The quinolone antibiotics may instead increase the absorption of caffeine: in all these cases it is therefore good to seek medical advice before consuming this drink. Coffee is also contraindicated if you suffer from hyperthyroidism and glaucoma or medical conditions in the intestine, stomach, liver, heart, kidney, pancreas, or nervous system.

You can also prepare it at home: coffee machines can be purchased at appliance stores, and specialty shops as well as larger supermarkets sell all types of coffee blends.
