Stelara (ustekinumab) Disease Interactions

There are 5 disease interactions with Stelara (ustekinumab):


Ustekinumab (applies to Stelara) malignancies

Major Potential Hazard, Moderate plausibility. Applicable conditions: Skin Cancer

In clinical trials malignancies have been observed in patients receiving ustekinumab. Patients should be monitored for non-melanoma skin cancers (NMSCs), particularly those patients who have had prior prolonged phototherapy treatment. Periodic skin examination is recommended for all patients, particularly those with risk factors for skin cancer. Caution should be exercised when considering ustekinumab for the treatment of patients with a history of malignancy, those who have a known malignancy, or in continuing treatment in patients who develop malignancy while receiving this agent.


Ustekinumab (applies to Stelara) posterior leukoencephalopathy syndrome

Major Potential Hazard, Moderate plausibility. Applicable conditions: Posterior Reversible Encephalopathy Syndrome, Pre-eclampsia/Eclampsia, Hypertension, Immunodeficiency

The use of ustekinumab may cause posterior leukoencephalopathy syndrome. One case of reversible posterior leukoencephalopathy syndrome (RPLS) was observed in clinical studies of psoriasis and psoriatic arthritis. No cases of RPLS were observed in clinical studies of Crohn's disease. Conditions with which it has been associated include preeclampsia, eclampsia, acute hypertension, cytotoxic agents and immunosuppressive therapy. Caution and close monitoring is advised when prescribing this agent to patients at risk of RPLS. It is recommended to administer appropriate treatment and discontinue therapy if RPLS is suspected.


Interleukin inhibitors (applies to Stelara) infections

Moderate Potential Hazard, Moderate plausibility. Applicable conditions: Infection - Bacterial/Fungal/Protozoal/Viral

There have been reports of serious infections, including infections with opportunistic pathogens, and reactivation of latent infections in patients receiving interleukin inhibitors. Treatment with these agents should not be initiated in patients with an active infection until the infection resolves or is adequately treated. Caution is recommended when considering the use of interleukin inhibitors in patients with a history of recurrent infections, underlying conditions which may predispose them to infections, or chronic, latent, or localized infections.


Interleukin inhibitors (applies to Stelara) tuberculosis

Moderate Potential Hazard, Moderate plausibility. Applicable conditions: Tuberculosis -- Latent, Tuberculosis -- Active, History - Tuberculosis

Before initiating certain interleukin inhibitors, patients should be screened for latent tuberculosis infection with a tuberculin skin test. Do not administer these agents to patients with an active tuberculosis infection. Patients testing positive in tuberculosis screening should be treated by standard medical practice prior to therapy. Anti-tuberculosis therapy should be considered prior to initiation of therapy in patients with a past history of latent or active tuberculosis in whom an adequate course of treatment cannot be confirmed, and for patients with a negative test for latent tuberculosis but having risk factors for tuberculosis infection.


Ustekinumab (applies to Stelara) immunizations

Moderate Potential Hazard, Moderate plausibility. Applicable conditions: Vaccination

Patients requiring non-live vaccination during a course of ustekinumab may not be protected from the vaccine as the immune response might not be sufficient to prevent the disease. It is recommended to be up-to-date with all required immunizations, as recommended by current immunization guidelines, before initiating therapy with ustekinumab. BCG vaccines should not be given during treatment with ustekinumab or for one year prior to initiating treatment or one year following discontinuation of treatment. Caution is advised when administering live vaccines to household contacts of patients receiving ustekinumab because of the potential risk for shedding from the household contact and transmission to patient.

Drug Interaction Classification

These classifications are only a guideline. The relevance of a particular drug interaction to a specific individual is difficult to determine. Always consult your healthcare provider before starting or stopping any medication.
Major Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit.
Moderate Moderately clinically significant. Usually avoid combinations; use it only under special circumstances.
Minor Minimally clinically significant. Minimize risk; assess risk and consider an alternative drug, take steps to circumvent the interaction risk and/or institute a monitoring plan.
Unknown No interaction information available.
