Can I take Doxadura and Ginseng together?

Why this happens

Doxazosin works by relaxing blood vessels to lower blood pressure. Some types of ginseng (particularly Panax ginseng) have been shown to have their own blood-pressure-lowering effects. When used together, these effects can add up, causing an 'additive' effect that lowers blood pressure more than expected.

What you should do

Use caution if combining these two. It is best to monitor your blood pressure regularly at home. If you feel dizzy, shaky, or faint, sit or lie down immediately. Speak to your doctor or pharmacist before starting ginseng to ensure it is appropriate for your specific health needs.

Important precautions

First-dose hypotension

Doxadura can cause a sudden drop in blood pressure, especially after the very first dose. This may make you feel dizzy or faint when standing up. It is recommended to take your first dose at bedtime to avoid falls.

Cataract surgery

If you are due to have eye surgery for cataracts, you must tell your surgeon you are taking Doxadura. It can cause a complication called 'Floppy Iris Syndrome' which the surgeon needs to prepare for.

Diabetes

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

Surgery

Ginseng can increase the risk of bleeding and may interfere with blood pressure control during surgery. You must stop taking it at least two weeks before any scheduled operation.

Food and drink warnings

Alcohol

It is best to avoid or strictly limit alcohol while taking Doxadura. Alcohol can increase the blood-pressure-lowering effect of this medicine, which may make you feel dizzy, lightheaded, or faint, especially when standing up.

It is best to avoid or strictly limit alcohol when taking ginseng. Ginseng may speed up the rate at which your body breaks down alcohol, but it can also interfere with how alcohol affects your central nervous system.

Caffeine

You should limit your intake of caffeine (found in coffee, tea, and energy drinks) while taking ginseng. Both substances act as stimulants; combining them can lead to increased heart rate, high blood pressure, nervousness, and difficulty sleeping.

Foods high in Vitamin K (e.g. leafy greens)

Ginseng may interfere with the way the body processes Vitamin K and can reduce the effectiveness of blood-thinning medications like warfarin. If you take blood thinners, consult your doctor before using ginseng.
