Tolterodine reduces spasms in the bladder and is used to treat urinary incontinence and an overactive bladder.
Before taking tolterodine, inform your doctor of your medical history, especially if you’ve had glaucoma, myasthenia gravis, kidney or liver disease, a personal/family history of Long QT Syndrome, or if you have a blockage in your urinary tract, stomach, or intestine. Also tell your doctor what other medications you take and if you become pregnant or breast-feed. Take tolterodine with water. Do not break the pill; doing so may cause too much of the active ingredients to release at once.
Do not take this medication if you are allergic to tolterodine or fesoterodine. Use caution when driving or doing anything that requires alertness. Alcohol may increase side effects. Tolterodine may interact with other drugs, so let your doctor know what other medications you take, especially if you take narcotics, antibiotics, psychiatric medications, and heart rhythm medications.
Overdose symptoms include: dry mouth, blurry vision, fast heart rate. Seek medical attention immediately if you suspect an overdose or allergic reaction. Cease use and contact your doctor immediately if you experience a severe side effect such as: chest pain, fast/uneven pulse, confusion and hallucinations, urinating less than usual or not at all, and painful urination. Other side effects may occur, such as: dry mouth and eyes, blurry vision, dizziness, drowsiness, digestive issues, joint pain, and headache.
