Does Nasacort increase blood pressure? 

Does Nasacort increase blood pressure? 

No, Nasacort does not increase blood pressure usually. In fact, it is considered safe to be used by hypertensive patients and does not interact with any antihypertensive medication (1). 

However, Nasacort has a corticosteroid in it, which most likely will not affect your blood pressure but it can affect the amount of water and electrolytes in your body. This can lead to water retention which may increase your blood pressure. 

However,  it’s a long shot with Nasacort as it’s a nasal spray and the amount of corticosteroids entering your body through a single dose administration is not significant enough to cause water retention or high blood pressure. 

If you are concerned about high BP, talk to your healthcare provider. Other factors could be responsible for your high blood pressure, and proper evaluation is necessary to address the problem.
