How to Manage Your Overactive Bladder
What Exactly is Overactive Bladder?
Overactive bladder (OAB) is a common condition that can affect up to roughly 40% of women in their lifetime. OAB can lead to urinary incontinence - the loss of bladder control, an embarrassing problem. More than 33 million Americans suffer from overactive bladder.
Those with OAB, also called urge incontinence, experience a sudden, strong urge to urinate during the day and night; they may also leak urine before getting to the restroom.
OAB results in someone needing to urinate more than the usual 7 to 8 times per 24 hours. Therefore, OAB symptoms usually consist of four symptoms: an urgent need to urinate, a need to urinate more frequently than normal, waking from sleep to urinate, and urgency incontinence (urine leakage). OAB is not due to effects from a urinary tract infection or from a neurologic condition such as multiple sclerosis.
Is Overactive Bladder (OAB) the Same as Stress Incontinence?
No. Stress incontinence occurs when pelvic muscles, located beneath the bladder, are not strong enough. These muscles cannot handle any pressure being exerted on the bladder, and this leads to urine leaking.
Stress incontinence may occur when someone is sneezing, lifting heavy items, laughing, or coughing. Pregnancy and after childbirth is also a time when stress incontinence may be bothersome, and it may continue to be a problem long after childbirth.
Urgency incontinence is another name for overactive bladder (OAB). Stress incontinence and OAB can also occur together, known as mixed incontinence.
Other types of incontinence include overflow incontinence and functional incontinence.
How Will I Know if a Urinary Tract Infection is Causing My Symptoms?
Leaking of urine, whether a small or large amount of urine, is the main symptom of incontinence due to overactive bladder (OAB). OAB can also lead to leakage during sleep. Urine leakage due to a urinary tract infection (UTI) is usually a short-term problem, but visit your doctor as you may need an antibiotic. If urine leakage is accompanied by the following symptoms, you may have a UTI.
- Pain or a burning sensation during urination; a fever
- Pink or red urine discoloration
- A strong urine odor or cloudy urine
- Stomach or back pain
- Frequent urination
How is an Overactive Bladder Diagnosed?
If you are experiencing overactive bladder (OAB) symptoms, and especially if they interfere with your normal routines like sleep, work or leisure time, see your doctor.
Leaking urine at any age is not normal. Do not feel ashamed or embarrassed to mention these symptoms to your doctor; OAB is a common condition for which many women seek treatment.
During your doctor visit, your medical history will be reviewed, and you may be asked to keep a voiding dairy for a few days. A neurologic and pelvic exam will be done, and your doctor may check your urine for signs of a UTI. Depending upon your results, imaging tests like a CT or MRI may be needed to determine if your OAB is due to a nerve injury.
What Treatments are Suggested for OAB?
For women who suffer with overactive bladder (OAB) symptoms treatment options include:
- Pelvic muscle exercises
- Bladder management techniques
- Prescription and over-the-counter medications
Kegel exercises which strengthen the pelvic muscles can improve symptoms, especially in stress incontinence. Bladder retraining, such as scheduled bladder emptying, behavioral modification, and fluid management can also be useful for OAB.
What is Fluid Management for OAB?
It is important not to severely restrict fluids for overactive bladder (OAB) as this could lead to dehydration. However, most people need roughly 4 to 8 eight ounce glasses of fluid per day; more may be required with exercise, hot weather, or excessive perspiration.
It's true that cutting back on fluids may help with leakage and embarrassing moments. However, if you do not drink enough liquids, your urine may become dark and concentrated and dehydration may occur. One option is to drink small amounts at regular intervals throughout the day, instead of a large glass all at once. If you awaken frequently at night to urinate, avoid fluids right before bed, and cut back on alcohol and caffeine.
Which Medications are Used for OAB?
Your doctor may use multiple strategies to relieve your overactive bladder (OAB) symptoms. In addition to the exercises and behavioral modifications, many medications are available; one is even available over-the-counter. Extended-release forms may cause less dry mouth as a side effect. Medications include:
Tolterodine (Detrol, Detrol LA)
Detrol and Detrol LA are brand names of tolterodine, approved to treat overactive bladder (OAB) with symptoms of urinary frequency, urgency, and incontinence (urine leakage). Tolterodine acts as an antispasmodic on the bladder muscles to lessen the symptoms of OAB.
Detrol and Detrol LA are both available in cost saving generics. The extended-release formulation is given once daily, and the immediate-release is given twice-a-day.
Common side effects include constipation, dry mouth, headache, or drowsiness. If serious allergic reactions - like swelling of your lips, throat or face, difficultly breathing or swallowing, itch, or rash appear, call 911 immediately. Tolterodine should be avoided in patients with a heart rhythm condition (arrhythmia) due to possible worsening of their condition (QT prolongation).
Oxybutynin (Ditropan, Ditropan XL, Oxytrol, Oxytrol For Women, Gelnique)
Oxybutynin is available in many different dose forms, both over-the-counter and by prescription. Prescription Ditropan and Ditropan XL (both also generic) are tablet formulations. Gelnique is a prescription gel form applied to the skin (transdermal) once daily. In 2013, the first over-the-counter (OTC) treatment for overactive bladder (OAB) in women, Oxytrol For Women, was FDA approved. Oxytrol For Women is a patch applied to the skin every four days; Oxytrol is still available with a prescription, too. Both versions have the same formulation and same dosage strength, but Oxytrol for Women is only indicated for women 18 years of age or older. For any other use, including in men, a prescription is needed. Oxytrol side effects include skin irritation, dry mouth, and constipation. Transdermal delivery of oxybutynin by gel or patch may reduce side effects. Cost for a one month supply of OTC Oxytrol is roughly $25 to $30.
Trospium (Sanctura, Sanctura XR)
Sanctura and Sanctura XL (extended-release form) are known generically as trospium, and both forms are available in a cost-saving generic form. The tablets are taken either once or twice a day, and should be taken on an empty stomach one hour before meals.
As with other many drugs used to treat overactive bladder (OAB), trospium can cause side effects such as constipation, dry mouth, drowsiness, blurred vision and headache. A severe, but uncommon allergic side effect that may require emergency treatment is angioedema -- a swelling of the face, lips, tongue, and throat. Angioedema can be life-threatening. STOP the medication and call 911 if this reaction occurs.
VESIcare (solifenacin), first approved in 2004, is taken by mouth in tablet form once a day. Generic solifenacin has been approved by the FDA. Like all of the oral muscarinic antagonists used for overactive bladder, side effects like dry mouth, blurred vision, and drowsiness may occur. If you have any kind of heart electrical issue, such as atrial fibrillation, you may need to avoid VESIcare due to worsening of your heart condition. It is important you do not use muscarinic antagonists like VESIcare if you have any form of gastric (stomach) retention, narrow-angle glaucoma, or urine retention.
Due to the common anticholinergic side effects that occur with this drug class, constipation may be severe, so check with your doctor if this problem arises. If you have liver disease you may need a lower dose of Enablex; if you have severe liver disease should not use Enablex. In addition, Enablex undergoes breakdown in the liver and can lead to multiple drug interactions, so always have your provider check for interactions.
The use of overactive bladder (OAB) medications can be a problem for patients who are sensitive to side effects like dry mouth, constipation, and blurred vision. Myrbetriq (mirabegron) by Astellas Pharma is an oral, extended-released tablet FDA-approved in 2012. Myrbetriq works by a new mechanism of action to stimulate beta-3 receptors, causing bladder muscle relaxation and improved bladder storage.
Myrbetriq side effects include high blood pressure and the risk for urinary retention in patients receiving other antimuscarinic agents for OAB or with bladder outlet obstruction. Myrbetriq can also result in serious drug interactions, so have your pharmacist run a drug interaction check.
Botox (onabotulinumtoxinA) is approved to treat overactive bladder (OAB) when typical anticholinergic agents do not work well, cannot be taken, or if side effects interfere with therapy. It takes roughly 2 weeks for symptoms to subside. One Botox dose, which requires injection into the bladder muscle via a special procedure, lasts for up to 6 months.
In treating OAB, the most common side effects are urinary tract infection, painful or difficult urination, and a temporary inability to fully empty the bladder. In clinical trials, about 6 out of every 100 patients were unable to fully empty their bladder following Botox treatment. If this happens, you may have to temporarily use a disposable self-catheter to drain urine. Talk to your doctor about this possibility, and other Botox side effects.
Toviaz (fesoterodine) by Pfizer is a muscarinic antagonist (anticholinergic) agent used for overactive bladder (OAB). Toviaz is available in an extended-release tablet in 4 and 8 milligrams (mg) taken once-a-day.
If you have an allergy to tolterodine (Detrol, Detrol LA), you should not take Toviaz as it is chemically-related. Patients who take certain drugs such as ketoconazole, itraconazole, and clarithromycin should not use the 8 mg dose due to a specific drug interaction with an enzyme system called cytochrome P450 3A4.
Many Americans Struggle With Incontinence
There is a wide array of overactive bladder (OAB) treatments, and a 2015 FDA report discusses overactive bladder (OAB) and it's implication on health. OAB can have a negative impact on social, family and work routines. Experts state that patients need to take the first step to seek advice from their doctor to determine whether their symptoms are due to OAB or another condition and which treatment is the best.
If you have OAB, you are not alone. OAB is common in older women (50 percent), but about 25 percent of older men suffer from its effects, too. If you suffer from OAB, considering talking to your healthcare provider about treatment options.
