Apigenin + Theophylline

MODERATE — Monitor Closely

Apigenin and Theophylline — Risk of Theophylline Toxicity

Evidence level: MODERATE

What this interaction means

Apigenin blocks the liver enzyme (CYP1A2) that breaks down Theophylline. This could cause Theophylline to build up in your body to dangerous levels, causing nausea, rapid heartbeat, or seizures.

How it works (mechanism)

Apigenin is a potent CYP1A2 inhibitor. Theophylline is primarily metabolized by CYP1A2. Inhibition may increase theophylline plasma levels, risking toxicity. Theophylline has a narrow therapeutic index.

Practical advice

IMPORTANT: If you take Theophylline for asthma or COPD, inform your pulmonologist before using Apigenin. Request theophylline level monitoring. Consider avoiding this combination or using very low Apigenin doses.

Timing

CYP1A2 inhibition is not eliminated by timing separation. If combining, maintain consistent Apigenin dosing and monitor theophylline levels.

Risk factors

Higher risk for: elderly, those with liver or kidney impairment, polypharmacy (5+ medications), recent medication changes, or those with multiple chronic conditions. Consult your pharmacist for specific risk factors.

Symptoms to watch for

Nausea, vomiting, rapid heartbeat, tremors, restlessness, headache, seizures (signs of theophylline toxicity).

What to tell your doctor

Apigenin inhibits CYP1A2, the primary enzyme for theophylline metabolism. Request drug level monitoring. Discuss alternative calming supplements that do not affect CYP1A2.

Safer alternatives

Discuss safer alternatives with your healthcare provider. They can recommend substitutions based on your specific health goals while minimizing interaction risks. Always bring a complete list of everything you take to your appointments.
