Vedolizumab
About Vedolizumab
Vedolizumab is a prescription biologic medicine used to treat adults with moderate to severe active ulcerative colitis and Crohn's disease. By targeting inflammation directly in the digestive tract, this medicine helps control symptoms and works to bring about long-term relief from swelling and irritation. It is prescribed for patients who have not responded well to, or cannot tolerate, other standard treatments.
This medicine is taken on a regular schedule determined by your healthcare provider, either as an intravenous infusion or a subcutaneous injection. To achieve the best results, it is crucial to use this medicine consistently as directed, even when you feel completely healthy. Making dietary changes and managing your stress levels can also help support your gut health and improve treatment outcomes.
While many patients tolerate this medicine well, some may experience mild side effects such as common cold symptoms, headaches, or joint pain. However, you must contact your doctor immediately if you develop signs of a severe allergic reaction, high fever, or severe abdominal pain. Regular monitoring by your healthcare team will help ensure the medicine is working safely.
Do not take this if you have a severe active infection, such as active tuberculosis, unless your doctor has specifically evaluated and approved it. Before starting Vedolizumab, tell your doctor if you have a history of chronic or recurring infections, liver problems, or if you are scheduled to receive any vaccines. Your doctor will perform screening tests before your first dose to ensure it is safe for you to start.
This medicine can interact with other treatments that suppress your immune system, which can increase your risk of catching serious infections. It is important to discuss your current medications with your healthcare team, and consult your doctor if you are pregnant, planning to become pregnant, breastfeeding, or are an older adult. Avoid drinking alcohol or smoking, as these habits can further irritate your digestive tract and worsen your underlying condition.
Uses of Vedolizumab
Medicinal Benefits
Vedolizumab offers several benefits that help improve symptom control, support intestinal healing, and promote long-term disease management, including:
- Targeted action in the gut: Vedolizumab focuses its action specifically on the digestive tract rather than suppressing your body's entire immune system. This gut-selective approach helps manage chronic inflammation while reducing the likelihood of widespread, systemic side effects.
- Improved symptom control: By effectively lowering gut inflammation, many patients experience a significant reduction in active symptoms, leading to fewer daily bathroom visits and less abdominal discomfort. This symptom control helps you return to normal daily activities with greater confidence and comfort.
- Supports long-term intestinal healing: Consistent use of this medicine supports the physical healing of the intestinal lining over time. Achieving deep mucosal healing helps maintain long-term remission, lowering the risk of sudden flare-ups and reducing the likelihood of hospital stays or gut-related surgeries.
Directions for Use
- Follow your doctor’s instructions on the dosage and timing of this medication.

Habit Forming
Diet & Lifestyle Advise
- Track your food triggers: Keep a daily food diary to identify specific foods—such as spicy dishes, dairy, or high-fibre foods—that may worsen your digestive symptoms during flare-ups.
- Eat smaller, frequent meals: Consuming five or six small meals throughout the day instead of three large ones can reduce stress on your healing digestive tract.
- Stay well-hydrated: Drink plenty of water and clear broths, especially if you are experiencing diarrhoea, to prevent dehydration and help your body absorb nutrients.
- Manage stress: Chronic stress can trigger gut inflammation. Practice daily relaxation techniques such as deep breathing exercises, light yoga, or meditation to help manage your condition.
- Limit digestive irritants: Avoid carbonated drinks, caffeine, and artificial sweeteners, which can cause excess gas, bloating, and diarrhoea.
Special Advise
- It is advised to closely monitor the patient for infections like active tuberculosis during and after the treatment, though the patient gets a negative tuberculin test.
- It is essential to inform your doctor if you have any active viral, bacterial, and fungal infections before starting Vedolizumab.
Patients Concern
Disease/Condition Glossary
Ulcerative colitis: Ulcerative colitis is a serious inflammatory bowel disease causing inflammation in the digestive tract. It produces ulcers on the inner lining of the large intestine, which may cause bleeding and discharge of pus and mucus. The common symptoms include bloody stools, stomach pain, rectal pain, diarrhoea, fever, or weight loss. Additionally, it may cause other problems such as joint pain or swelling, mouth sores, skin problems, decreased appetite, or nausea.
Crohn’s disease: Crohn’s disease is a type of chronic inflammatory bowel disease that can affect any part of the gastrointestinal tract, from mouth to anus. But mostly occurs in the small intestine and large intestine. The symptoms include blood in stools, stomach cramps, tiredness, diarrhoea, fever, weight loss, or loss of appetite.
FAQs
Vedolizumab is used to treat Crohn’s disease and ulcerative colitis.
Vedolizumab works by binding to the chemical substance called α4β7 integrin, which is responsible for inflammation. This alters the gene expression of blood monocytes and thus helps reduce inflammation.
Inform your doctor about your complete medical and medication history, especially if you have any history of serious infections, tuberculosis, gastrointestinal disorders, liver or kidney diseases, or a weak immune system, as it can worsen your health condition.
The effects of Vedolizumab on pregnant women or breastfeeding infants are not fully known. If you are pregnant, planning to become pregnant, or breastfeeding, talk to your doctor to weigh the potential benefits of keeping your bowel disease in remission against the risks.
No, Vedolizumab is gut-selective, meaning it primarily blocks inflammatory cells from entering your digestive tract rather than suppressing your body's overall immune system. However, it can still slightly increase your risk of certain localized infections, so talk to your doctor if you have concerns.
Yes, but you must keep the medicine cold. Use a travel cooler bag with ice packs to keep the pre-filled syringes or pens at refrigerator temperature (2°C to 8°C) while on the go, and talk to your doctor or pharmacist about safe travel storage techniques.
Yes, your doctor will likely schedule regular checkups to monitor your response to the medicine. These may include blood tests to check your liver function and screens to ensure you have not developed any underlying infections. Talk to your doctor to learn more about your monitoring schedule.
You can receive non-live (inactivated) vaccines, but you should avoid receiving live vaccines, such as those for shingles or yellow fever, during your treatment. Always talk to your doctor before receiving any vaccine to make sure it is safe.
Mild redness, itching, swelling, or pain at the injection site is common and usually resolves on its own within a few days. If the reaction is severe, painful, spreads, or does not improve, talk to your doctor immediately.
There is no direct chemical interaction between alcohol and Vedolizumab. However, alcohol can irritate your digestive tract, trigger gut inflammation, and worsen your underlying Crohn's or colitis symptoms, so talk to your doctor about your alcohol consumption.
