Detrol is a brand name for the medication tolterodine. Tolterodine belongs to a class of medications called antimuscarinics or anticholinergics. It is primarily used to treat overactive bladder (OAB) symptoms, such as frequent urination, urgency, and urge incontinence.

Active Ingredient: Tolterodine

Detrol tablets



Form: Tablet

Type: Generic

Detrol works by blocking certain receptors in the bladder, reducing muscle contractions and helping to control the release of urine. This can improve bladder control and reduce the symptoms associated with OAB.

Medicine is available in tablet form and extended-release capsules. The dosage and treatment duration may vary depending on the individual and the severity of the condition.

It is important to note that Tolterodine is not a cure for OAB but helps manage the symptoms. The medication needs to be taken regularly as directed to maintain its effectiveness.

How to use

To use Detrol effectively and safely, follow these general guidelines:

  1. Follow the prescribed dosage: Take medicine exactly as prescribed. The dosage may vary depending on the severity of your symptoms and your individual response to the medication.
  2. Take with or without food: Tolterodine can be taken with or without food. Swallow the tablet or capsule whole with a glass of water. Do not crush, chew, or break the extended-release capsules, as they are designed to release the medication slowly over time.
  3. Stick to a consistent schedule: Take Detrol at the same time(s) each day to maintain a consistent level of the medication in your system. This helps optimize its effectiveness. If you are taking the extended-release capsules, it is particularly important to take them at the same time each day.
  4. Be patient: It may take several weeks for Detrol to exert its full therapeutic effect. Continue taking the medication as prescribed, even if you do not notice immediate improvements.
  5. Do not stop abruptly: Suddenly stopping the medication may result in a return of your symptoms.


The dosage of Detrol can vary depending on several factors, including the severity of your symptoms, your response to the medication, and any other medical conditions you may have.Here are some general considerations regarding the dosage:

  1. Initial dosage: The usual starting dose for Detrol is 2 mg taken twice daily (4 mg total daily dosage).
  2. Maintenance dosage: In most cases, the maintenance dosage of Detrol is 4 mg per day, taken either as a single dose or divided into two doses of 2 mg each.
  3. Extended-release capsules: If you are prescribed Detrol LA, the extended-release capsules, the typical starting dose is 4 mg once daily. The dosage may be adjusted based on your response to treatment.

  5. Elderly patients: Older adults may require a lower dosage of Detrol due to potential age-related changes in kidney function.

Side effects

Detrol may cause certain side effects in some individuals. While not everyone experiences these side effects, it's important to be aware of them. Common side effects can include:

Missed Doses

If you miss a dose of Detrol, follow these general guidelines:

  1. Take the missed dose as soon as you remember: If you remember within a few hours of the missed dose, take it as soon as possible.
