Vyvanse VS Adderall XR?

I heard that adderall is stronger. For example 30mg of adderall is stronger than 30 mg of Vyvanse. is this true?

Both VYVANSE and Adderall are amphetamine. However, only about 30% of VYVANSE is acutal amphetamine, whereas with adderall, 100% of the given mg's is amphetamine.

Thus, the actual conversion rates are roughly:
10mg AdderallXR = 30mg VYVANSE
20mg AdderallXR = 50mg VYVANSE
30mg AdderallXR = 70mg VYVANSE

Hope this helps

Vyvanse dosage question?

I am 14 years old and a freshman, I take 30mg of vyvanse daily at about 7 am, it usually lasts me until 12:00. Will upping the dosage make it last longer? My parents tell me that 30 mg should last 8 hours but it doesn't for me. Thanks in advance.

Vyvanse is the longest lasting stimulant being prescribed right now so its strange that you feel that way. If you up your dosage yourself you are going down a slippery slope: eventually, you will feel that say 50 mg of Vyvanse taken at 7am will only last you until 12. You should talk to the doctor that prescribed you Vyvanse to see what he has to say.

I've taken many stimulants including Vyvanse and I can tell you honestly that increasing your dosage does not make it last longer, it just comes on stronger.
