Tolterodine (Detrol) is used to treat overactive bladder (OAB) symptoms, such as loss of bladder control and the need to go to the restroom suddenly or often. This medication can commonly cause dry mouth, but other side effects can include headache, dizziness, and constipation. There are immediate-release (IR) and extended-release (ER) versions of tolterodine (Detrol). Both formulations are available as brand-name and generic-name medications. Tolterodine (Detrol) can interact with anticholinergics, like diphenhydramine (Benadryl).
Overactive bladder (OAB)
Tolterodine (Detrol) is an anticholinergic medication that's considered a urinary antispasmodic. It blocks certain receptors in the bladder so that your bladder muscles can relax. This helps with bladder spasms, the urge to urinate, and control over your urination.

Works well for OAB symptoms by helping you control your urge to urinate
Causes less dry mouth than oxybutynin
Extended-release version is taken only once a day
Available as a lower-cost, generic version
Can raise your risk for falls because it can make you feel drowsy or dizzy
Can cause severe dry mouth and constipation
Can't use if you have an allergy to Toviaz (fesoterodine), which is another OAB medication
You can take tolterodine (Detrol) with or without food. Food won't affect how well this medication works.
For the extended-release capsules: Take the extended-release capsules with water, and swallow them whole. Don't break, crush, or chew the capsules.
Take tolterodine (Detrol) every day even if you don't see results right away. For the medication to work well, you have to take it consistently. Lifestyle changes, such as pelvic muscle exercises and changes to your diet, can also help with OAB symptoms.
Tolterodine (Detrol) can cause drowsiness, dizziness, and blurry vision. Don't drive or do things that require your full attention until you know how this medication makes you feel.
If you experience dry mouth while taking tolterodine (Detrol), try chewing sugar-free gum or sucking on a sugar-free hard candy. If it's really bothersome, ask your provider about switching to the extended-release form because it might cause fewer side effects.
Make sure you're not taking tolterodine (Detrol) with other anticholinergics, like diphenhydramine (Benadryl). These medications work similarly to tolterodine (Detrol), and they have similar side effects. Taking anticholinergic medications with tolterodine (Detrol) can make side effects, like dry mouth, headache, and dizziness, worse.
Tolterodine (Detrol) can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.
Tolterodine (Detrol) can cause swelling of the face, lips, tongue, or throat. This can happen right after taking the first dose or after taking the medication for a while. If you experience facial swelling, difficulty breathing, a blockage in your airway, or sudden dizziness, stop taking the medication and get emergency medical help right away.
Risk factors: Drinking alcohol | Taking other medications that make you less alert
Tolterodine (Detrol) can make you feel dizzy, drowsy, or less alert, particularly when you first start the medication or increase your dose. Don't drive or do things that require you to focus until you know how this medication affects you.
Risk factors: History of narrow-angle glaucoma
Tolterodine (Detrol) can cause temporary changes to your vision, like blurred vision. Though rare, anticholinergic medications like tolterodine (Detrol) can also raise the risk of narrow-angle glaucoma. Tolterodine (Detrol) can't be used if you have uncontrolled narrow-angle glaucoma. Check with your eye doctor if you're unsure what type of glaucoma you have.
Risk factors: History of bladder problems | History of stomach or intestine problems
Let your healthcare provider know if you have problems urinating due to a blockage in your bladder. Tolterodine (Detrol) can make it difficult for you to empty your bladder fully. This can worsen your bladder problem.
Also tell your provider if you have blockages in your stomach or intestines. Tolterodine (Detrol) can slow down your digestion, which can make your stomach symptoms worse.
Risk factors: History of liver or kidney problems
Let your healthcare provider know if you have liver or kidney problems. Your liver helps break down tolterodine (Detrol) in the body, and your kidneys help get rid of the medication from your system. When these organs aren't working well, the medication can stay in your body longer and build up. This might raise the risk of side effects, such as dry mouth and dizziness. To lower this risk, your provider might prescribe a lower dose of tolterodine (Detrol) for you if you have liver or kidney problems. But, tolterodine (Detrol) isn't recommended if you have severe liver or kidney disease.
If you have myasthenia gravis (MG), a condition that causes your muscles to feel weak, talk to your provider before taking tolterodine (Detrol). This medication can worsen your MG symptoms.
Risk factors: History of heart rhythm problems | Taking medications to control heartbeat
Let your healthcare provider know if you're taking medications to control your heartbeat or if you have an irregular heart rhythm. Tolterodine (Detrol) might cause changes in your heartbeat that can be dangerous. Your provider will discuss with you about the risks and benefits of taking this medication.
The typical starting dose is 2 mg by mouth two times a day. Your healthcare provider might lower the dose to 1 mg two times a day based on how you respond to the medication.
Extended-release capsules: The typical starting dose is 4 mg by mouth once a day with water. Your healthcare provider might lower the dose to 2 mg once a day depending on how you respond to the medication.
Your dose might differ if you have kidney problems, liver problems, or if you take certain medications that interact with tolterodine (Detrol).
Using this medicine with any of the following medicines is not recommended. Your doctor may decide not to treat you with this medication or change some of the other medicines you take.
Using this medicine with any of the following medicines is usually not recommended, but may be required in some cases. If both medicines are prescribed together, your doctor may change the dose or how often you use one or both of the medicines.
Using this medicine with any of the following medicines may cause an increased risk of certain side effects, but using both drugs may be the best treatment for you. If both medicines are prescribed together, your doctor may change the dose or how often you use one or both of the medicines.
