NAPLEX (North American Pharmacist Licensure Examination) Practice Exam

Intranasal cromolyn is commonly used for the treatment of allergic rhinitis. When considering the minimum age for safe use of intranasal cromolyn, it is important to take into account the child's ability to use the drug properly and its safety profile for that age group. Typically, children as young as 2 years old are able to effectively use intranasal cromolyn with proper supervision and guidance from healthcare professionals. This age is considered safe due to the child's increasing ability to follow instructions and administer the medication correctly. Therefore, the correct answer is B (2 years).

Option A (5 years), Option C (12 years), and Option D (6 months) are incorrect because they do not align with the generally accepted age recommendation for safe use of intranasal cromolyn, which is 2 years.
