Caffeine occurs naturally in certain plants, nuts, and seeds. It is a stimulant that increases some of the body's natural processes.
Manufacturers at times add it to some drinks and call these "energy drinks". There are many products that contain caffeine and it is not always apparent how much or what these ingredients are. Like with everything, taking too much caffeine can be harmful.     
Some of the typical side effects of caffeine can include:
  • feeling more awake or alert
  • feeling restless, anxious, or irritable
  • increased body temperature
  • dehydration
  • headache
  • faster breathing
  • faster heart rate
Symptoms of consuming too much caffeine can include:
  • very fast or irregular heartbeat
  • shakiness
  • feeling sick or vomiting
  • confusion
  • panic attack
If you think someone has taken too much caffeine, call the poison control center right away at

A 34 year old female called the poison center because she had recently started taking some "natural" diet pills to lose weight. She was complaining of feeling anxious and having palpitations. After consulting with one of our specialists it was recommended that she discontinue using the product to see if her symptoms disappeared.  Upon follow-up the following day, the patient reported that her symptoms had disappeared. The specialist recommended she discontinue the use of that product and recommended she consult with her physician before using any other related products.

Case #2
We received a call from a gentleman that was experiencing some symptoms after drinking his 3rd energy drink on the job. He began to feel light headed and his heart was racing. He explained that he had not slept well the night before and he had taken them to stay awake on the job. The specialist explained that since he was not a regular drinker, it was likely that these symptoms were related to having too much caffeine. It was recommended that he discontinue using the product and to refrain from any activities that required climbing or being in high altitudes and/working with any machinery and to call us back if the symptoms lasted longer than a few hours. Upon follow-up hours later, the patient was feeling better and was back to his regular duties at his jobsite.
