Product information

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, but the same medication has previously been made by GlaxoSmithKline under the names Proloprim and Triprim.

It is thought that most women will encounter cystitis at some point in their lives. Men do encounter it, but it’s much less common. 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 (or penis). 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 most bacterial infections, antibiotics are the recommended treatment. This is because they eliminate the illness by combating the bacteria responsible. 

Trimethoprim is prescribed when the first-line treatments for cystitis, MacroBID and Nitrofurantoin, aren’t suitable (for example, if they’ve been used previously and haven’t worked, or if someone is allergic to them). If you haven’t consulted with a doctor about those first, you should do so before taking Trimethoprim.

Trimethoprim works by stopping the growth of the offending bacteria. It does this by inhibiting the capacity of bacterial cells 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.

Please note that men ordering this treatment from us will also receive a test pot in their parcel. A urine sample must be provided in this pot before treatment is started, and taken to a GP or sexual health clinic to be analysed.

Take our UTI questionnaire to have your case reviewed by one of our prescribers. They will give you the option to buy Trimethoprim online once your prescription has been approved. All orders are shipped by next-day delivery from our UK pharmacy.
