Herbal medications in the perioperative orthopedic surgery patient

The impact of complementary and alternative treatment modalities on the care of orthopaedic patients

The use of complementary and alternative medicine is widespread and popular with the lay public. Although prevalence of use varies among specific patient populations, complementary and alternative medicine, in particular herbal remedies, are widely marketed and used by orthopaedic patients. Herbal supplements can have a negative impact on the perioperative period and may interact with conventional medicines used to manage chronic conditions. Physician-patient communication often does not include the subject of alternative medicines, leading to underreporting of use. Orthopaedic surgeons should adopt methods to routinely elicit from their patients the use of complementary and alternative medicine and should monitor and counsel patients on potential side effects and drug-herb interactions. Preoperative instructions should include cessation of the use of herbal supplements.

The potential impact of the use of homeopathic and herbal remedies on monitoring the safety of prescription products

The purpose of this paper is to explore the possibility that adverse reactions and drug interactions arising from the use of homeopathic and herbal medicines could lead to confusion when adverse reactions to conventional medicines are reported. An extensive literature review was conducted on the occurrence of adverse reactions and drug interactions following the use of homeopathic or herbal remedies, and the potential for these to confound adverse event reporting to conventional medicines considered. The survey demonstrates the potential for herbal remedies and homeopathic products, to produce adverse drug reactions or drug interactions, and shows the scope for potential for confusion with those arising from conventional medicines. There is a need for greater awareness that adverse reactions apparently due to a conventional medicine, might in reality be due to a herbal medicine or a drug interaction between a herbal medicine and a conventional drug, particularly when a health professional is unaware of the extent of a patient's self-medication with alternative therapies.
