before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. these factors may affect how you should use this medication.
drowsiness/blurred vision: trospium may cause drowsiness or blurred vision. avoid activities requiring mental alertness, such as driving, operating machinery, or performing hazardous work, until you know how trospium affects you. alcohol and other medications that cause drowsiness may increase the drowsiness caused by trospium.
gastrointestinal disorders: trospium may slow down the passage of food through the digestive system. if you have an obstructive gastrointestinal disorder, ulcerative colitis, intestinal atony, or myasthenia gravis, your condition should be monitored closely by your doctor while you are taking this medication as trospium may worsen these conditions.
heat stroke: when trospium is taken in a hot environment, it can cause fever and heat stroke due to decreased sweating. be sure to drink enough water if you are in a hot environment for a prolonged period of time.
kidney function: decreased kidney function may cause trospium to build up in the body, causing side effects. if you have kidney disease or decreased kidney function, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
liver function: if you have moderate liver function impairment, your condition should be monitored closely by your doctor while you are taking trospium. the safety and effectiveness of using trospium for people with severe liver function impairment have not been established.
medical conditions: the safety and effectiveness of trospium have not been established for people with congestive heart failure, low blood potassium levels, heart attack, or other conditions associated with an increased risk of abnormal heart rhythms.
narrow-angle glaucoma: if you are being treated for narrow-angle glaucoma, you should use trospium only if the benefits outweigh the risks. talk to your doctor about the risks and benefits of using this medication. report any changes in vision to your doctor as soon as possible while you are taking this medication.
pregnancy: this medication should not be used during pregnancy unless the benefits outweigh the risks. if you become pregnant while taking this medication, contact your doctor immediately.
