Do you know what happens to your skin when you get an allergic reaction? You’ve got a red bumpy rash with a few hives scattered around. You’re not sure what causes the rash and how long these bumps will last. Luckily for you, this article is about that. What are the hives that occur during an allergic reaction? How long do they last? What should you do after getting one? I reveal all in this post.


Allergic reactions are a common occurrence amongst people around the world. In most cases, a person’s immune system mistakes particular environmental factors for diseases or foreign bodies and initiates a defense mechanism against that particular substance. However, not all allergic reactions are harmful and do not necessarily deviate from the norm.

Some allergic reactions may be deemed more of a nuisance than anything else. An itchy hive is one such example wherein an individual may suffer from an allergic reaction to some sort of pollen or insect sting and develop what is commonly known as hives or urticaria. The period these temporary hives last after an allergic reaction will largely depend on the cause of the said attack.

How Long Do Hives Last After Allergic Reaction?

Hives, or urticaria, are a common allergic reaction that causes red welts on the skin. They can be caused by many things, including insect bites and medications.

The good news is that hives will go away on their own, but how long they last depend on what caused them. If you’re having an allergic reaction to something like pollen or food, your hives should fade within about 24 hours. However, if you have an allergic reaction to a medication such as penicillin, then it may take up to three days for your hives to completely disappear.

Other factors can affect how long your hives last after an allergic reaction:

  • If you’ve had hives before, they may come back quicker than usual because your body has already built up antibodies against the allergen it thinks is causing your symptoms (in this case, a certain type of pollen).
  • If you have a latex allergy, you could experience hives after wearing gloves or dental dams made from latex material these types of products often contain proteins called “rubbers” that cause an immune system response similar to those experienced when someone comes into contact with foods they’re allergic to (such as peanuts).
  • It depends on the cause of your hives. Hives can last anywhere from a few minutes to several days, but it’s important to note that hives are often associated with an allergic reaction.
  • If you’re experiencing hives for the first time and you’ve been diagnosed with an allergy, then you probably should see your doctor immediately. A doctor can help determine what caused your reaction and how severe it is. In some cases, they might prescribe medication to treat the symptoms or even give you shots to reduce swelling in your body.
  • If you’ve never experienced hives before and aren’t sure what’s causing them, then it’s best to call the doctor right away so that you can get medical attention as soon as possible. The doctors will be able to treat any underlying issues (such as an infection) while also calming down any swelling that may be affecting your body at this point.”
