Interaction Details

There is often a lack of studies and data surrounding traditional medicine, especially concerning drug interactions, so it is important to always consult your provider before making any changes to your medication regimen.
Fever Bark Overview
Fever bark is the bark of the evergreen tree Alstonia constricta. The tree is native to tropical regions of Asia and is known for its tall, straight trunk and glossy, dark green leaves.
Alstonia constricta is used in traditional medicine to treat a variety of ailments, including fever, diarrhea, and infections. The bark of the tree contains several different alkaloids, including reserpine and yohimbine, which could cause serious side effects if misused. Unless you are under the direct supervision of a medical professional, the use of fever bark is not recommended.
Fever bark is sometimes referred to as Australian quinine, but it is not known to contain quinine.
Lansoprazole Overview
-
Prescription lansoprazole is used to treat the symptoms of gastroesophageal reflux disease (GERD), a condition in which backward flow of acid from the stomach causes heartburn and possible injury of the esophagus (the tube between the throat and stomach) in adults and children 1 year of age and older. Prescription lansoprazole is used to treat the damage from GERD in adults and children 1 year of age and older. Prescription lansoprazole is used to allow the esophagus to heal and prevent further damage to the esophagus in adults with GERD. Prescription lansoprazole is also used to treat ulcers (sores in the lining of the stomach or intestine), to prevent more ulcers from developing in adults whose ulcers have already healed, and to decrease the risk that adults who are taking nonsteroidal anti-inflammatory drugs (NSAIDs) will develop ulcers. Prescription lansoprazole is also used to treat conditions where the stomach produces too much acid, such as Zollinger-Ellison syndrome in adults. Prescription lansoprazole is also used in combination with other medications to treat and prevent stomach ulcers caused by a certain type of bacteria (H. pylori) in adults. Nonprescription (over-the-counter) lansoprazole is used to treat frequent heartburn (heartburn that occurs two or more days per week) in adults. Lansoprazole is in a class of medications called proton pump inhibitors. It works by decreasing the amount of acid made in the stomach.
