Bactrim ds 800mg
Increased digoxin blood levels can occur with concomitant Bactrim therapy, especially in elderly patients. Serum digoxin levels should be monitored. Increased sulfamethoxazole blood levels may occur in patients who are also receiving indomethacin. Occasional reports suggest that patients receiving pyrimethamine as malaria prophylaxis in doses exceeding 25 mg weekly may develop megaloblastic anemia if Bactrim is prescribed. The efficacy of tricyclic antidepressants can decrease when coadministered with Bactrim.
Bactrim potentiates the effect of oral hypoglycemics that are metabolized by CYP2C8 e. Additional monitoring of blood glucose may be warranted. Cases of interactions with other OCT2 substrates, memantine and metformin, have also been reported. Bactrim, specifically the trimethoprim component, can interfere with a serum methotrexate assay as determined by the competitive binding protein technique CBPA when a bacterial dihydrofolate reductase is used as the binding protein.
No interference occurs, however, if methotrexate is measured by a radioimmunoassay RIA. Carcinogenesis, Mutagenesis, Impairment of Fertility: In vitro reverse mutation bacterial tests according to the standard protocol have not been performed with sulfamethoxazole and trimethoprim in combination. Observations of leukocytes obtained from patients treated with sulfamethoxazole and trimethoprim revealed no chromosomal abnormalities. Sulfamethoxazole alone was positive in an in vitro reverse mutation bacterial assay and in in vitro micronucleus assays using cultured human lymphocytes.
Trimethoprim alone was negative in in vitro reverse mutation bacterial assays and in in vitro chromosomal aberration assays with Chinese Hamster ovary or lung cells with or without S9 activation.
In in vitro Comet, micronucleus and chromosomal damage assays using cultured human lymphocytes, trimethoprim was positive. In mice following oral administration of trimethoprim, no DNA damage in Comet assays of liver, kidney, lung, spleen, or bone marrow was recorded. While there are no large, well-controlled studies on the use of sulfamethoxazole and trimethoprim in pregnant women, Brumfitt and Pursell,10 in a retrospective study, reported the outcome of pregnancies during which the mother received either placebo or sulfamethoxazole and trimethoprim.
The incidence of congenital abnormalities was 4. There were no abnormalities in the 10 children whose mothers received the drug during the first trimester. In a separate survey, Brumfitt and Pursell also found no congenital abnormalities in 35 children whose mothers had received oral sulfamethoxazole and trimethoprim at the time of conception or shortly thereafter.
Because sulfamethoxazole and trimethoprim may interfere with folic acid metabolism, Bactrim should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. These studies, however, were limited by the small number of exposed cases and the lack of adjustment for multiple statistical comparisons and confounders.
These studies are further limited by recall, selection, and information biases, and by limited generalizability of their findings. Lastly, outcome measures varied between studies, limiting cross-study comparisons. These doses are approximately 5 and 6 times the recommended human total daily dose on a body surface area basis.

Major Pimavanserin may cause QT prolongation and should generally be avoided in patients receiving other medications known to prolong the QT interval, such as sulfamethoxazole; trimethoprim. Coadministration may increase the risk for QT prolongation. Severe Pimozide is associated with a well-established risk of QT prolongation and torsade de pointes TdP.
Major Posaconazole and sulfamethoxazole should be coadministered with caution due to an increased potential for sulfamethoxazole-related adverse events.
Posaconazole is a potent inhibitor of CYP3A4, an isoenzyme partially responsible for the metabolism of sulfamethoxazole. These drugs used in combination may result in elevated sulfamethoxazole plasma concentrations, causing an increased risk for sulfamethoxazole-related adverse events.
Potassium Phosphate; Sodium Phosphate: Concomitant administration of drugs that undergo substantial renal clearance, such as sulfamethoxazole; trimethoprim, SMX-TMP, may result in delayed clearance of pralatrexate.
