Studies have shown that there are supplements that could interact with certain prescription medications. Millions of people take dietary supplements, some of which could be beneficial, while some might interfere with the effectiveness of medications. Those that take supplements are generally not aware that supplements, such as aloe vera, bitter orange, ginseng, kava, licorice root and melatonin might prevent the efficacy of medications for hypertension, diabetes, kidney disease and high blood pressure.
For instance, aloe vera, taken orally as a laxative might interact with medicines that treat diabetes, though safe when used on your skin. Bitter Orange, recommended for nausea or indigestion might accelerate heartbeat, thus elevating your blood pressure. Ginseng might interact with the anticoagulant, warfarin, including some antidepressant medications Kava, recommended for insomnia and anxiety might cause liver damage and hepatitis, as well as impair your driving ability. Licorice root, recommended for ulcers, bronchitis and sore throat, might elevate your blood pressure and cause heart problems. Melatonin, recommended for insomnia might interact with blood pressure medications, as well as cause bleeding when you are on a blood- thinner. While garlic is touted to be beneficial, it could act as a blood-thinner and cause bleeding.
There are a number of dietary supplements that might not be tested. While there are supplements that are highly recommended, there are those that have hidden dangers, such as the possibility of contamination. For instance, vitamin K, might block the effect of warfarin that could otherwise help prevent blood clots. Zinc, taken in excess, might cause nausea, vomiting, loss of appetite, stomach cramps, diarrhea and headaches, It could also interact with drugs, such as antibiotics and blood pressure medications.
