Avoid drinking caffeinated beverages, including coffee, tea and cola; or caffeine-containing foods, like chocolate, to reduce the risk of interaction, advises Drugs.com. Discuss Vyvanse use, interactions and side effects thoroughly with your health care provider.
Gastrointestinal Effects
Vyvanse may cause gastrointestinal side effects in some people. Abdominal pain, nausea, vomiting and lack of appetite may occur. University of Maryland Medical Center states that caffeine may stimulate gastrointestinal upset by increasing stomach acid content. Combined, caffeine and Vyvanse may increase the severity of gastrointestinal effects, according to Kaiser Permanente, which suggests limited caffeine consumption while taking Vyvanse to reduce side effects.
Cardiovascular Effects
Vyvanse acts as a stimulant and may raise heart rate and blood pressure, leading to a risk of sudden heart attack or stroke, according to Drugs.com. You may experience increased pulse, heart palpitations or increased blood pressure while using the medication, which may worsen if you also consume caffeine. Drugs.com warns that you should seek medical attention if you experience a fast or irregular heart beat while taking Vyvanse, to prevent possible complications.
Central Nervous Effects
Some people experience increased stimulation to the central nervous system while taking Vyvanse, which may become worse if caffeine is consumed. Vyvanse stimulates areas of the central nervous system to calm hyperactivity and increase attention span, according to Vyvanse.com. Some people, however, may notice an increase in nervousness or restlessness while taking Vyvanse. Additional symptoms include insomnia, irritability or nervousness.
