Disease interactions
13 potential interactions Applies to: 12 conditions, including Heart Failure, Diarrhea, Anemia, Inflammatory Bowel Disease, and Peptic Ulcer.
Alcoholism
Major:
methotrexate
Methotrexate has a major potential interaction with Alcoholism.
The use of methotrexate is contraindicated as treatment for psoriasis or rheumatoid arthritis in patients with alcoholism, alcoholic liver disease or other chronic liver diseases. Methotrexate causes hepatotoxicity, fibrosis and cirrhosis, usually after long-term therapy. Fibrosis and cirrhosis may not be preceded by symptoms or abnormal liver function tests. If methotrexate is used, patients should be instructed to immediately report any signs or symptoms suggestive of hepatic dysfunction such as jaundice, dark urine, right upper quadrant pain, or anorexia. Persistent liver function test abnormalities and/or depression of serum albumin may require evaluation, including a liver biopsy.
Anemia
Major:
methotrexate
Methotrexate has a major potential interaction with Anemia.
Methotrexate can induce myelosuppression causing leukopenia, thrombocytopenia, neutropenia, pancytopenia and anemia. Therapy with methotrexate is contraindicated as treatment of psoriasis in patients with bone marrow suppression or preexisting blood dyscrasias. Methotrexate should be discontinued immediately in patients with psoriasis or rheumatoid arthritis if there is a significant fall in blood cell counts. If need outweighs risk, therapy with methotrexate should be administered cautiously in patients with malignancy and hematopoietic impairment. Additionally, methotrexate should be used with extreme caution in patients with active infection, and it is usually contraindicated in patients with overt or laboratory evidence of immunodeficiency syndromes. Patients should be instructed to immediately report any signs or symptoms suggesting bone marrow suppression or infection such as fever, sore throat, or bleeding. Clinical monitoring of hematopoietic function is recommended.
Bone Marrow Depression/Low Blood Counts
Major:
methotrexate
Methotrexate has a major potential interaction with Bone Marrow Depression/Low Blood Counts.
Methotrexate can induce myelosuppression causing leukopenia, thrombocytopenia, neutropenia, pancytopenia and anemia. Therapy with methotrexate is contraindicated as treatment of psoriasis in patients with bone marrow suppression or preexisting blood dyscrasias. Methotrexate should be discontinued immediately in patients with psoriasis or rheumatoid arthritis if there is a significant fall in blood cell counts. If need outweighs risk, therapy with methotrexate should be administered cautiously in patients with malignancy and hematopoietic impairment. Additionally, methotrexate should be used with extreme caution in patients with active infection, and it is usually contraindicated in patients with overt or laboratory evidence of immunodeficiency syndromes. Patients should be instructed to immediately report any signs or symptoms suggesting bone marrow suppression or infection such as fever, sore throat, or bleeding. Clinical monitoring of hematopoietic function is recommended.
Diarrhea
Major:
methotrexate
Methotrexate has a major potential interaction with Diarrhea.
Methotrexate induces stomatitis within the oral mucosa and gastrointestinal tract. Therapy with methotrexate should be administered with extreme caution in patients with peptic ulcer disease or ulcerative colitis. If vomiting, diarrhea or ulcerative stomatitis occur, treatment should be discontinued until recovery to avoid the risk of hemorraghic enteritis or intestinal perforation which could be fatal.
G-6-PD Deficiency
Major:
Krystexxa
The pegloticase in Krystexxa has a major potential interaction with G-6-PD Deficiency.
The antihyperuricemic agents pegloticase and rasburicase are contraindicated in patients deficient in glucose-6-phosphate-dehydrogenase (G6PD), as these have shown to cause severe hemolytic reactions and methemoglobinemia. Patients at high risk of G6PD deficiency such as patients of African, Mediterranean or Southern Asian ancestry, should be screened prior to starting treatment. Treatment with any of these drugs should be discontinued immediately and permanently in any patient developing hemolysis or methemoglobinemia.
Heart Failure
Moderate:
Krystexxa
The pegloticase in Krystexxa has a moderate potential interaction with Heart Failure.
Pegloticase has not been formally studied in patients with congestive heart failure, and some patients in clinical trials have experienced exacerbation. Caution should be exercised when using pegloticase in these patients and close monitoring following the infusion is recommended.
Infection
Major:
methotrexate
Methotrexate has a major potential interaction with Infection.
Because of their cytotoxic effects on rapidly proliferating tissues, antineoplastic agents frequently can, to varying extent, induce myelosuppression. The use of these drugs may be contraindicated in patients with known infectious diseases. All patients should be instructed to immediately report any signs or symptoms suggesting infection such as fever, sore throat, or local infection during antineoplastic therapy. Close clinical monitoring of hematopoietic function is recommended.
Major:
methotrexate
Methotrexate has a major potential interaction with Infection.
Methotrexate can induce myelosuppression causing leukopenia, thrombocytopenia, neutropenia, pancytopenia and anemia. Therapy with methotrexate is contraindicated as treatment of psoriasis in patients with bone marrow suppression or preexisting blood dyscrasias. Methotrexate should be discontinued immediately in patients with psoriasis or rheumatoid arthritis if there is a significant fall in blood cell counts. If need outweighs risk, therapy with methotrexate should be administered cautiously in patients with malignancy and hematopoietic impairment. Additionally, methotrexate should be used with extreme caution in patients with active infection, and it is usually contraindicated in patients with overt or laboratory evidence of immunodeficiency syndromes. Patients should be instructed to immediately report any signs or symptoms suggesting bone marrow suppression or infection such as fever, sore throat, or bleeding. Clinical monitoring of hematopoietic function is recommended.
Inflammatory Bowel Disease
Major:
methotrexate
Methotrexate has a major potential interaction with Inflammatory Bowel Disease.
Methotrexate induces stomatitis within the oral mucosa and gastrointestinal tract. Therapy with methotrexate should be administered with extreme caution in patients with peptic ulcer disease or ulcerative colitis. If vomiting, diarrhea or ulcerative stomatitis occur, treatment should be discontinued until recovery to avoid the risk of hemorraghic enteritis or intestinal perforation which could be fatal.
Liver Disease
Major:
methotrexate
Methotrexate has a major potential interaction with Liver Disease.
The use of methotrexate is contraindicated as treatment for psoriasis or rheumatoid arthritis in patients with alcoholism, alcoholic liver disease or other chronic liver diseases. Methotrexate causes hepatotoxicity, fibrosis and cirrhosis, usually after long-term therapy. Fibrosis and cirrhosis may not be preceded by symptoms or abnormal liver function tests. If methotrexate is used, patients should be instructed to immediately report any signs or symptoms suggestive of hepatic dysfunction such as jaundice, dark urine, right upper quadrant pain, or anorexia. Persistent liver function test abnormalities and/or depression of serum albumin may require evaluation, including a liver biopsy.
Peptic Ulcer
Major:
methotrexate
Methotrexate has a major potential interaction with Peptic Ulcer.
Methotrexate induces stomatitis within the oral mucosa and gastrointestinal tract. Therapy with methotrexate should be administered with extreme caution in patients with peptic ulcer disease or ulcerative colitis. If vomiting, diarrhea or ulcerative stomatitis occur, treatment should be discontinued until recovery to avoid the risk of hemorraghic enteritis or intestinal perforation which could be fatal.
Pleural Effusion
Major:
methotrexate
Methotrexate has a major potential interaction with Pleural Effusion.
Methotrexate is primarily eliminated by the kidney via glomerular filtration and active secretion. Clearance rates for methotrexate vary and at higher doses are generally decreased due to saturation of renal tubular reabsorption. Renal impairment or third space effusion (ascites, pleural effusions), decrease elimination and increase methotrexate serum concentrations. Therapy with methotrexate should be administered cautiously and at reduced dosages in patients with compromised renal function. Administration of leucovorin reduces toxicity from high dose methotrexate regimens or delayed elimination. Clinical monitoring of renal function is recommended.
Renal Dysfunction
Major:
methotrexate
Methotrexate has a major potential interaction with Renal Dysfunction.
Methotrexate is primarily eliminated by the kidney via glomerular filtration and active secretion. Clearance rates for methotrexate vary and at higher doses are generally decreased due to saturation of renal tubular reabsorption.
