Coffee/caffeine products have been used for many years by some people
to relieve asthma and by a very small subpopulation with the ADHD/ADD
syndrome to relieve symptoms of ADHD/ADD/Hyperactivity. Many FDA
products with an active ingredient of caffeine caution (partial listing
only): For occasional use only. If fatigue or drowsiness persists or
continues to occur, consult a doctor. Limit the use of caffeine-
containing medications, foods, or beverages while taking this product
because too much caffeine may cause nervousness, irritability,
sleeplessness and, occasionally, rapid heart beat.
