Pharmacists' Attitudes Towards Long-Term Use of Nasal Decongestants: A Cross-Sectional Study

Background

Rhinitis medicamentosa is a nonallergic inflammation of the nasal mucosa caused by topical decongestants overuse. It mainly affects young and middle-aged adults. Therefore, the aim of this study was to investigate the attitudes of pharmacists regarding the utilization of over-the-counter intranasal decongestants.

Methods

An online cross-sectional study was conducted from November 2021 to January 2022. The target population of the study included pharmacists who work in community pharmacies in Saudi Arabia. Binary logistic regression analysis was used to identify predictors of having positive attitude towards controlling the use of decongestant.

Results

A total of 220 participants were included in this study. Around 15.0% of them reported that ND come with a physician prescription. The majority of the participants (87.3%) reported that the less than 5 days is the maximum safe duration for the use of NDs. Overall, the study participants demonstrated moderately positive attitude towards controlling the use of decongestant with a mean attitude score of 2.5 (standard deviation: 1.2) out of 5; which represents 50.0% of the maximum score. Binary logistic regression analysis identified that pharmacists aged 31-40 years were two-folds more likely to have positive attitude towards controlling the use of decongestant compared to others (p<0.05). Around 45.9% of them reported that they recommend other over-the-counter treatments like nasal irrigation, nasal steroids, or antihistamine if they see a patient with RM asking for ND with or without prescription.

Conclusion

The majority of pharmacists in Saudi Arabia demonstrated sufficient awareness and understanding on the adverse effects associated with the excessive use of NDs. Rhinitis medicamentosa can be avoided by appropriate measures, highlighting the importance of raising awareness about the excessive use of decongestants among healthcare professionals and patients alike.

[Rhinitis medicamentosa]

One type of non-allergic non-infectious rhinitis is represented by a heterogeneous group of rhinitis medicamentosa, which can be divided into several pathogenetic types. The most common rebound nasal congestion associated with the use of topical decongestants. Excessive use of intranasal decongestants leads to a decrease in the number of alpha-adrenoreceptors on the surface of cell membranes and uncoupling their connection with the G-protein and the development of tachyphylaxis. To prevent the development of rebound nasal congestion caused by topical decongestants, it is important to limit the frequency of their use. In most cases, the duration of the use of vasoconstrictor drugs should be limited to 5-7 days, according to Patient information leaflets for the drugs. However, in patients who have had a history of episodes of rebound nasal congestion, which develops including the previously indicated periods, the duration of decongestant therapy should be limited to 3 days. Rhinitis associated with local inflammation is caused by the intake of acetylsalicylic acid (ASA) or other non-steroidal anti-inflammatory drugs. Currently, the so-called "aspirin triad" is well known - a combination of bronchial asthma, rhinosinusitis (often polyposis) and intolerance to ASA. Neurogenic rhinitis develops due to the use of drugs that violate vascular tone, for example, antihypertensive drugs or type 5 phosphodiesterase inhibitors. Drug-induced rhinitis has a significant impact on the patient's quality of life: nasal congestion, rhinorrhea, secondary night apnea, insomnia as a result of nasal breathing disturbances, headaches, irritability, weakness after sleepless nights disturb patients to a large extent. Timely diagnosis and withdrawal of a provocative drug, the use of topical corticosteroids in case of severe rhinitis are the basis of the treatment of rhinitis medicamentosa. In severe cases, there is a need, including surgical treatment, such as, for example, submucosal laser destruction of the lower nasal concha.

Management of Rhinitis Medicamentosa: A Systematic Review

OBJECTIVE

Rhinitis medicamentosa (RM) is a common condition resulting from overuse of topical nasal decongestants. Despite the prevalence in otolaryngologic practice, a clear treatment protocol has not been established. Our objective was to review the current published literature pertaining to the treatment of RM with the possibility of finding data that support one treatment over another.

DATA SOURCES

PubMed, Embase, Cochrane, and Web of Science databases were examined for patients diagnosed with RM resulting from chronic use of topical nasal decongestants.

REVIEW METHODS

The PRISMA standard (Preferred Reporting Items for Systematic Reviews and Meta-analyses) was utilized to identify English-language studies reporting treatment of patients with the primary diagnosis of RM after chronic use of a topical decongestant. Outcome measures of interest included patient-reported symptom relief and objective parameters. MINORS criteria (methodological index for nonrandomized studies) were used to assess the quality of articles.

RESULTS

A total of 350 articles were identified, 9 of which met final inclusion criteria for qualitative analysis. Outcomes defined in each publication were highly varied and relied on several unstandardized measures. The most commonly reported treatment option was topical nasal steroids, although overall there was limited evidence on which to base treatment recommendation.

CONCLUSIONS

There is not adequate evidence to develop a standardized treatment protocol for RM. The development of a uniform questionnaire, standard outcomes to be measured, and a method of assessing such outcomes is necessary. Prospective randomized controlled studies are warranted to determine the optimal treatment regimen following diagnosis of RM.

Rhinologic issues in pregnancy

The diagnosis and treatment of rhinitis, sinusitis, and epistaxis during pregnancy present unique challenges to the otolaryngologist. Poorly controlled sinonasal disease may have significant adverse effects on the mother's quality of life and pregnancy outcomes and the lack of adequately controlled safety data limits the clinician's ability to make informed decisions about management. At the conclusion of this discussion, the reader should be familiar with the available literature and evidence-based guidelines regarding the safety and indications for radiographic imaging, clinical testing, medical intervention, and surgical treatment of sinonasal disease in pregnant patients. A review was performed of pertinent guidelines regarding the management of gestational rhinitis, sinusitis, and epistaxis, including the diagnostic and therapeutic limitations and physiological changes specific to pregnancy. A study population of four patients was analyzed to highlight the steps of management by reviewing the patient charts including pertinent history, physical examination, clinical course, and operative reports. Two patients with epistaxis and two patients with rhinosinusitis ranging from 27 to 38 years of age and between 16 and 35 weeks gestation were analyzed. The treatment of sinonasal disease during pregnancy is challenging and a thorough knowledge of the available medical evidence and treatment guidelines is necessary to optimize pregnancy outcomes. When the severity of disease precludes the possibility of delaying treatment, the clinician should provide a limited intervention that optimizes the mother's health without placing the fetus at significant risk.
