Myrbetriq (mirabegron) is an oral beta-3 agonist medication intended for patients with overactive bladder. Its uses include treatment of urinary urgency, incontinence, or frequency. It increases bladder capacity by activating the beta-3 adrenergic receptor, thus, relaxing the smooth muscle component of the urinary bladder during the storage phase of the bladder cycle.
Take Myrbetriq as prescribed by your physician. It is available in a 25mg and a 50mg extended-release tablet. This tablet should be swallowed whole – avoid crushing, breaking, or chewing. For adults, Myrbetriq may be taken with or without food. For children, it is best to take this medication with food.
Patients may see improvement within 4-8 weeks of taking Myrbetriq. During the course of treatment, make sure to take it every day, as prescribed. Don’t just take it when you deemed it necessary or only when symptoms arise. If you miss a dose of Myrbetriq, take it immediately, provided it is less than 12 hours from your medication schedule. If it has been more than 12 hours, skip that dose and take the next dose as scheduled.
Common side effects include:
-hypertension (high blood pressure)
-dysuria (painful or difficult urination)
-lower back pain
These side effects are usually experienced when the body is adjusting to the treatment, but they are expected to disappear after a few days. However, patients taking Myrbetriq are advised to call the doctor when experiencing a severe increase in blood pressure or if any of the side effects persist.
Stop using the medication immediately if you have an allergic reaction to the medication, such as shortness of breath, wheezing, swollen face, skin rash, and/or itching.
Before taking this medication, talk to your physician about your medical history, especially urinary problems, kidney problems, liver problems, or hypertension.
Do not use Mybetriq if you have a known allergy to mirabegron or any ingredients this medication has.
Tell your doctor about the other medications you have been taking aside from Myrbetriq. This drug has known interaction with thioridazine, flecainide, propafenone, digoxin, and solifenacin succinate.
As this medication may cause hypertension, you should monitor your blood pressure regularly. More so if you have a history of increased blood pressure.
Limit your alcohol intake as it could worsen the side effects like dizziness and headache. Drinking alcohol while on Myrbetriq medication could also interfere with your alertness.
