Dosage & Administration

When it comes to managing erectile dysfunction, the right dosage of Viagra can make all the difference. Standard dosing recommendations from Canadian guidelines suggest the following:

• Initial Dose: 50 mg taken orally approximately 30-60 minutes before sexual activity.
• Adjustment Range: Doses can range from 25 mg to 100 mg, with a maximum of one dose per day.

Factors that may influence dosage adjustments include:

• Age: Seniors over 65 years may require a lower starting dose, typically 25 mg.
• Health Conditions: Those with renal or hepatic impairments should also start at the lower dose, adjusting gradually based on response and tolerance.

The aim is to personalize treatment while minimizing the risk of side effects. This approach allows healthcare providers to ensure that safety and efficacy align with patient needs.

Adjustments by patient type

For specific populations, especially seniors and patients with comorbidities, caution is paramount when prescribing Viagra. Health Canada highlights:

• Seniors may be more sensitive to side effects, thus beginning treatment with a reduced dosage of 25 mg is advisable.
• Those with cardiovascular diseases require careful monitoring when using Viagra alongside other medications.
• Patients with a history of retinal disorders should be informed about potential risks, as there’s a possibility of visual disturbances.
