Caffeine as a medication

Caffeine is sometimes used in combination with medicines to increase their effectiveness. Some of those medications are ergotamine in the treatment of migraine and cluster headaches, or with certain pain relievers such as Aspirin or acetaminophen.
Not only that, but for several years now it has also been used to overcome the drowsiness caused by antihistamines. Breathing problems in premature infants are sometimes treated with caffeine, which is available only by prescription in many countries.

Caffeine and addiction

Coffee has been heavily criticized for the fact that its caffeine content is addictive and unhealthy. However, most experts now believe that if you drink coffee with moderation, it can actually be beneficial. Coffee drinkers do not require increasing amounts of caffeine over prolonged periods of time (characteristics of addictive substances) and they can moderate or change their consumption with no difficulty. The caffeine contained in coffee will give you a significant boost of energy, provide you with an increase in performance for more tasks and also help you stay awake during drawn out tasks such as long distance driving. Other group of experts are saying that caffeine is definitely addictive because there are some serious withdrawal symptoms.
