Agitation caffeine

False. Tea, coffee and cola all contain caffeine, a mild stimulant drug. In small quantities it provides a refreshing increase in energy levels in larger quantities it can lead to headaches, anxiety, agitation, tremors and insomnia. In extreme cases it has been known to cause death. [Pg.20]

Caffeine is the most widely consumed stimulant drug in the world. It occurs naturally in coffee, tea, and the cola nut and is added to many soft drinks. Many of us consume coffee and soft drinks because of the desirable stimulatory effects produced by caffeine many of us have consumed too much caffeine and felt the consequences. The undesirable effects of caffeine, the agitation, the inability to concentrate, the mild tremors, and the general unpleasantness, are a form of neurotoxicity. Literally your brain, and more specifically, the adenosine receptors in your brain, has too much caffeine. These effects are a reversible form of neurotoxicity. Fortunately, we metabolize caffeine quickly and the undesirable effects end. By experience we have learned how to moderate our caffeine consumption to avoid the unpleasant side effects. A great deal of money is made from the neuroactive and physiological effects of caffeine. You can learn more about this fascinating drug in the chapter on caffeine. [Pg.186]

The symptoms of jitters, insomnia, tremors, and agitation are common in those consuming caffeine and in those with depression or the other illnesses for which these drugs are prescribed. Combining caffeine with antidepressants may exaggerate the symptoms and make it difficult for the physician to arrive at an accurate diagnosis or evaluate the drug s effectiveness. [Pg.58]

Adverse effects Moderate doses of caffeine cause insomnia, anxiety, and agitation. A high dosage is required to show toxicity, which is manifested by emesis and convulsions. The lethal dose is about 10 g for caffeine (about 100 cups of coffee), which induces cardiac arrhythmias death from caffeine is thus highly unlikely. Lethargy, irritability, and headache occur in users who have routinely consumed more than 600 mg of caffeine per day (roughly 6 cups of coffee/day) and then suddenly stop. [Pg.111]

In general, over 250 mg (especially amounts over 500 mg) of caffeine per day can cause or contribute to psychiatric symptoms, especially anxiety, irritability, sleep disturbance, and agitation. Figure 4-B provides a guideline for a caffeine history— which should be done on every person being evaluated. [Pg.52]

Consuming more than 1,000 mg of caffeine a day increases the risk of experiencing even more severe toxic symptoms, including muscle txvitching, rambling flow of thought and speech, cardiac arrhythmia, periods of inexhaustibility, and psychomotor agitation (American Psychiatric Association, 1987). Other symptoms that have... [Pg.193]

Caffeine in guarana (Paullinia cupana), mate (Ilex paraguariensis), or concentrated green tea (Camelia sinensis) elicits a wide range of excitatory symptoms, particularly if it is present in excess. These plant products are frequently present in slimming preparations, and consumers should be aware of their potential to cause palpitations, sweating, insomnia, restlessness, agitations, tremors, headache, polydipsia and polyuria (DeSmet, 2004 Elvin-Lewis, 2001). [Pg.264]

A cup of coffee contains 100-150 mg of caffeine, tea has 1/3 as much... [Pg.653]

Caffeinism" refers to the increase of symptoms such as nervousness, agitation, headaches, insomnia, and irritability in a person taking birth control pills. [Pg.9]

The specificity of the MIP will be evaluated from competitive binding assays, as follows. Based on the [PJso (Img polymer per mL), a 10 mg/mL stock suspension (5 mL) is prepared in binding solvent. Keep the polymer in suspension by agitating the mixture with a small magnetic stirrer. Prepare competitor solutions containing 100 and 1 pg/mL of each theophylline, caffeine, or theobromine in binding solvent. Pipette these stock solutions into Eppendorf tubes according to the scheme in Table 8 (see pg. 46). [Pg.44]
