Patient Information Leaflet

For more information on the prescription medication patients should refer to the Trimethoprim patient information leaflet.

Trimethoprim is an antibiotic. It is used to treat infections with bacteria.

Bacterial grow and multiply by producing genetic materials for the cells. The bacteria need folic acid to grow the genetic material. Unlike humans that take up folic acid from the diet, bacteria synthesize folic acid themselves. Trimethoprim works by stopping the folate production by the bacteria. With no folate produced, the bacteria will not be able to produce the genetic material necessary for their growth and multiplication. By preventing the bacteria from producing folate, trimethoprim stops the spread of infection in the human body. The remaining bacteria will eventually die or are killed by the immune system.

The doctor should make sure that the bacteria causing the infection are susceptible to trimethoprim before prescribing the medication. The doctor may take a tissue sample from the infected area and the bacteria present in the sample will be cultured and examined later for identification.

When administered to a patient with an infection caused by bacteria that are susceptible to trimethoprim, the bacteria will be deprived of their ability to produce folic acid, which the bacteria will synthesize to produce the genetic material necessary for growth and multiplication.

Trimethoprim stops the growth and multiplication of the bacteria, arresting the infection.

Doctors must make sure that the bacteria causing the infection are susceptible to trimethoprim, otherwise the infection will not be treated.

Trimethoprim is effective in stopping the growth and multiplication of bacteria that caused the infection.

Trimethoprim Tablets

Trimethoprim is taken by mouth as a tablet or as a suspension. The dose of the medication, how often it needs to be taken, and how long it must be taken depends on the type and the severity of the infection. It is also determined by your kidney function.

You should follow the instructions given by your doctor. The instructions on how to take trimethoprim are also printed in the dispensing label that comes with the medication.

Trimethoprim can be taken with or without a meal.

Trimethoprim should be taken at regular intervals. This will ensure that there is the same amount of medication in your bloodstream. If you forget to take a dose of trimethoprim, take it as soon as you remember. However, if it will be too close to your next dose, just skip the missed dose.

Unless instructed by your doctor, you need to finish the prescribed course of treatment even if you start to feel better. Stopping the course of treatment before its completion increases the risk of the infection coming back, with the bacteria becoming resistant to the antibiotic.

Trimethoprim 200mg

Trimethoprim is normally taken once in the morning and once in the evening, with a meal or without a meal.

Trimethoprim Dose

The usual dose of trimethoprim is as follows:

  • For the treatment of water infections – 200 mg two times a day. Your doctor may prescribe the first dose at 400 mg two times a day on the first day.
  • For the prevention of infections – 100 mg once a day.
  • For the treatment of cystitis that appears after having sex – 1 dose of 100 mg.
  • For the treatment of acne – 300 mg two times a day. The doctor may reduce the dose over time.

The dose of this antibiotic depends on your infection, your age, and how well your kidneys work. Elderly people and individuals with kidney problems are typically prescribed lower doses of the medication.
