Discontinue treatment in patients w/ suspected VTE, regardless of dose; if platelet counts are <50 x 10
3/mm
3. Interrupt treatment if absolute lymphocyte count (ALC) is <0.5 x 10
3/mm
3, ANC is <1 x 10

3, or Hb is <8 g/dL; temporarily if patient is not responding to standard therapy; develops herpes zoster. Consider dose interruption if patient develops serious infection, sepsis or opportunistic infection. Not to be initiated in patients w/ active, serious systemic infection; platelet count <150 x 10

3 or Hb <10 g/dL. Not to be given in patients w/ active TB. Serious infections eg, herpes simplex, herpes zoster & pneumonia; viral reactivation, including herpes virus reactivation; DVT & pulmonary embolism; lymphoma & other malignancies; non-melanoma skin cancer; MACE; dose-dependent increase in blood lipid parameters. Monitor patients w/ abnormal lipid parameters. Patients w/ history of atherosclerotic CV disease or other CV risk factors (eg, current or past long-time smokers); malignancy risk factors (eg, current or history of malignancy); diabetes (higher incidence of infections); medical history of herpes zoster, confirmed ALC <1 x 10
3/mm
3 prior to treatment, severe atopic dermatitis at baseline; known VTE risk factors other than malignancy & CV risk factors eg, previous VTE, major surgery, immobilisation, use of combined hormonal contraceptives or HRT, inherited coagulation disorder. Consider risks & benefits of treatment prior to initiation in patients w/ chronic or recurrent infection, history of serious or opportunistic infection, underlying conditions that may predispose to infection; who have been exposed to TB, resided or travelled in areas of endemic TB or endemic mycoses. Closely monitor patients for development of signs & symptoms of infection during & after treatment. Screen patients for TB before starting treatment & yrly if in highly endemic areas for TB. Prompt & complete diagnostic testing & initiate appropriate antimicrobial therapy in patient who develops new infection during treatment. Start preventive therapy for latent TB prior to treatment initiation in patients w/ new diagnosis of latent TB or prior untreated latent TB. Perform screening for viral hepatitis before & during therapy; periodic skin exam for all patients particularly those at increased risk for skin cancer. Evaluate patients w/ signs & symptoms of VTE & re-evaluate periodically to assess for changes in VTE risk. Monitor CBC 4 wk after therapy initiation & thereafter according to routine patient management. Assess lipid parameters approx 4 wk following therapy initiation & thereafter according to CV disease risk. Update all immunizations including prophylactic herpes zoster vaccinations prior to treatment initiation. Not to be taken by patients w/ galactose intolerance, total lactase deficiency or glucose galactose malabsorption. Avoid use of live, attenuated vaccines during or immediately prior to treatment. Not recommended to use concomitantly w/ biologic immunomodulators, potent immunosuppressants eg, ciclosporin or other Janus kinase inhibitors; moderate or strong CYP2C19/CYP2C9 enzyme inducers eg, rifampicin, apalutamide, efavirenz, enzalutamide, phenytoin. ESRD patients on renal replacement therapy. Women of childbearing potential should use effective contraception during treatment & 1 mth after final dose. Childn <12 yr. Elderly ≥65 yr.
