Drowsiness after chemotherapy usually takes more than one week to subside, and the specific duration depends on the patient's physical condition. If the patient is in relatively good health after chemotherapy, drowsiness generally improves within a week. However, if the patient has a weak constitution or poor overall condition, it may take one to two weeks or even longer for symptoms to recover.
