Toviaz™ Uses

Do you have the urge to use the restroom more than most people seem to? What about urinary leakage? If so, don’t worry. These problems are more common than you likely know. And there are plenty of medications available to help, the newest of which is Toviaz™.

The active ingredient in Toviaz™ is fesoterodine. This chemical is part of a class of drugs known as antimuscarenics. These drugs decrease involuntary bladder spasms by attaching to chemicals in your brain.

Manufactured by Pfizer, Toviaz™ comes in an extended-release tablet form. It is available in 4mg and 8mg. You should not break or chew the tablets, and you should take them only as your doctor prescribes them.

Toviaz™  is a fairly new drug for incontinence. The downfall is that it is quite expensive. An average monthly prescription runs $100-200 before insurance. At this point, there is no generic form available.  The patent does not expire until 2019, so a generic will not be available anytime soon.

While the price is high, Toviaz™  has proven to be very effective in clinical trials. Pfizer treated 2288 patients with fesoterodine (782 with 4mg and 785 with 8mg). The trials showed that Toviaz lowered urge incontinence and stress incontinence. It also increased the amount of urine voided during each trip to the restroom.


Toviaz™  Side Effects

Another benefit of Toviaz™  is that it has fewer side effects when compared to older drugs that come in a generic form. Dry mouth and constipation were the two most complained of side effects during the trials. 18.8% of those taking 4mg and 34.6% of those taking 8mg experienced dry mouth. And 4.2% of those taking 4mg and 6.0% of those taking 8mg complained of constipation. The other reported side effects were under 5% for both 4mg and 8mg forms.

However, rare instances of severe side effects did occur. If you experience any of the following while on Toviaz™, contact your doctor immediately:

  • chest pain
  • fast or uneven heart rate
  • swelling of feet or hands
  • urinating less than usual or not at all
  • painful or difficult urination

Some of the less severe side effects include the following. While these are not usually life-threatening, they can be uncomfortable. Track the frequency and extent of your side effects and let your doctor know about them at your next visit.

  • dry mouth
  • dry eyes
  • dizziness
  • drowsiness
  • constipation
  • stomach pain
  • cough and dry throat
  • back pain
  • insomnia

Don’t try to treat these symptoms yourself, as some medications can interfere with Toviaz™. It’s important to let your doctor know about the side effects so he or she can recommend the best treatment.

Additionally, you should let your doctor and pharmacist know about any medications you’re taking before you start Toviaz™. Even over-the-counter and herbal remedies may have interactions with your medicine. And if your doctor puts you on a new medication once you’re on Toviaz™, make sure he or she knows about the incontinence prescription.

Finally, it’s best to let your doctor know about any medical conditions you have before starting Toviaz™. Tell your physician about any preexisting conditions, especially

  • urinary blockage
  • stomach or intestinal blockage
  • glaucoma
  • liver disease
  • kidney disease
  • urination problems
  • myasthenia gravis
  • severe constipation
