  • Avoid concomitant use of Cibinqo with strong CYP2C19 or CYP2C9 inducers.
  • Monitor appropriately or dose titrate P-gp substrate where small concentration changes may lead to serious or life-threatening toxicities when coadministered with CIBINQO.

What special precautions should I follow?[edit | edit source]

  • The most frequent serious infections reported in clinical studies with Cibinqo for atopic dermatitis were herpes simplex, herpes zoster, and pneumonia. Avoid use of Cibinqo in patients with active, serious infection including localized infections.
  • Treatment with Cibinqo was associated with an increased incidence of hematologic abnormalities and lipid elevations. Laboratory monitoring is recommended due to potential changes in platelets, lymphocytes, and lipids.
  • Prior to initiating CIBINQO, complete all age-appropriate vaccinations as recommended by current immunization guidelines including prophylactic herpes zoster vaccinations. Avoid use of live vaccines prior to, during, and immediately after Cibinqo treatment.
  • In a large, randomized, postmarketing safety study of another JAK inhibitor in rheumatoid arthritis (RA) patients 50 years of age and older with at least one cardiovascular risk factor, a higher rate of all-cause mortality, including sudden cardiovascular death, was observed in patients treated with the JAK inhibitor compared with TNF blockers. Consider the benefits and risks for the individual patient prior to initiating or continuing therapy with CIBINQO.
  • Malignancies, including non-melanoma skin cancer (NMSC), were observed in clinical studies with Cibinqo for atopic dermatitis. Perform periodic skin examination for patients who are at increased risk for skin cancer. Exposure to sunlight and UV light should be limited by wearing protective clothing and using broad-spectrum sunscreen.
  • Major adverse cardiovascular events were reported in clinical studies of Cibinqo for atopic dermatitis. Consider the benefits and risks for the individual patient prior to initiating or continuing therapy with CIBINQO.
  • Deep venous thrombosis (DVT) and pulmonary embolism (PE) were observed in patients receiving CIBINQO. Avoid Cibinqo in patients that may be at increased risk of thrombosis. If symptoms of thrombosis occur, discontinue Cibinqo and evaluate and treat patients appropriately.
