Mayo clinic 對盤尼西林服用時間的說法

"To help clear up your infection completely, keep taking this medicine for the full time of treatment, even if you begin to feel better after a few days. If you have a ”strep” infection, you should keep taking this medicine for at least 10 days. This is especially important in ”strep” infections. Serious heart problems could develop later if your infection is not cleared up completely. Also, if you stop taking this medicine too soon, your symptoms may return."
