In some cases, it’s not a matter of whether you should choose nasal or oral corticosteroids. You may need to decide whether corticosteroids are a good option for you overall. Some people don’t respond well to any form of steroids, making these types of medications useless for allergy symptoms. Your doctor might order a blood test to see whether or not this is the case for you. Discuss any past reactions to steroid medications with your doctor. Tell them about any family history of issues from taking this medication. This can help avoid the potential for dangerous side effects.
