Description
Fesobig tablet is a medicine used in adults to manage symptoms of an overactive bladder, including frequent urination, sudden urges to urinate, and accidental urine leakage. By helping the bladder hold more urine and reducing involuntary contractions, it improves bladder control and quality of life.
It works by blocking specific receptors in the bladder called muscarinic (M3) receptors. This relaxation of the bladder muscles reduces involuntary contractions, increases bladder capacity, and helps control sudden urges and leakage, making daily activities more comfortable.
Fesobig tablet should be taken exactly as prescribed by your doctor. Swallow the tablet whole with water, preferably with or after a meal to reduce stomach upset. Taking it at the same time every day ensures optimal symptom control and minimizes side effects.
Some people may experience mild side effects such as dry mouth, constipation, dizziness, blurred vision, drowsiness, headache, or stomach discomfort. Most side effects are manageable, but you should contact your doctor if they persist or become troublesome.
This medication may interact with other drugs, particularly those that affect liver enzymes or have anticholinergic effects, such as certain antidepressants, antibiotics, antifungals, or Parkinson’s medications. Always inform your doctor about all medications, supplements, or herbal products you are taking to ensure safe and effective treatment.

Mode of Action
How Does It Work?
Fesoterodine works by blocking muscarinic (M3) receptors in the bladder. This relaxes the bladder muscle, reduces involuntary bladder contractions, increases bladder capacity, and helps control symptoms such as urgency, frequent urination, and urge urinary incontinence....
Interactions
Interactions with other medicines
- Taking fesoterodine with other medicines that have similar anticholinergic effects (such as some antidepressants, medicines for Parkinson’s disease, or certain antipsychotics) may increase side effects like dry mouth, constipation, sleepiness, blurred vision, or difficulty passing urine....
- Fesoterodine may reduce the effect of medications that promote gastrointestinal motility, such as metoclopramide.
- Strong medicines that block liver enzymes (CYP3A4 inhibitors), such as ketoconazole, itraconazole, clarithromycin, and ritonavir, as well as similar antiviral or antifungal drugs, can increase the level of fesoterodine in the body, thereby increasing the risk of side effects. In such cases, the dose of fesoterodine is usually kept low....
- Medicines that moderately affect liver enzymes, such as erythromycin, fluconazole, diltiazem, verapamil, or grapefruit juice, may slightly increase fesoterodine levels, but dose changes are usually not required....
- Medicines that strongly increase liver enzyme activity (CYP3A4 inducers) such as rifampicin, carbamazepine, phenytoin, phenobarbital, or St John’s Wort can reduce the effect of fesoterodine, making it less effective. These combinations are generally not recommended....
- Some medicines that block another liver enzyme (CYP2D6 inhibitors) may increase fesoterodine levels in the body, potentially leading to more side effects. A lower dose may be needed in such cases.
- Fesoterodine does not reduce the effectiveness of oral contraceptive pills and does not interfere with birth control hormones.
- Fesoterodine does not significantly affect the action or blood-thinning effect of warfarin.
- Interaction studies with fesoterodine have been conducted only in adults; data in children are limited.
Interactions with food items
