Side Effects of Fesoterodine (Toviaz)

Fesoterodine, known as the brand Toviaz, is an antispasmodic used to treat an overactive bladder. An overactive bladder is a condition in which the bladder muscles contract uncontrollably and cause a frequent and urgent need to urinate.

 

Toviaz works by relaxing the muscles in your bladder and reducing spasms,. This provides Toviaz the ability to control the bladder. This reduces feelings of needing to urinate immediately and decreases frequent trips to the bathroom. It also helps to reduce the leaking of urine.

 

Before taking fesoterodine, be sure to tell your doctor and pharmacist about all the prescription drugs, over-the-counter medications and herbal products you use (Toviaz label published by the FDA).

 

Fesoterodine comes as an extended release tablet that is taken my mouth. It can be taken with or without food. Your doctor may start you on a low dose and increase as needed. However, it may take up to twelve weeks to experience symptom relief.

Serious Side Effects

The severe side effects of Toviaz, according to the FDA, are:

 

  • Increased heart rate
  • Difficulty swallowing and breathing
  • Hoarseness
  • Swelling on the face, throat, tongue or lips

 

Contact your doctor immediately if you experience any of these adverse effects.

Common Side Effects

Toviaz is associated with a number of side effects that mostly subside: constipation, dry mouth, dry eyes, difficulty emptying the bladder, cough, dry throat, or back pain.

About Pharmacogenetic Testing

Toviaz is actively metabolized in the liver by carboxy, carboxy-N-desisopropyl, and N-desisopropyl metabolites involving the gene polymorphisms CYP2D6 and CYP3A4 as reported by the FDA.

 

Pharmacogenetic testing allows your physician to determine what drugs you may take safely, and what drugs you should avoid. With the pharmacogenetic test results, your prescriber can determine safe dosing and frequency depending on how well your body is able to process the drug.
