Techniques of intranasal steroid use.

OBJECTIVE

The effectiveness of topical intranasal steroids (INS) sprays for the treatment of allergic and nonallergic rhinitis may be limited by lack of instruction in the optimal spray technique. To determine whether the technique used affects the efficacy and safety of the product, this review of evidence had the goal of identifying and establishing a preferred method of applying INS sprays.

STUDY DESIGN

A MEDLINE search of pertinent literature on 7 INS and 1 intranasal antihistamine spray preparations conducted with the use of appropriate search terms, yielded an initial 121 articles, 29 of which were identified as appropriate for review and grading for quality of evidence.

RESULTS

The analysis provided no definitive evidence regarding how best to instruct patients to use INS or antihistamine spray devices.

CONCLUSIONS

On the basis of a lack of clear evidence regarding instructions to maximize efficacy and safety of these drugs, the panel recommended a 7-step standard technique.
