Trimethoprim is an antibiotic medicine. It is used in the treatment of various bacterial infections, including cystitis. The medication has been noted for its fast mechanism of response, and its ability to reduce symptoms quickly. This item is sold as a generic tablet and oral suspension fluid, but the same medication has previously been made by GlaxoSmithKline under the names Proloprim and Triprim.

  1. Fast-functioning medicine for cystitis infections
  2. Available as an easy-to-use oral suspension
  3. Simple twice-a-day treatment.

It is thought that most will women will encounter cystitis at some point in their lives. The condition can be brought on by the presence of certain bacteria in the urinary tract, and can cause inflammation and feelings of pain in the bladder, as well as urinary discomfort. Some may notice that their urine becomes dark or discoloured too.

There are a number of reasons why someone might develop cystitis; but many of them involve the transfer of bacteria from other parts of the body, or from foreign objects, to the vagina. Bathroom habits (such as wiping from the anus to the vagina) can induce infection, as can sex, or the use of tampons or vaginally-inserted contraceptive devices.

Milder cases of cystitis may clear up without the need for treatment. In some instances, the body’s immune system is able to tackle the infection and stop it from developing. However, persistent or severe incidences of the illness will usually necessitate a course of medication.

For bacterial infections, antibiotics are the go-to option. This is because they eliminate the illness by combating the bacteria responsible. Trimethoprim is one medicine often designated for cystitis, and is available as a standard tablet, as well as an oral suspension treatment. It can also be employed as a preventative measure for those who are susceptible to recurrent infections.

Trimethoprim and Trimethoprim Oral Suspension work by stopping the growth of the offending bacteria. This is done by inhibiting their capacity to duplicate themselves through the production of DNA material. Once the bacteria is no longer able to spread, the immune system takes over and destroys what remains of the infection.

We know that it can be tough talking to your doctor in person about certain illnesses. We also know that not everybody likes to wait days to get an appointment. This is why we offer our customers a quick and easy service, so they can get fast access to the treatment they need. All you need to do is choose your medicine and take our short questionnaire. One of our physicians will review your answers, and issue a prescription if they are satisfied the medication is safe for you.

Active Ingredient

The functioning constituent in both versions of this medicine is Trimethoprim. This is a bacteriostatic antibiotic, which means that it disables the target bacteria’s ability to self-replicate. It has been marketed under various names by GlaxoSmithKline, but the edition available here is a generic medicine. Aspen also sell the medication as a combination with co-trimoxazole, under the name Septrim.

To spread, bacteria need to reproduce, and they do so by copying their own DNA material. To create the right conditions to do this, they need to generate folic acid. Trimethoprim stops the bacteria from multiplying in numbers by preventing them from synthesising this acid. As a result, the bacteria becomes prone to attack from the immune system, which kills off their remaining number.

If you want to find out whether Trimethoprim can help you, take our online medical survey. One of our qualified prescribing doctors will check your answers, and issue your medication if they are satisfied it is suitable for you. Following confirmation, we’ll have your order ready at your door in just one working day.
