Ustekinumab Disease Interactions

There are 4 disease interactions with ustekinumab:

Major

Ustekinumab (Includes Ustekinumab) ↔ Infections

Severe Potential Hazard, Moderate plausibility

Applies to: Infection - Bacterial/Fungal/Protozoal/Viral

There have been reports of serious infections and reactivation of latent infections in patients receiving ustekinumab. Treatment with ustekinumab 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 ustekinumab in patients with a history of recurrent infections, underlying conditions which may predispose them to infections, or chronic, latent, or localized infections.

Major

Ustekinumab (Includes Ustekinumab) ↔ Malignancies

Severe Potential Hazard, Moderate plausibility

Applies to: 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.

Major

Ustekinumab (Includes Ustekinumab) ↔ Tuberculosis

Severe Potential Hazard, Moderate plausibility

Applies to: Tuberculosis -- Latent, Tuberculosis -- Active

Before initiating ustekinumab, patients should be screened for latent tuberculosis infection with a tuberculin skin test. Do not administer this agent to patients with an active tuberculosis infection. Patients testing positive in tuberculosis screening should be treated by standard medical practice prior to therapy with ustekinumab. Anti-tuberculosis therapy should be considered prior to initiation of ustekinumab 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.

Moderate

Ustekinumab (Includes Ustekinumab) ↔ Immunizations

Moderate Potential Hazard, Moderate plausibility

Applies to: 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

The classifications below are a general guideline only. It is difficult to determine the relevance of a particular drug interaction to any individual given the large number of variables.

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.

Do not stop taking any medications without consulting your healthcare provider.
