Usage Basics for Canadians

Desmopressin’s International Nonproprietary Name (INN) is desmopressin acetate. In Canada, it’s marketed under various brand names, including DDAVP and Minirin. Health Canada dictates that desmopressin is classified as a prescription-only medication, meaning that patients cannot purchase it over-the-counter without a prescription. To legally and safely use desmopressin, a Drug Identification Number (DIN) must be issued to ensure proper regulation and quality standards are met.

INN, Brand Names Available in Canada

Commonly recognized brand names include DDAVP and Minirin, which are available in forms such as oral tablets and nasal sprays. Each form has its specific use cases and should be prescribed accordingly.

Legal Classification Under Health Canada

Only prescription versions of desmopressin can be accessed in Canada. It’s essential for patients to consult healthcare providers for proper evaluation, prescription, and ongoing monitoring to ensure safe use and adherence to treatment protocols.

Canadian Dosing Guide

Dosing of desmopressin can vary significantly based on the specific condition treated, such as diabetes insipidus or nocturnal enuresis. Health Canada provides guidelines emphasizing that individual patient factors play a crucial role in determining the appropriate dose. Standard starting doses generally range from 0.1 mg to 0.4 mg, but adjustments may be necessary based on the patient's response to treatment and tolerability.

Standard Regimens

Typical initial dosages for adults can be adjusted according to clinical outcomes. It’s important to communicate with healthcare providers throughout the treatment process for optimal adjustments.

Adjustments for Comorbidities

Patients with underlying health conditions, such as diabetes, should have their dosing plans tailored carefully. Healthcare providers need to assess these comorbidities consistently and make necessary dose adjustments under strict supervision.

Q&A — “What If I Miss a Dose Under My Provincial Drug Plan?”
