Urticaria can be treated with injections, commonly including antihistamines or corticosteroids, but these should be used only after a doctor's evaluation. It is recommended to first determine the cause and then choose an appropriate treatment plan under the guidance of a doctor.
1. **Indications for Injection**
If the rash is widespread, the itching is severe, or oral medication is ineffective, the doctor may recommend an injection. For example, in emergency situations such as acute attacks accompanied by difficulty breathing, injections can provide rapid relief of symptoms.
2. **Common Types of Injectable Drugs**
Antihistamine injections, such as diphenhydramine, can relieve itching and redness; short-term use of steroid injections, such as dexamethasone, is suitable for more severe symptoms. The dosage and frequency of these medications must be strictly controlled.
3. **Precautions**
Injections are not the first choice and are usually used for short-term control. Long-term, repeated injections of hormones may cause side effects, such as weakened immunity. You should inform your doctor about your health condition and allergy history before treatment.
It is recommended to first record the pattern of flare-ups and avoid scratching and contact with suspected allergens. If symptoms recur, consult a dermatologist promptly so that a comprehensive treatment plan including oral medications, topical medications, or injections can be developed. Do not self-medicate.
