Together they form a unique fingerprint. Sulfamethoxazole Drug Combination Trimethoprim Medicine & Life Science Trimethoprim (with or without sulfamethoxazole) prescribing is associated with an increased risk of hyperkalaemia, AKI, and death, compared to amoxicillin [16-19]. Amoxicillin accounts for only about 5% of prescribing for UTI in the UK [ 9 ] and thus is a less helpful comparator for clinical decision-making

Use caution in patients with potential for folate deficiency, including malnourished, chronic anticonvulsant therapy, or elderly; folates may be administered concomitantly without interfering with antibacterial action of trimethoprim. Some dosage forms may contain benzyl alcohol and derivatives; avoid in neonate Another drawback of FQ therapy is the subsequent risk of Clostridioides difficile infection, in particular in the elderly. Therefore, alternative drugs to FQs are needed.

It is also strongly anticholinergic, and may cause urine retention, confusion, and sedation. Digoxin is substantially excreted by the kidney. Because elderly patients are more likely to have decreased renal function, there is an increased risk of toxicity at doses exceeding 0.125 mg/day Trimethoprim should be used cautiously in patients with impaired renal function. Use in elderly Care should be exercised in treating elderly because, as a group, they are more susceptible to adverse reactions and more likely to suffer serious effects as a result.
