Common Side Effects of Terlivaz
Terlivaz, also known as tolterodine extended-release, is an antimuscarinic medication used to treat the symptoms of overactive bladder, such as incontinence and frequent urination [1]. While generally well-tolerated, Terlivaz can cause a range of side effects, some of which may be serious.
Dry Mouth: A Common Complaint
Dry mouth (xerostomia) is the most common side effect of Terlivaz, affecting up to 30% of patients [2]. This occurs due to the drug's antimuscarinic action, which reduces saliva production. Other oral side effects include taste changes and oral thrush.
Constipation: A Possible Concern
Constipation, or difficulties with bowel movements, is another common side effect, especially in older adults [3]. This may be due to the drug's effect on gut motility.
Headaches and Dizziness
Headaches and dizziness can occur in some individuals, but these side effects are generally mild and temporary.
Less Common but Serious Side Effects
In rare cases, Terlivaz can cause more serious side effects, such as:
* Allergic reactions, which may present as hives, itching, or difficulty breathing
* Abnormal heart rhythms, such as QT prolongation [4]
* Increased heart rate
* Seizures (in rare cases)
Precautions and Considerations
Before taking Terlivaz, it's essential to discuss your medical history with your doctor, especially if you have:
* A history of heart conditions
* An irregular heartbeat
* Kidney problems
* Liver disease
* Urinary retention or narrow-angle glaucoma
Your doctor may need to adjust your dosage or monitor you more closely if you have any of these conditions [5].
