Can solifenacin be taken long-term?
In general, patients whose medical condition requires it and who are assessed as safe by a physician may take solifenacin long-term. However, long-term use is not recommended for those with contraindications or intolerance. If in doubt, it is advisable to consult a doctor in advance. Detailed analysis is as follows:

If you have a chronic condition such as overactive bladder that requires long-term management, and your symptoms improve significantly after taking solifenacin without serious adverse effects during regular check-ups, long-term use may be considered appropriate under medical supervision. The drug helps stabilize bladder function, and continued use can effectively alleviate symptoms such as frequent urination and urgency, thereby improving quality of life.
Long-term use of solifenacin is not recommended if you have severe liver or kidney impairment, narrow-angle glaucoma, or other contraindications, or if you experience intolerable side effects such as dry mouth, constipation, or blurred vision. Taking the drug in these cases may worsen underlying conditions, and prolonged use in intolerant individuals may lead to cumulative adverse effects, impairing bodily functions; thus, an alternative treatment plan should be adopted.
Solifenacin must be taken strictly according to medical instructions—do not independently decide to continue or discontinue long-term use. Regular follow-up tests for liver and kidney function and eye health are necessary to monitor for adverse reactions. Inform your doctor promptly if any discomfort occurs, so that the treatment regimen can be adjusted accordingly.
