Careful medical history is necessary since CDAD has been reported to occur over bactrim months after the administration of antibacterial agents. High dosage of trimethoprim, as used in patients with Pneumocystis jiroveci pneumonia, induces a progressive but reversible increase of serum potassium concentrations in a substantial number of patients.

  • DESCRIPTION

Electrolyte Abnormalities High dosage of trimethoprim, as used in patients with P. Even treatment with recommended doses may cause hyperkalemia when trimethoprim is administered to patients with underlying disorders of potassium metabolism, with renal insufficiency, or if drugs known to induce hyperkalemia are given concomitantly.

Close monitoring of serum potassium is warranted in these patients. Severe and symptomatic hyponatremia can occur in patients receiving Bactrim, particularly for the treatment of P. Evaluation for hyponatremia and appropriate correction is necessary in symptomatic patients to prevent life-threatening complications.

During treatment, adequate fluid intake and urinary output should be ensured to prevent crystalluria. Information for Patients: Patients should be counseled that antibacterial drugs including Bactrim sulfamethoxazole and trimethoprim tablets should only be used to treat bacterial infections. They do not treat viral infections e. When Bactrim sulfamethoxazole and trimethoprim tablets are prescribed to treat a bacterial infection, patients should be told that although it is common to feel better early in the course of therapy, the medication should be taken exactly as directed.

Skipping doses or not completing the full course of therapy may 1 decrease the effectiveness of the immediate treatment and 2 increase the likelihood that bacteria will develop resistance and will not be treatable by Bactrim sulfamethoxazole and trimethoprim tablets or other antibacterial drugs in the future. Patients should be instructed to maintain an adequate fluid intake in order to prevent crystalluria and stone formation. Diarrhea is a common problem caused by antibiotics which usually ends when the antibiotic is discontinued.

Sometimes after starting treatment with antibiotics, patients can develop watery and bloody stools with or without stomach cramps and fever even as late as two or more months after having taken the last dose of the antibiotic. If this occurs, patients should contact their physician as soon as possible. Laboratory Tests: Complete blood counts should be done frequently in patients receiving Bactrim; if a significant reduction in the count of any formed blood element is noted, Bactrim should be discontinued.

Urinalyses with careful microscopic examination and renal function tests should be performed during therapy, particularly for those patients with impaired renal function. Sulfamethoxazole is an inhibitor of CYP2C9. In elderly patients concurrently receiving certain diuretics, primarily thiazides, an increased incidence of thrombocytopenia with purpura has been reported. It has been reported that Bactrim may prolong the prothrombin time in patients who are receiving the anticoagulant warfarin a CYP2C9 substrate.

This interaction should be kept in mind when Bactrim is given to patients already on anticoagulant therapy, and the coagulation time should be reassessed. Bactrim may inhibit the hepatic metabolism of phenytoin a CYP2C9 substrate. When administering these drugs concurrently, one should be alert for possible excessive phenytoin effect. Sulfonamides can also displace methotrexate from plasma protein binding sites and can compete with the renal transport of methotrexate, thus increasing free methotrexate concentrations.

There have been reports of marked but reversible nephrotoxicity with coadministration of Bactrim and cyclosporine in renal transplant recipients.

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. No interference occurs, however, if methotrexate is measured by a radioimmunoassay RIA.

Mutagenesis: 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.

Common Bactrim side effects may include: nausea , vomiting, loss of appetite; or skin rash. Increased digoxin blood levels can occur with concomitant sulfamethoxazole and trimethoprim therapy, especially in elderly patients. Serum digoxin levels should be monitored.

Occasional reports suggest that patients receiving pyrimethamine as malaria prophylaxis in doses exceeding 25 mg weekly may develop megaloblastic anemia if sulfamethoxazole and trimethoprim is prescribed. The efficacy of tricyclic antidepressants can decrease when coadministered with sulfamethoxazole and trimethoprim. Like other sulfonamide-containing drugs, sulfamethoxazole and trimethoprim potentiates the effect of oral hypoglycemics. No interference occurs, however, if methotrexate is measured by a radioimmunoassay RIA.

Carcinogenesis, Mutagenesis, Impairment of Fertility Carcinogenesis: Long-term studies in animals to evaluate carcinogenic potential have not been conducted with sulfamethoxazole and trimethoprim.

Mutagenesis: Bacterial mutagenic studies have not been performed with sulfamethoxazole and trimethoprim in combination. Trimethoprim was demonstrated to be nonmutagenic in the Ames assay. No chromosomal damage was observed in human leukocytes cultured in vitro with sulfamethoxazole and trimethoprim alone or in combination; the concentrations used exceeded blood levels of these compounds following therapy with sulfamethoxazole and trimethoprim.

Observations of leukocytes obtained from patients treated with sulfamethoxazole and trimethoprim revealed no chromosomal abnormalities. In some rabbit studies, an overall increase in fetal loss dead and resorbed and malformed conceptuses was associated with doses of trimethoprim 6 times the human therapeutic dose.

While there are no large, well-controlled studies on the use of sulfamethoxazole and trimethoprim in pregnant women, Brumfitt and Pursell,8 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, sulfamethoxazole and trimethoprim should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.

Geriatric Use Clinical studies of sulfamethoxazole and trimethoprim did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. There may be an increased risk of severe adverse reactions in elderly patients, particularly when complicating conditions exist, e. In those concurrently receiving certain diuretics, primarily thiazides, an increased incidence of thrombocytopenia with purpura has been reported.

Hematological changes indicative of folic acid deficiency may occur in elderly patients. The trimethoprim component of sulfamethoxazole and trimethoprim may cause hyperkalemia when administered to patients with underlying disorders of potassium metabolism, with renal insufficiency or when given concomitantly with drugs known to induce hyperkalemia, such as angiotensin converting enzyme inhibitors.

Discontinuation of sulfamethoxazole and trimethoprim treatment is recommended to help lower potassium serum levels. Sulfamethoxazole and trimethoprim oral suspension contains 2.

Pharmacokinetics parameters for sulfamethoxazole were similar for geriatric subjects and younger adult subjects. Adverse Reactions The most common adverse effects are gastrointestinal disturbances nausea, vomiting, anorexia and allergic skin reactions such as rash and urticaria.
