Can I take Amlodipine and Ginseng together?

Drug interaction guide

Taking ginseng while on amlodipine may cause your blood pressure to drop lower than intended, or it could potentially make the amlodipine less effective. Some people experience symptoms like dizziness or light headedness, while others may find their blood pressure readings become less stable.

Why this happens

Ginseng has complex effects on the body. It can act as a mild diuretic (water pill) and has its own blood-pressure-lowering properties, which can add to the effect of amlodipine. However, some types of ginseng may also interfere with how the liver processes amlodipine (via the CYP3A4 enzyme), potentially changing the amount of medicine in your bloodstream.

You should speak with your doctor or pharmacist before combining these two. If you decide to take them together, monitor your blood pressure regularly at home. Seek medical advice if you feel dizzy, faint, or notice significant changes in your blood pressure readings.

High blood pressure (Hypertension)

Ginseng can increase blood pressure and may counteract the effects of amlodipine, making your blood pressure harder to control.

Diabetes

Ginseng can lower blood sugar levels. If you take medication for diabetes, using ginseng may increase the risk of your blood sugar dropping too low (hypoglycaemia).

Bleeding disorders or use of blood thinners (e.g. warfarin)

Ginseng can interfere with blood clotting and may increase the risk of bleeding, especially if you are taking anticoagulant or antiplatelet medications.

Grapefruit juice

Grapefruit juice can increase the amount of amlodipine in your blood, which may lower your blood pressure too much. While the effect is usually small, it is best to avoid drinking large amounts of grapefruit juice while taking this medicine.

Alcohol

Ginseng may speed up the way your body breaks down alcohol. This could potentially change how alcohol affects you, though the clinical significance is not fully established. Use caution if combining the two.

Caffeine

Ginseng can have a stimulant effect. Combining it with caffeine (found in coffee, tea, and energy drinks) may increase the risk of side effects like a racing heart, nervousness, or trouble sleeping.
