Cyltezo is administered as a subcutaneous injection, typically in the thigh or abdomen, although your healthcare provider will instruct you on the best injection site. Cyltezo can be self-administered at home after proper training from a healthcare professional. Here is how to use it:

1. Prepare the injection:
   • Wash your hands thoroughly before handling the injection.
   • Take the medication out of the refrigerator and allow it to come to room temperature for about 15-30 minutes.
   • Check the medication for any particles or discoloration. It should be clear and colorless or pale yellow. Do not use it if it appears cloudy or has visible particles.
2. Choose the injection site:
   • The recommended injection sites are the front of your thighs or your abdomen (avoiding the area 2 inches around your belly button). Choose a different injection site each time to reduce skin irritation.
3. Inject the medication:
   • Clean the injection site with an alcohol swab.
   • Remove the cap from the syringe or pen and hold it like a pencil.
   • Insert the needle at a 90-degree angle into the skin and push the plunger to administer the medication.
   • Once the medication is fully injected, remove the needle and apply pressure to the injection site with a clean cotton ball or gauze.
4. Dispose of the syringe:
   • Dispose of the syringe or pen in a sharps container immediately after use to prevent needle-stick injuries.

If you have any difficulty with the injection or experience side effects, consult your healthcare provider for guidance.

Cyltezo works by inhibiting TNF-alpha, which is a pro-inflammatory cytokine. TNF-alpha plays a significant role in the inflammatory processes of many autoimmune diseases. In conditions like rheumatoid arthritis, psoriasis, and inflammatory bowel disease, TNF-alpha is overactive, leading to tissue damage, pain, swelling, and other symptoms.

By binding to TNF-alpha, Cyltezo blocks its ability to bind to its receptors on cell surfaces, thereby reducing the inflammatory response in the body. This helps to alleviate symptoms, prevent disease progression, and reduce the risk of joint or tissue damage caused by chronic inflammation.

Because it targets and interferes with a specific part of the immune system, Cyltezo can be an effective treatment for a variety of inflammatory diseases that involve excessive or inappropriate immune system activity.

Like all medications, Cyltezo may cause side effects. Most side effects are related to the immune system’s response to the medication. Common side effects include:

• Injection Site Reactions: Redness, pain, or swelling at the injection site.
• Infections: Cyltezo can suppress the immune system, making it easier for infections to occur. Common infections include upper respiratory infections, sinus infections, and urinary tract infections.
• Headaches: Some patients report headaches after using Cyltezo.
• Nausea: Feeling sick to the stomach or vomiting can occur in some individuals.
• Fatigue: Some people may feel unusually tired or weak.
• Rashes or Skin Reactions: A rash may develop, especially in patients with psoriasis.

Serious side effects can occur, though they are less common. These include:

• Serious Infections: Cyltezo can increase the risk of serious infections, including tuberculosis (TB), fungal infections, or bacterial infections. Before starting treatment, patients are screened for TB.
• Cancer: There have been reports of increased risk of certain cancers, particularly lymphoma, in patients taking TNF inhibitors like Cyltezo.
• Heart Failure: Cyltezo may exacerbate heart failure in certain individuals. Those with a history of heart failure should be monitored closely.
• Liver Problems: In rare cases, Cyltezo may affect liver function, causing liver enzymes to increase.

If you experience any severe side effects or signs of infection, contact your doctor immediately.

Before starting Cyltezo, it’s important to be aware of the following warnings and precautions:

• Infections: Cyltezo can weaken the immune system, so it’s crucial to avoid exposure to infections. You may need to be tested for tuberculosis (TB) and other infections before starting Cyltezo.
• Cancer Risk: There is a potential increased risk of cancers, especially lymphomas and skin cancers. Inform your doctor if you have a history of cancer.
• Heart Conditions: People with heart failure or other heart conditions should use Cyltezo with caution, as it may worsen these conditions.
• Liver Function: Cyltezo may affect liver enzymes. Regular monitoring of liver function is recommended, especially in those with existing liver problems.
• Live Vaccines: Avoid receiving live vaccines while on Cyltezo treatment, as it may increase the risk of infection.

Make sure to follow your doctor’s instructions closely, and discuss any medical conditions you have before starting treatment.

Cyltezo may interact with certain medications, particularly those that affect the immune system. These include:

• Live vaccines: Cyltezo can reduce the effectiveness of live vaccines and increase the risk of infection. It is generally recommended to avoid live vaccines during treatment with Cyltezo.
• Other immunosuppressive drugs: Taking Cyltezo alongside other immunosuppressive medications (e.g., methotrexate, corticosteroids) can increase the risk of infections and other side effects.
• Other TNF inhibitors: Combining Cyltezo with other TNF inhibitors may increase the risk of serious side effects, such as infections.

Always inform your doctor about all medications you are taking, including over-the-counter drugs, vitamins, and herbal supplements, to avoid any potential interactions.

The dosage of Cyltezo depends on the condition being treated:

• Rheumatoid arthritis: Starting with 40 mg every two weeks.
• Crohn’s disease: Initial doses of 160 mg followed by 80 mg two weeks later, then 40 mg every two weeks.
• Psoriasis: Starting with 80 mg followed by 40 mg every two weeks.

Your healthcare provider will adjust the dosage based on your individual response and medical condition. Do not change the dosage without consulting your doctor.

Cyltezo is a prescription medication, and you will need a prescription from your healthcare provider to obtain it. Your doctor will assess your medical condition, review your treatment options, and determine if Cyltezo is appropriate for you. Cyltezo is often prescribed for chronic inflammatory conditions, and it is important to use it under medical supervision to monitor for side effects and ensure it is working effectively.
