Allergy is an excessive immune response of the body to certain substances, which are medically known as allergens. Common allergic symptoms include skin itching and swelling, rashes and hives, sneezing and runny nose, coughing and wheezing, and eye-related symptoms. Patients can take antiallergic medications such as loratadine tablets, ebastine tablets, and montelukast sodium tablets under the guidance of a physician for treatment.

Allergy is an excessive immune response of the body to certain substances, which are medically known as allergens. Common allergic symptoms include skin itching and swelling, rashes and hives, sneezing and runny nose, coughing and wheezing, and eye-related symptoms. If any abnormal symptoms occur, prompt medical attention is recommended. Specific analyses are as follows:

1. Skin Itching and Swelling: One of the most common allergy symptoms is skin itching, which may be accompanied by localized or generalized discomfort. Additionally, under stimulation by allergens, the skin may develop localized or widespread redness and swelling, leading to erythema, papules, or wheals.

2. Rashes and Hives: Skin rashes are typical manifestations of allergic reactions, including erythema, papules, and vesicles. Hives represent a specific type of rash characterized by red, raised welts appearing across the body. These welts may fade quickly but can recur within 24 hours.

3. Sneezing and Runny Nose: Common symptoms of allergic rhinitis include sneezing and nasal discharge, often triggered by allergens entering the nasal cavity, causing nasal mucosal edema and increased secretions.

4. Coughing and Wheezing: Allergies may lead to airway inflammation, resulting in coughing and wheezing. Severe allergic reactions can cause bronchospasm, leading to difficulty breathing and pronounced wheezing.

5. Eye Symptoms: The eyes are also commonly affected by allergies, with symptoms such as redness, swelling, tearing, and itching. Allergic reactions in ocular tissues typically manifest as itchy and swollen eyes.

Patients may take antiallergic medications such as loratadine tablets, ebastine tablets, or montelukast sodium tablets under the guidance of a physician for treatment.

Can someone with an egg allergy receive the MMR (measles, mumps, and rubella) vaccine?

Whether individuals with egg allergy can receive the measles, mumps, and rubella (MMR) vaccine depends on the severity of the allergy. Those with mild allergies may be vaccinated after proper evaluation. However, vaccination should be avoided in cases of severe allergy or during an active allergic reaction. Before vaccination, it is essential to inform the healthcare provider about specific symptoms related to the egg allergy and cooperate with the medical assessment. After vaccination, keep the injection site clean and dry, and avoid scratching.

What are the symptoms of drug-induced liver injury?

Typical symptoms of drug-induced liver injury include general fatigue, gastrointestinal discomfort, abnormalities of the skin and mucous membranes, pain in the liver area, and fever. Once the above symptoms appear—especially in individuals with a recent history of medication use—it is important to seek timely medical evaluation and liver function testing at a hospital. When liver metabolic function is impaired, insufficient energy production leads to persistent fatigue that worsens after physical activity and is difficult to relieve even with rest.
