Dosage & Administration

Standard regimens per Canadian guidelines

When considering the use of ddavp, it's important to follow the recommended dosages outlined by Canadian health guidelines. Here's how the dosages typically break down:

Diabetes Insipidus: For adults, the starting dose is usually 0.1 to 0.2 mg taken orally once daily, which can be adjusted according to patient response.

Bedwetting in Children: Initial doses may range from 0.2 to 0.6 mg before bedtime, again titrated based on effectiveness and tolerance.

Secondary Hyperparathyroidism: Starting doses might be around 0.1 to 0.4 mg to be administered twice daily.

It's recommended to reassess these dosages regularly to ensure optimal therapeutic outcomes.

Adjustments by patient type (with Canadian clinical notes)

Select patient populations may require dosage adjustments. For instance:

• Elderly: Patients over 65 years should be monitored closely due to possible renal function decline; typically, lower doses are advisable.
• Renal Impairment: Caution is critical. If a patient's creatinine clearance falls below 50 mL/min, dosing must be adjusted, potentially starting at the low end of the dosage spectrum.
• Pediatric Considerations: Dosing for children under 12 should be carefully initiated, adjusting based on specific responses and side effects.

Making these adjustments ensures a safer and more effective treatment plan tailored to individual needs.
