Skin rash
Hello Dr.
Zhang,
My daughter is currently one year and two months old.
Two weeks ago, she had a cold with symptoms of a runny nose and nasal congestion.
After taking Secorine syrup for two days, I noticed red rashes on her back while bathing (scattered across her entire back).
The next day (January 3), I took her to a pediatric clinic where she was diagnosed with urticaria and prescribed medication including Secorine syrup and Periactin 4 mg, as well as DL-Methyl E and Noscapine tablets.
She occasionally develops small, irregular red rashes on her face that disappear within minutes, and her hands and feet also show similar rashes.
I can't assess her limbs well due to clothing.
The heat from bathing seems to exacerbate the rashes on her back and chest.
She does not scratch the rashes.
During this time, her diet has been normal with no unusual foods, and there have been no significant changes in her environment.
However, the rashes have continued intermittently.
On January 5, I returned to the pediatric clinic (her cold was still not resolved), and this time she was prescribed Spiz syrup, Somin, Acetylcysteine granules, and Noscapine tablets.
Until yesterday, she had finished all the medications, and her cold symptoms have improved significantly, with only a little runny nose remaining.
The frequency and extent of the rashes have also decreased until yesterday (the rashes turn white when pressed).
I would like to ask: Is this urticaria? If so, is it an autoimmune allergic reaction, or could it be triggered by food or environmental factors, or possibly related to her cold? Does she need further medical attention or medication? What is the likelihood of recurrence in the future? Are there any methods to improve this condition? Thank you!

Hello: The cold medicine for your daughter does not contain ingredients that are likely to cause hives.
Viral infections can also lead to hives, which will typically resolve on their own within a month, so there is no need to worry.
However, do not stop the allergy medication too quickly!

More Info
Urticaria, commonly known as hives, is a skin condition characterized by raised, itchy welts that can appear anywhere on the body. In young children, it can be particularly concerning for parents, especially when it appears suddenly and without an obvious cause. Your daughter's case, where she developed hives following a mild cold, raises several important considerations regarding the nature of urticaria and its management.
Firstly, it is essential to understand that urticaria can be triggered by various factors, including infections, medications, food allergies, environmental allergens, and even stress. In your daughter's situation, the timing of the hives following her cold suggests that it could be a response to the viral infection itself, which is not uncommon. Viral infections can lead to immune responses that manifest as hives, even if there are no other allergy symptoms present.
The medications prescribed by your pediatrician, such as Secorine (an antihistamine) and Periactin (another antihistamine), are commonly used to alleviate the symptoms of urticaria. These medications work by blocking histamine, a substance in the body that causes allergic symptoms. It is good to hear that your daughter's symptoms have improved with the treatment, as this indicates that the hives may be responding to the antihistamines.
Regarding your questions about the nature of the hives, it is likely that they are indeed urticaria. The fact that the welts appear and disappear quickly, and that they blanch (turn white) when pressed, is characteristic of hives. As for whether they are due to an allergic reaction, it is possible that they could be related to the viral infection or even a mild reaction to something in her environment, but without a clear trigger, it can be challenging to pinpoint the exact cause.
In terms of recurrence, urticaria can be episodic, meaning that it may come and go. Some children may experience recurrent hives, while others may have a single episode. If your daughter continues to have episodes of hives, it would be prudent to keep a diary of her symptoms, noting any potential triggers such as foods, activities, or environmental changes. This information can be valuable for your healthcare provider in determining the cause and appropriate management.
To improve your daughter's condition and reduce the likelihood of future outbreaks, consider the following recommendations:
1. Avoid Known Triggers: If you suspect certain foods or environmental factors may be contributing to her hives, try to avoid them. Common allergens include nuts, dairy, eggs, and certain medications.
2. Maintain a Cool Environment: Heat can exacerbate hives, so keeping her cool, especially during baths, may help. Use lukewarm water instead of hot water, and avoid long baths.
3. Monitor for Other Symptoms: Keep an eye on her overall health. If she develops additional symptoms, such as difficulty breathing, swelling of the face or throat, or persistent hives, seek medical attention immediately.
4. Consult an Allergist: If the hives persist or recur frequently, consider consulting a pediatric allergist. They can perform tests to identify specific allergens and provide tailored management strategies.
5. Follow-Up with Your Pediatrician: Regular follow-ups with your pediatrician are essential to monitor her condition and adjust treatment as necessary.
In conclusion, while urticaria can be distressing for both the child and the parents, it is often manageable with appropriate treatment and lifestyle adjustments. Keep communication open with your healthcare provider, and don't hesitate to seek further evaluation if her symptoms continue or worsen. Your proactive approach in seeking information and care for your daughter is commendable and will help ensure her well-being.
