Indications & Clinical Uses

Trimethoprim is an antibacterial agent used primarily in the urinary tract infection pathway.

  • Uncomplicated urinary tract infection: eradicates susceptible bacteria, relieving symptoms and preventing progression.
  • Acute pyelonephritis: contributes to bacterial clearance in kidney infection when combined with appropriate therapy.
  • Recurrent urinary tract infection prophylaxis: reduces incidence of repeat infections during preventive treatment.
  • Travelers' diarrhea (susceptible strains): helps clear infection caused by enteric bacteria.

How It Works

  • Trimethoprim selectively inhibits bacterial dihydrofolate reductase, an enzyme required for the reduction of dihydrofolic acid to tetrahydrofolic acid. By blocking this step, the drug impairs synthesis of nucleic acids and proteins, halting bacterial cell replication. The inhibition is reversible and primarily affects Gram‑negative and some Gram‑positive organisms that rely on folate metabolism, leading to a bacteriostatic effect at therapeutic concentrations.

Side Effects

Trimethoprim may cause a range of adverse reactions, varying from mild to serious.

Common Side Effects

  • Nausea: mild stomach upset or queasiness.
  • Vomiting: occasional expulsion of stomach contents.
  • Diarrhea: loose stools, often transient.
  • Skin rash: mild erythematous eruption.
  • Elevated serum creatinine: reversible increase in kidney function markers.
  • Headache: mild to moderate head discomfort.

Serious or Rare Side Effects

  • Severe allergic reaction: anaphylaxis with airway compromise.
  • Blood dyscrasias: agranulocytosis, aplastic anemia, or leukopenia.
  • Hepatotoxicity: marked elevation of liver enzymes.
  • Stevens‑Johnson syndrome: severe mucocutaneous blistering.
  • Renal toxicity: acute interstitial nephritis.
  • Hemolytic anemia in G6PD deficiency: rapid destruction of red blood cells.

Precautions & Warnings

When prescribing trimethoprim, clinicians should consider several precautionary measures to ensure safe use.

  • Renal function: adjust use in patients with impaired kidney function.
  • Hepatic impairment: monitor liver enzymes in patients with liver disease.
  • Drug hypersensitivity: avoid in individuals with known allergy to trimethoprim or sulfonamides.
  • Pregnancy: assess risk‑benefit as safety data are limited.
  • Concomitant folate antagonists: avoid simultaneous use with methotrexate or pyrimethamine.
  • Store at ambient temperature: keep below 25 °C, in original container, protect from moisture and light.

Avoid Interactions

Trimethoprim can interact with several medicines, altering efficacy or increasing toxicity.

Major Interactions (Avoid)

  • Warfarin: increased anticoagulant effect, risk of bleeding.
  • Methotrexate: additive folate antagonism, heightened toxicity.
  • Phenytoin: reduced plasma levels, decreased seizure control.

Moderate Interactions (Monitor Closely)

  • Digoxin: elevated serum concentrations, monitor cardiac status.
  • Oral contraceptives: decreased effectiveness, advise backup contraception.
  • Rifampin: induces metabolism, may lower trimethoprim levels.
  • NSAIDs: potential for renal impairment, monitor kidney function.

Frequently Asked Questions

Infectotrimet 100 Saft is an oral solution containing trimethoprim, an antibacterial agent indicated for the treatment of uncomplicated urinary tract infections caused by susceptible bacteria. It may also be employed in the management of acute pyelonephritis and for prophylaxis of recurrent urinary tract infections, as prescribed by a qualified healthcare professional.

Trimethoprim exerts its antibacterial effect by selectively inhibiting the bacterial enzyme dihydrofolate reductase. This enzyme is essential for converting dihydrofolic acid to tetrahydrofolic acid, a key step in folic‑acid synthesis required for DNA, RNA and protein production. By blocking this pathway, the drug halts bacterial replication, producing a bacteriostatic effect at therapeutic concentrations.

The dosage of Infectotrimet 100 Saft is determined by the prescribing clinician based on the patient’s age, weight, renal function and the severity of the infection. Healthcare professionals calculate the appropriate amount and frequency according to current clinical guidelines and the product’s labeling. Patients should follow the exact regimen provided by their prescriber and not adjust the dose on their own.

Safety data for trimethoprim in pregnancy are limited, and the drug is generally avoided during the first trimester unless the benefits outweigh potential risks. It may interfere with folate metabolism, which is critical for fetal development. During breastfeeding, trimethoprim is excreted in small amounts in milk; caution is advised, and a healthcare provider should evaluate the risk‑benefit ratio before use.

To place an order, visit the product page on gnhindia.com, submit an enquiry with the required quantity, and provide institutional or trade credentials. GNH India supplies hospitals, pharmacies and procurement teams across international markets. After verification, the sales team will respond with pricing, availability, shipping details—including any temperature‑controlled requirements—and assist with the necessary import documentation.

The most common alternative for uncomplicated urinary tract infections is sulfamethoxazole‑trimethoprim (co‑trimoxazole). While both contain trimethoprim, co‑trimoxazole adds a sulfonamide that provides synergistic folate pathway inhibition, often resulting in broader spectrum activity. Trimethoprim alone may be preferred when sulfonamide intolerance exists or when local resistance patterns favor its use. Clinical efficacy and safety should be evaluated based on susceptibility data and patient-specific factors.

Infectotrimet 100 Saft should be stored at ambient temperature, preferably below 25 °C (77 °F). Keep the bottle tightly closed in its original packaging to protect it from moisture and direct sunlight. Do not freeze the solution. If the product appears discolored or contains particles, discard it and contact the supplier. Ensure that the container is kept out of reach of children.

The oral solution is taken by mouth using a calibrated measuring device, such as a syringe or dosing cup, to ensure accurate volume. It may be administered with or without food, unless the prescribing information advises otherwise. Patients should swallow the measured dose fully and avoid chewing the liquid. If a dose is missed, take it as soon as remembered unless the next scheduled dose is near, in which case skip the missed dose and continue the regular schedule.

The most serious adverse events include severe allergic reactions like anaphylaxis, blood disorders such as agranulocytosis, aplastic anemia, or leukopenia, and hepatic toxicity manifested by marked enzyme elevations. Renal complications such as acute interstitial nephritis and hemolytic anemia in patients with glucose‑6‑phosphate dehydrogenase deficiency can also occur. Prompt medical attention is required if symptoms such as rash, fever, jaundice, dark urine, or unexplained fatigue develop during therapy.

Individuals with a known hypersensitivity to trimethoprim, sulfonamides, or any component of the formulation should avoid the product. Patients with severe renal or hepatic impairment may require alternative therapy or dose adjustment. Those with a history of blood dyscrasias, G6PD deficiency, or who are taking interacting medications such as warfarin, methotrexate, or phenytoin should be evaluated by a healthcare professional before initiating treatment.
