When addressing overactive bladder (OAB) symptoms like frequent urination and urgency, Myrbetriq (mirabegron) can be a significant help. However, being aware of the potential side effects is crucial when using this medication.
What is Myrbetriq?
Myrbetriq, known generically as mirabegron, is used to treat overactive bladder (OAB) symptoms. Classified under beta-3 adrenergic agonists, it functions by relaxing the bladder muscles, decreasing both urgency and frequency of urination, and reducing urinary incontinence episodes in OAB patients.
Unlike many OAB medications that usually target nerve signals, Myrbetriq specifically acts on the beta-3 receptors in bladder muscles. This targeted action helps in increasing bladder capacity and reducing sudden, involuntary contractions typical of OAB.
Myrbetriq is usually taken orally once daily, with or without food, as directed by a healthcare provider. Following the prescribed dosage and instructions closely is essential for achieving optimal results and minimizing side effects.
Myrbetriq Side Effects
| Common Side Effects | Serious Side Effects |
| Headaches | Allergic Reactions |
| Increased Blood Pressure | Cardiovascular Effects |
| Urinary Tract Infections (UTIs) | Liver Damage |
| Nausea | Vision Changes |
Common Side Effects
When starting Myrbetriq, common side effects may occur but are generally mild. These can include headaches, slightly elevated blood pressure, urinary tract infections (UTIs), and nausea. These effects often subside as your body becomes accustomed to the medication.
- Headaches – Headaches are a frequently reported side effect among Myrbetriq users. They can range from mild to severe and may be more prevalent during the early stages of treatment.
- Increased Blood Pressure – Some individuals may notice a slight increase in blood pressure. Regular blood pressure monitoring is essential, especially for those with a history of hypertension.
- Urinary Tract Infections (UTIs) – UTIs, marked by painful urination, frequent urination, and lower abdominal discomfort, may develop in some users.
- Nausea – Nausea is another common side effect, particularly at the beginning of treatment, but it often decreases over time.
Serious Side Effects
In rare instances, Myrbetriq can lead to severe side effects requiring immediate medical attention:
- Allergic Reactions – Although infrequent, allergic reactions to Myrbetriq can occur, presenting symptoms like rash, itching, swelling, dizziness, or difficulty breathing. Immediate medical assistance is necessary if these symptoms appear.
- Cardiovascular Effects – Myrbetriq may influence heart rhythm, potentially causing palpitations or an irregular heartbeat. Those with existing heart conditions should use Myrbetriq with caution and under close medical supervision.
- Liver Damage – Though rare, Myrbetriq has been associated with liver problems like elevated liver enzymes and liver damage. Signs include jaundice (yellowing of the skin or eyes), dark urine, and chronic fatigue.
Myrbetriq Side Effects in the Elderly
The elderly may be more susceptible to certain side effects of Myrbetriq due to age-related metabolic and organ function changes. Possible side effects include constipation, UTIs, dry mouth, increased blood pressure, and dizziness, which could increase the risk of falls due to reduced coordination.
Why is Myrbetriq So Expensive?
Myrbetriq’s high price can be traced to multiple factors. First, the extensive research and development costs borne by pharmaceutical firms for new drug creation contribute to its pricing. Patent protection also permits the manufacturer exclusive sale rights for a specified period, enabling higher prices in the absence of generic competition.
Additionally, the intricate manufacturing processes, coupled with the expenses tied to clinical trials, regulatory approvals, and marketing, lead to elevated costs. Furthermore, limited competition in the OAB medication market can keep prices high.
Myrbetriq Alternatives
If Myrbetriq (mirabegron) isn’t a suitable option for you or if you prefer different treatment methods, several alternatives can efficiently manage overactive bladder symptoms:
- Anticholinergic Medications: These medications block signals responsible for bladder muscle contractions. Examples include oxybutynin (Ditropan), tolterodine (Detrol), solifenacin (Vesicare), and darifenacin (Enablex).
- Beta-3 Adrenergic Agonists: Other medications targeting the beta-3 receptors in the bladder may have different side effects from Myrbetriq. An example is vibegron.
- Behavioral Therapies: Techniques like bladder training, pelvic floor exercises (Kegel exercises), and biofeedback can assist in improving bladder control and reducing urgency and frequency.
- Topical Estrogen Therapy: This approach can help reinforce urinary tract tissues in postmenopausal women, enhancing OAB symptoms.
- Botulinum Toxin Injections: Botox injections into the bladder muscle can minimize urgency and frequency by relaxing the bladder, particularly when other treatments have been ineffective.
Takeaways
As you navigate OAB treatment with Myrbetriq, it is essential to stay informed about the medication and its possible side effects. This knowledge empowers you to manage your health effectively.
If you experience any concerning symptoms, whether common or severe, make sure to consult your healthcare provider. Ensuring that your treatment plan aligns with your needs and well-being is fundamental to effective management.
