You’re probably wondering what Myrbetriq is used for. Well, if you’re dealing with urinary incontinence or overactive bladder, Myrbetriq might be a term you’ve come across. It’s a medication designed to help manage these conditions effectively.

What is Myrbetriq?

Myrbetriq, known generically as mirabegron, is a prescription medication primarily used to treat symptoms of overactive bladder, such as frequent urination, urgent need to urinate, and urinary incontinence. It belongs to a class of drugs called beta-3 adrenergic agonists, which work by relaxing the bladder muscles, thus reducing symptoms.

Forms and Strengths

Myrbetriq is available in tablet form and comes in two strengths: 25 mg and 50 mg. These tablets are taken orally with water, usually once daily. The choice of strength depends on your healthcare provider’s recommendation, which is based on factors such as the severity of your condition and your response to the medication.

How to Take Myrbetriq

Taking Myrbetriq is simple and convenient. Here’s a step-by-step guide on how to take it effectively:

  1. Follow Your Prescription: Always adhere to your healthcare provider’s prescription instructions carefully. Do not take more or less of the medication than prescribed.
  2. Choose Your Time: You can take Myrbetriq with or without food. Pick a time that fits into your daily routine and stick to it consistently.
  3. Swallow Whole: Swallow the tablet whole with a full glass of water. Do not crush, chew, or break the tablet before swallowing.
  4. Stay Consistent: To maximize the benefits of Myrbetriq, take it at the same time each day. This helps maintain a steady level of the medication in your body.
  5. Monitor Your Progress: Keep track of your symptoms and any changes you experience while taking Myrbetriq. This information can be valuable for your healthcare provider to assess the effectiveness of the treatment.

Myrbetriq 25 mg vs. Myrbetriq 50 mg

You might wonder about the difference between the two strengths of Myrbetriq. Essentially, the 25 mg and 50 mg tablets contain different amounts of the active ingredient, mirabegron. Your healthcare provider will determine the appropriate strength for you based on factors such as your medical history, the severity of your symptoms, and your response to the medication.

How Long Does it Take for Myrbetriq to Work?

Patience is key when starting Myrbetriq. While some individuals may experience improvements in symptoms within a few weeks of starting the medication, it may take up to several months for the full benefits to be realized. Consistent, daily use is crucial for optimal results.

Who Should Not Take Myrbetriq?

While Myrbetriq is generally well-tolerated by most people, there are certain individuals who should avoid taking it. You should not take Myrbetriq if:

  • You have severe liver or kidney problems.
  • You have uncontrolled high blood pressure.
  • You are allergic to mirabegron or any other ingredients in Myrbetriq.

Always inform your healthcare provider about your medical history, including any existing conditions or allergies, before starting Myrbetriq.

Myrbetriq Cost and Availability of Generic

As for cost, Myrbetriq can be expensive, especially if you’re paying out of pocket or if it’s not covered by your insurance. However, there is a generic version of mirabegron available, which may offer a more affordable alternative. Be sure to ask your pharmacist about generic options and potential cost savings.


Myrbetriq can be a valuable tool in managing symptoms of overactive bladder and urinary incontinence. By understanding its dosage, strengths, and how to take it, you can use this medication effectively to improve your quality of life.
