Vesicare (Solifenacin) – Patient Guide (UK)

Vesicare contains solifenacin, a medicine used to treat certain bladder problems. If you have symptoms such as a sudden, urgent need to urinate or frequent urination, Vesicare may help reduce overactive bladder symptoms.

This guide explains what Vesicare is, how it works, how to take it, important safety information, and practical tips to get the most from treatment—tailored for people in the United Kingdom.

Basic product information

What is Vesicare used for?

Vesicare is indicated for symptoms of overactive bladder, including:

• Urge incontinence (a sudden need to urinate followed by leakage)
• Urgency (needing to urinate urgently)
• Increased frequency (needing to urinate more often than usual)

It is generally used when these symptoms are due to bladder overactivity, and when lifestyle measures alone have not been enough.

How Vesicare works (mechanism of action)

Solifenacin belongs to a group of medicines called antimuscarinics (also known as anticholinergics). In the bladder, nerve signals help trigger bladder contractions—especially the sudden strong “urge” to urinate.

Solifenacin blocks muscarinic receptors in the bladder (particularly the M3 receptor). This reduces involuntary bladder muscle contractions and helps the bladder hold urine more comfortably, leading to fewer episodes of urgency and leakage.

Pharmacokinetics: how the body absorbs and processes it

Pharmacokinetics describes what the body does with a medicine after you take it.

• Absorption: Solifenacin is absorbed after oral dosing. Peak blood levels typically occur after several hours.
• Distribution: It distributes through the body tissues, including the bladder.
• Metabolism: Mainly metabolised in the liver.
• Elimination: Excreted primarily through the kidneys and, to a lesser extent, via other routes.
• Half-life: It is designed for once-daily dosing to maintain effective levels throughout the day.

Note: Individual exposure may be higher in people with certain medical conditions (for example, kidney or liver impairment), which can increase the risk of side effects.

When and how to take Vesicare (timing and dosing)

Vesicare is taken once daily, at the same time each day if possible.

Typical dosing in adults

• Most adults: commonly start with 5 mg once daily.
• Some adults: may be increased to 10 mg once daily if appropriate and tolerated.

Important: Your exact dose may differ depending on your age, symptom severity, and other health conditions.

How to take it

• Swallow the tablet whole with water.
• Try not to crush or chew tablets unless your pharmacist or prescriber advises it.
• If you miss a dose, take it when you remember—unless it is close to your next dose. Do not take a double dose.

How long it takes to work

Many people begin to notice improvement within the first couple of weeks, but benefits may continue over a period of up to several weeks. If symptoms do not improve, speak to a healthcare professional before changing your dose or stopping.

Food interactions and what to expect with meals

Vesicare can generally be taken with or without food. Food does not usually require special timing adjustments.

• With meals: You may take it after food if this helps you tolerate it.
• Consistency: Taking it at about the same time each day can help maintain steady symptom control.

If you notice stomach discomfort or other side effects when taken on an empty stomach, consider taking it with a meal or snack and discuss persistent problems.

Alcohol interactions

While there is no single “universal” alcohol rule, alcohol can affect bladder symptoms and increase the risk of side effects.

• Bladder effects: Alcohol can irritate the bladder and increase urine production, potentially worsening urgency and frequency.
• Side effect overlap: Vesicare can cause dizziness or blurred vision in some people; alcohol can also affect alertness and balance.

Practical tip: If you drink alcohol, consider reducing intake and monitoring whether symptoms worsen. Avoid driving or operating machinery if you feel drowsy or lightheaded.

Medicine interactions: what to tell your pharmacist

Vesicare can interact with other medicines, mainly because it works through antimuscarinic pathways and because some drugs affect how solifenacin is metabolised in the liver.

Medicines that may increase side effects (antimuscarinics)

• Other medicines with antimuscarinic effects (for example, for bladder, bowel, allergy, or Parkinson’s symptoms)

Together, these can increase the likelihood of dry mouth, constipation, blurred vision, and difficulty passing urine.

Medicines that may increase solifenacin levels

Certain medicines can raise solifenacin blood levels by affecting liver enzymes, potentially increasing risk of side effects. Examples may include some:

• Antifungal medicines (azole antifungals)
• Some antibiotics (for example, certain macrolides)
• Medicines used for HIV or hepatitis treatment
• Some heart rhythm medicines

Medicines affected by antimuscarinics or that change bladder function

• Other drugs that affect urinary retention risk
• Medicines that may reduce bowel movement (constipation risk)

Always check before combining

Before starting Vesicare, ensure your pharmacist or healthcare professional knows about:

• All medicines you take (including over-the-counter products)
• Herbal supplements
• Your medical history (especially urinary problems and glaucoma)

Indications and who should be cautious

Vesicare is intended for overactive bladder symptoms. However, it may not be suitable for everyone.

People who may need extra caution

• Urinary retention or difficulty emptying the bladder
• Gastric problems (such as severe constipation or conditions that delay stomach emptying)
• Severe constipation (risk of worsening)
• Uncontrolled narrow-angle glaucoma
• Myasthenia gravis (a neuromuscular condition)
• Known hypersensitivity to solifenacin or tablet ingredients
• Kidney or liver impairment (dose adjustments or closer monitoring may be necessary)

If you are unsure whether any of these apply to you, ask a healthcare professional for advice before taking Vesicare.

Safety profile: side effects to watch for

Like all medicines, Vesicare can cause side effects. Many people experience mild effects that improve as the body adjusts.

Common side effects

• Dry mouth
• Constipation
• Blurred vision or visual changes
• Difficulty passing urine (especially in people with prostate enlargement or pre-existing bladder emptying issues)
• Indigestion or stomach discomfort
• Urinary tract symptoms in some people (not always caused by the medicine)

Seek urgent medical advice if you get

• Severe allergic reaction (swelling of face/lips, trouble breathing, widespread rash)
• Severe constipation with significant pain or inability to pass stool/gas
• Acute urinary retention (sudden inability to urinate)
• Eye pain, severe eye redness, or sudden vision changes (possible glaucoma-related symptoms)
• Confusion or marked drowsiness, especially in older adults

How age may affect risk

Older adults may be more sensitive to antimuscarinic medicines and may experience more side effects such as dizziness, confusion, constipation, and blurred vision. Careful dose selection and monitoring are important.

Practical use tips to reduce side effects

Managing dry mouth

• Sip water regularly
• Use sugar-free gum or lozenges
• Maintain good oral hygiene

Reducing constipation risk

• Increase fibre in your diet (whole grains, fruit, vegetables)
• Stay well hydrated
• Keep physically active where safe
• Consider a suitable stool softener/laxative only if recommended by a pharmacist, particularly if you have a history of constipation

Avoiding problems with urination

• Do not “ignore” reduced urine flow—report it promptly
• If you have prostate symptoms, monitor carefully and seek advice if urination becomes difficult

Vision and driving

• If you experience blurred vision or dizziness, avoid driving and using machines until it settles
• Tell your pharmacist if vision changes persist

Consistency matters

Try to take Vesicare once daily at a consistent time. If you frequently miss doses, symptom control may be less reliable.

Pharmacovigilance and recent guidance (UK context)

In the UK, medicines are monitored through the Yellow Card Scheme, allowing patients and healthcare professionals to report suspected side effects. If you experience side effects while taking Vesicare, reporting can help improve safety information.

Because safety profiles can evolve with new evidence, it’s a good idea to:

• Check the patient information leaflet included with your medicine
• Review safety information with your pharmacist if you are on multiple medicines
• Seek prompt advice if symptoms change or worsen after starting treatment

Alternative options for overactive bladder

If Vesicare is not suitable or does not work well, there are other treatment options commonly considered in the UK. These may include non-medicine approaches, other medicine types, or different antimuscarinics.

Non-medicine options

• Bladder training and timed voiding
• Pelvic floor muscle exercises (often with guidance)
• Reducing triggers (for example, caffeine or bladder irritants)
• Managing constipation and fluid timing

Other medicine options

• Other antimuscarinics (different medicines in the same class may suit some people better)
• Mirabegron (a beta-3 agonist) is a medicine used for overactive bladder and may be an alternative depending on your profile and tolerability

Choosing an alternative depends on your symptoms, medical history, and how you tolerate antimuscarinics. A pharmacist can help you understand which option may be more appropriate to discuss with a clinician.
