Dosage & Administration

When it comes to avanafil, understanding the right dosage and how to take it is crucial for effectiveness and safety.

Standard regimens per Canadian guidelines

In Canada, avanafil is primarily found under the brand name **Stendra**, available in three tablet dosages: **50 mg, 100 mg,** and **200 mg**. The recommended starting point for most adults is the **100 mg** dosage. Patients should take it approximately **15 minutes** prior to sexual activity, allowing sufficient time for the medication to work. A maximum of one tablet can be taken per day.

For elderly patients or those particularly sensitive to medication, starting with the **50 mg** dosage is advisable. This approach helps mitigate any potential side effects while still providing the desired benefits. If necessary, the dosage can be increased to **200 mg** for individuals who find the lower dose ineffective.

Adjustments by patient type (with Canadian clinical notes)

Dosage adjustments may be required for specific patient populations. For elderly individuals, it’s common practice to start at a **50 mg** dose due to the heightened risk of side effects.

Similarly, for patients with liver impairment, caution is necessary. They might require a lower starting dose or closer monitoring to avoid complications. In cases of severe liver impairment, avanafil is not recommended at all.

DIN number relevance

In Canada, the Drug Identification Number (DIN) plays a crucial role in the regulation and availability of prescription medications like avanafil. The DIN is a unique identifier assigned to each medication version sold in Canada, simplifying the purchasing and tracking process.
