Trospium is a prescription medicine used to calm an overactive bladder. It lowers sudden urges, reduces leaks, and can cut down on bathroom trips during the day and night. People choose trospium when lifestyle changes and pelvic exercises don’t give enough relief.
Trospium belongs to a group called antimuscarinics. It blocks specific receptors in the bladder muscle so the bladder relaxes and holds urine better. Doctors commonly prescribe it for urge incontinence, urgency, and frequent urination caused by bladder spasms. The usual immediate-release dose is 20 mg twice daily, taken at least one hour before or two hours after meals. There’s also a 60 mg extended-release version taken once daily on an empty stomach. Always follow your prescriber’s instructions—doses change with age, kidney function, or other medicines.
Expect dry mouth, constipation, and blurred vision early on; these are the most common side effects. Less often, people report drowsiness, dizziness, or trouble starting to pee. If you notice severe confusion, chest pain, or very fast heartbeat, call your doctor right away. Don’t use trospium if you have urinary retention, severe stomach-blocking conditions, or untreated narrow-angle glaucoma.
Trospium is cleared by the kidneys, so your doctor will adjust or avoid it if you have severe kidney disease. It adds up with other anticholinergic drugs—give extra caution if you take antidepressants, antihistamines, or certain Parkinson’s medicines. Also, trospium can work against cholinesterase inhibitors used for Alzheimer's, so speak up if you use dementia drugs.
Take trospium on an empty stomach for best effect. If you miss a dose, skip it and take the next scheduled dose—do not double up. For older adults, start low and monitor for confusion or balance problems. Drink water to ease dry mouth and eat fiber to prevent constipation.
Most people notice fewer urges or leaks within 2 to 4 weeks; full benefit can take up to 8 weeks. If you see no improvement after 12 weeks, talk with your prescriber about changing dose or switching to another treatment such as mirabegron or pelvic floor therapy.
Trospium isn't well studied in pregnancy. If you're pregnant, planning pregnancy, or breastfeeding, check with your doctor before starting trospium. Your provider may suggest a different option.
Trospium can cause drowsiness or dizziness. Avoid driving or heavy machines until you know how it affects you. Your doctor may check your kidney function before and during treatment regularly.
Want to buy trospium online? Only buy with a valid prescription. Look for pharmacies with clear licensing, pharmacist contact details, secure checkout, and strong customer reviews. If an online store sells prescription drugs without asking for a prescription, don’t trust it.

In one of my recent blog posts, I discussed a common side effect of Trospium, which is constipation. Many people who take this medication for bladder control issues can experience this unpleasant side effect. In order to manage it, I suggested increasing fiber intake, staying hydrated, and incorporating regular exercise into your daily routine. Additionally, over-the-counter stool softeners or laxatives can be used if needed. It's important to talk to your doctor if constipation persists or worsens, as they may recommend adjusting the Trospium dosage or trying a different medication.
