Charak Samhita
निर्वृत्तेऽपि ज्वरे तस्माद्यथावस्थं यथाबलम्। यथाप्राणं हरेद्दोषं प्रयोगैर्वा शमं नयेत् ॥३३९॥
Therefore, the doshas should be eliminated from the body either by elimination or alleviation therapies depending upon the stage and strength of the doshas, even after the fever subsides in a patient of jwara.
