Unknown to most people is the fact that everyday foods and Herbal supplements can and do interact with popular prescription medications. I became interested while talking to my Pharmacist that my son couldn’t take decongestant cold medications with his heart medication. Well, I knew about interactions between two drugs, but when the Pharmacist told me he couldn’t have grapefruit juice, I was stunned. Seems that grapefruit juice increases the blood concentrations of the drug. Basically that means that it greatly enhances the effects of the drug which could result in an overdose of the medication. This is everyday grapefruit juice! It got me wondering about other everyday foods and Herbs we take. Below are a few foods and Herbs that have an effect on your medications.

This list is a basic guide, and is by no means the meant to replace your Doctor or Pharmacist. Consult with them about any prescriptions you are taking and the foods and Herbs that will interact with them. Although I have taken this information from a handout from a local Hospital, Use this information at your own risk. Again, I am not a Doctor or Pharmacist, and I have had NO medical training, so please consult with yours for more information.

People usually ask if Herbal supplements change the way their prescription drugs work. The answer is YES! Some medications should never be taken with Herbal supplements. Some can cause unwanted side effects or cause the medication to stop working to their full effect.

Another misconception about supplements is that they are completely safe because they are natural. Yes, they may be from plants, but they are not natural to your body. Herbal supplements are not tested or inspected like prescription drugs are tested, so the supplements vary in quality and strength from pill to pill and bottle to bottle.

Just like supplements, foods can change the way your body responds to medications. One example is grapefruits and grapefruit juice. Many people aren’t aware that grapefruit juice can increase the drug levels of certain medications. An increase in the levels will also increase the side effects of the drug.

Things to Remember

1. Herbal supplements and foods can change the way your medications work.

2. Tell your caregiver what Herbal supplements you take and what foods you eat often.

3. Ask your Doctor or Pharmacist what Herbal supplements or foods will interact with your medications.

4. Always talk with your Doctor or Pharmacist FIRST before taking any Herbal supplements.

5 Responses to Interactions between Medications, Herbal supplements and common foods

  1. Stephen Davis says:

    What a lot of people don’t realize is that herbal supplements are drugs themselves. They were used as drugs before pharmaceutical drugs became common. It is natural but a lot of our drugs are based on herbal supplements.

  2. So glad you posted this article. Many people think just just because its a natural herbal supplement, that it’s safe for them. People need to do more research – especially if they are taking ANY kind of prescription meds. Thanks again,

    • Dwayne says:

      I agree. The one thing that shocks most people is how grapefruit affects the potency of most medications. Thanks for stopping by.

  3. This is really an amazing analysis on medications, supplements and common foods. It can be used as a diet guide. Thanks a lot for sharing.
