Uses For trospium
Trospium is used to treat the symptoms of an overactive bladder, such as a frequent need to urinate or incontinence (loss of bladder control). It helps to relax the muscles in the bladder and reduce the daily episodes of incontinence. Trospium is a urinary antispasmodic agent.
trospium is available only with your doctor's prescription.
Before Using trospium
In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For trospium, the following should be considered:
Tell your doctor if you have ever had any unusual or allergic reaction to trospium or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.
Appropriate studies have not been performed on the relationship of age to the effects of trospium in the pediatric population. Safety and efficacy have not been established.
Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of trospium in the elderly. However, elderly patients are more likely to have some unwanted effects (eg, constipation, dry mouth, indigestion, stomach pain, or trouble passing urine) which may require an adjustment in the dose for patients receiving trospium.

Proper Use of trospium
Take trospium only as directed by your doctor. Do not take more of it, do not take it more often, and do not take it for a longer time than your doctor ordered. To do so may increase the chance of side effects.
trospium comes with a patient information insert. It is very important that you read and understand this information. Be sure to ask your doctor about anything you do not understand.
It is best to take trospium with water on an empty stomach, or at least one hour before a meal.
Swallow the extended-release capsule whole with water. Do not open, crush, or chew it.
If you take the extended-release capsule, do not drink alcohol in the first 2 hours after taking the capsule. Alcohol may increase your risk of having drowsiness.
The dose of trospium will be different for different patients. Follow your doctor's orders or the directions on the label. The following information includes only the average doses of trospium. If your dose is different, do not change it unless your doctor tells you to do so.
The amount of medicine that you take depends on the strength of the medicine. Also, the number of doses you take each day, the time allowed between doses, and the length of time you take the medicine depend on the medical problem for which you are using the medicine.

Precautions While Using trospium
It is very important that your doctor check your progress at regular visits to make sure trospium is working properly and to check for unwanted effects.
trospium may cause a serious type of allergic reaction called angioedema. Angioedema may be life-threatening and requires immediate medical attention. Stop taking trospium and check with your doctor right away if you have a rash, itching, a large, hive-like swelling on the face, eyelids, lips, tongue, throat, hands, legs, feet, or sex organs, trouble breathing, or chest tightness while you are using trospium.
trospium, especially in high doses, may cause some people to become dizzy, drowsy, confused, or have blurred vision. Make sure you know how you react to trospium before you drive, use machines, or do anything else that could be dangerous if you are dizzy, not alert, or not able to see well. Drinking alcohol with trospium may increase your risk of having drowsiness.
trospium may make you sweat less, causing your body temperature to increase. Use extra care not to become overheated during exercise or hot weather while you are taking trospium, since overheating may result in heat stroke.
trospium may cause a dry mouth, nose, and throat. For temporary relief of mouth dryness, use sugarless candy or gum, melt bits of ice in your mouth, or use a saliva substitute. If your mouth continues to feel dry for more than 2 weeks, check with your medical doctor or dentist. Continuing dryness of the mouth may increase the chance of dental disease, including tooth decay, gum disease, and fungus infections.
Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal or vitamin supplements.
