  1. Gastrointestinal issues: Berberine may cause diarrhea, constipation, abdominal discomfort, or bloating in some individuals.
  2. Low blood pressure: Berberine can lower blood pressure, so individuals with already low blood pressure should use caution.
  3. Allergic reactions: In rare cases, berberine can cause allergic reactions, such as rash, itching, or swelling.

Berberine can also interact with certain medications, including:

  1. Blood sugar-lowering medications: Berberine may enhance the effects of these medications, leading to excessively low blood sugar levels (hypoglycemia).
  2. Blood pressure-lowering medications: Combining berberine with these medications may cause blood pressure to drop too low.
  3. Immunosuppressant drugs: Berberine may interfere with the effectiveness of these medications.
  4. Cytochrome P450 substrates: Berberine can affect the metabolism of drugs that are metabolized by this enzyme system, potentially altering their effectiveness or toxicity.

It is crucial to inform your healthcare provider about all medications, supplements, and medical conditions you have before starting berberine supplementation. They can assess potential interactions and advise you on the appropriate use of berberine for your specific situation.
