What does it do?

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

How should you take it?

Take tolterodine regularly as directed with a glass of water.

What if you forget a dose?

Take the missed dose as soon as possible. If it is close to the time for your next dose, skip the missed dose and carry on as normal. Do not take two doses at the same time.

Can you take other medicines?

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

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

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.

Other information:

  • Tell your doctor if you have heart, liver, kidney, bowel, prostate or eye problems (glaucoma).
  • Tell your doctor if you have Parkinson’s disease or a chronic muscle condition (e.g. myasthenia gravis).
  • Tell your doctor if you are pregnant, planning to become pregnant, or breastfeeding.
