Can I take Amlodipine and Citalopram together?

Why this happens

Both medications have the potential to affect the 'QT interval' (the electrical timing of the heart). Citalopram is known to cause this effect, especially at higher doses, and amlodipine may occasionally contribute to this or change how the heart responds to electrical signals.

For most people, this combination is safe, but you should use caution. Ensure your doctor knows you are taking both. Seek medical help immediately if you feel a sudden fast or pounding heartbeat, severe dizziness, or if you faint. Your doctor may occasionally want to check your heart rhythm with an ECG (heart trace) or monitor your salt levels (electrolytes) through blood tests.

Heart rhythm disorders (Long QT syndrome)

Do not take citalopram if you have a history of abnormal heart rhythms or are taking other medicines that affect heart rhythm, as it can cause a life-threatening heart rhythm change.

Severe aortic stenosis

Amlodipine can cause a dangerous drop in blood pressure if you have a severely narrowed heart valve (aortic stenosis).

Trastornos hemorrágicos

Citalopram increases your risk of serious bleeding, especially if you are also taking aspirin, warfarin, or other blood-thinning medicines.

Grapefruit juice

Grapefruit juice can increase the concentration of amlodipine in your blood, which may make your blood pressure drop too low and increase the risk of side effects like headaches or swollen ankles. Avoid drinking large amounts of grapefruit juice while taking this medicine.

Alcohol

Drinking alcohol while taking these medicines can make you feel more sleepy or dizzy. It is best to stop drinking alcohol or keep your intake to a minimum until you see how the medicines affect you.
