Re: What vitamins shoud I take with adderall IR to increase effect. Four hour efficacy is what you can expect from an instant release stimulant med. I don't believe that there is any way to extend this effect, as it's based on the amount of time it takes your body to metabolize the medication, and slowing your metabolism isn't generally. Choosing the best time to take Adderall is critical. According to Drugs.com, Adderall can cause a number of side effects, including restlessness, dizziness, diarrhea, insomnia and sometimes uneven heartbeats and hallucinations Taking the medication at the right time and as indicated by your doctor will reduce the risk of experiencing side effects.
Adderall -- a brand of amphetamine salts -- is a central nervous stimulant, or CNS. It is used in the treatment of attention deficit hyperactivity disorder, also known as ADHD. Caffeine is a naturally occurring substance found in a variety of plants, such as coca pod, cola nut and guarana. It is also in sodas, coffee, tea, chocolate and energy drinks. It, too, is considered a central nervous system stimulant, although a mild one. Adding two stimulant drugs together results in a more pronounced stimulation of your CNS. Therefore, taking caffeine with Adderall primarily makes potential side effects more severe.
