Insect Bites
Insect bites and hives cause itchy, raised, red skin reactions — whether from a mosquito, bee, or an allergic flare-up (urticaria). They’re extremely common and usually easy to manage, and can be assessed confidentially without an in-person exam in uncomplicated cases.
Could It Be an Insect Bite or Hives?
- One or more red, itchy bumps at the site of a known or suspected bite or sting
- Raised, red or skin-coloured welts (hives) that can appear suddenly and move around the body
- Intense itching, sometimes with mild swelling around the affected area
- Welts that blanch (turn white) when pressed and typically fade within hours to a day
- Symptoms triggered by a new food, medication, heat, stress, or an unknown cause
- No difficulty breathing, throat tightness, or swelling of the face, lips, or tongue
Treatment
- Oral antihistamines (cetirizine, loratadine, fexofenadine, desloratadine, bilastine, hydroxyzine, and others) to relieve itching and reduce hives
- Topical anti-itch and anti-inflammatory options (hydrocortisone, calamine, pramoxine, benzocaine, lidocaine, menthol, zinc oxide) for localized relief at the bite or welt
- Guidance on identifying and avoiding the trigger, where one can be identified
- Clear guidance on signs of a more serious allergic reaction that need immediate attention
- Ontario pharmacists can assess and prescribe directly for uncomplicated insect bites and hives

Frequently Asked Questions.
What causes hives?
Hives (urticaria) happen when the body releases histamine in response to a trigger — often an allergen (food, medication, insect sting), heat, stress, or sometimes no identifiable cause at all. Insect bites cause a similar, localized histamine reaction right at the bite site.
How are insect bites and hives treated?
An oral antihistamine to calm the underlying reaction, plus a topical option (like hydrocortisone or calamine) for localized itch relief. Ontario’s minor ailments program allows pharmacists to assess and prescribe directly for uncomplicated cases.
How long until symptoms improve?
Antihistamines typically start relieving itching within an hour. Individual insect bites usually settle within a few days, while hives can resolve within hours to a couple of days, though some cases take longer.
What’s the difference between hives and a bite reaction?
A bite reaction is usually a single, localized bump right where you were bitten or stung. Hives are raised welts that can appear anywhere on the body, often in clusters, and can move or change shape over hours — a pattern that helps your pharmacist tell the two apart during assessment.
Can hives become a serious allergic reaction?
In most cases hives are uncomfortable but not dangerous. However, hives combined with swelling of the face, lips, or tongue, difficulty breathing, or dizziness can signal a severe allergic reaction (anaphylaxis) and need emergency care right away.
When should I seek in-person care instead?
Seek emergency care for difficulty breathing or swallowing, swelling of the face, lips, tongue, or throat, dizziness or fainting, or a known history of severe allergic reactions to bites or stings. Seek in-person care for hives lasting more than a few days, widespread or worsening symptoms, signs of infection at a bite site (increasing redness, warmth, pus), or multiple stings at once.
