Cosentyx® Injection for Plaque Psoriasis

Cosentyx is a prescription biologic for plaque psoriasis and related conditions. This page explains what it treats, how to use it, and safety basics. You can request refills with US delivery from Canada, and review the Cosentyx cost without insurance.

What Cosentyx Is and How It Works

Cosentyx® contains secukinumab, a monoclonal antibody that targets interleukin‑17A (IL‑17A). By blocking IL‑17A, it helps calm overactive inflammation in skin and joints. The medication is supplied for self-injection as single-use devices, including the Cosentyx Sensoready Pen. YouDrugstore is a licensed Canadian pharmacy in Manitoba. Pharmacists review prescriptions before dispensing.

This treatment is approved for adults with moderate to severe plaque psoriasis. It is also indicated for psoriatic arthritis and axial spondyloarthritis, including ankylosing spondylitis and non‑radiographic disease. Pediatric plaque psoriasis use is approved for certain ages. For an overview of the skin condition it treats, see our guide to Plaque Psoriasis. You can also read community stories during World Psoriasis Day.

Who It’s For

This medicine may be suitable for adults with moderate to severe plaque psoriasis who need systemic therapy or phototherapy. It is also used for active psoriatic arthritis, with or without psoriasis, and for adults with axial spondyloarthritis. Some children with plaque psoriasis may also receive it when approved by their prescriber.

People with an active infection should not start this therapy. Those with chronic or recurrent infections, or a history of tuberculosis, need careful screening and monitoring. Individuals with inflammatory bowel disease may experience worsening symptoms and should discuss risks. People with known serious allergy to secukinumab or any component should not use it.

Dosage and Usage

Your prescriber will set your schedule based on your condition and response. Many patients begin with a weekly starter series followed by maintenance doses taken every month. For certain diagnoses, some people may use two injections on the same day of their maintenance schedule.

Prescribers sometimes choose Cosentyx 150 mg for individual needs. After a starting phase, ongoing use typically follows a regular monthly rhythm to help maintain control. Continue on the day assigned by your clinician to keep consistency. If many weeks pass between doses, your prescriber may reassess your plan.

Give injections subcutaneously in the thigh, abdomen, or back of the upper arm if someone else administers it. Rotate sites. Do not inject into areas that are tender, bruised, scaly, or infected. Inspect the solution. Do not use if the liquid is cloudy, discolored, or contains particles.

Not all presentations are always in stock. Device type may differ between first fill and refills depending on supply.

Missed Dose and Timing

If you miss a scheduled injection, take it as soon as you remember. Then take your next dose on the original day if possible. If the timing is unclear, contact your healthcare professional or see the official prescribing information. Avoid doubling doses to make up for a missed injection.

Storage and Travel Basics

Store in a refrigerator in the original carton to protect from light. Do not freeze. Do not shake. Before injecting, allow the device to reach room temperature out of the carton for the recommended warm-up time. If needed, limited time at room temperature is permitted per the official label; do not return it to the refrigerator once kept at room temperature.

For travel, keep the carton in insulated packaging with cold packs, avoiding direct contact with the device. Place the medicine in your carry-on. Bring your prescription label and a copy of your instructions from your prescriber in case security staff ask for documentation. Keep it out of reach of children and pets.

Pen Handling and Sharps Disposal

Let the pen or syringe warm up on a clean surface. Wash and dry your hands. Clean the injection site with an alcohol swab. With an autoinjector, place it flat against the skin and trigger as directed. Hold in place for the full time in your instructions. With a syringe, pinch the skin and inject at the angle taught by your clinician. Do not recap needles. Place used devices in an approved sharps container. Follow local rules for disposal; pharmacies can advise on disposal options.

Benefits

This therapy helps reduce plaque thickness, scaling, and redness. Many people experience less itch and improved comfort in difficult areas such as the scalp. Those with joint symptoms may notice reduced tenderness and stiffness. A monthly maintenance rhythm can be convenient once you have completed the starter phase. At-home injection also supports consistent use without frequent clinic visits.

Side Effects and Safety

• Upper respiratory infections, like a cold
• Headache or fatigue
• Diarrhea
• Nasal congestion or sore throat
• Injection-site redness or pain

Serious risks can include severe infections, reactivation of tuberculosis, and allergic reactions with swelling or hives. Inflammatory bowel disease may worsen in some people. Seek urgent care for signs of severe allergy or infection such as high fever, chills, or shortness of breath. Your prescriber may screen for tuberculosis before starting therapy.

Drug Interactions and Cautions

Avoid live vaccines while using this biologic. Tell your prescriber about all medicines you take, including immunosuppressants, corticosteroids, and biologics, as using multiple agents may raise infection risk. Report any history of inflammatory bowel disease, recurrent infections, or recent vaccination. The needle cap on some devices contains a natural rubber latex derivative; people with latex sensitivity should discuss alternatives.

What to Expect Over Time

Your response can vary. Some people notice skin changes after the starter phase, while others take longer. Sticking to your schedule is important for steady results. Keep regular check-ins with your clinician to review progress and tolerability. If your condition changes, your prescriber may adjust your plan according to the official label and your medical history.

Compare With Alternatives

Other prescription biologics for psoriasis and psoriatic arthritis include IL‑17, IL‑23, and IL‑12/23 inhibitors. IL‑17A blockade is also available as Taltz, which uses a different antibody. An IL‑12/23 option is Stelara Prefilled Syring. Your prescriber will help choose based on diagnosis, comorbidities, prior response, and injection preferences.

Availability and Substitutions

Supply can vary by device and package size. This biologic does not have an interchangeable generic.

We cannot provide restock dates, but you can check back or consult your clinician about options.

Patient Suitability and Cost-Saving Tips

Good candidates are those with moderate to severe plaque psoriasis or psoriatic arthritis who have discussed risks and benefits with their prescriber. People with active serious infection or a history of severe allergy to any component should not use it. Those with inflammatory bowel disease need careful discussion about risks.

To manage out-of-pocket costs, consider:

• Multi-month fills to reduce per-order fees
• Refill reminders to avoid gaps in therapy
• Coordinating visits and lab work on a consistent schedule
• Choosing the device your clinician recommends for home use
