For most people with an overactive bladder, the recommended starting dosage of fesoterodine is 4 mg once a day. If your symptoms do not improve with this dosage, your healthcare provider may increase it to 8 mg once daily. However, it is important to know that in clinical studies, higher doses were more likely to cause side effects.
The dose of fesoterodine fumarate (Toviaz™) that your healthcare provider recommends will vary, depending on a number of factors, including:
- How you respond to fesoterodine
- Other medications you may be taking
- Other medical conditions you may have.
As is always the case, do not adjust your dosage unless your healthcare provider specifically instructs you to do so.
The recommended starting dose of fesoterodine for overactive bladder treatment is 4 mg once daily. If your overactive bladder symptoms are not adequately controlled at this dose, your healthcare provider may increase your dose to 8 mg once daily. In studies, the higher dosage was generally more likely to cause side effects; some people may not tolerate this dose well.
If you have severe kidney problems or are taking certain other medications that increase the level of fesoterodine in your blood, the maximum recommended dose is 4 mg once daily (see Drug Interactions With Fesoterodine for more information). Make sure your healthcare provider and pharmacist has a complete list of all the medications you take.
General Information on Taking Your DoseConsiderations for people taking fesoterodine include the following:
- Fesoterodine comes in extended-release tablet form. It is taken just once a day.
- Because this is an extended-release medication, it should be swallowed whole with liquids. Do not break, chew, or crush the tablets.
- You can take fesoterodine on an empty stomach or with food. If it seems to bother your stomach, try taking it with food.
- Fesoterodine should be taken at the same time each day, in order to maintain an even level of the medication in your blood.
- For the medication to work properly, it must be taken as prescribed.
- If you are unsure about anything related to your fesoterodine dosage, talk to your doctor, nurse, or pharmacist.
