Dosage considerations

Below are some things to consider about Myrbetriq’s dosage.

Missing a dose: If you miss a dose of Myrbetriq, take your missed dose as soon as you remember. But if it’s been more than 12 hours since you missed the dose, just skip it.

You can take your next dose again at its usual time. If you aren’t sure whether to take a missed dose or skip it, ask your doctor or pharmacist.

It’s important that you don’t take any extra doses of Myrbetriq to make up for a missed dose. Doing this can increase your risk of side effects with the drug. (For information about the drug’s side effects, see the “Myrbetriq: Side effects” section above.)

View these medication reminder options to help avoid missing doses. You could also set an alarm, use a timer, or download a reminder app on your phone.

Length of treatment: Doctors typically prescribe Myrbetriq as a long-term treatment. You’ll likely take it long term if you and your doctor feel it’s safe and effective for your condition.

Questions you may have about Myrbetriq

Here are some common questions about Myrbetriq and brief answers to them. If you’d like to know more about these topics, ask your doctor.

Is Myrbetriq similar to alternatives such as oxybutynin, Vesicare, Toviaz, and Flomax?

Yes, Myrbetriq has some similarities to its alternatives.

Like Myrbetriq, the following drugs can all be prescribed to treat certain bladder problems:

In fact, Myrbetriq is sometimes prescribed in combination with Vesicare to treat overactive bladder. But each of these medications contain different active drugs. And they each work differently in your body than Myrbetriq.

To learn more about the similarities and differences with these drugs, talk with your doctor or pharmacist.

Will I have weight gain or weight loss with Myrbetriq?

Most likely, no. Weight changes weren’t reported as side effects in clinical studies of Myrbetriq.

However, drugs other than Myrbetriq that are prescribed to treat overactive bladder may cause weight gain. This includes the drug darifenacin (Enablex).

If you’re concerned about weight changes while taking Myrbetriq, talk with your doctor. They can recommend ways to maintain a weight that is healthy for you while taking the drug.

What should I know about stopping Myrbetriq? Can I stop it ‘cold turkey’?

It’s best to talk with your doctor before stopping Myrbetriq.

The drug isn’t known to cause withdrawal symptoms when it’s stopped. (Withdrawal symptoms are side effects that may happen if you stop taking a drug your body has become dependent on.) Such symptoms weren’t reported in clinical studies of Myrbetriq.

But keep in mind that symptoms of the condition you’re using Myrbetriq to treat may return after you stop the drug. It’s best to continue taking Myrbetriq until your doctor says it’s safe to stop. They’ll advise you on the safest way to stop taking Myrbetriq and whether you can stop it suddenly (“cold turkey”). They may want to prescribe a different drug to treat your condition.

Does Myrbetriq cause dementia, hair loss, or kidney problems?

No, Myrbetriq likely doesn’t cause dementia or hair loss. (Dementia is a condition that causes problems with communication, memory, and behavior.) These conditions weren’t reported as side effects in clinical studies of Myrbetriq.

Other drugs prescribed to treat overactive bladder may increase the risk of dementia. These include:

Myrbetriq isn’t known to directly cause kidney problems. This also wasn’t reported in clinical studies of the drug. But other side effects of Myrbetriq can lead to kidney problems if they’re severe or left untreated. This includes conditions such as:

If you’re concerned about having dementia or hair loss with Myrbetriq, talk with your doctor. They can advise on your risk of these side effects with Myrbetriq.

Also, if you’re concerned about your risk of kidney problems while taking Myrbetriq, tell your doctor. If you have symptoms of a UTI or urinary retention, let your doctor know right away. They may recommend treatment to help lower your risk of kidney problems.

Can Myrbetriq be taken for erectile dysfunction (ED) or interstitial cystitis (IC)?

Myrbetriq isn’t currently approved to treat erectile dysfunction (ED) or interstitial cystitis (IC). But doctors may prescribe the drug off-label for these conditions. With off-label use, doctors prescribe a drug for a purpose other than what it’s approved for.

ED is the inability to get or keep an erection. IC is a bladder problem that causes bladder pain and frequent urination. But IC is different than overactive bladder, which Myrbetriq is approved to treat.

If you’re interested in using Myrbetriq to treat ED or IC, talk with your doctor. They can advise the right treatment for your condition.

Is Myrbetriq safe to take?

Myrbetriq is generally considered safe to take. But the drug can cause mild or serious side effects for some people. For details about possible side effects, see the “Myrbetriq: Side effects” section above.

If you’re concerned about the safety of Myrbetriq, talk with your doctor or pharmacist. They can discuss your risk of side effects with the drug.

Myrbetriq: Cost

Like other medications, prices for Myrbetriq may vary. The drug’s price will depend on factors such as:

Cost considerations for Myrbetriq

Here’s a list of things to consider when looking into the cost of Myrbetriq:

  • Option for a 90-day supply. For some drugs, it’s possible to get a 90-day supply. If this option is approved by your insurance company, it can help lower the cost of the drug. It can also help you avoid frequent trips to your pharmacy. If you’d like to learn more about this option, ask your doctor or pharmacist, or contact your insurance company.
  • Need for prior authorization. Before insurance coverage for Myrbetriq is approved, your insurance company may require prior authorization. In this case, your doctor and insurance company will communicate about your prescription for Myrbetriq. Then, the insurance company will decide if the drug will be covered. To find out if you need prior authorization for Myrbetriq, contact your insurance company.
  • Possible cost assistance options. Financial assistance to help lower the cost of Myrbetriq is available. Astellas Pharma US Inc., the manufacturer of the drug, offers a savings card to lower the cost of Myrbetriq. It also offers additional financial assistance through the Astellas Patient Assistance Program. To learn more about these options, visit the manufacturer’s website. Also, check out this article to learn about ways to save on prescription drugs.

It can also allow you to get the drug without leaving home. To find out more about this option, check with your doctor, pharmacist, or insurance company.
  • Availability of a generic form. Myrbetriq doesn’t come in a generic form. A generic drug is an exact copy of the active drug in a brand-name medication. Typically, generics cost less than brand-name drugs.

Myrbetriq: How it works

Myrbetriq is approved to treat the conditions below:

  • Overactive bladder (OAB). Myrbetriq is used in adults with OAB who have urinary urgency, frequency, and incontinence.
  • Neurogenic detrusor overactivity (NDO). Myrbetriq is used in children ages 3 years and older with neurogenic detrusor overactivity. NDO is a type of overactive bladder that’s caused by a nerve problem.

To learn more about these conditions, see the “Myrbetriq: Uses” section above.

Myrbetriq belongs to a drug class called beta-3 agonists. The drug works* by attaching to beta-3 cells on the bladder. This allows the bladder muscles to relax, helping it to hold more urine. This is how Myrbetriq eases the symptoms of OAB and NDO.

* The way a drug works in your body is called its “mechanism of action.”

How long does Myrbetriq take to start working?

Myrbetriq starts working to treat your condition as soon as you take it. But it may take several weeks for your symptoms to ease.

How long does Myrbetriq stay in your system?

Myrbetriq stays in your system for about 10 days after you take it.

Myrbetriq and alcohol

There aren’t any known interactions between Myrbetriq and alcohol.

However, keep in mind that drinking alcohol can lead to increased urination, which may worsen symptoms of overactive bladder (OAB). Myrbetriq is prescribed to treat OAB. So drinking alcohol while taking the drug could make it hard to tell if the drug is working well for you.

If you drink alcohol, your doctor can recommend the amount that’s safe for you to drink while taking Myrbetriq.

Myrbetriq: How to take

Your doctor will recommend how you should take Myrbetriq. It’s important that you take the drug exactly as your doctor instructs.

  • Can Myrbetriq be chewed, split, or crushed? No, you shouldn’t chew, split, or crush Myrbetriq tablets. You should swallow the tablets whole. If you have trouble swallowing Myrbetriq tablets, talk with your doctor or pharmacist. With Myrbetriq granules, a pharmacist will mix them with water to form a liquid solution that’s taken by mouth. If any granules remain in the mixture, they should not be chewed. Instead, they should be swallowed with the liquid without being chewed.
  • Is there a best time of day to take Myrbetriq? No, there isn’t a best time of day to take Myrbetriq. The drug is typically taken once daily. It can be taken any time of day, but try to take your doses around the same time each day.
