Can I take Amlodipine, Valsartan and Atenolol together?

Why this happens

All three medicines work to lower blood pressure and reduce the workload on your heart, but they do it in different ways. Amlodipine relaxes blood vessels, valsartan blocks a hormone that narrows vessels, and atenolol slows the heart rate. When combined, their effects add together, which can sometimes be too powerful.

What you should do

You can take these together if they have been prescribed by your doctor, but you should monitor your blood pressure and heart rate regularly at home. Be careful when standing up quickly from a sitting or lying position. If you feel very dizzy, faint, or notice a very slow pulse, contact your doctor.

Important precautions

Pregnancy

You must not take valsartan if you are pregnant or planning to become pregnant, as it can cause serious harm or death to an unborn baby. Use effective contraception while taking it.

Asthma or COPD

Do not take atenolol if you have asthma, wheezing, or chronic obstructive pulmonary disease (COPD). It can cause a severe, potentially life-threatening narrowing of the airways.

Severe allergic reaction (Angioedema)

Seek immediate medical help if you experience swelling of the face, lips, tongue, or throat, as these medicines can cause a rare but serious allergic reaction called angioedema.

Food and drink warnings

Alcohol

Drinking alcohol while taking these blood pressure medicines can cause an additive effect, making you feel dizzy, lightheaded, or faint, especially when standing up. It is best to keep alcohol intake within recommended limits and see how the medicine affects you first.

Grapefruit juice

Grapefruit juice can increase the amount of amlodipine in your blood, which may cause your blood pressure to drop too low and increase the risk of side effects like headaches or swollen ankles. Avoid drinking large amounts of grapefruit juice.

Orange Juice and Apple Juice

Drinking large amounts of orange or apple juice may reduce the amount of atenolol absorbed by your body, potentially making it less effective. It is best to avoid drinking large quantities of these juices at the same time as taking your tablet.

Salt substitutes (Potassium-based)

Valsartan can increase the levels of potassium in your blood. Using salt substitutes that contain potassium (such as Lo-Salt) can lead to dangerously high potassium levels. Check with your pharmacist before using these products.
