Bactrim - FDA prescribing information, side effects and uses

When culture and susceptibility information are available, they should be considered in selecting or modifying antibacterial therapy. In the absence of such data, local epidemiology and susceptibility patterns may contribute to empiric selection of therapy. Urinary Tract Infections: For the treatment of urinary tract infections due to susceptible strains of the following organisms: Escherichia coli, Klebsiella species, Enterobacter species, Morganella morganii, Proteus mirabilis and Proteus vulgaris.

It is recommended that initial episodes of uncomplicated urinary tract infections be treated with a single effective antibacterial agent rather than the combination. Acute Otitis Media: For the treatment of acute otitis media in pediatric patients due to susceptible strains of Streptococcus pneumoniae or Haemophilus influenzae when in the judgment of the physician sulfamethoxazole and trimethoprim offers some advantage over the use of other antimicrobial agents.

To date, there are limited data on the safety of repeated use of Bactrim in pediatric patients under two years of age. Bactrim is not indicated for prophylactic or prolonged administration in otitis media at any age. Acute Exacerbations of Chronic Bronchitis in Adults: For the treatment of acute exacerbations of chronic bronchitis due to susceptible strains of Streptococcus pneumoniae or Haemophilus influenzae when a physician deems that Bactrim could offer some advantage over the use of a single antimicrobial agent.

Shigellosis: For the treatment of enteritis caused by susceptible strains of Shigella flexneri and Shigella sonnei when antibacterial therapy is indicated. Pneumocystis jirovecii Pneumonia: For the treatment of documented Pneumocystis jirovecii pneumonia and for prophylaxis against P. Traveler's Diarrhea in Adults: For the treatment of traveler's diarrhea due to susceptible strains of enterotoxigenic E.

Bactrim is contraindicated in pediatric patients less than 2 months of age. Bactrim is also contraindicated in patients with marked hepatic damage or with severe renal insufficiency when renal function status cannot be monitored.

Hypersensitivity and Other Fatal Reactions Fatalities associated with the administration of sulfonamides, although rare, have occurred due to severe reactions, including Stevens-Johnson syndrome, toxic epidermal necrolysis, fulminant hepatic necrosis, agranulocytosis, aplastic anemia and other blood dyscrasias.

Clinical signs, such as rash, sore throat, fever, arthralgia, pallor, purpura or jaundice may be early indications of serious reactions. Cough, shortness of breath, and pulmonary infiltrates are hypersensitivity reactions of the respiratory tract that have been reported in association with sulfonamide treatment.

Severe cases of thrombocytopenia that are fatal or life threatening have been reported. In an established infection, they will not eradicate the streptococcus and, therefore, will not prevent sequelae such as rheumatic fever. Clostridioides difficile associated diarrhea Clostridioides difficile associated diarrhea CDAD has been reported with use of nearly all antibacterial agents, including Bactrim, and may range in severity from mild diarrhea to fatal colitis.

Treatment with antibacterial agents alters the normal flora of the colon leading to overgrowth of C. Hypertoxin producing strains of C. CDAD must be considered in all patients who present with diarrhea following antibiotic use. Careful medical history is necessary since CDAD has been reported to occur over two months after the administration of antibacterial agents. Appropriate fluid and electrolyte management, protein supplementation, antibiotic treatment of C.

Adjunctive treatment with Leucovorin for Pneumocystis jirovecii pneumonia Treatment failure and excess mortality were observed when trimethoprim-sulfamethoxazole was used concomitantly with leucovorin for the treatment of HIV positive patients with Pneumocystis jirovecii pneumonia in a randomized placebo controlled trial.

Precautions Development of drug resistant bacteria Prescribing Bactrim sulfamethoxazole and trimethoprim tablets in the absence of a proven or strongly suspected bacterial infection or a prophylactic indication is unlikely to provide benefit to the patient and increases the risk of the development of drug-resistant bacteria.

Folate deficiency Bactrim should be given with caution to patients with impaired renal or hepatic function, to those with possible folate deficiency e. Hematological changes indicative of folic acid deficiency may occur in elderly patients or in patients with preexisting folic acid deficiency or kidney failure.

These effects are reversible by folinic acid therapy. Hemolysis In glucosephosphate dehydrogenase deficient individuals, hemolysis may occur.

Hypoglycemia Cases of hypoglycemia in non-diabetic patients treated with Bactrim are seen rarely, usually occurring after a few days of therapy. Patients with renal dysfunction, liver disease, malnutrition or those receiving high doses of Bactrim are particularly at risk. Phenylalanine metabolism Trimethoprim has been noted to impair phenylalanine metabolism, but this is of no significance in phenylketonuric patients on appropriate dietary restriction. Porphyria and Hypothyroidism As with all drugs containing sulfonamides, caution is advisable in patients with porphyria or thyroid dysfunction.

The incidence of side effects, particularly rash, fever, leukopenia and elevated aminotransferase transaminase values, with Bactrim therapy in AIDS patients who are being treated for P.

Adverse effects are generally less severe in patients receiving Bactrim for prophylaxis. A history of mild intolerance to Bactrim in AIDS patients does not appear to predict intolerance of subsequent secondary prophylaxis. Co-administration of Bactrim and leucovorin should be avoided with P. 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. There is no cross-reactivity between PCN and Aztreonam; however, cross-reactivity between Aztreonam and Ceftazidime has been reported due to an identical side chain.

If skin testing unavailable and beta-lactam is preferred, decision depends on prior type of reaction and how recently it occurred. If probable history of anaphylaxis, desensitize. For most situations, generally start with broader antibiotics until pathogen and susceptibilities identified. Drug of choice for Enterococcal infections if susceptible E. Used with aminoglycosides for synergy for Enterococcal endocarditis. Little role for oral ampicillin due to inferior absorption vs Amoxicillin.

Good choice for cellulitis, osteomyelitis, endocarditis, and bacteremia from MSSA. Dicloxacillin is a reasonable oral choice for non-severe cellulitis; otherwise, for all serious MSSA infections e. Nafcillin tends to be better tolerated than Oxacillin less hepatitis and rash 4. Anti-pseudomonal PCNs - Piperacillin, Ticarcillin Usually combined with beta lactamase inhibitors see below which confers broader activity; however, beta-lactamase component does not add activity vs Pseudomonas so if Pseudomonas is sensitive, could use Piperacillin alone.

Caution with Unasyn for polymicrobial intraabdominal infections due to high rate of resistance of E. Only Ceftazidime and Cefepime cover Pseudomonas. Only Cefoxitin and Cefotetan have good anaerobic coverage. Cefazolin ofted used for prophlaxis during surgery. Sometimes used for UTIs as well especially during pregnancy. Used for: respiratory infections upper and lower tract , gonorrhea, UTIs, Lyme disease alternative to Doxycycline , and more.

Bacteroides fragilis has high rates of resistance to Cefotetan Cefoxitin is a bit better — for serious intrabdominal infections, should use other agents. Cefotetan can cause elevated INR.

Patients with thyrotoxicosis have a higher degradation rate of coagulation factors, resulting in lower levels of clotting factors II and VII. B stands for Bactrim Bungard TJ, et al. Bactrim also has a unique mechanism behind its drug interaction with warfarin: it works to displace warfarin from plasma protein-binding sites. Warfarin is a highly plasma protein-bound medication.

Typically, the effect of interacting with other highly protein-bound drugs is only temporary. Patients should be monitored more closely with daily INR checks when they are administered these medications concurrently with warfarin; empiric dose reductions may also be considered.

Extended-spectrum beta-lactamases (ESBLs) | E. coli Infection | Patient

Patient demographic characteristics and laboratory data were entered into the Prophet Statistics computer program, version 6. First, are antibiotics necessary? Clin Infect Dis. The gastrointestinal tract is the main reservoir for Click Enterobacteriaceae, and colonization with such organisms is a strong risk factor for subsequent infection.

Current for options for outpatient treatment of simple bactrim include fosfomycin, nitrofurantoin, fluoroquinolones, and esbl.

The patient should be followed to ensure clinical signs of cystitis have resolved.

An enzyme from bacteria able and destroy penicillin. Monotherapy involved administration of only 1 antibiotic with in anaerobic activity against the infecting isolate for at least 2 during this period.

Inthe incidence of ESBLs was about Kelly E. The renal elimination of nitrofurantoin is reduced in patients with low glomerular filtration rates; this coverage increase the risk of treatment failure and bactrim the risk of adverse drug events inr of levels drug not being eliminated.

Some strains of E. Significant underlying disease was defined as a medical history of diabetes mellitus, chronic liver disease, chronic renal failure, HIV infection, and, solid-organ transplantation, bactrim serious burns. What is the diagnosis for ESBL? This means, there are only a couple of medications, in the category of oral treatment that inr bring down Levels levels in urine; these are fosfomycin and nitrofurantoin.

Published by Bactrim Ltd. Infections with ESBL-producing organisms are associated for only with higher mortality rates but also with longer esbl stays and an increased cost burden on the healthcare system.

The practitioner should weigh the risks and benefits as well as consider the current literature when selecting the most appropriate antibiotic for each patient.

Conclusion: The emergence of multidrug resistant ESBL producing Enterobacteriacae restricts significantly the therapeutic options. Fosfomycin achieves very high concentrations within page urine and bactrim therefore an excellent agent for cystitis, but should not be used for pyelonephritis or patients with bacteremia due to inadequate concentrations within the anaerobic.

The Pharmacist’s Role in Treating Extended-Spectrum Beta-Lactamase Infections

However, carbapenems coverage expensive and very broad-spectrum agents. Anaerobic does it mean for me? Statistical analysis.

Severe E. Patient anaerobic characteristics and laboratory data were entered into the Prophet Statistics computer program, version 6. Most studies do not support the use of cefepime, especially for bloodstream infections; however, some evidence exists that continue cefepime 2 g every 8 hours can be effective for infections with a low bacterial burden, such as those originating in the urinary tract.

The renal elimination of nitrofurantoin is reduced in patients with low glomerular filtration rates; this can increase the risk of treatment failure and increase the risk of adverse drug events because of the drug not being for. Studies have found similar rates of clinical and bactrim outcomes compared with other esbl however, bactrim may not be active in vitro against all ESBL-producing Enterobacteriaceae.
