Apple cider vinegar (ACV) is celebrated for its numerous health benefits, from aiding digestion to helping with weight loss and balancing blood sugar.
However, while ACV can be beneficial for many, it can also pose serious health risks when combined with certain medications.
Due to its acidic nature and powerful effects on the body, apple cider vinegar can interact with specific medications, potentially leading to adverse reactions.
If you’re taking any of the following medications, you must talk to your healthcare provider before incorporating ACV into your routine.
1. Diabetes Medications
Apple cider vinegar is known to help control blood sugar levels, which is one of the reasons people with diabetes may be interested in using it. However, if you’re already on blood sugar-lowering medications, ACV could amplify their effects and lead to dangerously low blood sugar (hypoglycemia).
Medications That Could Interact:
- Insulin: People who use insulin injections must closely monitor their blood sugar levels if they decide to use ACV. The combination of insulin and ACV could cause blood sugar levels to plummet, leading to hypoglycemia.
- Metformin: This common diabetes medication can lower blood sugar; adding ACV may cause it to drop too low.
What to Do:
If you have diabetes and are interested in using apple cider vinegar, consult with your doctor. They may advise against it or help you adjust your dosage to avoid potential complications.
2. Diuretics (Water Pills)
Diuretics, often called “water pills,” are used to help remove excess water and salt from the body. Apple cider vinegar, however, is known to have a mild diuretic effect as well.
When combined with diuretics, it can lead to a significant loss of potassium, resulting in hypokalemia (low potassium levels). Low potassium can cause muscle weakness, cramps, fatigue, and even heart problems in severe cases.
Medications That Could Interact:
- Furosemide (Lasix)
- Chlorothiazide
- Hydrochlorothiazide
- Bumetanide
What to Do:
If you’re on a diuretic, speak with your healthcare provider before using ACV to avoid electrolyte imbalances.
3. Digoxin (Lanoxin)
Digoxin is a medication prescribed for heart conditions, including atrial fibrillation and heart failure. Apple cider vinegar can lower potassium levels, which may worsen the side effects of digoxin.
When potassium levels drop, the risk of digoxin toxicity increases, which can cause nausea, vomiting, vision changes, and even serious heart issues.
What to Do:
It’s best to avoid ACV if you are taking digoxin, as the combination could result in dangerously low potassium levels. Talk to your doctor about safe alternatives for incorporating vinegar into your diet.
4. Blood Pressure Medications
ACV is believed to help lower blood pressure, which can be beneficial for people with hypertension. However, if you are already taking blood pressure medications, adding apple cider vinegar could lower your blood pressure too much, causing dizziness, fainting, or even shock in extreme cases.
Medications That Could Interact:
- Amlodipine
- Losartan
- Lisinopril
- Metoprolol
- Valsartan
What to Do:
If you’re taking blood pressure medications, consult your healthcare provider before adding ACV to your diet to ensure it won’t lower your blood pressure too much.
5. Laxatives
Apple cider vinegar is known to have a mild laxative effect. When combined with over-the-counter or prescription laxatives, it can increase the risk of dehydration and electrolyte imbalances, as both ACV and laxatives work to cleanse the digestive system.
This can lead to severe dehydration and low potassium levels, which can be harmful.
What to Do:
If you’re using laxatives regularly, avoid using apple cider vinegar to prevent potential complications.
6. Antifungal Medications
Some people use apple cider vinegar to fight fungal infections due to its natural antifungal properties. However, using ACV internally when you’re already on prescribed antifungal medication can lead to interactions, reducing the effectiveness of the medication or causing digestive issues.
Medications That Could Interact:
- Fluconazole
- Ketoconazole
- Itraconazole
What to Do:
If you’re on antifungal medications, it’s best to avoid taking apple cider vinegar internally. Talk to your healthcare provider for guidance.
7. Blood Thinners (Anticoagulants)
Apple cider vinegar contains acetic acid, which may potentially interfere with blood clotting. If you’re taking blood thinners, using ACV may increase the risk of bleeding, especially in higher doses.
Medications That Could Interact:
- Warfarin (Coumadin)
- Heparin
- Clopidogrel (Plavix)
What to Do:
If you’re on any blood-thinning medication, consult your doctor before using apple cider vinegar. They may advise you to avoid it entirely to prevent an increased risk of bleeding.
8. Antacids
Apple cider vinegar is highly acidic and may seem counterintuitive for acid reflux, but many people use it as a natural remedy. However, when taken with antacids, ACV may interfere with the medication’s ability to neutralize stomach acid, which could worsen acid reflux symptoms.
Medications That Could Interact:
- Tums
- Ranitidine (Zantac)
- Famotidine (Pepcid)
- Omeprazole (Prilosec)
What to Do:
If you’re using antacids to treat acid reflux or heartburn, speak to your doctor before adding ACV to your diet.
The Bottom Line: Is Apple Cider Vinegar Safe for You?
Apple cider vinegar has many health benefits, but it’s essential to approach it with caution, especially if you’re on medication. The acidity of ACV and its potential effects on blood sugar, potassium levels, and digestion can create complications when combined with certain drugs.
Here are some tips for safely incorporating ACV into your lifestyle:
- Talk to Your Doctor: If you’re on medication, consult your healthcare provider before using ACV. They can help you determine whether it’s safe for you and may offer alternative solutions.
- Moderation is Key: If you’re cleared to use ACV, use it in small doses. Generally, 1-2 tablespoons diluted in water per day is sufficient. Avoid consuming large quantities, as this increases the risk of adverse interactions.
- Monitor Your Body’s Response: Keep an eye out for any unusual symptoms, such as dizziness, digestive discomfort, or unusual bleeding, and discontinue use if you experience side effects.
- Use ACV Safely: Always dilute ACV in water to prevent tooth enamel erosion and throat irritation. Drinking ACV straight can cause damage to the mouth, teeth, and digestive tract over time.
Apple cider vinegar can be a fantastic addition to your health regimen, but it’s important to recognize its potential interactions with medications.
Whether you’re using it to manage blood sugar, improve digestion, or promote weight loss, understanding the risks can help you make informed choices for your well-being.
Always prioritize safety and consult your healthcare provider to ensure ACV is the right choice for you.
