The potential of drug-herbal interaction among patients with chronic diseases in Saudi Arabia

Abstract Aims This study aimed to estimate the prevalence of the potential drug-herbal interaction among patients with chronic diseases in Al-Kharj, Saudi Arabia and to explore factors associated with the potential of drug-herbal interaction. Method A cross-sectional study was conducted through interview-based questionnaire at outpatient clinics in Al-Kharj. The study included patients with chronic diseases who used herbal products. Results This study included 336 patients in total. The mean age of participants was 52.4±12.0 years, and their most-used medications were metformin, atorvastatin, and aspirin, while their most-used herbs were ginger (74.7%), mint (72%), and cumin (66.7%). In 310 out of 336 (92.26%) cases, at least one potential drug-herbal interaction was found, and most of these interactions (84%) were moderate. Conclusion A substantial percentage of potential drug-herbal interactions were found among patients with chronic diseases. Healthcare providers are encouraged to discuss the safety and efficacy of herbal products with their patients.
