For bacterial cystitis: complete a clinical consultation and take a short course of prescription antibiotics — nitrofurantoin (NICE first-line, 3–5 days) or trimethoprim (7 days). Drink at least 1.5–2 litres of water daily and take ibuprofen or paracetamol for pain. If symptoms haven't improved within 48–72 hours of starting antibiotics, contact your prescriber.

Treat Cystitis Online →How to Help Cystitis at Home
As discussed in our guide to what cystitis is, the condition occurs in several forms. Mild cases — particularly those caused by irritants — may clear on their own within a few days. Bacterial cystitis usually requires prescription antibiotics.
If you have experienced cystitis before and are confident in your symptoms, the following home measures can help ease discomfort while you seek treatment:
Take Painkillers
Over-the-counter analgesics such as paracetamol and ibuprofen cannot cure bacterial cystitis, but they can effectively ease the pain and discomfort of symptoms. Ibuprofen is more effective for the inflammatory component of UTI pain. Always read the patient information leaflet and check with a pharmacist if you are unsure whether a medicine is suitable for you.
Stay Well Hydrated
Drinking plenty of water helps dilute your urine and encourages more frequent urination — which flushes bacteria out of the bladder before infection becomes established. Aim for at least 1.5–2 litres of water daily. Avoid caffeine and alcohol during a cystitis episode, as these can irritate the bladder.
Consider Probiotics
Consumed through food (probiotic yoghurt, kefir, kombucha) or supplements, probiotics can support gut health and immune function. Some research suggests probiotics may help reduce recurrence of UTIs, though evidence remains limited and they should not replace medical treatment.
Avoid Sexual Intercourse
Penetrative sex can worsen urinary tract irritation and exacerbate symptoms. It is advisable to wait until all symptoms have fully resolved before resuming sexual activity.
Cranberry Products
Many women find cranberry juice or supplements helpful in easing symptoms or reducing recurrence. While scientific evidence is not conclusive, cranberry products are thought to prevent bacteria from adhering to the bladder wall. They are generally safe to try alongside conventional treatment but are not a substitute for antibiotics.
When Antibiotics Are Needed
You should seek medical advice and consider antibiotic treatment if any of the following apply:
- Symptoms have not improved within 3 days of home treatment
- You have blood in your urine, a high fever, or stabbing pains in your side or back
- You are getting cystitis very frequently (two or more times in 6 months)
- You are pregnant
- You are a man experiencing UTI symptoms

Do not delay if symptoms are severe: Blood in urine, fever above 38°C, loin or back pain, or nausea alongside UTI symptoms may indicate the infection has spread to the kidneys. This requires urgent in-person medical care — call your GP or go to urgent care.
Nitrofurantoin vs Trimethoprim: Which Antibiotic Is Right for You?
Both nitrofurantoin and trimethoprim are NICE-recommended for uncomplicated cystitis, but they are not interchangeable in all situations:
| Nitrofurantoin | Trimethoprim | |
|---|---|---|
| NICE position | First-line | Second-line (alternative) |
| Typical course | 3–5 days (100mg MR twice daily) | 7 days (200mg twice daily) |
| Take with food? | Yes — reduces nausea | With or without food |
| Kidney impairment | Avoid if eGFR <45 ml/min | Use with caution; dose adjustment |
| Pregnancy | Avoid at term | Avoid first trimester |
| Resistance concern | Lower | Higher in some areas |

Bladder Surgery for Cystitis
Surgery is very rarely used to treat cystitis. The various surgical options cannot guarantee full relief of chronic or interstitial cystitis symptoms, and may lead to other complications. Surgery is only discussed in very severe cases where symptoms are significantly impacting quality of life and all other treatments have been tried and failed.
How to Prevent Cystitis
Although cystitis cannot always be prevented, there are several evidence-based steps that reduce your risk:
- Drink plenty of water — especially important if you are undergoing chemotherapy or radiation therapy
- Urinate after sex — the most effective single step for reducing post-coital UTIs
- Wipe from front to back — prevents bacteria from the anal region reaching the urethra
- Shower rather than bath — those prone to cystitis have lower risk when showering
- Wash gently — mild, unperfumed soap only. Avoid harsh or heavily fragranced products
- Wear breathable cotton underwear — avoid tight synthetic fabrics
- Urinate promptly — do not delay when you need to go

Frequently Asked Questions
What is the fastest way to get rid of cystitis?
The fastest way to clear bacterial cystitis is a short course of prescription antibiotics — typically nitrofurantoin (NICE first-line) or trimethoprim. Most women notice significant improvement within 24–48 hours of starting treatment. Drinking plenty of water and taking ibuprofen for pain can help while waiting for the antibiotics to take effect.
Can cystitis go away without antibiotics?
Mild cases of cystitis — particularly those caused by bladder irritants rather than bacterial infection — may resolve on their own within a few days with good fluid intake. However, bacterial cystitis rarely clears without antibiotics in the vast majority of women. Waiting more than 3 days without improvement, or if you have severe symptoms, warrants antibiotic treatment.
How do I stop getting cystitis after sex?
Urinating immediately after sex is the single most effective step for reducing post-coital UTIs. Additional measures include staying well hydrated, showering rather than bathing, wiping front to back, and avoiding perfumed hygiene products. If you consistently develop UTIs after sex, speak to your GP about post-coital antibiotic prophylaxis.
How do I get rid of cystitis?
Mild cases may clear with hydration and pain relief. Most bacterial cystitis requires prescription antibiotics — nitrofurantoin or trimethoprim. If symptoms persist beyond 3 days, or you have severe symptoms (fever, blood in urine, back pain), seek medical attention promptly.
How long does cystitis last?
With antibiotics, most cases clear within 24–48 hours of starting treatment, with full resolution by end of the course (typically 3–7 days). Without antibiotics, mild cases may resolve in a few days; bacterial infections tend to persist and may worsen. Always complete the full course.
When should I see a doctor for cystitis?
See a doctor if symptoms haven't improved within 3 days; you have blood in urine, high fever, or back pain; you have frequent recurrences; you are pregnant; or you are a man with UTI symptoms. These situations require clinical assessment.
