Why won't my hives go away?
Q.I've gotten hives from time to time when I've been overly stressed. But now I have a case that won't quit after six weeks. What's going on?
A. No one welcomes these red, itchy welts that crop up on our skin. Many things can lead to a temporary case of hives, including allergic reactions to food, medications, bug bites, pollen, latex, or animal dander. Like you, some people also develop them when they're stressed, or in response to ultraviolet light or excess skin pressure. Hives are more common in women than men, especially from our 30s to 50s.
Most cases of hives go away within several days to a couple of weeks. If they last six weeks or longer, you may have autoimmune hives. This happens when your immune system mistakenly targets healthy tissue in this case, triggering a skin reaction. Autoimmune hives are more common in people with other autoimmune conditions, such as lupus, thyroid disease, rheumatoid arthritis, or celiac disease. Anyone whose hives last longer than a few weeks should see a doctor.

15 Ways to Get Rid of Hives
You may be able to relieve hives with home remedies, including aloe vera or an oatmeal bath, and over-the-counter products. But a doctor may need to treat severe or chronic hives.
Hives (urticaria) are a rash on your body. Identifying what triggered your hives is crucial to preventing them from happening again. If you can identify the trigger, you can avoid contact with it.
Although hives are often associated with allergic reactions, they can also occur due to:
Hives generally fade within 24 hours and dont require treatment.
However, you should seek immediate medical attention if you experience any of the following:
- dizziness
- swelling in your throat or face
- difficulty breathing
These may indicate a severe allergic reaction and require emergency care.
If your hives are milder, continue reading to learn how to ease any discomfort and speed up the healing process.
Some remedies and other products may cause a skin reaction. Its best to do a skin patch test before applying.
In most cases, home remedies can help you find relief. Here are a few ways to soothe itchy skin:
Use a cold compress
Applying something cool to your skin can help relieve irritation and swelling. To do this, grab a bag of frozen veggies or wrap a handful of ice in a towel and apply it to the affected area for up to 10 minutes. Repeat as needed throughout the day.
Take a bath with an anti-itch solution
There are several products you can add to a bath to relieve itching. These include colloidal oatmeal or one or two handfuls of baking soda.

Avoid products that may irritate the skin
Certain soaps may dry your skin and cause more itching when you have hives. Make sure to use a mild soap thats marketed for sensitive skin. These typically omit fragrance and irritating chemicals.
You should also avoid using irritating moisturizers or lotions. When in doubt, opt for a formula that targets sensitive skin, such as these options. Applying immediately after bathing may also help soothe the itch.
Keep things cool
Heat can make itchiness worse. Wear lightweight clothing and keep the temperature in your house cool and comfortable. Avoid sitting in direct sunlight.
If home remedies arent relieving your symptoms but you arent ready to head to the pharmacy you may want to give a few natural solutions a try.
Natural remedies arent regulated or approved by the Food and Drug Administration (FDA), so use them with caution.
Witch hazel
The natural tannins found in the herb witch hazel can help relieve irritation. Despite this, it
You can apply witch hazel to your skin like a mask a few times each day. Let it sit on the affected areas for about 20 minutes, and then rinse it off.
Aloe vera
Aloe vera is a natural anti-inflammatory. According to the
But, as with any new product, its important to do a skin patch test before application, especially if you have sensitive skin. Some aloe products may also have added fragrance or other chemicals, so be sure to read the label.
You can apply topical aloe vera to your hives as needed, likely a few times a day. Be sure to follow any instructions on the package.
If the above remedies arent enough to help your hives, over-the-counter (OTC) treatments may help relieve your symptoms. Not only can OTC options relieve itching and irritation, but they can also target your bodys histamine response, which is what causes hives.
Calamine lotion
Products containing calamine can help relieve itching by cooling your skin. You can apply calamine lotion directly to your skin:
- Make sure you mix the lotion before using it by shaking the container.
- Put some calamine lotion on a cotton pad or cloth.
- Apply the pad or cloth directly to the hives and let dry.
You can treat the hives with calamine lotion as necessary.
Diphenhydramine (Benadryl)
This oral antihistamine can reduce rash and other allergy symptoms like itching by working from the inside out.
Be sure to follow the dosage instructions on the package. Benadryl usually kicks in within an hour and should start to relieve your symptoms the same day.
Benadryl may cause drowsiness.
Fexofenadine (Allegra), loratadine (Claritin), and cetirizine (Zyrtec)
These antihistamines typically come in 12- or 24-hour formulas to provide extended relief. Theyre also less likely to cause drowsiness than diphenhydramine.
You may need to adjust the dosage to effectively treat hives, so talk with a doctor or pharmacist. They can advise you on how much to take and how often.
If youre experiencing severe or chronic hives, you may need prescription medication. Talk with a doctor about your symptoms and how you can best find relief.
Common prescription options include:
Prednisone (Deltasone)
This corticosteroid is taken orally. You should only use it for a short period of time as directed by a doctor. Corticosteroids can have side effects, especially if taken for extended periods of time. Side effects can include:
- elevated blood pressure
- elevated eye pressure (glaucoma)
- swelling
- weight gain
- immunosuppression, which means you may get infections more easily
To reduce side effects, take oral corticosteroids at a lower dose and transition to corticosteroid creams with your doctors supervision.
Omalizumab (Xolair)
This medication must be injected under the skin. This option is
- headache
- dizziness
- inner ear pain
- cold symptoms
Dapsone (Aczone)
This antibiotic is available topically and as an oral medication. This medication can treat inflammation due to hives or other skin conditions that are caused by bacterial infection. Its important to take all antibiotics as prescribed.
Antibiotics only help relieve symptoms caused by a bacterial infection.
Leukotriene-receptor antagonists
This nonsteroidal treatment option is taken orally. These drugs should be used only after steroid treatment and antihistamines have been unsuccessful. There is
- headache
- nausea
- cough
- low fever
If your symptoms worsen or last longer than a couple of days, you may want to talk with a doctor. They can identify the cause and provide medication to help relieve your symptoms. Understanding your triggers may help prevent future outbreaks.

When is a drug rash more than just a rash?
You were recently started on antibiotics for an infection and you are now doing well. But slowly your skin begins to itch, and the telltale signs of a rash are already popping up first on your torso, and now spreading to your arms and legs. What do you do? Should you worry? Should you see a medical professional?
Rashes are a common and pesky side effect of many medications. It can be so disheartening to be getting better from one ailment only to discover that you have another issue to address. While these itchy eruptions can be annoying, they usually run their course over a week or two and can be treated with topical medications.
But not all drug rashes are created equal and some can even be deadly. Luckily the scary ones are pretty rare, but it's still a good idea to know how to spot them. How can you tell the serious rashes from ones that are just a nuisance, but will get better with time and treatment?
Types of drug rashes
There are two main allergic rashes that may happen after taking a drug. The most immediate type of reaction happens within hours. Hives appear and move around the skin. Since this process is related to the release of histamine, antihistamines (available over the counter at a drugstore) are the typical treatment.
There is also a delayed type of drug rash that comes up four to 14 days after you start taking a medication. Pink and red bumps appear on your chest and back, and spread to the arms and legs over the course of days. Unlike hives, these bumps don't move around, and after a few days things may start to get better, but you may have peeling skin much like a healing sunburn.
This delayed type of rash doesn't respond as well to antihistamines, but an over-the-counter topical cortisone cream (or one of its stronger prescription-strength versions) can help speed the healing process along.
When is a drug rash cause for concern and a visit to the ER?
With hives, the main concern is that you're experiencing a whole-body reaction that goes beyond the skin, one that can make breathing difficult or dangerously drops your blood pressure. If you experience either of these symptoms, it's very important to get to the ED.
These immediate, life-threatening reactions can be treated with steroids, epinephrine, and higher-dose antihistamines than you can find at the drug store. While they are scary, these types of allergic reactions to a drug are not hard to identify, and many doctors are skilled at spotting dramatic changes in your breathing or blood pressure. It's important to tell the doctor you see what medications you have taken and how long ago you took them.
Know the signs of severe cutaneous adverse reactions (SCARs)
In the more delayed type of rash, symptoms can be more difficult to diagnose. The most common triggers for these types of rashes include antibiotics, antiseizure medications, antigout medications like allopurinol, and even over-the-counter medications like NSAIDs. (This isn't a complete list, and any new medication should be regarded with caution.)
As for the rash, when it's just itching things are usually fine, but still a nuisance. When the skin starts to hurt, or turns a deeper purple color, doctors worry about something more serious. If your skin starts to blister up or you see pustules, or if you notice sores in your mouth, eyes, or your genitalia, these are red flags and you should get to an urgent care clinic or the ER and ask for a dermatology consultation. Sores in the mouth can be so severe that drooling becomes a common symptom, because patients avoid swallowing due to the pain.
If you start to feel ill, like you have the flu, or if you're getting puffy from swelling, especially in the face, this could mean it's a severe drug hypersensitivity syndrome. Sometimes people develop a fever, a drop in their blood pressure, or their liver, kidneys, and heart can all be affected by drug hypersensitivity syndromes. These are so severe that most patients need to be admitted to the hospital, and sometimes even to the burn or intensive care unit.
While there are different names for different types of severe drug reactions, including Stevens-Johnson syndrome (SJS), drug rash with eosinophilia and systemic symptoms (DRESS), and acute generalized exanthematous pustulosis (AGEP), they are often grouped together as severe cutaneous adverse reactions (SCARs).
What happens if you develop a SCAR from a medication?
The first step is getting evaluated by a specialist, either in a dermatological clinic or the hospital. Finding someone who has expertise in managing these types of reactions is critical. A doctor (usually a dermatologist) may biopsy your skin, and they may have to start systemic medications that suppress your immune system. Sometimes, patients with SCARs also require a stay in a hospital.
The most important thing you can do is to keep an eye on your skin and its symptoms if you're taking a new medication, or even if you've increased the dose of an old medication. If you suspect that you may be dealing with one of these SCARs, be sure to seek help from an expert, like a board-certified dermatologist, so that you can rest assured that you're getting the care you need. Patients who are treated appropriately generally do well. Your doctors should also report these reactions to the FDA.
Once you're on the mend, things can start to get back to normal, but it's important to follow up with your doctors because there are some long-term issues that are important to pay attention to. Ultimately your doctors and healthcare team will advise you on what exactly is safe in the future. Remember that if you're worried about one of these reactions, it's important to stop the medication as soon as possible, but with the input of your doctors.
