Do not combine without physician supervision. If you are already taking both Ginseng and Theophylline, contact your healthcare provider today. Do not stop any medication without professional guidance.
Mechanism
Ginseng is a weak inhibitor of CYP3A4, which decreases metabolism of CYP3A4 substrates, potentially increasing their plasma concentrations and risk of adverse effects.
Effect
Increased plasma levels of theophylline (theophylline), potentially leading to toxicity or enhanced adverse effects.
Management
Monitor for increased adverse effects of theophylline. Dose reduction may be necessary. Consider alternative supplement or consult healthcare provider.

This combination is dangerous. Ginseng can slow down how your body breaks down theophylline, which may cause the medication to build up to unsafe levels. This increase can lead to a higher risk of serious side effects.
