Are there any interactions with medications?



Medications taken by mouth (Oral drugs)
Interaction Rating: Moderate Be cautious with this combination.
Talk with your health provider.

Quince contains a type of soft fiber called mucilage. Mucilage can decrease how much medicine the body absorbs. Taking quince at the same time you take medications by mouth can decrease the effectiveness of your medication. To prevent this interaction take quince at least one hour after medications you take by mouth.
