Have you ever wondered why people respond differently to the exact same medication? Some may have no reaction to a medication, while others may experience bad side effects or even life-threatening toxicities. We at Josefs Pharmacy can help using precision medicine technologies such as DNA medication sensitivity testing to help patients avoid drugs they cannot process or metabolize well. Our simple cheek swab test is the most comprehensive test available and examines 18 genes associated with how over 200 medications react with your body. This helps your physician prescribe the right medication from the beginning to enhance therapeutic benefits, prevent unwanted side effects, decrease wasted time and money from taking ineffective medications, and possibly save lives. This is not a test for genetic susceptibility of inherited diseases. Your results are only related to how your body reacts with medications, not if you will develop certain diseases, such as cancer.
