Severe urinary frequency after taking Tolterodine Tartrate may be due to the fact that the medication has not fully worked or the medication used is not appropriate. Tolterodine tartrate is used to relieve the symptoms of urinary frequency, urgency and urge incontinence in overactive bladder syndrome and is usually recommended to be taken for 2 to 4 weeks. If the medication is not used for a sufficient period of time, the medication may not be working and the symptoms of frequent urination may still be severe. In addition, it is also possible that the medication does not match the disease, such as urinary tract infections caused by frequent urination, but also need to be combined with antibiotics in order to play a better role. Tolterodine tartrate may not work as well for frequent urination caused by stress or anxiety, and oral anti-anxiety medication may be needed. If the symptoms of frequent urination are not alleviated by taking Tolterodine Tartrate, it is necessary to visit the hospital in time to identify the specific cause of the disease, and then choose the appropriate treatment plan. The drug should be applied under the guidance of a doctor.
