Fesoterodine
Toviaz contains an active substance called fesoterodine fumarate and is a treatment for so-called antimuscarinics, which reduces the activity of overactive bladder and is used in adults to treat symptoms. Fesoterodine is a specific competitive antagonist of muscarinic receptors. It is rapidly and extensively hydrolyzed by nonspecific plasma esterases giving rise to the 5-hydroxymethyl derivative, which is the major active metabolite and is primarily responsible for the pharmacological action of fesoterodine. The recommended starting dose of Toviaz is one 4 mg tablet daily. Depending on how you respond to the medicine, your doctor may prescribe a higher dose; one 8 mg tablet daily. You should swallow the tablet whole with a glass of water. Do not chew the tablet. Toviaz can be taken with or without food.

Fesoterodine (Toviaz) Tablets for Urinary Symptom Relief
Fesoterodine (sold under the brand name Toviaz) is an antimuscarinic medicine used to reduce symptoms of an overactive bladder, such as urinary urgency, frequent urination and urge incontinence. It works by relaxing the bladder muscle so it can hold urine more comfortably without triggering sudden urges. Many adults choose Fesoterodine tablets when they want steady symptom control and better day-to-day bladder management.
You can order Fesoterodine tablets online from Pharmacy Planet after completing a short consultation reviewed by a UK prescriber. If you're looking for an effective incontinence treatment that supports urgency reduction and frequency control, Fesoterodine tablets are worth considering.
What Are Fesoterodine (Toviaz) Tablets?
Fesoterodine tablets are antimuscarinic medicines used to treat urinary disorders linked to an overactive bladder. They reduce bladder muscle activity, lower the number of sudden urges and support a more predictable bladder pattern. The medicine is converted in the body into an active metabolite that relaxes the bladder muscle throughout the day. This makes it useful for adults who experience strong urgency episodes or frequent urination that disrupt daily life.
Common Uses Include:
- Urinary urgency.
- Increased daytime frequency.
- Urge urinary incontinence.
- General bladder overactivity in adults.
How Do Fesoterodine Tablets Work?
Fesoterodine blocks muscarinic receptors in the bladder that normally trigger bladder contractions. By blocking these receptors, the bladder muscles relax and can hold more urine without sending sudden urgent signals. After you swallow the tablet, the body quickly converts Fesoterodine into its active form, which reduces bladder contractions. This active form lowers urinary urgency, leakage and frequent bathroom visits. The medicine is formulated to work steadily throughout the day, making it suitable for daily control of overactive bladder symptoms.
How to Use Fesoterodine Tablets?
Take Fesoterodine tablets exactly as instructed during your consultation. Swallow the tablet whole with a glass of water. Do not chew or crush the tablet.
Useful Tips for Best Results:
- Take Fesoterodine tablets at the same time each day.
- Swallow each tablet whole with water.
- Keep a routine so your body adjusts to the medicine.
- Do not take more than one tablet per day.
- Report new or persistent symptoms to your prescriber.
The usual starting dose for adults is 4 mg once daily. If your symptoms require stronger control and the medicine is well tolerated, your prescriber may increase the dose to 8 mg once daily. Never change your dose without consulting your prescriber. If you miss a dose, take it as soon as you remember unless it is close to the next scheduled dose. Do not take two doses together.
Who Can Use Fesoterodine Tablets?
Fesoterodine tablets may be suitable for:
- Adults diagnosed with overactive bladder symptoms.
- People experiencing strong or frequent urgency episodes.
- Individuals wanting a once-daily bladder relaxant.
- Adults with urinary leakage linked to OAB.
Fesoterodine tablets are not suitable for:
- Anyone allergic to Fesoterodine or similar antimuscarinic medicines.
- People with urinary retention or a blocked bladder outlet.
- Individuals with uncontrolled narrow-angle glaucoma.
- People with severe gastrointestinal conditions or reduced gut movement.
- Those with significant liver or kidney impairment unless reviewed carefully.
- Anyone taking strong CYP3A4 inhibitors unless dose adjustments are made.
Possible Side Effects of Fesoterodine Tablets
Many people tolerate Fesoterodine well, but some may experience side effects.
Very Common Side Effects:
- Dry mouth
Common Side Effects:
- Dry eyes, constipation, indigestion, pain or discomfort when urinating, dizziness, headache, stomach discomfort, diarrhoea, nausea, difficulty sleeping, throat dryness
Uncommon Side Effects:

Rare Side Effects:

Stop taking the medicine and seek medical help immediately if you notice swelling of the face, lips, tongue or throat, difficulty breathing or signs of a severe allergic reaction.
Can Fesoterodine Tablets Interact with Other Medicines?
Fesoterodine can interact with certain medicines, so it is important to tell your prescriber about everything you are taking before you start treatment. Some medicines can raise the level of Fesoterodine in your body, while others may make side effects like dry mouth, constipation or dizziness more likely.
Medicines That Need Extra Care:
- Strong inhibitors of liver enzymes (such as some antifungal or antibiotic medicines).
- Other antimuscarinic medicines used for bladder symptoms.
- Medicines that may cause constipation or reduce gut movement.
