Cetirizine in adult preparations with dosage concentrations of 10 mg is categorized under which schedule?

Cetirizine at a 10 mg concentration in adult preparations is categorized as unscheduled because it is available over-the-counter without a prescription. This categorization aligns with the nature of cetirizine as a widely used antihistamine for allergy relief, which can be safely self-administered by adults. In Saskatchewan, unscheduled products are those that can be sold in a retail setting without the need for pharmacy oversight or professional supervision, enabling easier access for consumers.

In this context, it's important to recognize that Schedule 2, Schedule 3, and Schedule 4 products typically require varying degrees of professional oversight or prescription to ensure safe usage. For instance, Schedule 2 might require the intervention of a pharmacist, while Schedule 3 requires a professional to provide guidance but is still accessible without a prescription. Schedule 4 generally involves prescription medications that pose more significant safety or efficacy concerns, necessitating closer monitoring by healthcare providers. Thus, cetirizine's classification as unscheduled highlights its safety profile for general use in the specified dosage.
