Bladder or Urinary Obstruction
Use Sanctura cautiously if you have difficulty emptying your bladder or a condition that blocks urine flow.
Because Sanctura relaxes the bladder muscle, it may increase the risk of urinary retention in some people.
Contact your healthcare provider if you are unable to urinate, have severe lower abdominal discomfort, or notice a major change in urine flow.
Gastrointestinal Obstruction
Tell your healthcare provider if you have a condition that slows or blocks movement through the stomach or intestines.
Sanctura has anticholinergic effects and may reduce gastrointestinal movement, which can worsen certain obstructive conditions.
Kidney Problems
Tell your healthcare provider if you have kidney disease.
Trospium is removed mainly through the kidneys, so reduced kidney function can increase the amount of medication in your body and raise the risk of side effects.
People with severe kidney impairment may need a lower dose or less frequent dosing.
Narrow-Angle Glaucoma
Use Sanctura cautiously if you have controlled narrow-angle glaucoma.
Anticholinergic medications can increase pressure inside the eye in susceptible people.
Seek medical attention if you develop sudden eye pain, blurred vision, red eyes, or halos around lights.
Dry Mouth and Constipation
Common side effects of Sanctura include:
- Dry mouth
- Constipation
- Headache
- Blurred vision
These effects are often mild, but contact your healthcare provider if they become severe, persistent, or difficult to manage.
Dizziness and Drowsiness
Sanctura may cause dizziness, drowsiness, or blurred vision.
Use caution when driving, operating machinery, or performing activities that require alertness until you know how Sanctura affects you.
Drug Interactions
Sanctura can interact with other medications, especially those with anticholinergic or antimuscarinic effects.
Tell your healthcare provider about all prescription medications, over-the-counter products, vitamins, supplements, and herbal products you use.
Using several anticholinergic medications together may increase side effects such as dry mouth, constipation, blurred vision, confusion, or urinary retention.
Older Adults
Older adults may be more sensitive to anticholinergic side effects.
Your healthcare provider may monitor for constipation, urinary retention, dizziness, confusion, or other side effects and adjust treatment if needed.
Pediatric Use
The safety and effectiveness of Sanctura have not been established in children.
For this reason, Sanctura is generally not recommended for pediatric use unless a healthcare provider determines that it is appropriate.
Allergic Reactions
Do not take Sanctura if you have had a serious allergic reaction to trospium chloride or any ingredient in the medication.
Seek urgent medical attention if you develop swelling of the face, lips, tongue, or throat, hives, or difficulty breathing.
Take Sanctura Only as Prescribed
Do not increase or decrease your Sanctura dose on your own.
Your healthcare provider may adjust treatment based on kidney function, age, side effects, and how well your overactive bladder symptoms are controlled.
