Since there are times when we cannot avoid taking drugs to heal, is there anything we can do to help us consume medicines wisely and lower the risk of damaging our health? Medical doctors advocate for consulting a medical professional and strictly following their instructions for a medication’s use. Why is this so important? Before deciding how to administer a drug, a physician considers the drug’s characteristics, the dosage, the route of delivery, how the drug moves through the body, and the possible side effects. The route of delivery depends on three main factors: the part of the body being treated, the way the pharmaceutical works within the body, and the formula of the remedy.
