Can I be allergic to insulin?

After injecting insulin, some friends will experience allergic reactions in their bodies, such as fever, itching, swelling and other discomforts. Symptoms of insulin allergy can include local and systemic, so after injecting insulin, you also need to pay attention to whether your body has any discomfort symptoms. If so, you need to seek timely review and diagnosis.

Insulin allergic reactions generally manifest as fever, itching, edema, asthma and other reactions after insulin injection. There are many adverse reactions caused by insulin, such as hypoglycemia, hyperplasia or atrophy of subcutaneous tissue, edema, allergic reactions, etc. Among them, the allergic symptoms caused by allergic reactions have a great impact on human health, so everyone should pay more attention.

Symptoms of insulin allergy generally include local symptoms and systemic symptoms. Local allergic symptoms are burning sensation, redness, itching, swelling, blisters, nodules or rash at the insulin injection site, which usually occur within 2 weeks after treatment. Systemic allergies occur more frequently in patients who interrupt insulin treatment and then restart it, and are manifested by edema of the face and oral mucosa, systemic urticaria, wheals, vomiting, abdominal discomfort, and in severe cases, difficulty breathing, asthma, low blood pressure, and even shock and death. In this case, you must be sent to the hospital for emergency desensitization in time.

Most allergic symptoms usually manifest as local symptoms. Patients will first experience itching at the injection site; followed by a local urticaria-like rash; there will also often be gastrointestinal symptoms such as nausea, vomiting, and diarrhea, but don't worry, such symptoms will often disappear automatically after continuing to use the medication. Patients who are allergic to penicillin or have a history of allergies to other drugs, or have used insulin intermittently, are more likely to have an insulin allergic reaction, and patients should pay special attention to this. People who are allergic to fish should try not to use insulin containing protamine.

That’s all I have to say about the symptoms of insulin allergy. In fact, allergic reactions caused by insulin are rare. This reaction is largely related to individual differences and the strength of the immune function of the patients. So everyone must pay attention to consult the doctor and use the medicine according to their own physical condition to avoid the occurrence of some adverse reactions.
