Precautions while using infliximab-qbtx

It is very important that your doctor checks your or your child's progress at regular visits to ensure that this medicine is working properly. Blood tests may be needed to check for unwanted effects.

Infliximab-qbtx may cause an infusion reaction while you are receiving it or right after the infusion ends. Check with your doctor or nurse right away if you experience chest pain, fever, chills, itching, hives, rash, dizziness, fainting, lightheadedness, headache, joint pain, difficulty swallowing, shortness of breath, trouble breathing, or swelling of the face, tongue, and throat.

Your body's ability to fight infections may be reduced while you are using infliximab-qbtx. It is very important to call your doctor at the first sign of any infection. Check with your doctor right away if you have a fever, chills, cough, flu-like symptoms, or unusual tiredness or weakness.

You will need to have a skin test for tuberculosis before you start receiving this medicine. Tell your doctor if you or anyone in your home has ever had a positive reaction to a tuberculosis skin test.

A small number of people (including children and teenagers) who have used this medicine have developed certain types of cancer. This is more common in patients with lung diseases (e.g., emphysema, COPD) or heavy smokers, and in psoriasis patients who have had phototherapy treatment for a long time. Phototherapy treatment is ultraviolet light or sunlight combined with oral medicine to make your skin sensitive to light. Some teenagers and young adults with Crohn disease or ulcerative colitis have also developed a rare type of cancer called hepatosplenic T-cell lymphoma. Talk with your doctor if you have unusual bleeding, bruising, or weakness, swollen lymph nodes in the neck, underarms, or groin, unexplained weight loss, or red, scaly patches, or raised bumps with pus on the skin.

Receiving this medicine may increase your risk of developing skin cancer (e.g., melanoma, Merkel cell carcinoma) or cervical cancer. If you notice any changes or growths on your skin, abnormal vaginal bleeding, or pelvic pain, check with your doctor right away.

It is important to have your heart monitored closely if you receive infliximab-qbtx. Call your doctor right away if you experience difficulty breathing, swelling in the ankles and feet, or sudden weight gain.

Serious skin reactions can occur while you are receiving this medicine. Check with your doctor right away if you have blistering, peeling, or loosening of the skin, chills, cough, diarrhea, fever, itching, joint or muscle pain, red skin lesions, sore throat, sores, ulcers, or white spots in your mouth, or unusual tiredness or weakness.

This medicine may increase your chance of having a lupus-like syndrome or a liver disease called autoimmune hepatitis. Check with your doctor right away if you have dark brown-colored urine, fever or chills, a general feeling of discomfort, illness, or weakness, joint pain, light-colored stools, nausea and vomiting, a rash on the cheeks or arms that worsens in the sun, severe tiredness, upper right-sided stomach pain, or yellow eyes and skin.

While you are being treated with infliximab-qbtx, do not receive any immunizations (vaccines) without your doctor's approval. Live virus vaccines should not be given with infliximab-qbtx. Your child's vaccinations must be current before receiving infliximab-qbtx. Talk to your child's doctor if you have any questions about this.

Women: If you have a baby while receiving infliximab-qbtx, make sure the baby's doctor knows that you were receiving this medicine. You will need to wait a few months before giving certain vaccines to your baby. Talk to the baby's doctor if you have questions.

Do not take other medicines unless they have been discussed with your doctor. This includes abatacept (Orencia®), anakinra (Kineret®), tocilizumab (Actemra®), or other medicines called biologics that are used to treat the same conditions as infliximab-qbtx. Using these medicines together with infliximab-qbtx may increase your chance of having serious unwanted effects.

Before using infliximab-qbtx

In deciding to use a medicine, you and your doctor need to think about the risks of taking the medicine compared to the benefits it may provide. The following should be considered for this medicine:

Allergies

Let your doctor know if you have ever had any unusual or allergic reactions to this medicine or any other medicines. Also, inform your healthcare professional about any other allergies you may have, including allergies to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.

Pediatric

Studies done so far have not shown any pediatric-specific issues that would limit the use of infliximab-qbtx injection for treating Crohn disease or ulcerative colitis in children 6 years of age and older. However, safety and effectiveness have not been established in children younger than 6 years old.

Studies have shown that infliximab-qbtx injection is not effective in children with juvenile rheumatoid arthritis. Effectiveness has not been proven.

Studies have not been conducted to understand how age affects the use of infliximab-qbtx injection for treating ankylosing spondylitis, psoriatic arthritis, and chronic severe plaque psoriasis in children. Safety and effectiveness have not been established.

Geriatric

Studies conducted so far have not shown any specific problems for elderly patients that would limit the use of infliximab-qbtx injection. However, older adults are more likely to have infections, which may require caution when receiving infliximab-qbtx injection.

Breast Feeding

There are no adequate studies in women to determine the risk to infants when using this medication while breastfeeding. Consider the potential benefits and risks before taking this medication during breastfeeding.
