What medications react with quinine?

Quinine can interact with several medications, including anticoagulants like warfarin, increasing the risk of bleeding. It may also interact with certain antiarrhythmic drugs, such as digoxin, potentially increasing their effects and side effects. Additionally, medications that affect the liver enzymes responsible for metabolizing quinine, such as some antifungals and antibiotics, can alter its levels in the body. Always consult a healthcare provider before combining medications with quinine.
