Interaction Details
Doxycycline monohydrate is classified as belonging to the following category: P-Glycoprotein Substrates
Schisandra might increase the levels and clinical effects of P-glycoprotein substrates.
In vitro research shows that schisandra extracts and constituents such as schisandrin B inhibit P-glycoprotein mediated efflux in intestinal cells and in P-glycoprotein over-expressing cell lines. Additionally, a small clinical study shows that schisandra increases the peak concentration and overall exposure to talinolol, a P-glycoprotein probe substrate. Theoretically, schisandra might inhibit the efflux of other P-glycoprotein substrates.

Schisandra Overview
Schisandra is a plant that is native to parts of Asia, and is known for its small, red berries. These berries are often dried and sold as a dietary supplement to be used as a natural remedy for a wide range of health conditions, including fatigue, anxiety, and respiratory problems. Some people also use schisandra to improve sleep quality and reduce the symptoms of menopause. It is considered an 'adaptogen', which is believed to help the body adapt to stress.
