Key takeaways:
Antihistamines are usually the best medication for hives. Newer antihistamines — like cetirizine, loratadine, and fexofenadine — are safer than diphenhydramine (Benadryl). And they’re equally effective at reducing itching and redness.
Cool compresses, calamine lotion, and oatmeal baths are at-home remedies that can help treat hives quickly.
Hives usually go away on their own. But get medical care if you have signs of a severe allergic reaction, or over-the-counter medications aren’t helping.
Hives, also called urticaria, show up as itchy, red bumps on the skin. Hives can be caused by many different things, including:
Certain medications
Pollen
Pet dander
Infections
Extreme heat or cold
Most of the time hives will go away on their own. But while you have them, hives can be very uncomfortable and itchy. Fortunately, there are things you can do at home to treat hives. Let’s review different ways to get rid of hives quickly.
Search and compare options
1. Cool compress or cold shower
A cool compress is a quick way to relieve itching from hives. Lowering the temperature of the skin can help bring down swelling and reduce the itching sensation, at least temporarily.
To make a cool compress, run a washcloth under cold water or wrap an ice pack in a towel. Apply the compress for 10 to 15 minutes at a time. But, if you think your hives are triggered by the cold, skip the cool compress, since this could aggravate your symptoms. If hives cover a large area of your body, try taking a cool shower instead.
2. Aloe vera
Many people use aloe vera gel to help soothe sunburned skin. In addition to relieving itching from minor burns, there’s some evidence that aloe vera may help people with other skin conditions. That’s because aloe vera has anti-inflammatory properties and helps hydrate the skin.
To reduce itching from hives, try applying a thin layer of aloe vera gel. Be sure to test it out on a small area of skin first. Though it’s rare, people can have an allergic reaction to aloe vera.
3. Diphenhydramine (Benadryl)
Histamines are chemicals that make your skin become red and itchy when you have hives. Diphenhydramine (Benadryl) is an antihistamine. It works by blocking histamines. Benadryl usually comes as a pill or liquid taken by mouth.
This medication can cause side effects, like:
Drowsiness
Dizziness
Blurred vision
Increased risk of falls in older adults

That’s why it’s important to take the correct dose of Benadryl, and only use it when you have time to stay home and rest.
4. Other OTC antihistamines
If you’re looking for an antihistamine for hives that won’t make you drowsy, you can try one of the newer over-the-counter (OTC) medications, called second-generation antihistamines. They’re available as capsules and tablets, disintegrating tablets, and liquids. Examples include:
Cetirizine (Zyrtec)
Loratadine (Claritin)
Fexofenadine (Allegra)

Unlike Benadryl, second-generation antihistamines don’t cross from the bloodstream into the brain, so they’re less likely to cause side effects, like sleepiness and fatigue. And studies have shown they work as well as Benadryl for treating hives. That’s why experts often recommend them for treating hives.
5. Creams for hives (hydrocortisone and Benadryl cream)
Hydrocortisone is an OTC steroid cream that can be used on itchy skin. It lowers inflammation and has been shown to reduce itching for people with eczema and psoriasis. It’s not clear how effective it is at treating itching caused by other skin conditions, like hives.
Hydrocortisone cream can be applied 1 to 4 times per day for up to 2 weeks. Long-term use of steroid creams can lead to side effects, like redness or skin thinning. So, talk with your primary care provider if your hives aren’t improving with hydrocortisone cream.
Benadryl cream is another option that can be applied directly to the skin. However, there isn’t much evidence that Benadryl cream helps reduce itching very much. Benadryl cream can usually be applied 3 to 4 times a day, but you should always follow the directions of the product you’re using.
6. Calamine lotion
Made of zinc oxide and iron oxide, this distinctive pink liquid soothes and protects skin. There’s not much research on using calamine lotion to treat hives, but it has been shown to reduce itching from insect bites and poison ivy. So, it’s a safe OTC anti-itch treatment to try at home. Calamine lotion can dry out the skin, but otherwise most people don’t have any side effects.
7. Oatmeal baths
Oatmeal baths have been used to treat skin conditions for centuries — and there’s scientific evidence that it works. Colloidal oatmeal has antioxidant and anti-inflammatory properties.
To make your own oatmeal bath at home, follow these steps:
Grind 1 cup of oats in a blender or food processor.
Place the ground oats in a bathtub filled with lukewarm water.
Soak in it for at least 10 to 15 minutes.
8. Prednisone
Prednisone is a type of steroid pill that requires a prescription. It helps lower inflammation and can improve hives quickly. However, some studies show that it may not be any more effective than using antihistamines.
Prednisone is usually given as a short course, like for 5 to 7 days. Taking it for too long can increase some of its side effects, like osteoporosis and high blood pressure.
9. Self-care tips
Here are some other tips you can do at home to help minimize symptoms from hives:
Avoid scratching.
Choose loose-fitting clothes made of cotton.
Take warm (not hot) baths and showers.
Use gentle, fragrance-free soap and other skin care products.
When should you get medical care for hives?
Severe allergic reaction (anaphylaxis) is a life-threatening condition that needs emergency treatment. Get immediate medical care for hives if you have signs of anaphylaxis, including:
Swollen lips
Swollen tongue
Throat tightness
Difficulty breathing
Vomiting
Diarrhea
Feeling faint
If your hives aren’t getting better with home treatments — or if you’re unsure what’s causing your rash — talk with a healthcare professional. They may recommend a prescription medication or additional testing if the diagnosis is unclear.
Frequently asked questions
For most people, hives usually last anywhere from a few days to a few weeks. But sometimes they can last longer than that. Hives that last longer than 6 weeks are called chronic hives. Your dermatologist can help you figure out what’s causing them and find the best treatment.
Hives look like smooth, swollen patches of skin. They can look pink or red in fair skin and skin-colored or brownish in darker skin. They can range in size from small (like the size of a pencil eraser) to large (like the size of your palm or larger).
In general, most hives don’t spread by scratching. However, some hives are triggered when there’s pressure on the skin (an example is dermatographia). For people with this type of hives, scratching the skin can cause hives to form. No matter what’s causing your hives, it’s never a good idea to scratch them too much. This can lead to breaks in the skin and a skin infection.
Many different things can worsen, or trigger, hives. Some common examples include:
Stress or anxiety
Extreme heat or cold
Exercise
Hives may get worse at night because this is when the body’s anti-itch chemicals are at their lowest. Your skin temperature may also be higher at night, which can be a trigger for hives.
Many different illnesses can trigger hives. Some examples include:
Urinary tract infection (UTI)
Autoimmune thyroid disease
If you have hives and aren’t sure what’s causing them, a healthcare professional can help you figure it out.

The bottom line
Hives will usually go away on their own. You can help get rid of hives quickly with a combination of OTC medications and home remedies. Medications like cetirizine, loratadine, and fexofenadine are the best antihistamines for hives. They work as well as diphenhydramine (Benadryl) to relieve itching, without causing drowsiness. They can be used in combination with topical treatments, like oatmeal baths, aloe vera, and cool compresses.
