It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

Food/lifestyle interactions

No alcohol/food interactions were found. However, this does not necessarily mean no interactions exist. Always consult your healthcare provider.

Disease interactions

18 potential interactions Applies to: 15 conditions, including High Cholesterol, Urinary Tract Infection, Bladder Infection, Fever, and Heart Disease.

Bladder Infection

Major:

cyclophosphamide

cycloPHOSphamide has a major potential interaction with Bladder Infection.

The use of cyclophosphamide is contraindicated in patients with urinary outflow obstruction. Urinary tract obstruction should be excluded or corrected before treatment because cyclophosphamide can cause urotoxicity, which may be fatal.

Bleeding Disorder

Major:

cyclophosphamide

cycloPHOSphamide has a major potential interaction with Bleeding Disorder.

Cyclophosphamide should not be administered to patients with neutrophil counts of 1,500/mm3 or less and platelet counts below 50,000/mm3. Cyclophosphamide can cause myelosuppression, bone marrow failure, and severe immunosuppression; complete blood counts should be monitored during treatment.

Bone Marrow Depression/Low Blood Counts

Major:

cyclophosphamide

cycloPHOSphamide has a major potential interaction with Bone Marrow Depression/Low Blood Counts.

Cyclophosphamide should not be administered to patients with neutrophil counts of 1,500/mm3 or less and platelet counts below 50,000/mm3. Cyclophosphamide can cause myelosuppression, bone marrow failure, and severe immunosuppression; complete blood counts should be monitored during treatment.

Fever

Moderate:

cyclophosphamide

cycloPHOSphamide has a moderate potential interaction with Fever.

Cyclophosphamide treatment may not be indicated, or may require interruption or dose reduction, in patients with a serious infection. Cyclophosphamide can cause severe immunosuppression and reactivate latent infections; it should be used with caution, if at all, in patients with active urinary tract infections.

Heart Disease

Moderate:

cyclophosphamide

cycloPHOSphamide has a moderate potential interaction with Heart Disease.

Cyclophosphamide can cause myocarditis, myopericarditis, pericardial effusion, arrhythmias, and congestive heart failure, which may be fatal. Particular caution is necessary in patients with pre-existing cardiac disease; monitor these patients for cardiotoxicity.

High Cholesterol

Moderate:

rilonacept

Rilonacept has a moderate potential interaction with High Cholesterol.

Patients treated with rilonacept experienced increases in their mean total cholesterol, HDL cholesterol, LDL cholesterol, and triglycerides. The mean increases from baseline for total cholesterol, HDL cholesterol, LDL cholesterol, and triglycerides were 19 mg/dL, 2 mg/dL, 10 mg/dL, and 57 mg/dL respectively after 6 weeks of open-label therapy. Physicians should monitor the lipid profiles of their patients especially those with hyperlipidemias, and consider lipid-lowering therapies as needed based upon cardiovascular risk factors and current guidelines.

History, Radiation Therapy

Moderate:

cyclophosphamide

cycloPHOSphamide has a moderate potential interaction with History, Radiation Therapy.

Previous radiation treatment to the cardiac region may increase the risk of cyclophosphamide cardiotoxicity, and previous abdominal radiation is a risk factor for cyclophosphamide-associated veno-occlusive liver disease. Patients with risk factors for cardiotoxicity should be monitored during treatment.

Infection

Moderate:

cyclophosphamide

cycloPHOSphamide has a moderate potential interaction with Infection.

Cyclophosphamide treatment may not be indicated, or may require interruption or dose reduction, in patients with a serious infection. Cyclophosphamide can cause severe immunosuppression and reactivate latent infections; it should be used with caution, if at all, in patients with active urinary tract infections.

Moderate:

rilonacept

Rilonacept has a moderate potential interaction with Infection.

Interleukin-1 (IL-1) blockade may interfere with the immune response to infections. Treatment with other medication as rilonacept, that work through inhibition of IL-1 has been associated with an increased risk of serious infections, and serious infections have been reported in patients taking rilonacept compared with placebo. Rilonacept should be discontinued if a patient develops a serious infection. Treatment with rilonacept should not be initiated in patients with an active or chronic infection. Additionally, latent tuberculosis can be reactivated and should be treated before initiating therapy with rilonacept.

Liver Disease

Moderate:

cyclophosphamide

cycloPHOSphamide has a moderate potential interaction with Liver Disease.

Pre-existing disturbances of hepatic function are a risk factor for cyclophosphamide-associated veno-occlusive liver disease, which can be fatal. Severe hepatic impairment may reduce conversion of cyclophosphamide to its active metabolite, potentially reducing efficacy.

Moderate:

rilonacept

Rilonacept has a moderate potential interaction with Liver Disease.

No formal studies have been conducted to examine the pharmacokinetics of rilonacept administered subcutaneously in patients with hepatic impairment. Caution is advised if used on these patients.

Pulmonary Impairment

Moderate:

cyclophosphamide

cycloPHOSphamide has a moderate potential interaction with Pulmonary Impairment.

Pneumonitis, pulmonary fibrosis, pulmonary veno-occlusive disease and other forms of pulmonary toxicity leading to respiratory failure have been reported during and following treatment with cyclophosphamide. Pneumonitis may develop years after treatment with cyclophosphamide. Patients should be monitored for signs and symptoms of pulmonary toxicity. Caution is advised in patients with preexisting pulmonary impairment.

Renal Dysfunction

Moderate:

cyclophosphamide

cycloPHOSphamide has a moderate potential interaction with Renal Dysfunction.

In patients with severe renal impairment, decreased renal excretion may result in increased plasma levels of cyclophosphamide and its metabolites, which may result in increased toxicity. Monitor patients with severe renal impairment (CrCl =10 mL/min to 24 mL/min) for signs and symptoms of toxicity. Therapy with cyclophosphamide should be administered cautiously in patients with a history of or predisposition to renal dysfunction. Clinical monitoring of renal function is recommended.

Moderate:

rilonacept

Rilonacept has a moderate potential interaction with Renal Dysfunction.

No formal studies have been conducted to examine the pharmacokinetics of rilonacept administered subcutaneously in patients with renal impairment. Caution is advised if used on these patients.

Tuberculosis, Latent

Moderate:

rilonacept

Rilonacept has a moderate potential interaction with Tuberculosis, Latent.

Interleukin-1 (IL-1) blockade may interfere with the immune response to infections. Treatment with other medication as rilonacept, that work through inhibition of IL-1 has been associated with an increased risk of serious infections, and serious infections have been reported in patients taking rilonacept compared with placebo. Rilonacept should be discontinued if a patient develops a serious infection. Treatment with rilonacept should not be initiated in patients with an active or chronic infection. Additionally, latent tuberculosis can be reactivated and should be treated before initiating therapy with rilonacept.

Urinary Tract Infection

Major:

cyclophosphamide

cycloPHOSphamide has a major potential interaction with Urinary Tract Infection.

The use of cyclophosphamide is contraindicated in patients with urinary outflow obstruction. Urinary tract obstruction should be excluded or corrected before treatment because cyclophosphamide can cause urotoxicity, which may be fatal.

Urinary Tract Obstruction

Major:

cyclophosphamide

cycloPHOSphamide has a major potential interaction with Urinary Tract Obstruction.

The use of cyclophosphamide is contraindicated in patients with urinary outflow obstruction. Urinary tract obstruction should be excluded or corrected before treatment because cyclophosphamide can cause urotoxicity, which may be fatal.

Vaccination

Major:

rilonacept

Rilonacept has a major potential interaction with Vaccination.

Live vaccines should not be given concurrently with rilonacept. Rilonacept may interfere with normal immune response to new antigens; therefore, vaccinations may not be effective in patients receiving rilonacept. No data are available on the effectiveness of vaccination with inactivated (killed) antigens in patients receiving rilonacept. Because IL-1 blockade may interfere with immune response to infections, it is recommended that prior to initiation of therapy with rilonacept adult and pediatric patients receive all recommended vaccinations, as appropriate, including pneumococcal vaccine and inactivated influenza vaccine.
