The full name of Tolterodine is Tolterodine Tartrate. In clinical practice, there are very few cases of long-term use of tolterodine tartrate, so there is a lack of data on its long-term use to assess whether it can be taken for a long period of time, so long-term use is not recommended. Tolterodine tartrate antagonizes M-type cholinergic receptors and relieves bladder overactivity, and may treat symptoms such as urinary frequency, urgency, and urgency incontinence due to bladder overstimulation. Adverse reactions such as dry mouth, headache, drowsiness, urinary incontinence, dyspepsia, sensory abnormalities, decreased tearing, and blurred vision may occur after administration. Caution should be exercised while taking the drug such as driving a vehicle or operating machinery because it may cause blurred vision and drowsiness. The drug may interact with fluoxetine, erythromycin, clarithromycin, ketoconazole and other drugs in combination. It is contraindicated in the following cases: hypersensitivity to the drug; gastric retention, urinary retention, uncontrolled narrow-angle glaucoma; myasthenia gravis; ulcerative colitis or toxic megacolon; pediatric patients. Use with caution in the following conditions: pregnant women; with autonomic neuropathy, renal hypoplasia, hiatal hernia. Nursing women should stop breastfeeding when using the drug. If you need to use the drug patients, please under the guidance of the doctor strictly follow the instructions of the doctor to take medication, do not self-medication.
