Antifungal medications are potent enzyme inhibitors — monitor carefully when combining Fluconazole with Vitamin B2. 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.
No urgent discussion needed, but keep your provider informed. Say: "I take Fluconazole alongside Vitamin B2 — anything I should know?"
