What other drugs will affect Vyvanse?

Ask your doctor before using a stomach acid medicine (including Alka-Seltzer or sodium bicarbonate). Some of these medicines can change the way your body absorbs lisdexamfetamine, and may increase side effects.

Other drugs may interact with lisdexamfetamine, including prescription and over-the-counter medicines, vitamins, and herbal products. Tell your doctor about all your current medicines and any medicine you start or stop using.

How should I take Vyvanse?

Take Vyvanse exactly as prescribed by your doctor. Follow all directions on your prescription label. Your doctor may occasionally change your dose. Do not take this medicine in larger or smaller amounts or for longer than recommended.

Lisdexamfetamine may be habit-forming. Never share Vyvanse with another person, especially someone with a history of drug abuse or addiction. Keep the medication in a place where others cannot get to it. Selling or giving away this medicine is against the law.

Take Vyvanse with or without food, first thing in the morning.

Read all patient information, medication guides, and instruction sheets provided to you. Ask your doctor or pharmacist if you have any questions.

The chewable tablet must be chewed before you swallow it.

Do not crush, chew, break, or divide a Vyvanse capsule. Swallow the capsule whole.

To make swallowing easier, you may open the capsule and sprinkle the medicine into a glass of water or orange juice, or mix it with yogurt. After the medicine has dissolved, drink or eat the mixture right away. Do not save for later use.

While using this medicine, your doctor will need to check your progress at regular visits. Tell any doctor who treats you that you are using this medicine.

What happens if I miss a dose?
