Faq for CAFFEINE - ORAL

Caffeine is a natural stimulant found in various plants, such as coffee beans, tea leaves, and cocoa beans. It is also a common ingredient in many beverages, foods, and medications.

Caffeine works by stimulating the central nervous system, blocking adenosine receptors in the brain. This helps in increasing alertness, reducing fatigue, and improving concentration.

Coffee, tea, energy drinks, soft drinks (sodas), chocolate, and some medications (like pain relievers and cold medicines) commonly contain caffeine.

According to the FDA, moderate caffeine consumption (up to 400 milligrams per day) is generally considered safe for most healthy adults. However, individual sensitivities and tolerance levels may vary.

Consumption of excessive caffeine can lead to side effects such as insomnia, restlessness, nervousness, increased heart rate, digestive issues, muscle tremors, and dependency or addiction.

While caffeine has a slight diuretic effect, moderate caffeine intake does not significantly contribute to dehydration. However, excessive consumption or consuming caffeine in the form of highly concentrated drinks may have a mild dehydrating effect.

It is generally recommended that children and teenagers limit their caffeine intake. The American Academy of Pediatrics suggests that adolescents should consume no more than 100 milligrams of caffeine per day from all sources.

Yes, caffeine can be addictive. Regular consumption of caffeine can lead to physical and psychological dependency, causing withdrawal symptoms like headaches, irritability, and fatigue when it is abruptly discontinued.

Moderate caffeine intake during pregnancy (up to 200-300 milligrams per day) is generally considered safe, but higher amounts may increase the risk of miscarriage or preterm birth. It is advisable to consult with a healthcare professional for specific recommendations.

Yes, caffeine can interact with certain medications, both prescription and over-the-counter. It may enhance or reduce the effects of certain drugs, so it is important to check with a healthcare professional or read medication labels for any warnings or precautions regarding caffeine consumption.
