What does it do?

Lisdexamfetamine is used to treat ADHD (Attention Deficit Hyperactivity Disorder).

Before you start

• Tell your doctor if you have heart or mental health problems, angle-closure glaucoma, Tourette’s syndrome, high blood pressure, or if you have ever had a seizure.
• Tell your doctor if you are pregnant, planning to become pregnant, or breastfeeding.

How should you take it?

Take lisdexamfetamine regularly as directed with a glass of water. You can take it with or without food.
If you have trouble swallowing, you can open the capsule and mix the contents with a small amount of soft food or liquid.
It is best to take lisdexamfetamine in the morning, as it can cause trouble sleeping.

Do not stop taking lisdexamfetamine without talking to your doctor first.

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 lisdexamfetamine including:

• urinary alkalinisers containing sodium bicarbonate (e.g. Ural®)
• some migraine medicines, such as sumatriptan (e.g. Sumagran Active®)

Tell your pharmacist or doctor about all medicines or treatments that you may be taking, including vitamins, herbal products or recreational drugs.
