Actually, yes you can open it, but I don't think you should be changing the dose without the doctors approval. This is from Drugs A to Z:How should I take Vyvanse?
Take Vyvanse exactly as prescribed by your doctor. Do not take in larger or smaller amounts or for longer than recommended. Follow the directions on your prescription label.
Your doctor may occasionally change your dose to make sure you get the best results.
Do not take Vyvanse in the evening because it may cause sleep problems (insomnia).
Vyvanse may be taken with or without food.
The capsule should be swallowed whole. You may also open the Vyvanse capsule and sprinkle the medicine into a glass of water. After the medicine has dissolved, drink this mixture right away. Do not save the mixture for later use. Discard the empty capsule.
Hope this helps you...
