Vyvanse to Adderall Conversion
When comparing medications in the same drug class, dosages that require a smaller amount to produce the same effect are generally considered more potent. In the case of Vyvanse and Adderall, it takes a smaller dosage of Adderall to generate the same effect as Vyvanse. The general guideline is that as the daily Vyvanse dose is increased by 10 mg, the total daily dose of Adderall is increased by 5 mg. It’s important to note many people take Adderall doses twice a day, while others take Vyvanse once a day.
For example, Vyvanse 30 mg is converted to Adderall 10mg and Vyvanse 70 mg is converted to Adderall 30 mg, because there are two more potent doses of Adderall per day and just one less potent but larger dose of Vyvanse.
However, someone using these medications should never take it upon themselves to change dosages, particularly between medications. This must be done under the direction of a licensed medical professional, who considers the person’s health and reaction to side effects, among other factors.
Adderall to Vyvanse Conversion
If someone is on a dose of Adderall and needs to switch to Vyvanse, the same general rule may be applied. For instance, Adderall 10 mg over the course of the day (two 5 mg doses) would be equivalent to one Vyvanse 30 mg dose per day.
Can You Take Vyvanse and Adderall Together?
There is no clinical benefit in taking these two medications together for ADHD. In the rare case that a person is suffering from both narcolepsy and binge eating disorder, a prescriber may use a stimulant for one condition and choose another type of drug for the other. For example, a physician may prescribe Vyvanse for binge eating disorder and pitolisant for narcolepsy.
Taking Vyvanse and Adderall together can also be dangerous, as taking two stimulants at the same time can increase the potential for harmful side effects.
