Second Line

"Second line" typically refers to additional measures or treatments taken if the initial approach doesn’t fully resolve a problem, often in medical contexts. For example, after the first set of medications or therapies doesn’t work, healthcare providers may move to second-line options, which might be stronger or different. It can also apply in other fields like customer support or military strategy, where it indicates a subsequent level of action or response. Essentially, the second line acts as a backup or next step to better address an ongoing challenge after the first attempt has been made.
