Can I take Atenolol and Ramipril together?

Why this happens

Both medicines work to lower blood pressure but in different ways: atenolol is a beta-blocker that slows the heart rate, while ramipril is an ACE inhibitor that relaxes blood vessels. When used together, their effects add up (an additive effect). Both can also impact how the kidneys filter blood and manage potassium levels.

What you should do

It is very common for doctors to prescribe these two medicines together, but you should be monitored closely. When starting this combination, take your first dose at bedtime to avoid dizziness. Stand up slowly from a sitting or lying position. Your doctor will likely perform regular blood tests to check your kidney function and potassium levels. If you feel severely dizzy or faint, contact your GP.

Important precautions

Asthma or COPD

Do not take atenolol if you have asthma or a history of wheezing. It can cause severe narrowing of the airways, making it very difficult to breathe.

Pregnancy

Do not take ramipril if you are pregnant or planning to become pregnant. It can cause serious injury or death to an unborn baby, particularly if used in the second and third trimesters.

Angioedema (Swelling) - ramipril

Seek emergency medical help immediately if you experience swelling of the face, lips, tongue, or throat. This is a rare but life-threatening allergic reaction specific to this type of medicine.

Food and drink warnings

Alcohol

Drinking alcohol can increase the blood pressure-lowering effect of these medicines, which may make you feel dizzy, lightheaded, or faint, especially when you first start taking them or when your dose is increased. It is best to keep your alcohol intake within recommended limits and see how the medicine affects you before drinking.

Salt substitutes (Potassium-rich)

Ramipril can increase the levels of potassium in your blood. Many salt substitutes (such as Lo-Salt) contain potassium chloride instead of sodium. Using these while taking ramipril can cause your potassium levels to become dangerously high. Check with your pharmacist before using salt substitutes.
