At an increased risk of thrombosis, blood thinning drugs are prescribed. These include warfarin and heparin. Caffeine can increase the concentration of such drugs in the blood and enhance their effect. As a result, the risk of bleeding and hematomas increases.
Melatonin
This is a hormone that begins to be produced in the dark and signals the body that it is time to sleep. It is prescribed to treat sleep disorders.
Caffeine works in different ways: it stimulates wakefulness, prevents sleep, and reduces melatonin levels. If you drink coffee at the same time as taking the hormone, the expected effect will be weaker.
Diabetes medications
Caffeine can increase blood sugar and insulin levels. This makes it harder to control the disease and increases the risk of complications. Some people experience such fluctuations even after one or two cups of coffee.
