Myrbetriq is a prescription drug well known for its capacity to improve the lives of people tormented by the unrelenting symptoms of overactive bladder (OAB).

The main goal of Myrbetriq is to relieve the symptoms of OAB, a disorder marked by an unexpected and intense need to urinate. By attacking OAB symptoms head-on, this ground-breaking drug aims to empower the victims.

Myrbetriq contains Mirabegron as its active component. Mirabegron adopts a distinct strategy from conventional OAB treatments, which mostly rely on anticholinergic drugs. Being a member of the beta-3 adrenergic agonist medication class, Mirabegron operates by focusing on receptors in the bladder’s detrusor muscle.

For people who might not have experienced relief from other medications, Myrbetriq offers a beneficial alternative thanks to its specific mode of action compared to conventional OAB treatments. It promises to help people with OAB regain control over their bladder function, lessen urgencies, and eventually improve their quality of life.

How Myrbetriq performs its transformational magic through two steps:

  1. Muscle Relaxation: Mirabegron, the main component, binds to beta-3 adrenergic receptors in the detrusor muscle of the bladder. The muscle cells receive a signal when Mirabegron binds to the receptors. The detrusor muscle begins to relax as a result of this signal. The distinctive urgency and incontinence of OAB are brought on by the detrusor muscle’s tendency to contract too frequently and intensely. Mirabegron plays a significant role in reducing this over-activity, preventing signs of OAB.
  2. Increased Bladder Capacity: The bladder can hold more pee as the detrusor muscle relaxes. As a result, there will be fewer unplanned trips to the bathroom and less frequent urgent cravings to urinate.

Precautions and Warnings

Myrbetriq (mirabegron) is an effective medication for treating the symptoms of overactive bladder (OAB), but like any prescription medication, it has specific side effects. To guarantee safe and effective use, awareness of these side effects is crucial. Using Myrbetriq carries the following significant warning and precautions:


People with the conditions below need to be cautious when taking Myrbetriq. To be safe, talk with your doctor about your health to find the right prescriptions and alternatives for your requirements.

Allergies and Sensitivities

Allergic reactions might range from mild to severe. So, alert your doctor about any allergies or sensitivities you may have before taking Myrbetriq, especially if you have ever experienced an adverse reaction to Mirabegron or any other medicine.

Existing Medical Conditions

Share the complete medical history details with your healthcare practitioner, including any existing medical issues. Uncontrolled high blood pressure, liver, renal, and other medical diseases that may influence your ability to use Myrbetriq safely should be considered.

Pregnancy and Breastfeeding

Let your healthcare practitioner know if you are or plan to be pregnant or nursing. Myrbetriq’s safety during pregnancy and breastfeeding has not been well looked into, so your doctor will assess the potential advantages and disadvantages before prescribing it.


Myrbetriq might cause some severe effects if not used correctly. Be sure to check out for some of these side effects and warnings when using Myrbetriq:

Blood Pressure

The drug Myrbetriq may cause a rise in blood pressure. Throughout treatment, regular blood pressure checking is essential. If you have a history of high blood pressure or cardiovascular problems, your doctor will carefully evaluate if Myrbetriq is appropriate.

Severe Liver or Kidney Impairment

If you have severe liver or kidney damage, you should use Myrbetriq with caution, or better yet, avoid it altogether. Slow removal of the drug from your body due to these conditions could increase the risk of side effects of Myrbetriq. Before beginning Myrbetriq, discussing liver or renal issues with your doctor is crucial.

Avoid Abrupt Discontinuation

Avoid stopping Myrbetriq abruptly without first consulting your doctor. The symptoms of OAB may worsen with abrupt withdrawal. Talk to your healthcare practitioner if you want to stop taking Myrbetriq or change to a different medication. Your Doctor will let you know how to do so safely.

You should fully understand and adhere to these warnings and precautions to use Myrbetriq safely and effectively. Please always follow your doctor’s advice and quickly note any unexpected or severe side effects.

Side Effects

Although Myrbetriq (mirabegron) is typically well tolerated, some people may experience side effects like any medicine. The following are some of the frequent side effects of Myrbetriq:

  • Blood Pressure Elevation: Myrbetriq may cause blood pressure to rise. During treatment, it is crucial to regularly monitor your blood pressure, especially if you have a history of hypertension.
  • Headache: While a reasonably frequent side effect, headaches are often mild to moderate in strength.
  • Constipation: Some people who take Myrbetriq could become constipated. Keeping hydrated and eating a fiber-rich, well-balanced diet can help control this adverse effect.
  • Dry Mouth: Xerostomia, often known as dry mouth, might occur in some users. Keeping hydrated and using sugar-free gum or lozenges can help.
  • Urinary Tract Infection: Urinary tract infections (UTIs) can happen less frequently. Seek medical help if you develop symptoms like fever, frequent urination, or pain while urinating.

Drug Interactions

Some drugs may interact with Myrbetriq (Mirabegron), perhaps reducing its efficacy or raising the possibility of adverse side effects. To ensure safe and successful treatment, let your healthcare practitioner know about all the prescription, over-the-counter medication, and dietary supplements you use.

Here’s a list of meaningful Myrbetriq medication interactions you need to note:

  • Monoamine Oxidase Inhibitors (MAOIs): It is typically not advised to take Myrbetriq or MAOIs within two weeks of stopping them. Combining these drugs increases the chance of developing high blood pressure.
  • Digoxin: Myrbetriq can potentially raise the body’s levels of digoxin. If you are taking both drugs, your healthcare provider may need to modify your digoxin dosage and constantly watch your digoxin levels.
  • Ketoconazole: The antifungal drug ketoconazole can raise the body’s levels of Myrbetriq. Due to this interaction, the dosage may need to be changed, or the side effects may need to be closely monitored.
  • Rifampin: The antibiotic Rifampin may lower the body’s levels of Myrbetriq, potentially lowering its effectiveness. If you are taking Rifampin in addition to Myrbetriq, your doctor may need to change your dosage.

 Strengths and Dosages

Myrbetriq (mirabegron) has various strengths that offer dosage flexibility, enabling healthcare professionals to customize treatment to each patient’s needs.

Your healthcare professional bases the dosage strength choice on your unique condition, medical history, and medication response. To achieve the best results in treating overactive bladder, it’s imperative that you closely adhere to your healthcare provider’s recommendations and the recommended dosage schedule.

Your doctor may start you on the lesser dose of 25 mg and then change it as necessary based on how you respond specifically. Only change your Myrbetriq dosage after talking to your doctor first, and always take it as directed.

The medication Myrbetriq has two main strengths:

  • Myrbetriq 25 mg: This consists of a 25 milligrams of mirabegron per tablet. It is mainly administered to patients who could be more sensitive to medication or have particular health concerns and is frequently given as an initial dose.
  • Myrbetriq 50 mg: Each pill of this stronger medication version includes 50 milligrams of mirabegron. This level is frequently recommended when the lower dose is proven ineffective or when a more robust reaction is required to treat the symptoms of an overactive bladder.


While this quick guide provides ways to use Myrbetriq effectively, you should follow the directions on your prescription label and take Myrbetriq as directed.

  • Oral Administration: At the same time every day, swallow the tablet whole, with or without food.
  • Do not crush pills: Myrbetriq pills should not be chewed, crushed, split, or broken.
  • Keep Hydrated: Drink adequate water to keep your bladder healthy and avoid constipation.
  • Be Consistent: The key is consistency, so do not skip doses and follow your treatment plan.
  • Report Adverse Effects: Report any unusual or severe adverse effects to your healthcare professional.
  • Regular Monitoring: Be receptive to periodic evaluations of your performance.
  • Open Communication: Share your worries or inquiries with your healthcare professional to receive individualized advice.
