What is Olumiant?
Olumiant blocks the activity of certain enzymes involved in activating inflammation in the body.
Olumiant is used to reduce pain, stiffness, and swelling in adults with rheumatoid arthritis after other treatments have failed. Olumiant also helps slow the progression of bone and joint damage.
Olumiant is used in adults who are hospitalized with COVID-19 requiring oxygen or assistance with breathing.
Olumiant is also used to treat adults with severe alopecia areata.
Olumiant affects your immune system. You may get infections more easily, even serious or fatal infections. Call your doctor if you have a fever, chills, aches, tiredness, cough, skin sores, diarrhea, weight loss, or burning when you urinate.
Tell your doctor if you have a weak immune system, diabetes, chronic lung disease, or an infection such as hepatitis, tuberculosis, shingles, or HIV. Also tell your doctor if you've ever had diverticulitis, an ulcer in your stomach or intestines, cancer, heart problems, or a history of smoking, heart attack, stroke, or blood clots.
Call your doctor right away if you have a fever, night sweats, constant tiredness, weight loss, stomach pain, diarrhea or changes in bowel habits, trouble breathing, wheezing, a severe cough, or lumps in your neck, armpits, or groin.
Seek emergency medical help if you have sudden shortness of breath, chest pain spreading to your neck or arms, nausea, severe dizziness, a cold sweat, weakness on one side of your body, slurred speech, or pain, redness, or swelling in an arm or leg.
You should not start taking Olumiant if you have any kind of infection. Your doctor may perform tests to make sure you do not have tuberculosis or other infections.
