Other measures which can help cystitis
- Increase the amount of water you are drinking each day to 2-3 liters (4-5 pints, or 10-12 glasses or mugs).
- Avoid alcohol, caffeine, and fizzy drinks which can irritate the bladder.
- Take paracetamol or ibuprofen for pain if necessary.
Sometimes cystitis will go away by itself in a few days without antibiotic treatment. If symptoms are mild, self-treatment and ‘wait-and-see’ for a few days may be the best approach. If symptoms are severe, or worsening, antibiotics are usually preferred. Women who have repeated infections will usually know if their symptoms are likely to stop on their own.
