Coffee contains caffeine, a stimulant that may affect blood pressure in some individuals. However, research shows that this effect is usually short-lived and does not increase the risk of heart problems for most people.
This article explores how losartan works, how to take it, and foods and beverages that may affect how is works, including coffee.
What Is Losartan?
Losartan is a medication known as an angiotensin II receptor blocker (ARB) used to treat high blood pressure (hypertension). It works by blocking a substance in the body that causes blood vessels to tighten. Losartan allows blood vessels to relax, making it easier for the heart to pump blood throughout the body.
Losartan may be known by the brand name Cozaar. When combined with hydrochlorothiazide, losartan is known by the brand name Hyzaar. It is usually taken once or twice a day orally (by mouth).
Side Effects
Losartan may cause side effects. The most common side effects in people with hypertension include:
Upper respiratory infectionDizzinessStuffy noseBack pain
Some individuals also experience joint pain, muscle aches, vertigo (spinning sensation), nausea, vomiting, diarrhea, or headache. Talk to your healthcare provider about any side effects you may be experiencing.
Does Caffeine Raise Blood Pressure?
Several studies show that moderate caffeine consumption does not appear to increase blood pressure or lead to increased cardiovascular (heart) issues over the long term, even in individuals with hypertension. However, consuming caffeine can impact your blood pressure in the short term.
Short-term Effects
Drinking coffee may slightly increase blood pressure for up to three hours after consumption in people with hypertension. This could lead to cardiovascular problems if you have uncontrolled hypertension.
Individuals who do not usually consume caffeine may also experience a temporary increase in blood pressure after drinking a caffeinated product. However, this effect is typically short-lived.
Long-term Effects
Individuals who regularly consume coffee do not demonstrate the same increase in blood pressure as those who only drink coffee occasionally. This is likely because individuals who routinely consume caffeine develop a tolerance to its effects.
Importantly, long-term and regular consumption of moderate amounts of coffee is not associated with increased cardiovascular problems. The U.S. Food and Drug Administration (FDA) suggests that consuming up to 400 milligrams of caffeine (up to four or five cups of coffee) per day is likely safe for most adults.
It’s important to be aware of other foods and beverages that might contribute to this daily limit, including caffeinated sodas, chocolate, and tea. Everyone reacts to caffeine differently, and individual tolerance levels can vary.
What to Avoid When Taking Losartan
Most foods and beverages do not affect losartan. However, it is important to use caution with foods and medications that could affect your potassium levels, including:
Salt substitutes that use potassium Potassium supplements Other medications that increase serum potassium levels Water pills (diuretics) Lithium Medicines used to treat pain and arthritis called nonsteroidal anti-inflammatory drugs (NSAIDs), such as Advil, Motrin (ibuprofen) or Aleve (naproxen)
Be sure to speak with your healthcare provider before stopping or changing any medications, and let them know if you take any vitamins or herbal supplements.
Tips on Taking Losartan
Losartan may be taken with or without food. Keep this medication tightly sealed away from children and store it in a cool and dry location.
Be sure to take losartan exactly as prescribed. If you miss a dose, take it as soon as you remember. If it is almost time for your next dose, don’t take the missed dose. Just take the next dose at the regular time.
Losartan should be used as part of a comprehensive approach to hypertension management. Diet, exercise, and lifestyle modifications can also help reduce your blood pressure and improve overall health.
Summary
Losartan can be an important part of blood pressure treatment. This medication works by helping relax blood vessels so the heart doesn’t have to work as hard to pump blood. Losartan has a low risk of side effects, and it may be taken with or without food.
Most foods and beverages are fine to consume when taking losartan, including coffee. Extensive research shows that moderate, routine consumption of caffeinated products does not significantly affect blood pressure. However, always talk to your healthcare provider about what you consume, including other medications, supplements, and vitamins.
A Word From Verywell
The right approach to hypertension management will depend on your particular situation, including your past medical history and any other medications you may be taking. If you have concerns about caffeine intake and heart health, talk to your healthcare provider for guidance.
