retention. This effect is dose-related and depends on mineralocorticoid potency. It is most common with hydrocortisone, cortisone, and fludrocortisone, followed by prednisone and prednisolone.
Severity Moderate Likelihood Possible Evidence D

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the good news: Dymista is a nasal spray that combines azelastine (an antihistamine) with fluticasone (a steroid). The steroid concern on file is about corticosteroids that make your body hold onto sodium, which in theory could nudge sodium levels higher if you're also taking sodium supplements. But fluticasone in a nasal spray is used in tiny amounts that act mostly right in your nose, with very little reaching the rest of your body.

So for most people using Dymista as directed, adding everyday dietary sodium is very unlikely to cause a real problem. This is a theoretical, pharmacology-based caution, not something seen often in practice. Still, if you have high blood pressure, heart, or kidney issues, or you're considering deliberate sodium supplements, check with your doctor or pharmacist first.

From our pharmacist’s overview on the Azelastine Hydrochloride, Fluticasone Propionate page

“Grapefruit is my first concern for anyone using Dymista (azelastine with fluticasone), the combination allergy nasal spray. The fluticasone in it is cleared by a liver enzyme called CYP3A4, and grapefruit blocks that enzyme well enough that steroid levels can climb.”

About Sodium

What is Sodium?

  • Replacing fluids and electrolytes
  • Preventing dehydration during exercise or illness
  • Treating low blood sodium (under medical care)
  • Seasoning and food preservation
  • Antacid (as sodium bicarbonate)

Sodium is an essential mineral and electrolyte your body needs to balance fluids, support nerves, and help muscles work. Most people in modern diets get more than enough—often too much—from food, so supplements are rarely needed except for specific medical reasons like dehydration or low blood sodium. Talk to your doctor or pharmacist before deliberately adding sodium, especially if you have high blood pressure, heart, or kidney problems.
