Interactions between your drugs

Major

cloZAPine cladribine

Applies to: FazaClo (clozapine) and Cladribine Novaplus (cladribine)

GENERALLY AVOID: The use of cladribine with other immunosuppressive or myelosuppressive agents may increase the risk of infections. Cladribine alone may cause severe and prolonged myelosuppression, lymphopenia, and opportunistic infections. The risk may theoretically increase when coadministered with other immunosuppressive therapy. Agents that may be significantly myelo- or immunosuppressive include antineoplastic agents, radiation, zidovudine, linezolid, some antirheumatic agents, high dosages of corticosteroids or adrenocorticotropic agents (greater than 10 mg/day to 1 mg/kg/day, whichever is less, of prednisone or equivalent for more than 2 weeks), and long-term topical or inhaled corticosteroids.

MANAGEMENT: Concomitant use of oral cladribine with immunosuppressive or myelosuppressive agents should be avoided if possible. Acute short-term therapy with corticosteroids can be administered. Caution is advised if IV cladribine must be used in patients who have recently received or are receiving treatment with other immunosuppressive or myelosuppressive drugs, and vice versa. Close clinical and laboratory monitoring for the development of severe hematologic adverse effects is recommended both during and after discontinuation of therapy. In patients who have previously been treated with immunomodulatory or immunosuppressive drugs, consider potential additive effect, mode of action, and duration of effect of the other drugs prior to initiation of cladribine. Patients should be advised to contact their physician if they develop signs and symptoms of infection such as fever, chills, diarrhea, sore throat, muscle aches, shortness of breath, blood in phlegm, weight loss, red or inflamed skin, body sores, and pain or burning during urination.

Drug and food interactions

Moderate

cloZAPine food

Applies to: FazaClo (clozapine)

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.

Moderate

cladribine food

Applies to: Cladribine Novaplus (cladribine)

ADJUST DOSING INTERVAL: Oral cladribine may increase the bioavailability of other drugs, which may increase the risk or severity of adverse reactions. Cladribine tablets may contain hydroxypropyl betadex, which could form a complex with the active ingredients of other drugs, especially agents with low solubility. The clinical relevance of this interaction remains unknown.

MANAGEMENT: Administration of oral cladribine should be separated from any other oral drug by at least 3 hours.

Minor

cloZAPine food

Applies to: FazaClo (clozapine)

Caffeine may increase clozapine serum concentrations and exacerbate psychotic symptoms. The mechanism is unknown but may be related to competition for the same metabolic pathway. No specific intervention is necessary; however, if an interaction is suspected it is recommended that caffeine intake be avoided.

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.
