Interactions between your drugs

Major

thalidomide ritlecitinib

Applies to: thalidomide and ritlecitinib

GENERALLY AVOID: Coadministration of ritlecitinib with other immunosuppressive agents may potentiate the risk of infections as well as malignancies, including non-melanoma skin cancer (NMSC). Serious infections have been reported in patients who have received ritlecitinib. The most common serious infections reported with ritlecitinib included appendicitis, pneumonia, COVID-19, and sepsis. Herpes virus reactivation (e.g., herpes zoster) was also reported during clinical studies with ritlecitinib, as well as malignancies including NMSC.

MANAGEMENT: The safety and efficacy of ritlecitinib in combination with immunosuppressive agents has not been evaluated. Some authorities recommend that the concomitant use of ritlecitinib with other Janus Kinus (JAK) inhibitors, biologic immunomodulators, cyclosporine, or other potent immunosuppressants should be avoided (US). Patients receiving ritlecitinib should be closely monitored for the development of signs and symptoms of infection during and after treatment, including the possible development of tuberculosis in patients who tested negative for latent tuberculosis infection prior to initiating therapy. If a serious infection develops, ritlecitinib therapy should be interrupted until the infection is controlled.

Drug and food interactions

Moderate

thalidomide food

Applies to: thalidomide

GENERALLY AVOID: Alcohol may potentiate some of the pharmacologic effects of CNS-active agents. Use in combination may result in additive central nervous system depression and/or impairment of judgment, thinking, and psychomotor skills.

MANAGEMENT: Patients receiving CNS-active agents should be warned of this interaction and advised to avoid or limit consumption of alcohol. Ambulatory patients should be counseled to avoid hazardous activities requiring complete mental alertness and motor coordination until they know how these agents affect them, and to notify their physician if they experience excessive or prolonged CNS effects that interfere with their normal activities.

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.
