Administer with caution to patients with clinically significant bladder outflow obstruction or gastrointestinal obstructive disorders due to risk of urinary or gastric retention; use with caution in patients with conditions such as ulcerative colitis, intestinal atony, and myasthenia gravis
To administer, must carefully monitor patients with controlled narrow-angle glaucoma; benefits should outweigh risks
Somnolence reported; advise patients not to drive or operate heavy machinery until they know how therapy affects them
Drug substantially excreted by kidney; effects of moderate renal impairment on systemic exposure are not known but systemic exposure is likely increased; risk of anticholinergic adverse reactions (including dry mouth, constipation, dyspepsia, urinary tract infection, and urinary retention) is expected to be greater in patients with moderate renal impairment
Pregnancy & Lactation
Pregnancy Category: C
Lactation: Excretion in mikl unknown; use with caution
Pregnancy Categories
A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.
B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk. C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done. D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk. X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist. NA: Information not available.Pharmacology

TROSPIUM EXTENDED-RELEASE - ORAL
(TROW-spee-um)
COMMON BRAND NAME(S): Sanctura XR
USES: This medication is used to treat an overactive bladder. By relaxing the muscles in the bladder, trospium improves your ability to control your urination. It helps to reduce leaking of urine, feelings of needing to urinate right away, and frequent trips to the bathroom. Trospium belongs to a class of drugs known as antispasmodics. It is also known as an antimuscarinic.
HOW TO USE: Read the Patient Information Leaflet provided by your pharmacist before you start using trospium and each time you get a refill. If you have any questions, consult your doctor or pharmacist.Take this medication by mouth on an empty stomach at least 1 hour before a meal, usually once daily or as directed by your doctor.Swallow the capsule whole. Do not crush or chew the capsule. Also avoid drinking alcohol or taking any product containing alcohol for 2 hours before and after taking this medication. Alcohol can destroy the long action of the drug and may increase side effects.If you cannot swallow the capsule, you may open the capsule and place the beads in a small amount of water or directly onto the tongue. Do not crush or chew the beads because doing so may cause the drug to be released too quickly, increasing side effects. Swallow all of the beads right away.Use this medication regularly to get the most benefit from it. To help you remember, take it at the same time each day. Dosage is based on your medical condition and response to treatment.Tell your doctor if your condition does not improve or if it worsens.
SIDE EFFECTS: Dry mouth, constipation, stomach upset, dry eyes, dry nose, dizziness, blurred vision, or drowsiness may occur. If any of these effects last or get worse, tell your doctor or pharmacist promptly.Remember that this medication has been prescribed because your doctor has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.Tell your doctor right away if you have any serious side effects, including: eye pain, difficulty urinating, fast heartbeat, mental/mood changes (such as hallucinations, confusion).A very serious allergic reaction to this drug is rare. However, get medical help right away if you notice any symptoms of a serious allergic reaction, including: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.This is not a complete list of possible side effects.

To view formulary information first create a list of plans. Your list will be saved and can be edited at any time.
Adding plans allows you to:
- View the formulary and any restrictions for each plan.
- Manage and view all your plans together – even plans in different states.
- Compare formulary status to other drugs in the same class.
- Access your plan list on any device – mobile or desktop.
