What does it do?

Solifenacin is used to treat incontinence. It reduces the urge and how often you need to pee.

How should you take it?

Take solifenacin regularly as directed with a glass of water.

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.

Can you take other medicines?

Some medicines available without a prescription may react with solifenacin including:

  • some antihistamines (may be in anti-allergy, anti-nausea and cough/cold medicines)
  • meclozine (e.g. Sea-legs®)
  • prochlorperazine (e.g. Buccastem®)

Tell your pharmacist or doctor about all medicines or treatments that you may be taking, including vitamins, herbal products (e.g. St John's wort) or recreational drugs.
