What is Trimethoprim?
Trimethoprim is an antibiotic used to treat urinary tract infections. It is the most commonly the first treatment prescribed by doctors for uncomplicated lower urinary tract infections known as cystitis. This medication contains 200mg of the active ingredient which works to kill the bacteria which causes the infection.
Trimethoprim for UTIs
A urinary tract infection occurs when bacteria enters the urinary tract which is usually a bacteria-free environment. When the bacteria enters the lower urinary tract and causes inflammation, this is known as cystitis. The inflammation caused by the bacteria is what gives UTIs its characteristic symptoms of discomfort, urgently needing the bathroom, pain on urination and needing the bathroom frequently.
Bacteria can move further up the urinary tract and into the kidneys causing flank, back or side pain. If this happens seek medical attention immediately as it is a serious form of UTI known as an upper urinary tract infection.
When buying trimethoprim tablets online, only use the medicine for cystitis after an online assessment.
How does Trimethoprim work?
Trimethoprim works directly on the affected area travelling to the bladder. Here trimethoprim attacks the bacteria, preventing them from multiplying. This allows the immune system to come and clear the remaining bacteria and infection.
This is why it is recommended to take trimethoprim at night. It allows the medicine to remain in the bladder longer where it works effectively before leaving the body through the urine.
For urinary tract infections, the most common course is 3 days. One tablet is taken TWICE daily (every 12 hours). For more stubborn infections, it may also be prescribed for five days.
Trimethoprim will take start to relieve symptoms in as little as 24 hours although the full effect can take up to 3 days. If symptoms are still present after the 3-day course, consult your doctor as soon as possible for continued treatment or alternative antibiotics.
Even if symptoms go away before completing your course, you should make sure to finish the tablets prescribed. This is to make sure the infection has been completely cleared, reducing the risk of it coming back. Stopping your course early can lead to resistance to trimethoprim in the bacteria, known as antibiotic resistance.
