The information provided in the summary table is for reference only. It is important to consult a qualified healthcare professional before starting any cystitis treatment, including Trimethoprim.

How does Trimethoprim work?

The drug is referred to as a bacteriostatic antibiotic, and it works by inhibiting the DNA synthesis of bacteria by reducing levels of tetrahydrofolic acid. This process serves to prevent the multiplication and spread of bacteria, eventually killing them off. The treatment should clear your infection up after a couple of days. If it doesn’t, you may need to seek further medical advice.

Why should I alternate the antibiotics for my cystitis?

There are antibiotic-resistant bacteria present in the body. For example, with cystitis, the bacteria tend to be more resistant to Trimethoprim than Nitrofurantoin. So, when you are taking repeated courses of antibiotics to treat urine infections, it is crucial to alternate the antibiotics to help reduce the development of resistance.

Trimethoprim alternatives

Besides Trimethoprim, various other antibiotics are commonly used to treat UTIs. Macrobid and the generic version of Macrobid, known as Nitrofurantoin, are also available as treatments for UTIs.

For other symptoms of cystitis, you can turn towards over-the-counter remedies. For instance, you can take OTC painkillers such as ibuprofen and paracetamol for relief from inflammation and pain due to UTIs.


What dose should I choose?

The treatment comes in tablet form, and usually one tablet is taken twice a day. However, additional doses may sometimes be required. If you complete an online consultation on our website, our specialist medical team can recommend the best dosage for you. You can also get more information on this topic by contacting your doctor or speaking to one of our healthcare experts.

How should I take Trimethoprim?

You can take Trimethoprim on an empty stomach or with a meal. For the best results, you should aim to take the tablets at the same times each day.
