Potential Drug Interactions
Damp Heat Derma Relief contains several potent Chinese herbs, including strongly Heat-clearing, Damp-drying, and Blood-cooling herbs (notably Long Dan Cao, Huang Qin, Huang Bai, and Zhi Zi) with known hepatic, gastrointestinal, and immune-modulating activity. Because herb-drug interaction research in dogs and cats is limited, pets taking prescription medications should use this formula under veterinary supervision. Avoid use during pregnancy or with Qi deficiency.
Extra caution may be appropriate for pets receiving hepatic medications, gastrointestinal medications, immunosuppressive drugs, corticosteroids, or multiple prescription medications.
