As discussed in our guide to what cystitis is, the condition occurs in several forms. Mild cases — particularly those caused by irritants such as hygiene products or certain medications — may clear on their own within a few days. More severe cases caused by bacterial infection usually require prescription antibiotics.
If you have experienced cystitis before and are confident in your symptoms, the following home measures can help ease discomfort while you monitor whether the infection resolves naturally or seek medical 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. For mild cases, this may provide adequate relief while the infection clears naturally. 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.
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
The standard first-line antibiotics prescribed for uncomplicated acute cystitis are nitrofurantoin or trimethoprim. These come in tablet form and are usually prescribed for 3–7 days. See our full comparison: Nitrofurantoin vs Trimethoprim for UTIs.
Most people experience significant symptom relief within the first 24–48 hours of starting antibiotics. However, it is essential to complete the full prescribed course — stopping early risks the infection returning and increases the chance of developing antibiotic resistance.
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 rather than completing an online consultation.
💊 NICE First-Line Antibiotic
Nitrofurantoin (Macrobid)
MHRA-approved first-line antibiotic for cystitis & UTIs. Prescription via GPhC-regulated online consultation.
Order Nitrofurantoin →💊 Prescription Antibiotic
Trimethoprim
MHRA-approved alternative antibiotic for cystitis. Suitable where nitrofurantoin is not appropriate.
Order Trimethoprim →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 — particularly if your body reacts to a new medication or hygiene product — there are several evidence-based steps that reduce your risk:
- Drink plenty of water — especially important if you are undergoing chemotherapy or radiation therapy
- Go to the toilet promptly — delaying urination allows bacteria more time to multiply and can cause bladder irritation
- Shower rather than bath — those prone to cystitis have lower risk when showering versus bathing
- Wash gently — clean the skin around the vagina and anus with mild, unperfumed soap. Avoid harsh or heavily fragranced products
- Wipe from front to back — this prevents bacteria from the anal region reaching the urethra
- Urinate after sex — this flushes bacteria out of the urethra and significantly reduces post-coital UTI risk
- Wear breathable cotton underwear — avoid tight synthetic fabrics that create a warm, moist environment

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.
What can I do at home for cystitis?
Take paracetamol or ibuprofen for pain relief, drink plenty of water, rest, and avoid caffeine and alcohol. Cranberry products and probiotics may help, though evidence is limited. Home measures ease symptoms but do not treat bacterial infection.
How long does cystitis last?
Mild cases may resolve within a few days. With antibiotics, most cases clear within 24–48 hours of starting treatment, with full resolution by end of the course (typically 3–7 days). 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.
Can cystitis be treated with surgery?
Surgery is very rarely used and only considered in severe chronic cases where all other treatments have failed and quality of life is significantly impacted. Most cystitis is treated successfully with antibiotics.
How can I prevent cystitis from recurring?
Drink plenty of water, urinate after sex, wipe front to back, shower rather than bathe, avoid perfumed products near the urethra, and wear breathable underwear. If you have recurrent cystitis, speak to your GP about longer-term prevention options.
