Your doctor will test you for active or latent tuberculosis (TB) before you start treatment with Ilumya. People with latent TB may not know they have the infection because there are often no symptoms. A blood test is the only way to know if someone with latent TB is infected.
Testing for TB before treatment with Ilumya is important because Ilumya weakens the immune system. When the immune system is weakened, it can’t fight off infections, and latent TB can become active. Symptoms of active TB include fever, fatigue, weight loss, coughing up blood, and chest pain.
If you test positive for TB, you’ll likely need to receive TB treatment before starting Ilumya.
