Ustekinumab
About Ustekinumab
Ustekinumab is a prescription injection used to treat chronic inflammatory conditions, including moderate to severe plaque psoriasis, active psoriatic arthritis, Crohn's disease, and ulcerative colitis. By targeting specific pathways in the immune system, it helps calm overactive inflammation that affects your skin, joints, or digestive tract.
To get the best results, it is important to take this medicine consistently as prescribed by your healthcare provider. Because it is given as an injection, food intake does not affect how it works. Making certain lifestyle adjustments, such as managing your daily stress levels and eating a nutrient-dense diet, can also support your treatment journey.
While this medicine is generally well-tolerated, some people may experience mild side effects like cold-like symptoms, headaches, or redness at the injection site. However, serious side effects such as severe infections or severe allergic reactions can occur. You must consult your doctor immediately if you experience a high fever, severe cough, or difficulty breathing.
Talk to your doctor before starting Ustekinumab if you have any active infections, a history of tuberculosis, or a weakened immune system. Do not take this if you are currently suffering from a serious, active infection or if you have had a severe allergic reaction to this medicine in the past.
This medicine may interact with other treatments, especially those that suppress the immune system, and live vaccines must be avoided. If you are pregnant, breastfeeding, or planning a pregnancy, consult your doctor or pharmacist to weigh the benefits and risks before starting treatment.
Uses of Ustekinumab
Medicinal Benefits
When used as directed as part of your treatment plan, Ustekinumab may provide the following benefits:
- Improves skin symptoms: In plaque psoriasis, Ustekinumab can reduce the redness, scaling, thickness, and itching of plaques, improving skin comfort and making symptoms easier to manage.
- Improves joint symptoms and movement: In psoriatic arthritis, reducing inflammation can ease joint pain, swelling, and stiffness, helping you move more comfortably and carry out daily activities.
- Helps control bowel symptoms: In Crohn's disease and ulcerative colitis, reducing inflammation can improve symptoms such as diarrhoea, abdominal pain, rectal bleeding, and bowel urgency, depending on the condition.
- Supports longer-term symptom control: In people who respond to treatment, maintenance therapy can help sustain improvement and maintain remission in Crohn's disease or ulcerative colitis.
Directions for Use
- Follow your doctor’s recommendations for the correct dosage and timing of this medication.
- Ustekinumab comes in a prefilled syringe to be given by a healthcare professional; if you are well-trained and advised by your doctor to administer Ustekinumab at home, follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand.

- Inspect before injecting: Check the appearance of the solution every single time; it must be clear or slightly pearly, and never cloudy or discoloured.
- Rotate your injection sites: Inject in a different spot each time (thigh, abdomen, or outer upper arm) to prevent skin irritation or thickening.
- Avoid damaged skin: Never inject into skin areas that are bruised, tender, red, hard, or actively affected by psoriasis plaques.

Drug Interactions
- Immunosuppressive medicines: Taking Ustekinumab with other drugs that lower your immune system can significantly increase your risk of developing a serious infection.
- Live vaccines: Combining this medicine with live viral or bacterial vaccines may cause the vaccine to trigger an actual infection instead of providing immunity.

Habit Forming
Diet & Lifestyle Advise
- Track your food: If you are treating Crohn's or ulcerative colitis, keep a daily food journal to identify and avoid personal trigger foods that can worsen inflammation.
- Eat anti-inflammatory foods: Focus on a balanced diet rich in leafy greens, berries, and healthy fats like olive oil and wild-caught fish, which naturally help manage systemic inflammation.
- Choose low-impact exercises: For joint pain from psoriatic arthritis, engage in gentle activities like swimming, stationary cycling, or yoga to keep your joints flexible without causing strain.
- Moisturise your skin regularly: If you have psoriasis, apply thick, fragrance-free moisturisers immediately after bathing to lock in moisture and protect your skin barrier.
- Avoid smoking: Smoking can significantly reduce the effectiveness of your treatment and is a known trigger for both psoriasis flares and severe bowel inflammation.
Patients Concern
Disease/Condition Glossary
Ulcerative colitis: Ulcerative colitis is a type of chronic inflammatory bowel disease that causes inflammation of the lining of the large intestine (colon) and produces ulcers on the lining of the colon, which may cause bleeding and discharge of pus and mucus. The common symptoms include bloody stools, stomach pain, rectal pain, diarrhoea, and fever or weight loss. Additionally, it may cause other problems such as joint pain or swelling, mouth sores, skin problems, decreased appetite or nausea. The factors involved in causing ulcerative colitis include immune disorders and environmental factors like viruses, bacteria or antigens, which may trigger the immune system and genes inherited from the parent.
Crohn's disease: Crohn's disease is a chronic inflammatory disorder that affects the digestive tract. It is a kind of inflammatory bowel disease (IBD). The most common symptoms are diarrhoea, stomach aches and cramps, blood in your poo, exhaustion (fatigue), and weight loss.
Psoriasis: Psoriasis is a chronic autoimmune skin condition in which the skin multiplies ten times faster than usual. This causes a rapid accumulation of skin cells, resulting in scaling on the skin's surface. Inflamed, red, elevated areas of skin, soreness surrounding the patches, itching, burning feeling, swollen joints, and dry skin are all symptoms.
Psoriatic arthritis: Psoriatic arthritis is an arthritis that is associated with psoriasis, a persistent skin and nail disease.
