What should I do if my lower eyelid is swollen from a mosquito bite?

The lower eyelid swelling caused by a mosquito bite can be treated with methods such as cold compresses, topical application of aloe vera gel or medications, and oral medications.

1. Cold Compress

A cold compress helps constrict blood vessels, thereby reducing eyelid swelling and alleviating symptoms including ocular pruritus, pain, and redness.

2. Topical Application of Aloe Vera Gel or Medications

For mild eyelid swelling, topical application of aloe vera gel may be used; it possesses anti-inflammatory, antimicrobial, and mild anti-edematous properties. However, if the swelling is severe and accompanied by symptoms such as eyelid pain or pruritus, prompt medical consultation is recommended. Under physician guidance, topical anti-allergic ointments—such as tacrolimus ointment or butenafine hydrochloride cream—may be prescribed to relieve itching, reduce inflammation, and alleviate swelling.

3. Oral Medications

In cases of pronounced swelling or a robust allergic reaction following a mosquito bite, oral antihistamines may be prescribed under medical supervision. Commonly used agents include cetirizine hydrochloride tablets and loratadine tablets, which help alleviate associated symptoms.
