Dosage & Administration

Standard regimens per Canadian guidelines

When it comes to initiating treatment with the combination of bupropion and naltrexone (Contrave), standard dosing is paramount for efficacy and safety. According to Canadian clinical guidelines, adults typically follow a gradual titration schedule:

• Week 1: 1 tablet in the morning (8 mg naltrexone / 90 mg bupropion).
• Week 2: 1 tablet in the morning and 1 tablet in the evening (total of 16 mg naltrexone / 180 mg bupropion).
• Week 3: 2 tablets in the morning and 1 tablet in the evening (total of 16 mg naltrexone / 180 mg during the day and 8 mg at night).
• Week 4 and beyond: 2 tablets twice daily (32 mg naltrexone / 360 mg bupropion).

This regimen is designed to minimize side effects while monitoring patient tolerance and weight loss progress. If there’s insufficient weight loss (<5% of body weight) after 12 weeks, the treatment should be reassessed.

Adjustments by patient type (with Canadian clinical notes)

Individualization of dosage is crucial, especially for vulnerable populations. For elderly patients, it is advisable to begin with a lower dose due to potential increased sensitivity. No strict adjustments are mandated unless significant comorbid conditions exist.

For those with renal impairments, Canadian guidelines suggest:

• Mild impairment: No dosage alteration.
• Moderate to severe impairment: Avoid the medication due to heightened risk of adverse reactions.

In cases of hepatic impairment, those with moderate to severe conditions should avoid this medication altogether. For mild impairment, initiating at a lower dosage is wise.
