Key Takeaways

  • Herbal supplements can change how your medicines work, sometimes causing serious health issues.
  • Before mixing herbs with medications, always talk to a healthcare provider for safety.
  • St. John’s Wort and other herbs like ginseng and garlic can interfere with the effectiveness of many prescription drugs.
  • Side effects from mixing herbs with medications can range from mild to very dangerous.
  • Use online tools and inform your healthcare provider about all the supplements and medications you're taking to avoid negative interactions.

Understanding Pharmacokinetic and Pharmacodynamic Interactions

 

Pharmacokinetic interactions happen when herbal supplements change how medications enter, break down, or leave your body. This can make drugs work too well or not enough. For example, St.

John's Wort speeds up the breakdown of many prescription drugs in the liver. This means your body might use up the medication too quickly and it won't have the intended effect.

Pharmacodynamic interactions occur when a herb directly affects what a drug does to your body. An herbal supplement could either increase or decrease a medication's effects. Ginseng, for instance, may lessen how well blood thinners like Coumadin work, raising the risk of blood clots.

Understanding these types of interactions helps avoid unexpected responses from combining herbs with prescription medications.

Risks of Interactions with Specific Herbal Supplements

 

Certain herbs can change how your medicines work. This can lead to unexpected problems with your health.

Black Cohosh 

Black cohosh is a plant many women use, hoping it will ease menopausal symptoms. Research shows this belief might not hold true. Studies using self-reported rating scales have found the herb doesn't significantly relieve these symptoms.

People also worry about its safety with prescription drugs. Even though no scientific reports prove black cohosh causes problems with other medicines, experts still urge caution, especially if someone takes medications that can hurt the liver.

This herb can come with side effects like headaches and upset stomachs. However, serious bad reactions are very rare. Doctors haven't found any major interactions between black cohosh and pharmacy medicines yet.

But they agree more studies are necessary to fully understand how safe and effective black cohosh is when mixed with other herbal supplements or medicine cabinet staples for managing health concerns or diseases.

Garlic

Garlic supplements might mess with how well some drugs work. For instance, they can reduce the effectiveness of saquinavir, a drug used to fight HIV infection. Eating small amounts of garlic in food is okay and usually doesn’t cause problems.

But taking lots of garlic as a supplement can lead to drug interactions.

Taking garlic in pill form can also cause serious side effects like uncontrolled bleeding. Studies have shown that garlic extract lowers the levels of drugs moved by P-gp, a protein that helps transport drugs across cells.

People using medicines for heart and blood vessel issues need to be extra careful about mixing them with garlic supplements.

Ginkgo Biloba

Ginkgo Biloba can raise the risk of bleeding. This happens especially when mixed with certain drugs and herbal supplements. Studies have found many interactions between Ginkgo Biloba, other medicines, and dietary supplements.

People who take anticoagulant drugs should be careful with Ginkgo Biloba because it might lead to bleeding episodes.

Taking Ginkgo Biloba comes with risks, like allergies or reactions with some medicines. Yet, its health perks are also recognized. Despite potential benefits, being aware of possible side effects and drug interactions is critical for anyone considering this supplement.

Ginseng (Asian)

Asian ginseng, also known as Panax, can cause problems when mixed with certain medications. It affects drugs like ACE inhibitors, which help lower high blood pressure. People taking these should be careful.

Ginseng has been linked to health issues including mood swings, allergies, heart and kidney problems, and even bleeding in sexual organs.

Mixing ginseng with the depression drug phenelzine might lead to headaches, shaking, and extreme happiness. Drinking coffee while using ginseng could make you too excited and upset your stomach.

Always talk to doctors before combining ginseng with other medicines or vitamins to avoid bad reactions.

Goldenseal

Goldenseal stops two big enzymes, CYP2D6 and various P450 enzymes. This can change how other drugs work in your body. If you mix goldenseal with blood thinners, you might get more bruises or bleed more easily.

Also, if you are pregnant or breastfeeding, stay away from goldenseal because it's not safe.

In many Chinese remedies, people use parts from the goldenseal plant that are rich in berberine. Berberine can mess with how your body handles other drugs. So, taking goldenseal while on certain medicines could cause problems.

Always talk to a healthcare provider before mixing goldenseal with your medication routine.

St. John's Wort

St. John's Wort can mess with a lot of medications. It changes how the body breaks down drugs in the liver. This means some medicines might not work as well or could cause more side effects.

For example, if taken with antidepressants, it can lead to too much serotonin in the brain. This is bad and can make you very sick.

This herb also affects drugs like digoxin for heart disease, warfarin that helps prevent blood clots, and birth control pills. If you mix St. John's Wort with these medicines, it could make them less effective or increase harmful effects.

Always talk to your health care provider before adding St. John's Wort to your routine, especially if you take other medications regularly.

The Dangers of Mixing Medications and Dietary Supplements

Mixing dietary supplements with medications can lead to serious, sometimes deadly outcomes. Drugs for HIV/AIDS and heart problems are especially risky when combined with natural medicines.

This mix can weaken a drug's effect or cause dangerous reactions in the body. For instance, certain herbal supplements might speed up how quickly the liver processes medication, reducing its effectiveness.

Herbal products like St. John’s Wort are known to interact poorly with many prescription drugs, such as anticoagulants and antiplatelet agents like aspirin. These interactions can either lessen the benefit of the medication or amplify adverse effects, leading to health complications.

With nearly 1500 known interactions between different drugs and nutritional aids causing varied harmful effects, it's clear that caution is crucial. Always talk to healthcare providers before adding any supplement to your routine if you're already taking other medications.

Tips for Safely Using Herbs with Medications

 
Herbal supplements can interact with medicines. Always talk to a doctor before mixing them. Here are some tips for using herbs safely with medications:

  1. Learn about your herbs and medicines. Use online tools like herb-drug interaction checkers to determine how your herbal supplements might react with your medications.
  2. Stick to the right amounts. Taking more than the suggested dose of an herb or medicine increases the risk of negative reactions.
  3. Share all information with your healthcare provider. Tell them about every supplement, over-the-counter medicine, and prescription drug you're taking.
  4. Watch for side effects. If you start feeling different after adding an herb to your routine, it could be a sign of an interaction.
  5. Schedule herbs and meds at different times. Spacing them out can reduce the chance they'll affect each other's performance.
  6. Read up on specific herbal risks. Some herbs, like St. John's Wort and ginkgo biloba, have well-known interactions with common drugs such as Lipitor or Warfarin.
  7. Avoid certain combinations entirely if advised by a professional. Some matches, like ginseng and heart medicines, are known to be risky.

By being careful and getting the right advice, you keep yourself safe while using both medicine and supplements together.
