Introduction
It is possible to experience全身 itching after a contrast-enhanced CT scan, which may be a normal phenomenon or an allergic reaction. Treatment should be targeted according to the specific cause. Patients are advised to get adequate rest and avoid excessive fatigue in daily life. If any discomfort occurs, they should seek medical attention promptly for evaluation and timely treatment to prevent delay in managing the condition.
Itching all over the body after a contrast-enhanced CT scan may be a normal phenomenon or could indicate an allergic reaction, and treatment should be tailored according to the specific cause. The details are as follows:
1. Normal phenomenon
Contrast-enhanced CT is an imaging examination method based on non-contrast CT, in which suspicious areas are specifically scanned after intravenous injection of contrast agent. This technique helps more clearly define the extent and nature of lesions. If a patient is intolerant to the contrast agent, an allergic reaction may occur, which is considered a normal response. Usually, no special treatment is required. The itching is typically mild and gradually resolves as the body metabolizes the agent.
2. Allergic reaction
If a patient has an allergy-prone constitution and is sensitive to components in the contrast agent, an allergic reaction may occur, manifesting as itching, rashes, and other discomforts. Symptoms can be relieved under a doctor's guidance with antihistamines such as loratadine tablets or cetirizine hydrochloride tablets.
Patients are advised to get adequate rest in daily life and avoid excessive fatigue. If any discomfort occurs, they should seek medical attention promptly for evaluation and timely treatment to prevent delays in care.
