Dezrol La 4 mg Capsule ER

Dezrol La 4 mg Capsule ER is an extended-release capsule that contains 4 mg of tolterodine in each capsule. It belongs to a class of medicines called antimuscarinics, which help calm an overactive bladder. It is used to reduce urinary urgency, frequent urination, and urge incontinence. Dezrol La 4 mg Capsule ER is designed for adults whose doctor has decided a 4 mg daily strength is appropriate.

How it works: Tolterodine relaxes the bladder muscle by blocking signals that trigger sudden bladder contractions. In Dezrol La 4 mg Capsule ER, the extended-release capsule gives the medicine gradually through the day to help control symptoms.

Dezrol La 4 mg Capsule ER is the higher-strength sibling of Dezrol La 2 mg Capsule ER, so it is not the usual starting option for everyone. Doctors may choose Dezrol La 4 mg Capsule ER when a patient needs once-daily, extended-release treatment and has already been assessed as suitable for the higher strength. Because it is extended-release, it is meant to release tolterodine gradually rather than all at once.

• Overactive bladder
• Urinary urgency
• Frequent urination
• Urge urinary incontinence
• Bladder spasms related to overactivity

• Swallow Dezrol La 4 mg Capsule ER whole with water.
• Do not crush, chew, or open the capsule, because that can affect the extended-release action.
• Take it exactly once daily only if your prescriber told you to use the 4 mg strength.
• You may take it with or without food.
• Try to take it at the same time each day for steady symptom control.

Each Dezrol La 4 mg Capsule ER provides 4 mg of tolterodine in an extended-release capsule. The usual dose for this strength is 4 mg once daily, and the maximum recommended daily dose is typically 4 mg when using the extended-release form. Your doctor decides whether this strength is right for you based on your symptoms, kidney or liver function, and other medicines you take.

Do not change your dose or stop the medicine without speaking to your doctor.

Common side effects of Tolterodine may include:

• Dry mouth, which may be more noticeable with the 4 mg strength
• Headache
• Constipation
• Dizziness
• Blurred vision
• Stomach upset
• Dry eyes

• Dezrol La 4 mg Capsule ER is a higher-strength option and should only be used if your doctor has assessed that 4 mg is appropriate for you.
• Use caution if you have narrow-angle glaucoma, urinary retention, stomach-emptying problems, or severe constipation.
• Tell your doctor if you have liver or kidney disease, because the dose or choice of medicine may need to change.
• This medicine can cause dizziness or blurred vision, so be careful driving or operating machinery until you know how it affects you.
• Alcohol may worsen dizziness or dryness in some people.
• Report palpitations, fainting, or chest symptoms promptly, especially if you have heart disease.
• Do not use it without medical advice if you are pregnant, breastfeeding, or planning pregnancy.

• Other anticholinergic medicines, which can increase dry mouth, constipation, and urinary retention
• Strong CYP3A4 inhibitors such as ketoconazole or itraconazole, which can raise tolterodine levels
• Some antibiotics and antivirals that affect liver enzymes, which may change exposure to tolterodine
• Medicines that can cause drowsiness, dizziness, or blurred vision, which may add to side effects
