What is trospium chloride ER and how does it work?
Trospium chloride extended-release is an antimuscarinic (anticholinergic) urinary antispasmodic. It is FDA-approved to treat overactive bladder (OAB) with symptoms of urge urinary incontinence (leaking with a sudden urge), urinary urgency, and urinary frequency. The extended-release capsule is taken once daily.
It works by relaxing the smooth muscle of the bladder. By blocking acetylcholine at muscarinic receptors, it reduces the involuntary bladder contractions that cause the sudden, hard-to-control urge to urinate. It does not cure overactive bladder but helps manage the day-to-day symptoms.
How much does trospium chloride ER cost without insurance?
The good news is that trospium chloride ER is a generic, so it is typically far less expensive than a brand-name equivalent. The original brand, Sanctura XR, has been discontinued in the U.S., which makes the generic the standard option. Even so, cash prices for the exact same generic capsule can differ significantly from pharmacy to pharmacy, which is why it pays to compare before you fill.

Alternatives and how trospium compares
Trospium is one of several medicines used for overactive bladder. Other anticholinergic options include oxybutynin, tolterodine, solifenacin, darifenacin, and fesoterodine. A different class of OAB medicine, the beta-3 agonist mirabegron, works by a separate mechanism and may be considered when anticholinergic side effects are a concern.
One practical difference is that trospium is a larger molecule that does not readily cross into the brain, so some clinicians choose it when they want to limit central nervous system effects, especially in older adults. Which medicine is right for you depends on your symptoms, other health conditions, and the other drugs you take. This is not medical advice, so talk with your doctor or pharmacist about the best fit.
Safety and side effects
Trospium chloride ER has no boxed warning. The most common side effects are dry mouth and constipation; it can also cause blurred vision, dizziness or drowsiness, and reduced sweating that raises the risk of overheating in hot weather. Because it can affect alertness, use caution when driving or operating machinery until you know how it affects you. For the extended-release capsule to be absorbed properly, take it on an empty stomach at least one hour before a morning meal, since food reduces how much drug your body absorbs.
Trospium should not be used by people with urinary retention, gastric (stomach) retention, or uncontrolled narrow-angle glaucoma, or by anyone allergic to trospium. Use caution if you have significant bladder outflow obstruction, GI obstruction, ulcerative colitis, intestinal atony, or myasthenia gravis. Angioedema (swelling of the face, lips, tongue, or throat) has been reported, sometimes after the first dose, and needs immediate medical attention and stopping the drug. Trospium adds to overall anticholinergic burden, so extra caution is warranted in older adults and in people taking other anticholinergic medicines; a dose adjustment may be needed with severe kidney impairment.
