Basic product information

What is Vesicare?

Vesicare is an oral medicine used in adults for symptoms of overactive bladder. It comes in tablet strengths commonly used in the UK (often 5 mg and 10 mg tablets, depending on availability).

Who is it for?

Vesicare is generally used in adults with an overactive bladder condition causing bothersome urinary symptoms. Your clinician will confirm whether Vesicare is suitable for you based on your symptoms and medical history.

How Vesicare works (mechanism of action)

Overactive bladder symptoms occur when the bladder muscle (the detrusor) contracts too often or too strongly, causing urgent bladder sensations and frequent urination.

Solifenacin blocks muscarinic receptors (mainly the M3 receptor) in the bladder. This reduces involuntary bladder contractions and increases bladder capacity, leading to fewer episodes of urgency and reduced frequency.

Key point: Vesicare helps control symptoms rather than cure an underlying cause, so ongoing use may be needed as advised.

Pharmacokinetics (how your body handles the medicine)

Understanding how solifenacin is processed can help you take it correctly.

Typical use and what it is prescribed for

Vesicare is indicated for the treatment of symptoms of overactive bladder, which may include:

• Urinary urgency (a sudden, compelling need to urinate)
• Urinary frequency (needing to urinate more often than usual)
• Urge incontinence (leakage or wetting associated with urgency)

When you should expect benefit: Some people notice improvement within days, but the full effect may take several weeks. If symptoms do not improve, your healthcare professional may review your treatment plan.

Timing: how to take Vesicare

How often: Vesicare is usually taken once daily.

What time of day: Choose a time that helps you remember. Consistency helps you maintain stable symptom control.

How to take:

• Swallow the tablet whole with water.
• Do not crush or chew unless your clinician advises otherwise.

If you miss a dose:

• Take it when you remember on the same day.
• If it is close to your next scheduled dose, skip the missed dose.
• Do not take a double dose to make up for the missed tablet.

Food interactions (including what to expect)

Solifenacin tablets can generally be taken with or without food. However, individual absorption and stomach comfort can vary.

• If you experience stomach upset, try taking it with food or after a light meal.
• To minimise variability, take your dose at the same time each day.

Practical tip: Maintain hydration during the day, especially if you experience dry mouth (a common antimuscarinic effect).

Alcohol and medicine interactions

Alcohol: There is no single “always unsafe” rule for alcohol with solifenacin, but alcohol may worsen side effects such as dizziness or bladder symptoms in some people. If you notice increased drowsiness, light-headedness, or worsening urinary symptoms after drinking, consider limiting alcohol and spacing it away from your dose.

Other medicines that may interact are especially important for antimuscarinic medicines. Tell your healthcare professional and pharmacist about all medicines you take, including:

• Other antimuscarinic medicines (e.g., for overactive bladder, travel sickness, or certain allergies) – can increase side effects.
• Medicines that affect CYP3A4 (because solifenacin is metabolised by CYP3A4). Examples include some:
  • Antifungals (such as ketoconazole/itraconazole)
  • Macrolide antibiotics (such as clarithromycin)
  • HIV medicines (some protease inhibitors)
  • Some medicines for irregular heart rhythms
• Medicines that can also affect heart rhythm (QT-prolonging drugs). Your clinician will assess risk.
• Cholinergic medicines (used for conditions such as myasthenia gravis or Alzheimer’s disease) – may counteract effects.
• Medicines that reduce gut movement (constipation-causing medicines), because constipation is a potential side effect of antimuscarinics.

What to do: Do not start or stop other medicines (including over-the-counter products) without advice, particularly if you have glaucoma, problems passing urine, or bowel issues.

Dosing: usual adult dose

Dose depends on symptom severity and individual factors such as tolerability, kidney function, and liver function.

Common adult dosing patterns:

• 5 mg once daily (often the starting dose)
• 10 mg once daily (may be used if needed and if tolerated)

Dose adjustments in special situations:

• Kidney impairment: Your clinician may lower the dose depending on how well your kidneys work.
• Liver impairment: Your clinician may limit the dose and monitor closely.
• Medicines that interact strongly (e.g., strong CYP3A4 inhibitors): dose adjustments and careful monitoring may be required.

Important: Always follow the dose instructions given to you. If you have a history of urinary retention, bowel obstruction, or glaucoma, dosing decisions must be made carefully.

Safety profile: who should be cautious

Like all medicines, Vesicare can cause side effects. Many people tolerate it well, but some effects relate to the antimuscarinic action.

Common side effects

• Dry mouth
• Constipation
• Blurred vision
• Dry eyes
• Headache
• Indigestion
• Urinary tract symptoms may occur in some people

Less common but serious risks

Contact urgent medical help or seek prompt advice if you experience any of the following:

• Inability to urinate or a sudden worsening of difficulty passing urine
• Severe constipation, belly pain, vomiting, or signs of bowel obstruction
• Severe allergic reaction (swelling of face/lips, trouble breathing, rash)
• Glaucoma symptoms (eye pain, sudden blurred vision, halos around lights)
• Confusion or significant drowsiness, particularly in older adults

Who may be at higher risk

• People with urinary retention or significant difficulty emptying the bladder
• People with gastrointestinal blockage or severe bowel movement problems
• People with narrow-angle glaucoma
• People who are elderly or frail, due to higher sensitivity to anticholinergic effects
• People who take several medicines that can contribute to anticholinergic burden

Practical use tips (to improve comfort and results)

• Manage dry mouth: sip water regularly, sugar-free chewing gum, or sugar-free sweets (if suitable for you).
• Prevent constipation: aim for adequate fibre, fruit/vegetables, and fluid intake; maintain regular toilet routines.
• Hydration: drink enough during the day, but avoid excessive fluid right before bedtime if nocturia is a problem.
• Track symptom changes: consider a bladder diary (frequency, urgency, and leakage episodes) to evaluate whether the medicine is helping.
• Be cautious with hot weather: antimuscarinic medicines can reduce sweating in some people—heat illness risk may be higher.
• Driving and machinery: if you feel dizzy or have blurred vision, avoid driving or operating machinery until you feel safe.

Alternative options for overactive bladder (UK)

If Vesicare isn’t suitable or doesn’t work well enough, there are several alternatives. These options may be used alone or in combination:

Non-medicine approaches

• Bladder training and scheduled voiding
• Pelvic floor muscle exercises (often guided by a physiotherapist)
• Reducing bladder irritants (such as caffeine, fizzy drinks, and alcohol if they worsen symptoms)
• Weight management if relevant

Other medicine options

• Other antimuscarinics for overactive bladder (varying side-effect profiles)
• Mirabegron (a beta-3 agonist) is an alternative that works differently and may be considered for some people
• Combination treatment may be an option in specialist care

Why alternatives matter: Different medicines can suit different people depending on side effects, existing medical conditions, and other therapies.

Market and legal context in the United Kingdom

In the UK, medicines like Vesicare (solifenacin) are regulated and supplied under national medicines frameworks and pharmacy regulations. Your local pharmacist can provide advice on correct use, interactions, and managing side effects.
