Assessment and Plan:
- Coffee contains caffeine, a substance which may result in adverse reactions and interactions:
- Be aware that caffeine is classified as a methylxanthine and stimulant which may cause indigestion, palpitations (rapid heart beat), tremor, headache, diuretic effect and sleep difficulty.
- Caffeine should be avoided when taking the medications theophylline, aminophylline and pentoxyfylline which may potentiate (increase) the effects of these drugs.
- Caffeine may increase risk of premature death in patients with hypertension, cardiovascular disease, and stroke.
- Caffeine consumption increases calcium excretion in the urine and may increase the risk of kidney stones but other research shows a lower risk, so this is unclear.
- Excessive caffeine in supplements may cause stroke.
- High caffeine intake may result in hypokalemia.
