  • What is cystitis?

    Cystitis is the name for bladder inflammation, usually caused by a bladder infection. 

    Mild cases of cystitis often improve within 3 days but more severe cases can last longer. If your symptoms do not improve within 3 days, you should speak to a doctor.

  • Can cystitis cause any complications?

    Cystitis in men is usually an indication of a more serious problem and requires medical help from your GP. It can also be caused by STIs which can have other complications. Men should see their GP if they suffer from cystitis.  

    Women can use treatment without face to face referral but if it doesn’t clear up, medical advice is needed. This is because if left untreated after it hasn’t cleared up, it can lead to a serious kidney infection.

  • What treatments are there for Cystitis?

    For milder cases, treatment with potassium citrate sachets may be sufficient. For more stubborn infections, a course of water infection tablets such as Trimethoprim may be required.

  • What is the best antibiotic for cystitis?

    This depends on what bacteria is causing your infection. The most common type of bacteria which causes uncomplicated UTI’s is E. coli. The antibiotics which are given to treat this bacteria are Trimethoprim or Nitrofurantoin. If your symptoms do not improve after completing a course of these antibiotics, it is important to see your GP to have your urine tested in case it is a different bacteria that needs a different antibiotic.
