Solifenacin succinate, also known by the brand name Vesicare, is an anticholinergic medication that's used to treating certain bladder problems. The brand-name and generic tablets help treat overactive bladder in adults. A liquid suspension under the brand name Vesicare LS is also available for children with neurogenic detrusor overactivity (NDO) (urinary incontinence due to a neurologic problem). This medication is taken by mouth once per day. The most common side effects are dry mouth and constipation.

Solifenacin (Vesicare) is an antimuscarinic medication. It's more commonly known as an anticholinergic. This is because antimuscarinics and anticholinergics work very similarly to each other.
Solifenacin (Vesicare) blocks a chemical in the body called acetylcholine from attaching to muscarinic receptors in the bladder. This causes your bladder muscles to relax. The medication helps you to go to the bathroom less often and have better control of urination.

You can take solifenacin (Vesicare) with or without food. Sometimes, the medication can upset your stomach. If this happens, you can try taking it with food to help lessen this side effect.
Swallow solifenacin tablets (Vesicare) whole. Don't chew, cut, or crush them. Talk to your prescriber if you're having trouble swallowing the tablets whole.
Solifenacin (Vesicare) can cause dry mouth and dry skin. Staying hydrated and chewing sugar-free gum can help you manage dry mouth. And moisturizing your skin often and avoiding harsh soaps can help with dry skin.
Solifenacin (Vesicare) can cause dizziness, sleepiness, and blurry vision. Don't drive, operate machinery, or do anything that requires concentration until you know how this medication affects you. It's best to avoid drinking alcohol while you're taking solifenacin (Vesicare) because alcohol can worsen sleepiness.
Solifenacin (Vesicare) can make you sweat less, which can put you at risk for getting overheated easily, especially when it's hot. To avoid overheating, try not to be outside during the hottest time of the day and avoid dehydrating beverages, like alcohol.
Tell your healthcare team if you're pregnant or planning to become pregnant. It's not completely known whether solifenacin (Vesicare) can harm your unborn baby.
Let your primary care provider know if you're breastfeeding or planning to nurse. Taking solifenacin (Vesicare) for a long time can lower your milk supply. It's also possible for your baby to have side effects from the medication. Your care team can recommend safe feeding options while you're taking solifenacin (Vesicare).
More tips for the solifenacin liquid suspension (Vesicare LS):
Shake the bottle well to mix the medication before you draw up the dose into an oral syringe.
Only use the oral syringes from the pharmacy to measure out the dose. Ask the pharmacy for extras if you need to. Don't use household spoons to measure and take the dose. Household spoons might not be accurate.
Swallow the measured dose of the liquid suspension, then drink water or milk afterwards. It's best not to take the medication at the same time as food or other drinks because it'll cause a bitter taste.
Store the liquid suspension at room temperature and keep it in the original bottle it came in. Throw the bottle away after 28 days of opening it, even if there's still some medication left inside.
Solifenacin (Vesicare) 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.
Some people who took solifenacin (Vesicare) have reported experiencing an uncommon, but serious side effect called angioedema. This involves swelling in different parts of the body, including the face, throat, tongue, or around the eyes. Swelling of the tongue or throat area can be life-threatening, since it can make it hard to breathe. Go to the emergency room right away if you suddenly can't breathe or notice swelling around your face or throat.
Risk factors: Taking other medications that cause nervous system side effects
Solifenacin (Vesicare) can cause sleepiness, dizziness, headache, and confusion. It might also cause hallucinations (seeing or hearing things that aren't real). Watch for side effects particularly after you start the medication and after your dose gets raised. Let your care team know if you have any of these side effects, especially if they affect your usual daily activities. Don't drive or do any activities that require a lot of attention until you know how solifenacin (Vesicare) makes you feel.
Be sure your care team knows about the other medications you take or plan to take. Taking solifenacin (Vesicare) with other medications that can make you tired can make side effects like sleepiness and dizziness worse. This can raise your risk for falls or other accidents.
Solifenacin (Vesicare) typically isn't recommended for people with health conditions that cause slowed gut movement. And people with blockages in their gut can't take this medication at all. This is because solifenacin (Vesicare) can slow the gut even more and worsen the digestive condition.
Let your primary care provider know if you have any problems with the digestive system, like gastroparesis (delayed stomach emptying). Your care team can check to see whether solifenacin (Vesicare) is safe for you.
If you have glaucoma and you do take solifenacin (Vesicare), tell your ophthalmologist that you're taking this medication so they know to follow up with you more closely. You might need to get eye exams done more often to check your eye health.
Risk factors: History of QT prolongation | Taking other medications that cause this same heart rhythm problem | Taking higher-than-recommended doses of solifenacin (Vesicare)
Some people who took solifenacin (Vesicare) at higher-than-recommended doses had changes to their heart rhythm called QT prolongation. This happens when it takes longer than usual for your heart to pump and then relax. Call 911 right away if you feel your chest pounding, have chest pain, have shortness of breath, or feel faint or lightheaded while you're taking this medication. These can be signs of irregular heart rhythm.
Solifenacin (Vesicare) generally isn't recommended for people who are at risk for QT prolongation, including people who have abnormal electrolyte levels or who take other medications that cause QT prolongation.
Tablets (adults only): The typical dose is 5 mg to 10 mg by mouth once a day.
Liquid suspension (children age 2 and older): The dose depends on your child's weight. In general, the dose ranges from 2 mL to 10 mL by mouth once a day. Each mL contains 1 mg of medication.
