Avoid using herbal supplements if :
- You're taking prescription or over-the-counter (OTC) medications. Some herbs can cause serious side effects when mixed with prescription and OTC drugs such as aspirin, blood thinners or blood pressure medications. Talk to your doctor about possible interactions.
- A proven medical treatment is available for your medical condition. A traditional medication with an established record for safety and effectiveness will generally be less likely to result in adverse side effects.
- You're pregnant or breast-feeding. As a general rule, don't take any medications — prescription, OTC or herbal — when you're pregnant or breast-feeding unless your doctor approves. Medications that may be safe for you as an adult may be harmful to your fetus or your breast-feeding infant.
- You're having surgery. Many herbal supplements can affect the success of surgery. Some may decrease the effectiveness of anesthetics or cause dangerous complications, such as bleeding or high blood pressure. Tell your doctor about any herbs you're taking or considering taking as soon as you know you need surgery.
- You're younger than 18 or older than 65. Older adults may metabolize medications differently. And few herbal supplements have been tested on children or have established safe doses for children.
