When treating urticaria, doctors may choose to inject medications depending on the condition. Common medications include antihistamine injections and corticosteroid injections, but the specific medication must be determined by the doctor after evaluation.

1. Antihistamine injections: These medications can quickly relieve itching and wheals, and are suitable for acute flare-ups of symptoms when oral medications are not effective, helping to control allergic reactions.

2. Glucocorticoid injections: Doctors may use them for a short period of time to reduce inflammation and swelling when symptoms are severe or recurrent, but they are not usually used for a long period of time.
3. Other treatment options: For chronic or special types of urticaria, doctors may also consider injection therapy such as immunomodulation, which requires a customized treatment plan based on individual circumstances.
Please note that injection therapy is not the first choice; oral medications are generally tried first. If urticaria flare-ups are frequent or affect your daily life, it is recommended to seek medical attention promptly so that a doctor can examine you and choose an appropriate treatment plan. Avoid self-medication and keep a record of triggers such as food and environment, which will help with daily management.
