What is the dosing schedule for Infliximab after the initial doses at Weeks 0, 2, and 6?

Every 4 weeks
Every 6 weeks
Every 8 weeks
Every 12 weeks

The correct answer is: Every 8 weeks

After the initial doses at Weeks 0, 2, and 6, the usual recommended maintenance dose for Infliximab is every 8 weeks. This is because the half-life of the medication is approximately 8 weeks. It is important to follow the recommended dosing schedule to ensure maximum efficacy and to prevent potential flare-ups of the condition being treated. Options A, B, and D are incorrect because they do not align with the half-life of the medication and may result in suboptimal treatment outcomes. Additionally, missing doses or delaying the dosing schedule may also lead to reduced effectiveness and potential treatment failure. It is essential to consult with a healthcare provider to determine the appropriate dosing schedule for Infliximab based on individual needs and medical history.
