This helps bladder muscles remain relaxed, decreasing the urge to urinate. As the muscles continue to relax, the bladder can also hold more urine to further extend the time between urination.<\/p>\n\n\n\n<div class=\"quick-facts-card\">\n  <table class=\"quick-facts-table\">\n    <colgroup>\n      <col\/>\n      <col\/>\n    <\/colgroup>\n\n    <thead>\n      <tr>\n        <th colspan=\"2\">Quick Facts<\/th>\n      <\/tr>\n    <\/thead>\n\n    <tbody>\n      <tr>\n        <td><strong>Common Brands<\/strong><\/td>\n        <td>Detrol (immediate release), Detrol ER (extended release)<\/td>\n      <\/tr>\n\n      <tr>\n         <td><strong>Drug Class<\/strong><\/td>\n        <td>Antimuscarinic\/anticholinergic<\/td>\n      <\/tr>\n\n      <tr>\n        <td><strong>Generic Status<\/strong><\/td>\n        <td>Generic version available<\/td>\n      <\/tr>\n\n      <tr>\n         <td><strong>Availability<\/strong><\/td>\n        <td>Prescription only<\/td>\n    <\/tbody>\n  <\/table>\n<\/div>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-dosing\">Dosing<\/h2>\n\n\n\n<p>Your dosing schedule for tolterodine depends on whether you are taking the immediate release or extended release formulation:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Immediate-release (IR): <\/strong>Patients typically take tolterodine IR twice daily: once in the morning and once in the evening. The standard starting dose is 2 mg twice daily, but your doctor may adjust the dosage to 1 mg twice daily based on your tolerance.<\/li>\n\n\n\n<li><strong>Extended-release (ER): <\/strong>Tolterodine ER is designed to release medication slowly over a 24-hour period. Patients typically take one 4 mg once daily, though doctors may reduce the daily dosage to 2 mg based on your tolerance.<\/li>\n\n\n\n<li><strong>Medical history: <\/strong>Providers generally start patients on a lower dose if they have significant liver or kidney impairment, or if they are taking other medications that interact with liver enzymes.<\/li>\n<\/ul>\n\n\n\n<p><em><strong>Note:<\/strong> The dosing information below is for educational purposes only.

Serious side effects from taking tolterodine can include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Angioedema: <\/strong>Tolterodine has been linked to this severe reaction, which causes swelling of the face, lips, tongue, and throat.<\/li>\n\n\n\n<li><strong>Urinary retention: <\/strong>If the medication is unable to empty the bladder, this can lead to severe abdominal pain.<\/li>\n\n\n\n<li><strong>Heart rhythm changes: <\/strong>In rare instances, tolterodine can cause a rapid or irregular heartbeat.<\/li>\n\n\n\n<li><strong>Confusion or delirium: <\/strong>This medication may impair cognitive function, especially in older adults.<\/li>\n\n\n\n<li><strong>Worsening glaucoma: <\/strong>Tolterodine may increase intraocular pressure in people with narrow-angle glaucoma.<\/li>\n<\/ul>\n\n<\/div>\n\n\n\n<p class=\"has-muted-color has-text-color\" style=\"font-size:0.875rem\"><em>Call your doctor immediately if you experience any concerning or prolonged symptoms.<\/em><\/p>\n\n\t<\/div>\n<\/section>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-pharmacist-tips\">Pharmacist Tips<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-manage-dry-mouth\">Manage Dry Mouth<\/h3>\n\n\n\n<p>Dry mouth is a common side effect of tolterodine. Taking frequent sips of water can help alleviate this issue.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-swallow-the-er-capsule-whole\">Swallow the ER Capsule Whole<\/h3>\n\n\n\n<p>Like other extended-release medications, tolterodine ER is intended to be swallowed whole.

Still, many won&#8217;t notice the medication&#8217;s full effects and therapeutic benefits for at least 4 to 8 weeks.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-be-cautious-with-certain-side-effects\">Be Cautious With Certain Side Effects<\/h3>\n\n\n\n<p>Since tolterodine can cause blurred vision and dizziness, patients are advised to monitor these side effects during the first few days of treatment. If the effects are severe, the patient may need to adjust their schedule to avoid driving or operating machinery after dosage time.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-consistency-is-key\">Consistency Is Key<\/h3>\n\n\n\n<p>Standard guidelines for tolterodine recommend taking each dose at the same time every day.
