Vesicare (Solifenacin) — Patient Information (UK)
Vesicare contains the active ingredient solifenacin, a medicine used to help control symptoms of overactive bladder. This guide is designed to help you understand what Vesicare does, how it works, how to take it, and what to watch for. It also covers interactions, practical tips, and frequently asked questions relevant to the United Kingdom.
Quick Facts
- Medicine: Vesicare
- Active ingredient: Solifenacin
- Common use: Helps with urgency, frequent urination, and sudden urges to pass urine
- Typical dosing frequency: Once daily
- Common strengths: Often 5 mg and 10 mg tablets (availability may vary)
- How it works: Antimuscarinic (anticholinergic) activity in the bladder
What is Vesicare and what is it used for?
Vesicare is used to treat overactive bladder (OAB). Overactive bladder is a condition where the bladder muscle becomes overactive, leading to troublesome urinary symptoms.
Typical symptoms include:
- Urgency: a sudden, difficult-to-delay need to urinate
- Urge incontinence: leakage on the way to the toilet (sometimes)
- Frequency: passing urine more often than you would like
- Nocturia: waking during the night to urinate
Vesicare helps reduce these symptoms by relaxing and stabilising bladder activity. It is intended for ongoing symptom control rather than immediate “as needed” relief.
How Vesicare works (Mechanism of Action)
Solifenacin belongs to a group of medicines called antimuscarinics (also known as anticholinergics). These medicines block certain receptors called muscarinic receptors.
In the bladder, muscarinic receptors are involved in bladder muscle contractions. By blocking these receptors, solifenacin can:
- Reduce involuntary bladder contractions
- Increase bladder capacity
- Reduce urgency and frequency
The result is fewer sudden urges to pass urine and fewer trips to the toilet.
Pharmacokinetics (How the body handles solifenacin)
Pharmacokinetics describes how the medicine is absorbed, distributed, broken down, and eliminated. The exact numbers can vary between individuals, but the following gives a practical overview:
- Absorption: Solifenacin is absorbed after oral dosing.
- Time to effect: Benefits often build over days; some people notice improvement within the first week.
- Protein binding: Solifenacin is significantly bound to plasma proteins.
- Metabolism: Primarily metabolised by the liver (notably the CYP enzyme system).
- Elimination: The medicine and its metabolites are eliminated mainly via urine and faeces.
- Half-life: Solifenacin has a long enough duration to support once-daily dosing.
If you have liver or kidney problems, you may require dose adjustment and closer monitoring.
Indications (When Vesicare is used)
Vesicare is indicated for the treatment of overactive bladder in adults. This typically includes symptoms such as urgency, frequency, and urgency incontinence.
Your clinician may consider other causes of urinary symptoms first (for example, urinary tract infections, bladder stones, or prostate issues), because these may require different treatment.
Dosing and how to take Vesicare
Vesicare is usually taken , with a consistent routine. The dose depends on your individual circumstances, symptom response, and tolerability.
Typical starting dose
- Common starting dose: 5 mg once daily
- May be increased: to 10 mg once daily for some patients if needed and if tolerated
Timing
- Take at the same time each day.
- Choose a time that suits your routine and hydration pattern.
- Many people take it in the morning or evening depending on symptom pattern (especially nighttime symptoms).
How to swallow
- Swallow tablets whole with water.
- Do not crush or chew unless your pharmacist confirms it is appropriate.
If you miss a dose
- If you remember later the same day: take it if it’s still close to your usual time.
- If it’s near the next dose: skip the missed dose.
- Do not take a double dose to make up for a missed tablet.
How long before it helps?
Some improvement may be seen within a few days, but full benefit may take several weeks. If there is little or no improvement after an appropriate trial, your healthcare professional may review the diagnosis, dose, and suitability of continued treatment.
Food interactions and meal advice
Solifenacin can be taken with or without food in many cases. However, individual absorption and tolerance may vary. As a practical approach:
- Consistency matters: take it the same way each day (with or without food).
- If you experience stomach discomfort, taking with food may be easier.
If you are using additional medicines, your pharmacist can advise on a schedule that reduces side effects.
Alcohol and medicine interactions
Alcohol doesn’t always “directly” interact with solifenacin in a simple way, but it can worsen side effects and reduce bladder control in some people. For best comfort:
- Limit alcohol, especially in the evening.
- Be cautious if you notice increased dry mouth, dizziness, or blurred vision after drinking.
- If you have a tendency toward urinary urgency or dehydration, alcohol may make symptoms more noticeable.
Important medicine interaction considerations: Vesicare can interact with other medicines that have antimuscarinic effects or can affect metabolism. Always review your full medication list (including over-the-counter products and herbal remedies) with a healthcare professional.
- Other antimuscarinics / anticholinergics: may increase risk of side effects (e.g., constipation, dry mouth, blurred vision).
- Medicines that affect liver enzymes (CYP): some drugs can increase or decrease solifenacin levels.
- Some treatments for bladder symptoms: combining may not be suitable.
- Drugs that can cause urinary retention: caution is advised in people prone to retention.
If you think you may be taking medications that could interact, speak to your pharmacist for a tailored check.
Safety profile and common side effects
Like all medicines, Vesicare can cause side effects. Many people tolerate it well, but antimuscarinics can affect the whole body’s “rest-and-digest” processes, leading to typical anticholinergic effects.
Common side effects
- Dry mouth (very common)
- Constipation
- Blurred vision
- Indigestion
- Headache
- Urinary symptoms changes (in some cases reduced urination can occur)
Less common but important effects
- Drowsiness or dizziness in some people
- Confusion, particularly in older adults or those with cognitive impairment
- Heat intolerance (reduced sweating can occur)
Seek urgent medical advice if
- You develop symptoms of urinary retention (unable to urinate despite feeling the urge)
- Severe constipation, severe abdominal pain, or vomiting occurs
- You experience eye pain and significant vision changes (rare but important)
- Allergic symptoms such as swelling of the face/lips or difficulty breathing occur
Practical use tips (to improve comfort and effectiveness)
Manage dry mouth
- Keep water nearby and sip regularly.
- Use sugar-free chewing gum or sugar-free sweets.
- Oral moisturisers may help if dryness is significant.
Reduce constipation risk
- Increase fibre in your diet and keep hydrated.
- Stay active—gentle daily movement can help bowel function.
- If constipation develops, speak to a pharmacist about appropriate stool softeners or fibre supplements.
Bladder training alongside medication
Vesicare can work best when combined with lifestyle measures such as:
- Scheduled toilet visits to reduce urgency episodes
- Gradually increasing time between bathroom trips (as advised)
- Pelvic floor muscle exercises (often called Kegels) if appropriate
Night-time symptoms
- Consider when you take your dose (morning vs evening) based on your main symptoms.
- Try to reduce large fluid intake close to bedtime.
- Avoid caffeine late in the day if it triggers urgency for you.
If side effects become troublesome, don’t stop suddenly without advice—your pharmacist or clinician may adjust the dose or consider a different option.
Special populations: kidney and liver impairment
Dose adjustments or extra caution may be required if you have reduced kidney or liver function. People with significant kidney impairment or significant liver disease may be advised to use a reduced dose and be monitored more closely.
- Kidney impairment: caution is advised; dosing may be lower in reduced function.
- Liver impairment: caution is advised; dosing may be limited, and certain severities may not be suitable.
Always consult your healthcare professional if you have a known kidney or liver condition.
Alternative options for overactive bladder (UK)
If Vesicare isn’t suitable or doesn’t provide enough benefit, there are alternative approaches. Options may include non-drug strategies and other medicines.
Non-medicine options
- Bladder training
- Pelvic floor muscle training
- Review of triggers such as caffeine, alcohol, constipation, and certain drinks
Other medicine options
- Other antimuscarinic bladder medicines (different agents within the same class)
- Beta-3 adrenoceptor agonists (a different mechanism class, for example mirabegron in some settings)
The best choice depends on your symptoms, side-effect tolerance, medical history, and existing medicines. Your clinician can advise which option fits you best.
