A caffeine overdose refers to a condition whereby an individual of caffeine takes high concentrations of this product in the body which causes harm to the body system. Caffeine is a naturally occurring stimulant, found in beverages, including coffee, tea, energy drinks and chocolate, as well as in many prescription drugs. In moderation, caffeine is not a problem; however, its toxicity becomes possible due to its stimulating effect on the CNS and CV system. Symptoms of acute caffeine poisoning includes anxiety, insomnia, tachycardia, restlessness, tremors, nausea, vomiting and, rarely, seizures and arrhythmias. The toxicity of caffeine is relatively mild in the normal range and there are toxic effects which are normally found at doses greater than 400-500 mg in adults.
Epidemiology
Caffeine toxicity incidents are relatively common and is most seen in children and young adults who may take energy drinks, supplements or caffeine-containing beverages such as coffee in large quantities. Overdose cases in emergency departments have occurred with caffeine, mainly among teenagers and young adults linked to energy drinks in recent years. Caffeine toxicity is one of the most common toxicological problems in America, and the cases have been on the rise in the past 10 years. Emergency department visits related to energy drinks have also risen sharply with SAMHSA pointing to figures rising by approximately 10 times between 2005; A study done on 1073 adults found that between 2007 and 2011 the incidence of energy drink related visits to the emergency rooms had doubled.
Anatomy
Pathophysiology
Caffeine toxicity is a condition which arises from consumption of large quantities of caffeine such that it causes disturbance of normal body functions; mostly affects the nervous system, the cardiovascular system and the metabolic system. Caffeine acts as a CNS stimulant by inhibiting adenosine receptors that bring about a release of transmitters such as dopamine, norepinephrine and glutamate. This results in increased sensitivity, faster pulse rate and raised blood pressure. In toxic level caffeine can stimulate these systems and the person presents symptoms such as restlessness, anxiety, tremors, increased heart rate, high blood pressure, seizures and arrhythmia. It also increases catecholamine release, cortisol and glucose levels being elevated leading to metabolic disturbances. At high-intensity doses, caffeine concentration overpowers the body’s metabolism of caffeine and exposes the heart and nervous system to dangerous effects, and at certain times, lethal.
Etiology
Caffeine toxicity arises from the use of large amounts of caffeine, mainly from coffee, tea, soft drinks and meals or caffeinated supplements. The etiology includes both high concentrations within a short span and an accumulation from sustained excessive quantities. This can overload its metabolism of this substance’s stimulating effects, which present as palpitations, anxiety, tremors, nausea, seizures and arrhythmia among other signs. There are genetic factors, liver damage and other products that do not let caffeine metabolize at an optimal rate.
Genetics
Prognostic Factors
Though there are few instances of caffeine poisoning reported, prognosis eminently depends upon how early treatment is implemented. In cases of serious toxicity, prognosis depends on the extent of caffeine elimination from the patient’s bloodstream using hemodialysis or intralipid therapy.
Clinical History
Age Group:
Young Children and Adolescents: Children and teenagers are highly sensitive to caffeine due to their smaller body sizes and relatively low tolerance levels. The toxicity of caffeine occurs among younger children at such low doses as 1-2 mg of caffeine per kg of body weight. Products with high content of caffeine, such as energy drinks or sodas, can be dangerous for them sometimes even at moderate doses.
Teenagers and Young Adults: Adolescents take many products containing caffeine include energy drinks, coffee and caffeinated sodas and this leads to toxicity most of the time. This age group is susceptible to consuming a lot of caffeine because of energy drinks and coffee, they take.

Acuity of presentation
Mild Toxicity (20-200 mg/kg body weight): Symptoms are often mild and can appear gradually. These may include:
Tachycardia (elevated heart rate)
Irritability
Nausea
Mild headache
Nervousness
Moderate Toxicity (200-400 mg/kg): Symptoms may intensify, typically requiring medical attention but not intensive care. Symptoms can include:

Treatment Paradigm
Mild to Moderate
Toxicity Symptoms: Anxiety, insomnia, muscle twitching, tachycardia, vomiting, and headaches.
Management:
Discontinue caffeine intake: The first action that the patient needs to take regarding moderation of caffeine intake is to cease any further intake of the stimulant.
Hydration: Give enough water so that caffeine may be washed out of the system by acting as a diluting agent.
Symptom management:
Betablockers include propranolol which may be used for managing tachycardia.
Lorazepam and other benzodiazepines may be prescribed for anxiety or tremors.
Observation: By doing this the patient should be observed for worsening of the above symptoms or development of complications. Severe Toxicity Symptoms:
Life-threatening Symptoms: Seizures, arrhythmias, hypotension, metabolic acidosis and coma.
Management:
Activated charcoal: If the patient has consumed caffeine within the previous 1-2 hours, administer the activated charcoal to decrease the amount that is absorbed.
Supportive care: This involves giving fluids intravenously to correct dehydration and balance of electrolyte loss.
Seizure management: First-line anticonvulsive therapy involves the use of benzodiazepines such diazepam, lorazepam.
In case of seizures, resistant to other drugs, one should use barbiturates or propofol.
Arrhythmias: Lidocaine and amiodarone for ventricular arrhythmias. Magnesium sulphate may be used in some forms of arrhythmias. Hemodialysis: For serious toxicity cases, or if the measured caffeine concentration is high, renal replacement therapy in the form of hemodialysis may be used in removing caffeine from the body.
Close monitoring: To require monitoring with intensive care unit (ICU) care, with evaluations of vital signs, ECG, and laboratory tests.
Reduce Noise and Stimulation: Caffeine has been shown to cause anxiety and nervousness so keeping the environment as non-stimulating as possible will also reduce environmental stressors.
Dim the Lights: The different sources of light might cause stress to the individual, hence, turning down the intensity of the light to make the individual comfortable.
Ensure Proper Hydration:
Provide Water or Electrolyte Solutions: Even though caffeine is a mild diuretic it is capable of leading to dehydration. In terms, of comfort, the use of water or an electrolyte solution will be used in the further rehydration of the person.
Maintain Comfort with Temperature Control: A well-ventilated room will also benefit the lungs if the person becomes anxious or having tachypnea.
Limit Physical Activity:
Encourage Rest and Relaxation: Any form of exercise prolongs the duration of time one will spend with elevated heart rate; this especially worsens caffeine related effects.
Supportive Monitoring Environment:
Monitor Vital Signs: If possible, have access to a device for monitoring heart rate and blood pressure, especially if the individual has ingested a large amount of caffeine. Severe cases may require medical attention.
Use of Activated Charcoal in treating caffeine toxicity
Activated Charcoal: Given to absorb caffeine if the poisoning is recognized early after consumption. This can indeed actually allow the prevention of further absorption of caffeine from the stomach.
Role of Benzodiazepines in treating caffeine toxicity
Diazepam, Lorazepam: These may be used in control of symptoms such as agitated state, anxiety, and convulsions caused by excessive consumption of caffeine.

Initial Phase (Mild to Moderate Toxicity):
Assessment: Check serum caffeine levels if possible.
Symptom Management: Physical, psychosocial and emotional care (Giving fluids or medications intended to manage nausea and vomiting).
Monitor: Vital signs (heart rate, blood pressure), and ECG for arrhythmias.
Gastric Decontamination: Activated charcoal may be used if the ingestion was recent (within 1–2 hours).
Intermediate Phase (Moderate to Severe Toxicity): IV Fluids: Rehydrate the patient and assist with detoxification. Benzodiazepines: Use for agitation or seizure activity. Monitor: Continue ECG monitoring for arrhythmias and titrate medications accordingly. Activated Charcoal: Continue if ingested recently and in a high dose. Severe Toxicity (Life-Threatening Toxicity): Hemodialysis: Should be considered for severe toxicity as manifested by very elevated caffeine levels (e.g., >100 mg/L) or in cases of renal failure. Symptomatic Treatment: For arrhythmias, seizure activity, or other life-threatening complications. Close monitoring: With continuous monitoring of ECG and blood pressure and organ function.
