Trimethoprim is an antibiotic used to treat various bacterial infections. Its broad-spectrum nature allows it to target and eliminate a wide range of bacteria to prevent and treat various bacterial infections like cystitis and urinary tract infections (UTIs), offering a reliable solution for both immediate treatment and long-term management.

What Is Trimethoprim Used For?

Trimethoprim is an antibiotic primarily aimed at treating and preventing UTIs. Its effectiveness lies in targeting the bacteria that cause these infections, helping to alleviate common symptoms associated with UTIs, such as:

  • Burning during urination
  • Frequent urination
  • Abdominal pain

Trimethoprim is suitable for a range of other bacterial infections, like chest infections and acne.

How Does Trimethoprim Work?

Trimethoprim stops the spread of bacterial infections by blocking the bacteria’s ability to make folic acid, which they need to grow and multiply. This helps to treat the infection and ease symptoms.

What Dose of Trimethoprim Do I Need?

The typical dosage for adults and children over 12 years is 200mg, taken twice a day. For long-term treatment and prevention, the dose may be reduced to 100mg at night.

Who are Trimethoprim 200mg Tablets Suitable For?

Trimethoprim is suitable for most people needing treatment for bacterial infections, especially UTIs. However, it should not be used by those who:

  • Are allergic to any of its ingredients
  • Have certain blood disorders
  • Are pregnant
  • Have severe liver disease
  • Or in premature babies and babies in their first few weeks of life.

It’s also important to be cautious if you have kidney disease, are undergoing dialysis, or have a folic acid deficiency.

How to Take Trimethoprim 200mg Tablets

Trimethoprim 200mg tablets should be taken orally and swallowed whole with a glass of water.

For acute infections, such as bacterial cystitis, the typical duration of treatment ranges from 3 to 14 days. It’s essential to complete the full course of Trimethoprim, even if you start feeling better before the end of the prescribed period.

If you forget to take a dose of Trimethoprim, take it as soon as you remember. However, if it’s nearly time for your next dose, skip the missed dose and continue with your regular dosing schedule. Do not take a double dose to make up for a forgotten one, as this can increase the risk of side effects.

In cases of long-term treatment for preventing recurrent infections, follow the prescription carefully, as regular intake at the same time each day helps maintain consistent levels of the medication in your body, enhancing its effectiveness.
