What it means
A loading dose is a larger-than-usual initial dose given at the start of treatment to quickly bring a drug to a therapeutic level in your body. After the loading dose, smaller regular maintenance doses keep the drug at that effective concentration. Loading doses are used for medications that take a long time to accumulate in the body, such as certain heart rhythm drugs, blood thinners, and some antibiotics, when rapid treatment is necessary. Your provider will explain if a loading dose is part of your plan. Do not skip or modify a loading dose without guidance, as doing so can delay your treatment response.
How to say it
