(单词翻译:双击或拖选)

Spring is in the air. And so are those dang insects, hungry for a blood meal. The victim can wind up with a bunch of bites, red and itchy. So what drugs can quench² that itch¹? Maybe none, according to a study in the Drug and Therapeutics Bulletin.

Researchers reviewed the literature on a variety of treatments. Topical antihistamines³? Generally not recommended. They’re only marginally effective and shouldn't be used for longer than three days.

Oral analgesics⁴ like ibuprofen are sometimes recommended, but the scientists say there’s no evidence supporting that. Topical anesthetics such as lidocaine are only marginally effective and can sensitize the skin—meaning the itching⁵ could ultimately get worse.

And common topical steroids like hydrocortisone? The problem here is that they’re not supposed to be used on broken skin. And if you’ve been scratching, that skin may already be broken.

The authors recommend a simple approach: clean the area, and use a cold pack to tamp⁶ down inflammation and numb⁷ the nerves. If you haven’t broken the skin, try the steroid cream. But your best approach may be ice. The cold hard fact is that this cold hard treatment works.
