Can I take Doxadura and Garlic supplements together?

Varför detta händer

Doxadura is an alpha-blocker used to lower blood pressure and treat prostate issues. Garlic supplements have natural blood-pressure-lowering properties. When used together, their effects can add up (an additive effect), causing an excessive drop in blood pressure.

Use caution when combining these two. If you decide to take garlic supplements, monitor your blood pressure regularly. Be careful when standing up quickly. If you feel very dizzy or faint, stop the supplement and speak to your GP or pharmacist. It is best to inform your doctor before starting any new herbal supplements while on blood pressure medication.

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.

Kirurgi

Both garlic supplements and Doxadura can increase the risk of bleeding or affect blood pressure during surgery. You must stop taking garlic supplements at least two weeks before any planned surgical or dental procedure.

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.

Alkohol

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.
