Can I take Amlodipine and Sotalol together?

Why this happens

Both medicines work to lower blood pressure and affect the heart, but in different ways. Amlodipine relaxes blood vessels, while sotalol slows the heart rate and reduces the force of the heart's contractions. When used together, their effects add up, which can lead to an excessively slow heart rate (bradycardia) or very low blood pressure (hypotension).

You can take these medicines together, but your doctor should monitor you closely, especially when starting the combination or changing doses. Monitor your blood pressure and pulse at home if possible. If you feel very dizzy, faint, or notice a very slow pulse, contact your doctor. Rise slowly from a sitting or lying position to prevent falls.

Asthma or COPD

You must not take sotalol if you have asthma or chronic obstructive pulmonary disease (COPD). It can cause severe, life-threatening narrowing of the airways.

Heart Rhythm Disorders (QT Prolongation)

Sotalol can cause a specific dangerous heart rhythm problem. You must have regular ECGs and blood tests to check your potassium and magnesium levels, as low levels increase this risk.

Liver Disease

If you have liver problems, amlodipine stays in your body much longer. Your doctor must monitor you closely and use a lower starting dose to avoid severe low blood pressure.

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.

Alcohol

Alcohol can enhance the blood-pressure-lowering effect of sotalol, which may make you feel dizzy or lightheaded, especially when standing up. It is best to keep your alcohol intake within recommended limits.
