Precautions

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

This medicine may cause you to get infections more easily (eg, mouth, skin, or upper respiratory tract infections). It is important to check with your doctor if you have fever or chills, cough or hoarseness, lower back or side pain, painful or difficult urination, runny or stuffy nose, skin itching or scaling, or sores or white patches on your lips, mouth, or throat.

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

Inflammatory bowel disease may occur while you are using this medicine. Tell your doctor right away if you have rectal bleeding, severe stomach pain, or severe diarrhea while using this medicine.

This medicine may cause serious skin reactions, including atopic dermatitis-like eruptions, dyshidrotic eczema, and erythroderma. Check with your doctor right away if you have blistering, crusting, dryness, irritation, itching, peeling, redness, scaling, or swelling of the skin.

This medicine may cause serious allergic reactions including anaphylaxis, which can be life-threatening and requires immediate medical attention. Call your doctor right away if you have a rash, itching, trouble breathing, trouble swallowing, or any swelling of your hands, face, or mouth while you are using this medicine.

While you are being treated with secukinumab, and after you stop treatment with it, do not have any immunizations (vaccines) without your doctor's approval. Secukinumab may lower your body's resistance and the vaccine may not work as well or you might get the infection the vaccine is meant to prevent. In addition, you should not be around other persons living in your household who receive live virus vaccines because there is a chance they could pass the virus on to you. Some examples of live vaccines include measles, mumps, influenza (nasal flu vaccine), poliovirus (oral form), rotavirus, and rubella. Do not get close to them and do not stay in the same room with them for very long. If you have questions about this, talk to your doctor.

Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal or vitamin supplements.
