For Urinary Incontinence "So my doctor said that there were no known side effects from taking Myrbetriq. Well, I find that to be rubbish. I have taken this Myrbetriq and now I can't pee at all. Hardly anything is coming out, and I wake up with a fast heart rate and cramps. I am 25, and this whole peeing thing sucks! I hope you all get well soon."

For Urinary Frequency "Took 25 mg of Myrbetriq samples, then bought another month's supply of the drug. I took it for a total of 40 days. It initially helped with my urinary frequency, but then I started experiencing headaches during the afternoon and evening. I slept well for the first few days, but then the headaches became constant. They were the worst headaches I have ever felt, with intense, constant stabbing pain. I felt lethargic, lost my appetite, and only found minimal relief with ice on my head. I had several sleepless nights and then developed a fast heartbeat with pounding in my ears. I often experienced the sensation of vomit rising in my throat and became completely immobile. I stopped taking Myrbetriq on September 12th, 2019. Four days later, I am still dealing with the headache, but now it's intermittent with sudden sparks or flashes of pain in my head. Today, I managed to eat oatmeal and scrambled eggs for the first time. While I'm glad this drug has helped some people, I would recommend caution before using it."

For Urinary Incontinence "I have been feeling very bad for the last 3 weeks. I even went to the ER. I have had high BP, constant headache, shortness of breath, chest pains, rapid heartbeat, and buzzing in my ears. It has not helped my bladder issues. Worst of all, none of the doctors I have seen figured that out. Even after asking what all my medications are. When they kept telling me all was well, except for mildly high BP. So, each time I left feeling like I was going crazy or a hypochondriac. Then I started thinking, what drug have I started taking most recently. I looked it up and surprise... there were all my symptoms. Well, I have stopped taking this drug and will not recommend it to anyone..."

For Urinary Incontinence "For two or three days, this drug Myrbetriq seemed to help my urinary urgency issues. But it quickly raised my blood pressure and caused heart-pounding problems. Then my hair started to fall out. I went online and read of many people losing their hair from this drug, so I stopped it immediately. I am so glad I had been given a 30-day sample supply. It is so expensive, and it is not worth the side effects."

For Urinary Frequency "Horrible! I took one 25 mg pill 30 hours ago, and my heart has been racing ever since. I feel like I'm on crack and can't sleep at all. This is the most miserable feeling. I called the pharmacist, and she said that Myrbetriq has a 50-hour half-life, which means that it's still another 20 hours before even half of the drug will be out of my system. On the flip side, I've had no overactive bladder whatsoever since I took it. As soon as I recover from this fiasco, I'm going back to the Oxytrol Patch."

For Urinary Frequency "I have been on Myrbetriq and Vesicare for about nine months. I had dry mouth and some heart racing, but didn't connect it to the medication. My migraines also occurred with more frequency, but again I didn't connect it to the medication until I read the entries on this site. Last week, all of a sudden, the drugs stopped working, and I became unable to control my bladder. I have to take Pyridium every eight hours, or I am in pain like I have a UTI, but my urine culture is clear. My doctor is scheduling me for Botox injections via cystoscopy. I hope it works because I can barely leave the house."

For Urinary Frequency "I took this for 2 months. I felt terrible all the time. So tired I could barely motivate, and my heart raced out of my body. Told my doctor and have since stopped taking it. Went back to what I was taking for years with no problem."

For Urinary Frequency "I took this medicine for 2 weeks. The side effects are horrible. They started with very dry mouth and sinus, as I continued the drug, I developed blurry vision, headaches, joint pain that also caused weakness in my hands, chest pain, heart racing, diarrhea, upset stomach, and my hair fell out by the handful. I have been off the med for 3 days now and still feel awful."

For Urinary Frequency "Myrbetriq 25 mg for my interstitial cystitis made my symptoms worse. I started on a Friday, had some mild side effects such as dizziness, stomach pain, heartburn, racing heart, and headache. They increased in intensity, I was physically exhausted for no reason, and I was peeing close to 50 times a day, more than double. I contacted my Dr. and left a message, but stupidly continued taking the meds for 3 more days, thinking side effects would go away. They got worse. At that point, the bladder pain and pain when peeing was so excruciating, I thought I was going to die. I took AZO Bladder Pain Relief, which helped with the pain since my Dr. never called back. A week later, I'm back to where I started with my IC, and my Dr. has still not called."

For Urinary Frequency "Having bladder pain after UTI. Took one 50 mg one night at 8 pm. Could never get sleepy. Finally went to sleep at 1 am and woke with a rapid heartbeat and anxiety at 3 am. Was awake all day and still had trouble sleeping the next night without taking another dose. So awoke at 5:30 am the next morning with a pulse at 116. My ears have been buzzing and ringing, which impairs my hearing. I would not recommend this medicine, for it causes high BP, fast heart rate, ears buzzing, anxiety. I could tell my urologist had trouble believing me, for he had told me it had no side effects. Why would he say that when you read on the label, all I had are listed? Well, he can say I told him about mine. I don’t like this drug. Oxybutynin was better even with the dry mouth."

For Neurogenic Detrusor Overactivity "I was diagnosed with bladder spasms. Dr. gave me a month's supply of Myrbetriq, and at first, it was awesome, but then the side effects kicked in: my heart racing and headaches, eye pain, blurry vision. Driving home the other night, I had blurry vision, and I felt lightheaded. I was thinking I might have had a stroke. I'm never taking it again. I just wonder how long it takes to get out of my system. My anxiety is off the chart - it is just not worth it."

For Urinary Frequency "Complete waste of money. Causes headaches, insomnia, heart racing. More, this drug should be taken off the market."
