Dietary supplements and medications (prescription or over-the-counter) can be a dangerous combination. Many dietary supplement ingredients, especially herbs and botanicals, can interact with drugs or even other dietary supplements, which can either increase or decrease the effectiveness of your medications. In other words, you could be getting too much or too little of the medications that you need, putting your health at risk.
If you are taking or plan on taking a dietary supplement, inform your healthcare provider to make sure it’s safe to use with your medications. Even then, you should still take caution, as some dietary supplements contain ingredients not listed on the label.
The Food and Drug Administration (FDA) advises consumers to be aware of certain supplement/drug interactions and offers tips to stay safe. For more information, see the FDA’s Consumer Update. And for information about many known interactions, visit the Natural Medicines Comprehensive Database (NMCD).
Weight-loss (diet) prescription medications are generally not permitted, but it’s important to check your service’s policy for specific conditions that may exist.
