A Comprehensive Guide to Understanding and Using Trimethoprim Antibiotic

Trimethoprim is a commonly prescribed antibiotic used to combat a range of bacterial infections, primarily those affecting the urinary tract. 

Trimethoprim belongs to a class of antibiotics known as dihydrofolate reductase inhibitors. It works by disrupting the bacteria’s ability to produce folic acid, a vital nutrient for their growth and survival. By interfering with this process, trimethoprim effectively stops the bacteria from multiplying and allows the body’s immune system to clear the infection.

What Infections Does Trimethoprim Treat?

While trimethoprim is primarily used to treat urinary tract infections (UTIs), including cystitis (bladder infection) and kidney infections, it can also be prescribed to combat other bacterial infections, such as:

• Chest infections
• Acne
• Infections of the ear, nose, and throat
• Traveller’s diarrhoea

It is important to note that trimethoprim is only effective against bacterial infections and will not work against viral infections such as the common cold or flu.

How to Take Trimethoprim

Trimethoprim is available from Access Doctor in 200 mg tablets and is typically taken twice a day. However, your doctor will tell you if you need to take it more or less frequently. It is crucial to complete the entire course of any antibiotic medicine, including Trimethoprim, as your doctor prescribes, even if you start feeling better before finishing the whole medication packet. Stopping the treatment early can lead to the infection returning or the bacteria becoming resistant to the antibiotic.

The dosage and duration of treatment will depend on various factors, including the infection’s type and severity, age, and any underlying health conditions you may have. It is essential to follow your doctor’s instructions carefully and not exceed the recommended dosage.

Potential Side Effects

Like all medications, trimethoprim can cause side effects, although not everyone experiences them. Some of the most common side effects include:

• Nausea and vomiting
• Diarrhoea
• Skin rash or itching
• Headache
• Dizziness

These side effects are usually mild and resolve on their own. However, if you experience any severe or persistent side effects, it’s important to contact your doctor immediately.

Important Considerations

Before being prescribed trimethoprim, you will have an online consultation with one of our fully qualified medical prescribers. During your consultation, it is crucial to inform your Access Doctor consultant if you have any of the following conditions:

• Allergies to trimethoprim or any other medications
• Liver or kidney problems
• Anaemia or low levels of folic acid
• Porphyria (a rare blood disorder)
• Pregnancy or breastfeeding

Trimethoprim may not be suitable for everyone, and your Access Doctor medical consultant will assess your individual circumstances to determine if it is the right antibiotic to meet your needs.

Frequently Asked Questions

Can I drink alcohol while taking trimethoprim? Yes, you can drink alcohol while taking trimethoprim. However, it is advisable to consume alcohol in moderation, as excessive alcohol intake can weaken your immune system and potentially prolong the infection.

What should I do if I miss a dose? If you miss a dose, take it as soon as you remember unless it is almost time for your next dose. In that case, skip the missed dose and continue with your regular schedule. Do not take a double dose to make up for a missed one.   

What should I do if I experience side effects? It is essential to inform your doctor if you experience any side effects, even mild ones. They can advise you on whether to continue taking the medication or suggest an alternative treatment.

Can I take trimethoprim if I am pregnant or breastfeeding? Trimethoprim is generally considered safe to take during pregnancy and breastfeeding, but it is essential to discuss it with your doctor first. They will weigh the potential benefits against any risks and advise you on the best course of action.
