What does Myrbetriq do, and is it an anticholinergic?
Myrbetriq is not an anticholinergic. It contains mirabegron, which works differently from classic overactive bladder anticholinergics (such as oxybutynin or tolterodine). Myrbetriq is a beta-3 adrenergic agonist that helps relax the bladder muscle to reduce urgency and frequency.
Why do people think Myrbetriq is an anticholinergic?
Some bladder medications are commonly grouped together as “overactive bladder pills,” and all are used for similar symptoms (urgency, frequent urination). But the drug class matters: Myrbetriq uses beta-3 adrenergic receptor activity, not anticholinergic (muscarinic) receptor blocking.
What side effects are more typical for Myrbetriq vs. anticholinergics?
Because it is not an anticholinergic, Myrbetriq is less associated with anticholinergic-type effects such as dry mouth, constipation, and cognitive side effects that are commonly reported with muscarinic blockers. Side effects reported with Myrbetriq can include things like increased blood pressure and other beta-3 related effects.
Can Myrbetriq be used with anticholinergics?
Yes. In some treatment plans, clinicians combine a beta-3 agonist like mirabegron (Myrbetriq) with an anticholinergic to improve symptom control when one agent alone is not enough. This is a prescribing decision based on tolerability and patient-specific risks.
