Risk factors

Higher risk for: those with liver impairment (azole antifungals are hepatotoxic), concurrent CYP3A4 substrate use, elderly, renal impairment, or those on multiple QT-prolonging medications.

Antifungal medications are potent enzyme inhibitors — monitor carefully when combining Fluconazole with Astragalus. Watch for: unusual nausea, vomiting, abdominal pain, yellowing of skin or eyes (liver stress), headache, dizziness, skin rash, or signs the other medication is stronger or weaker than expected. When to seek emergency help: Severe abdominal pain, dark urine with yellow skin/eyes, irregular heartbeat, fainting, severe rash with blistering, difficulty breathing, or swelling of face/tongue. Report all medications to your prescriber — dose adjustments may be needed.

What to tell your doctor

No urgent need to discuss, but always keep your doctor informed of your full supplement and medication list. An up-to-date list helps them make the best treatment decisions.
