Stelara® Prefilled Syringe for Immune-Mediated Inflammatory Conditions

What Stelara® Is and How It Works

Stelara (ustekinumab) is a biologic medicine for plaque psoriasis, psoriatic arthritis, Crohn’s disease, and ulcerative colitis. It blocks interleukin‑12 and interleukin‑23 pathways to reduce inflammation. YouDrugstore is a licensed Canadian pharmacy headquartered in Manitoba; prescriptions are reviewed by licensed pharmacists before dispensing. You can buy Stelara Prefilled Syring online through our secure checkout, even without insurance. We work with licensed, vetted partner pharmacies worldwide to supply authentic brand medicines, a wide selection, and affordable pricing.

Stelara is supplied as prefilled syringes for subcutaneous injection. Common strengths are 45 mg and 90 mg. In Crohn’s disease and ulcerative colitis, the first dose is often an intravenous infusion in a clinic, followed by at‑home subcutaneous injections using prefilled syringes. For psoriasis and psoriatic arthritis, treatment starts with subcutaneous injections and follows a maintenance schedule. This cadence helps keep symptoms controlled between doses.

Stelara offers infrequent dosing compared with many biologics. That can simplify your treatment plan. If you manage Crohns Disease, psoriatic arthritis, or plaque psoriasis, your prescriber will choose a schedule that fits your condition and body weight.

Dosage and Usage

• Psoriasis and psoriatic arthritis: subcutaneous injections at week 0 and week 4, then every 12 weeks. Doses are 45 mg for many adults up to 100 kg and 90 mg for those over 100 kg, as directed by your prescriber.
• Crohn’s disease and ulcerative colitis: a single weight‑based intravenous induction dose in clinic, then 90 mg subcutaneous at week 8, followed by 90 mg every 8 weeks for maintenance, as directed.
• Missed dose: take the missed injection when remembered. Then resume your regular schedule. Do not take two doses at once. If you are unsure how to adjust, ask your prescriber.
• Injection sites: abdomen, thigh, or upper arm. Rotate sites to avoid irritation and do not inject into tender, bruised, or scarred areas.
• Prefilled syringe steps: remove from the refrigerator and allow to warm to room temperature for about 30 minutes. Do not heat or shake. Check the solution; it should be clear to slightly yellow and free of large particles. Clean the skin with an alcohol swab. Pinch the skin and inject subcutaneously as trained. Dispose of the used syringe in a sharps container.

• Storage: keep in the refrigerator at 2–8 °C (36–46 °F). Do not freeze or shake. Keep in the original carton to protect from light.
• Room‑temperature allowance: if needed, one syringe may be kept at room temperature up to 30 °C (86 °F) for a single period of up to 30 days. Do not return it to the refrigerator. If not used within 30 days, discard.
• Travel: carry your syringes in an insulated bag with cool packs, not directly touching ice. Keep away from direct sunlight. Pack a copy of your prescription for security checks.
• Handling: do not use if the syringe is dropped, cracked, or the liquid looks cloudy or contains large particles. Keep out of reach of children.

Benefits and Savings

Stelara helps reduce plaques, joint pain and swelling, and gut inflammation. Many people notice steadier control thanks to an every‑8‑to‑12‑weeks cadence. The prefilled syringe makes self‑injection straightforward once you are trained. For Crohn’s disease and ulcerative colitis, maintenance injections help sustain remission after IV induction.

Ordering from a Canadian online pharmacy can lower your Stelara Prefilled Syring cost. Typical savings are 60–80% compared with many US prices. This may help if you are paying cash or managing therapy without insurance. Multi‑month supplies and bulk promotions can further reduce the per‑month price.

Side Effects and Safety

• Common: headache, fatigue, runny nose or sore throat, cough, diarrhea, nausea, back pain.
• Skin: injection site redness, itching, tenderness, small bruises.
• Infections: colds and sinus infections are reported; wash hands often and avoid close contact with people who are ill.
• Allergy: rash or hives can occur; seek urgent care for swelling of the face or trouble breathing.

Serious risks include severe infections (such as tuberculosis), rare hypersensitivity reactions, and a possible increased risk of some cancers over time. Your prescriber may test for latent TB before starting. Avoid live vaccines during treatment. Contact your healthcare professional promptly if you develop fever, persistent cough, weight loss, night sweats, severe headache, vision changes, or confusion.

Onset Time

For plaque psoriasis, some people see improvement within 2–4 weeks, with clearer skin often building through 8–12 weeks after the second injection. For psoriatic arthritis, joint symptoms may ease within the first month and continue to improve through 3 months.

In Crohn’s disease and ulcerative colitis, initial response often follows the IV induction within 3–6 weeks. Maintenance injections at week 8 and every 8 weeks thereafter support sustained response. Your results and timing may vary based on disease severity, prior therapies, and dose.

Compare With Alternatives

Humira (adalimumab) is a tumor necrosis factor (TNF) inhibitor used for similar conditions. It is typically injected every 2 weeks and may work quickly for joints and skin, but dosing is more frequent. You can review pricing and formats for Humira® to compare schedules and costs.

Skyrizi (risankizumab) targets IL‑23 only. For psoriasis, it is given at weeks 0 and 4, then every 12 weeks. For Crohn’s disease, it has an IV induction and subcutaneous maintenance. Compare options by visiting Skyrizi® Pre Fill Cartridge W Injector for details on its dosing and device.

Other options include Rymti (etanercept biosimilar) and conventional agents such as methotrexate for joints or aminosalicylates for mild bowel disease. Your prescriber will match the mechanism and dosing to your condition and history.

Combination Therapy

• Psoriatic arthritis: may be used with methotrexate to improve joint control, as directed.
• Skin disease: topical steroids or vitamin D analogs can be used for localized plaques.
• Inflammatory bowel disease: short steroid courses may bridge until Stelara maintenance takes effect; taper as advised.
• Do not combine with other biologic immunomodulators unless your specialist directs it.
• Keep vaccinations current before starting; avoid live vaccines during treatment.

Patient Suitability and Cost-Saving Tips

Stelara may be suitable for adults with moderate to severe plaque psoriasis, active psoriatic arthritis, or moderate to severe Crohn’s disease or ulcerative colitis. It can be considered after other treatments or as a first biologic depending on your case. People with current serious infections, untreated latent tuberculosis, or severe allergy to any component should not use it. The needle cover on some syringes contains latex; tell your clinician if you have a latex allergy.

Before starting, inform your prescriber about prior biologics, recent vaccines, and all medicines you take. Discuss pregnancy and breastfeeding plans. Regular monitoring may include infection screening and assessments of symptom control.

To manage costs, compare your Stelara Prefilled Syring price across package sizes. Ask about multi‑month orders to lower the monthly average. Turn on reorder reminders so you do not miss scheduled injections. If you pay cash or are uninsured, Canadian pricing can help, and promotions may reduce the upfront payment.
