Can I drink orange juice with my antibiotics? Do these two medications interact? Drug interactions can result in increased or decreased effects of one or more drugs—bad news for those taking more than one medication. But there's no need to worry! Reddendale Pharmacy has all the answers you need with our drug interaction checker. We will check all your prescriptions for interactions with each other before dispensing any medication, because we care about your health, safety, and well-being. We are also available for consultation about foods (such as grapefruit or herbal supplements like St. John’s Wort) that are known to interact with certain drugs.
