Vedolizumab is a gut-selective monoclonal antibody used for moderate-to-severe ulcerative colitis and Crohn's disease.
Adult dose
Dose adjustments
Vedolizumab has not been studied in patients with renal or hepatic impairment; no dose recommendations can be made.
Dose auto-extracted from UK Summary of Product Characteristics (SPC) via the eMC; US FDA prescribing information (openFDA / DailyMed) — cross-check; US labelling may differ from UK — not yet clinician-verified. Always confirm against the product SmPC and your local formulary before prescribing.
Contraindications
- Hypersensitivity to the active substance or to any of the excipients
- Active severe infections such as tuberculosis, sepsis, cytomegalovirus, listeriosis
- Opportunistic infections such as progressive multifocal leukoencephalopathy (PML)
Side effects
- Nasopharyngitis (very common)
- Headache (very common)
- Arthralgia (very common)
- Nausea, pyrexia, fatigue and cough (common)
- Injection site reactions with subcutaneous administration — pain, oedema, erythema or pruritus, reported in 5.1% of patients (common)
- Anaphylactic reaction and anaphylactic shock (very rare)
Interactions
- Section 4.5 of the UK SPC was not captured in the fetched bundle — the following are from the US ENTYVIO prescribing information (section 7) and should be verified against the UK SPC
- Natalizumab products — avoid concomitant use because of the potential for increased risk of PML and other infections (US label)
- TNF blockers — avoid concomitant use because of the potential for increased risk of infections (US label)
- CYP450 substrates — vedolizumab may normalise CYP450 enzyme formation by modulating chronic inflammation; on starting or stopping vedolizumab, monitor drug concentrations or other therapeutic parameters and adjust the substrate dose as needed (US label)
Clinical monograph
How it works
It binds the alpha-4 beta-7 integrin on circulating lymphocytes, blocking their adhesion to MAdCAM-1 and reducing trafficking of inflammatory cells specifically into gut tissue.
Prescribing in practice
- Screen for tuberculosis and active infection before starting, and remain alert to infection during treatment despite its gut-selective action.
- Treatment usually begins with an intravenous induction schedule, with maintenance available intravenously or subcutaneously.
- Live vaccines should be avoided and immunisation status reviewed before initiation.
Monitoring
Monitor clinical response to guide continuation and watch for infusion reactions and signs of infection.
Counselling the patient
- Report fever or other signs of infection to your healthcare team.
- This medicine targets inflammation in the bowel rather than acting throughout the whole body.
- Tell your clinician before having any vaccinations.
Evidence & guidelines
NICE recommends vedolizumab as an option for treating moderately-to-severely active ulcerative colitis and Crohn's disease when other treatments have failed or are unsuitable.
