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.
Studies on corticosteroids tend to lean toward the extreme use, rather than the average use. For example, some studies look at corticosteroids for extreme and rarer cases of eczema. This makes it harder to research what long-term studies are out there on steroid use. To complicate things further, corticosteroids can be oral, topical, injected, or inhaled, and this dramatically changes the benefits and risks, and in turn the short-term and long-term effects. Speak with your doctor and pharmacist on what, if any, long-term studies out there are relevant to your own medical treatment.
