1. Blood Thinners (such as Warfarin)
   Blueberries contain small amounts of vitamin K, which is important for blood clotting. If you're taking blood thinners like warfarin, be cautious. Excessive blueberry consumption may affect the medication’s effectiveness and increase the risk of bleeding.

2. Diabetes Medications
   Blueberries help lower blood sugar levels, which could interfere with diabetes medications such as insulin or oral medications. Eating large amounts might cause a sharp drop in blood sugar.

3. Blood Pressure Medications
   Blueberries act as antioxidants and may help lower blood pressure. If you’re taking blood pressure medications such as ACE inhibitors, it’s best to consume blueberries in moderation, as excessive intake could result in a further drop in blood pressure.

4. Anti-Inflammatory Drugs (NSAIDs)
   Blueberries can enhance the effect of anti-inflammatory drugs like ibuprofen or aspirin. This can increase their impact on the stomach, leading to inflammation or ulcers.

5. Chemotherapy Medications
   Due to their antioxidant content, blueberries may interfere with chemotherapy drugs, which could impact their effectiveness. Consult your doctor before consuming large amounts of blueberries while undergoing chemotherapy.

6. Antibiotics
   Blueberries may affect the absorption of medications such as tetracycline or doxycycline, reducing their effectiveness. Be mindful when consuming these medications along with blueberries.

7. Antifungal Medications
   Some medications like fluconazole may be affected by compounds in blueberries like anthocyanins and flavonoids, reducing their effectiveness in fighting fungi.

8. Cholesterol-Lowering Medications (Statins)
   Blueberries contain antioxidants that may enhance the effect of statins such as atorvastatin or simvastatin, which could lead to an excessive drop in cholesterol levels, potentially posing a risk to heart health.

9. Antidepressants (SSRIs)
   Some research suggests that blueberries may increase serotonin levels in the blood, potentially enhancing the effect of antidepressant medications like SSRIs. This could lead to fatigue, anxiety, and increased heart rate.

10. Thyroid Medications
    Blueberries may affect the absorption of thyroid medications like levothyroxine. Consuming large amounts could impair the medication’s ability to regulate thyroid hormones.

11. Antacids
    Blueberries can reduce the absorption of antacids like omeprazole, which could affect their ability to reduce stomach acidity.

12. Antiviral Medications (such as HIV or Hepatitis C)
    Blueberries may interfere with the effectiveness of antiviral medications, leading to reduced treatment efficacy or impacting viral levels in the blood.

13. Diuretics (Water Pills)
    Blueberries contain potassium, which may increase potassium levels in the blood when consumed with diuretics. Monitoring electrolyte levels in the body is important.
