There are many medications to choose from for redness caused by bug bites, but the general choice is topical medication. If the itch is very pronounced or the redness is relatively large, you can also take oral anti-allergy medications, such as cetirizine and loratadine. There are also more topical medications to choose from. The first choice is Furfurylate lotion, a salve that can be shaken well before each use and applied several times a day, which can be bought in general pharmacies and is very cheap. You can also choose creams, such as Dermaphor cream or Denide cream. Dermatologic cream is a proprietary Chinese medicine with antiseptic and antipruritic effects, and Denide cream is a weak hormonal drug that does not cause problems with short-term use.
