What Is Trimethoprim?

Trimethoprim is an antibiotic medication used to treat a variety of bacterial infections. It’s most commonly used against urinary tract infections, although it can also be used to treat other bacterial infections such as outer ear infections and some types of diarrhea.

Trimethoprim works by stopping the growth of bacteria by inhibiting an enzyme that bacteria need to produce DNA. Which stops the bacteria from multiplying.

It is often combined with other drugs like an antibiotic called sulfamethoxazole. Together, they form the combination drug known as co-trimoxazole (brand names include Bactrim, Septra). This combination helps broaden the spectrum of bacterial targets and can help prevent bacterial resistance.

What Is Trimethoprim Used For?

Trimethoprim is typically prescribed for treating bacterial infections. This antibiotic won’t work on viral infections such as a cold or flu.

Primarily it’s used to treat urinary tract infections (UTIs) that are caused by bacteria but it can also be prescribed for other bacteria.

Common uses:

  • Urinary tract infections
  • Ear infections (Otitis Media)
  • Sinus infections
  • Respiratory tract infections (bronchitis, pneumonia)
  • Gastrointestinal tract infections (traveler’s diarrhea)
  • Skin and soft tissue infections

In some cases, trimethoprim (when combined with sulfamethoxazole) can be used to prevent certain types of pneumocystis pneumonia in people with weakened immune systems (such as people with HIV/AIDS).

What Are the Side Effects of Trimethoprim?

The most common side effects of Trimethoprim include:

  • Nausea
  • Vomiting
  • Diarrhea
  • Skin rash
  • Loss of appetite
  • Changes in taste
  • Sun sensitivity
  • Itchiness
  • Muscle or joint pain

More serious side effects may include:

  • Blood disorders
  • Liver problems
  • Kidney issues
  • Allergic reactions
  • Serious skin reactions
  • Hyperkalemia Kidney

The above list of possible side effects from Trimethoprim is not exhaustive. If you experience any unusual or severe side effects while taking the antibiotic seek immediate medical attention.

Also if you have any concerns about potential interactions with other medications you are taking, contact your doctor for further information.

How to Take Trimethoprim?

When taking Trimethoprim, it is essential to follow precisely the instructions of your doctor. This includes the dosage, how long it needs to be taken, the frequency, and any other instructions.

The dosage is tailored based on individual medical conditions, age, and, in children, weight considerations.

Take the medication as prescribed and do not stop taking it until advised by your doctor even if you feel better or your symptoms disappear. Stopping the antibiotic course early may result in a return of the infection.
