According to the Center for Science in the Public Interest CSPI , the amount of caffeine in food and drink varies widely among energy drinks, soft drinks, caffeinated waters, snack foods, chocolates and ice creams.
You could be looking at up to milligrams per ounce cup in some caffeinated counterparts. And, if you're not a fan of decaf coffee, you can often get a more modest amount of caffeine in options like green tea or iced black tea. CSPI states that caffeine is not wholly good or bad on its own, but if you consume high amounts of it, you can have issues beyond blood pressure, particularly when you try to cut down.
This can include withdrawal symptoms like headaches, irritability and fatigue. It's helpful to pay attention to how much caffeine is actually affecting you if you have high blood pressure, notes the Mayo Clinic. For example, check your blood pressure right before drinking a cup of brewed coffee, and then check twice more — once 30 minutes after, and again two hours after. If your blood pressure increases by 5 to 10 points on those second and third readings, May suggests that you consider cutting back or even eliminating caffeinated beverages altogether.
However, there was a slightly elevated risk associated with 1—3 cups a day. As coffee contains many different compounds aside from caffeine, other compounds could be responsible for its effects on blood pressure. However, a person could try switching to decaffeinated coffee to see whether their blood pressure decreases.

However, they concluded that a regular intake of up to milligrams of caffeine per day appears to be safe and may even be protective against heart rhythm disorders. The researchers cautioned, though, that if there is a clear association between arrhythmia episodes and caffeine, a person should not drink coffee.
Some alternatives to coffee contain caffeine, while others are naturally caffeine-free. People can try:. If someone experiences concerning symptoms when they drink coffee, they may wish to speak to a doctor.
Those who notice an increase in blood pressure should seek medical advice. Research suggests that people with high blood pressure can drink coffee as long as they are cautious. Regular coffee drinkers may build up a tolerance to the physiological effects of coffee, whereas those who drink it less often may experience an increase in their blood pressure. Coffee may be suitable for people with high blood pressure and could even have beneficial effects.
