What to do if you are allergic to medication

When an allergic reaction occurs after taking medication, patients should immediately take the following measures:

1. Discontinue the medication promptly: The priority is to stop taking the medication that may have triggered the allergic reaction, to prevent further exposure and worsening of symptoms.
2. Drink plenty of water: It is recommended to drink 200-500 mL of water in small amounts frequently, to promote metabolism and elimination of the drug from the body, aiding in faster resolution of allergic symptoms.
3. Skin care: If symptoms such as rash or itching appear on the skin, avoid frequent squeezing or scratching. The skin can be rinsed with running water to soothe and calm irritation.
4. Medication treatment: Assess the severity of the patient's condition. For mild allergic reactions such as rash or itching, symptoms can be relieved with oral antihistamine medications. For moderate to severe allergic reactions, such as difficulty breathing or a drop in blood pressure, immediate medical intervention is required, which may include administration of epinephrine, oxygen support, establishing intravenous access, and other emergency measures.

In subsequent treatment, alternative medications should be selected, and consideration should be given to performing drug allergy testing to ensure safe medication use. Throughout the process, effective communication with the patient and providing necessary psychological support are also very important.
