Myrbetriq vs. Flomax

Head-to-head comparisons of medication uses, side effects, warnings, and more.

Key takeaways

Myrbetriq (mirabegron) and tamsulosin (Flomax) are both prescription medications, but they treat different conditions. Myrbetriq is used to manage overactive bladder (OAB) in adults and neurogenic detrusor overactivity (NDO) in children. It works by relaxing the bladder muscles to hold more urine, and it is taken once daily. On the other hand, Tamsulosin is used to treat benign prostatic hyperplasia (BPH), or an enlarged prostate, in men. It works by relaxing the muscles in the prostate and bladder to make urination easier and is taken 30 minutes after the same meal each day. Myrbetriq does not have a generic version available, while tamsulosin does. Common side effects of Myrbetriq include high blood pressure and urinary tract infections, whereas tamsulosin can cause headaches, dizziness, and abnormal ejaculation. Additionally, Myrbetriq is not recommended for people with severe kidney or liver problems, while tamsulosin should be used cautiously in those with a sulfa allergy.
