The result is a reduction in the amount of potassium excreted in the urine and an accumulation of serum potassium. In a nested, case-control study of patients older than 66 years who were taking angiotensin converting enzyme inhibitors ACEIs or angiotensin receptor blockers ARBs , the risk of hospital admission for hyperkalemia within 14 days of taking TMP, amoxicillin, ciprofloxacin, norfloxacin, or nitrofurantoin was compared.
Patients taking TMP—sulfamethoxazole had nearly a 7-fold increase in hospitalizations for hyperkalemia compared with patients taking amoxicillin. The use of double-strength TMP mg was associated with a higher risk of hyperkalemia than the single-strength formulation. These drugs may interact with TMP and increase the risk of patients developing hyperkalemia. It is known that combinations of potassium- sparing diuretics and ACEIs eg, enalapril, benazepril, fosinopril, lisinopril or ARBs eg, candesartan, losartan, valsartan can also produce hyperkalemia.
Other risk factors for the development of hyperkalemia include renal dysfunction, diabetes, advanced age, and the use of salt substitutes containing potassium chloride or nonsteroidal anti-inflammatory drugs. Some patients may have several of these risk factors and take multiple interacting drugs. If this patient develops a urinary tract infection, TMP—sulfamethoxazole may be initiated.
The additive effects of these hyperkalemia risk factors may be enough to produce symptomatic hyperkalemia. The selection of an alternate antibiotic or the lowest effective dose of TMP should be considered in this case.
Muscle weakness or bradycardia may be early signs of hyperkalemia, but monitoring the serum potassium concentration is the preferred approach to prevent serious cardiac events. When I looked at the bottle I was very surprised to see that it was Bactrim, which I knew was a sulfur based drug. I asked the pharmacist is this safe for persons with chronic kidney failure and he told me to call my nephrologist before I take it to confirm. It is too late now to call, so I am writing to ask what information is available regarding this question or does anyone know?
Isn't there a more sensible antibiotic to take for cellulitis or to treat this type of infection, it has to be sulfur based? I thank those who answer, in advance. July 16, at pm Trimethoprim, Triamterene, Amiloride, and Pentamidine have the same effect over ENaC, and therefore can cause hyperkalemia Anonymous March 24, at am I'm a practicing nephrologist.
Just saw a patient 2 days ago, stage 4 CKD, Cr 2. Podiatrist placed on Bactrim. We need to educate them. Joel Topf December 21, at pm When I was a fellow, I was a subject in a couple of research studies where the subjects took cimetidine while collecting a hour urine in order to allow the urinary creatinine to better reflect glomerular filtration i.
This study has the advantage of a large sample size, and it certainly suggests that these interacting drugs may have a clinically important effect on levothyroxine serum concentrations. Nonetheless, the effect of individual drugs on levothyroxine cannot be determined because so many different drugs were studied and the results were lumped together. Drugs that Impair Levothyroxine Absorption A number of drugs have been shown to impair the absorption of levothyroxine; these drugs include calcium carbonate, aluminum- containing antacids, sucralfate, iron supplements, cholestyramine, sevelamer, and, possibly, ciprofloxacin, raloxifene, and orlistat.
In one study on the effect of long-term calcium carbonate therapy in 20 hypothyroid patients stabilized on levothyroxine, the TSH level increased in 13 patients in 4, above the normal range , was unchanged in 4 patients, and decreased in 3 patients. One factor that probably contributes to the variability of levothyroxine drug—drug interactions is that some individuals are completely dependent on exogenous levothyroxine eg, following total thyroidectomy while others have varying degrees of residual thyroid function.
Those with some thyroid function may also have varying degrees of feedback stimulation of endogenous thyroid release via thyroidreleasing hormone and TSH. Proton pump inhibitors PPIs have also been reported to reduce levothyroxine absorption, presumably, through an increase in gastric pH, thus reducing dissolution of the levothyroxine tablets.
The bulk of evidence suggests that PPIs reduce levothyroxine absorption,,6 although one small study failed to find an interaction between levothyroxine and omeprazole. One study found that replacing levothyroxine tablets with an oral solution improved levothyroxine absorption in the presence of PPIs. It is rarely necessary to avoid binding agents in patients taking levothyroxine, so if the patient needs to receive the binding agent, the following precautions can minimize the risk of an adverse outcome note: the first 2 bullet points do not apply to proton pump inhibitors because they probably do not bind levothyroxine : Administer levothyroxine at least 2 hours before or 4 hours after the binding agent.

The trimethoprim component of Bactrim may cause hyperkalemia when administered to patients with underlying effects of potassium metabolism, with renal insufficiency or when given concomitantly with bactrim known to induce hyperkalemia, sie as angiotensin converting enzyme inhibitors. Bactrim is also contraindicated in patients with marked hepatic damage or with severe renal insufficiency when renal function status cannot be bactrim.
