Fesobig 4 Tablet 10 is used to manage symptoms of overactive bladder, including a sudden urge to urinate, frequent urination and urge urinary incontinence. It contains fesoterodine fumarate. It belongs to the class of medicines called antimuscarinic agents.
Overactive bladder occurs when the bladder muscle contracts involuntarily or too often, causing difficulty controlling urination. This medicine works by blocking muscarinic receptors in the bladder, helping relax the bladder muscle, improve urine storage capacity and reduce urinary urgency, frequency and accidental urine leakage.
Take this medicine exactly as prescribed by your doctor. Swallow the tablet whole and do not crush, chew or divide it. It may be taken with or without food. Do not increase or reduce the dose without consulting your doctor.
Tell your doctor if you have difficulty passing urine, severe constipation, narrow-angle glaucoma, myasthenia gravis, or liver or kidney problems. Seek immediate medical attention if you develop inability to urinate, severe constipation, swelling of the face, lips or tongue, breathing difficulty or other signs of a serious allergic reaction.

Interactions of Fesobig 4 Tablet 10
Drug-Drug Interactions

- Antitubercular medicines (e.g., rifampicin, rifabutin): These medicines may reduce fesoterodine levels in the body and decrease treatment effectiveness by increasing its breakdown. Your doctor may monitor symptom control during combined therapy.
- Antiepileptic medicines (e.g., carbamazepine, phenytoin): These medicines may increase the metabolism of fesoterodine and reduce its effectiveness. Your doctor may monitor treatment response if used together.
- Strong CYP3A4 inhibitors (e.g., ketoconazole, itraconazole): These medicines may increase fesoterodine levels in the body and raise the risk of side effects such as dry mouth, constipation, blurred vision, and urinary retention. Your doctor may adjust the dose during combined treatment.
- Other antimuscarinic medicines (e.g., oxybutynin, tolterodine): Taking similar medicines together may increase the risk of dry mouth, constipation, blurred vision, and urinary retention due to additive anticholinergic effects.
