How Vesicare Works
Solifenacin reduces spasms of the bladder muscles. Minimising the bladder’s muscle contractions decreases the feeling of urgency. Controlled bladder spasms helps to prevent frequency and incontinence. Solifenacin is in a class of drugs called muscarinic receptor antagonists.
Storage, Dosage, How to use Vesicare
Use Vesicare once a day. Do not crush or chew the tablets. Swallow whole with water.
When using the liquid form of Vesicare, begin by shaking the bottle vigorously before measuring the dose. Should too much medicine be accidently withdrawn into the syringe, discard the extra amount. Do not return the unused medicine back into the bottle.
If not using the dosing syringe, use an accurate dose-measuring utensil or device. Do NOT rely on an unmarked spoon to pour the dose.
After taking the liquid form, follow with a glass of water or milk. Avoid food or anything other than water and milk to avoid the bitter aftertaste.
Store either form of Solifenacin, tablet or liquid, at room temperature with firmly closed lids. Keep the medication away from heat and moisture. Also keep this medication out of reach of children. This drug is for adults only. Throw away what is left of the liquid form after 28 days.
