What does it do?

Solifenacin is used to treat incontinence (peeing when you don't want to). It reduces the urge and how often you need to pee.

Before you start

• Tell your doctor if you have prostate or bowel problems, or angle-closure glaucoma.
• Tell your doctor if you are pregnant, planning to become pregnant, or breastfeeding.

How should you take it?

Take solifenacin regularly as directed with a glass of water. You can take it with or without food.

What if you forget a dose?

If it is nearly time for your next dose, skip the missed dose and take your next dose at the usual time. Otherwise, take the missed dose as soon as you remember. Do not take two doses at the same time.
