Itchy skin or pruritis can result from conditions like eczema or dermatitis. Less commonly, it can stem from more serious conditions, including kidney failure and liver disease.

Itchy skin is an irritating and uncontrollable sensation that makes you want to scratch to relieve the feeling. Possible causes for itchiness include internal illnesses and skin conditions.

Some causes of itching affect just one area, while others can make you feel like your whole body is itching. In some cases, itching may also be worse at night.

Many causes of itching are not a cause for concern, and they respond to over-the-counter treatments, moisturizers, or home remedies.

However, it’s best to contact a doctor if the cause isn’t obvious, if the itching is severe or persistent, or if you are concerned about it. They can treat any underlying conditions and provide medications to relieve discomfort.

Which home remedies and medical treatments can help manage itching?

Contact your doctor if:

  • You don’t know what’s causing your itching.
  • It’s severe.
  • You experience other symptoms along with the itching.

It’s important to contact your doctor for a diagnosis when the cause isn’t obvious, because some of the causes of itching are serious, yet treatable, conditions.

Your doctor will give you a physical examination and ask you several questions about your symptoms, such as:

  • How long have you had the irritation?
  • Where on the body is the itching occurring?
  • Does it come and go?
  • Have you been in contact with any irritating substances or new scented products?
  • Do you have allergies?
  • Where is the itching most severe?
  • What medications are you taking, or have recently taken?
  • Do you have any other symptoms such as fatigue, unusual sweating, chronic cough?
  • Have you traveled recently?

You may need more testing if your doctor can’t determine the cause of your itching from your answers and a physical exam.

Tests include:

  • Blood test. This may indicate an underlying condition.
  • Test of your thyroid function. Thyroid testing can rule out thyroid issues.
  • Skin test. This test can determine if you’re having an allergic reaction to something.
  • Scraping or biopsy of your skin. Your doctor may use these tests to determine if you have an infection.

When or if your doctor has pinpointed the cause of your itchiness, they can treat the cause of your itching. They may also recommend a topical medication to decrease your itching. If the cause is a disease or infection, your doctor will suggest the best course of treatment for the underlying problem.

When the cause is more superficial, you may receive a prescription for a cream that will help relieve the itching.

Treatment options for itchy skin can vary depending on the cause. Oral medications, topical medications, lifestyle changes, and other natural remedies may be beneficial.

Oral medication

Oral medications could provide relief from itchy skin caused by several conditions, including:

  • allergies
  • fungal infections
  • autoimmune disorders
  • cirrhosis
  • insect bites or stings
  • impetigo
  • eczema
  • dermatographia
  • hives and rashes

According to a 2016 review, medications that may be beneficial include:

  • Antihistamines. Oral antihistamines are used to treat allergic reactions and itchy skin or rashes caused by insect bites or stings, hives, eczema, dermatographia, and contact dermatitis.
  • Oral steroids. Also known as corticosteroids, these drugs help alleviate inflammation and may be used to treat conditions like systemic lupus erythematosus (SLE), chronic hives, eczema, psoriasis, and severe allergic reactions.
  • Immunosuppressants. This type of medication lowers immune activity. Immunosuppressant drugs may be useful to treat flare-ups caused by inflammatory conditions like SLE, chronic hives, and eczema.
  • Antifungal medications. These medications treat fungal infections and could reduce itching caused by athlete’s foot, jock itch, ringworm, or diaper rash. Some examples of antifungal medications include griseofulvin (Gris-PEG), fluconazole (Diflucan), and itraconazole (Sporanox).
  • Antibiotics. These drugs stop infections caused by bacteria. According to a 2019 study, some specific types of antibiotics, like rifampicin (Rifadin), are also used to control itching caused by liver disease. Oral antibiotics like amoxicillin/clavulanate (Augmentin) or clindamycin (Cleocin) can also treat severe cases of impetigo.
  • Beta-blockers. These medications are used to treat cirrhosis and portal hypertension, which is high blood pressure in the vein that carries blood to the liver.
  • Bile acid sequestrants. Medications like cholestyramine (Prevalite) help remove bile salts from the body, which can treat cirrhosis.
  • Antidepressants. Selective serotonin reuptake inhibitors (SSRIs) such as sertraline (Zoloft) and fluoxetine (Prozac) are often used to decrease itchy skin caused by liver disease.
  • Antiparasitic drugs. Medications like mebendazole (Vermox) and albendazole (Albenza) are sometimes prescribed for pinworm infection.
  • Diuretics. This type of drug can help lower fluid buildup to alleviate symptoms of cirrhosis.

Topical medication

Several types of topical creams can also help reduce itching caused by conditions such as:

  • allergies
  • fungal infections
  • hives and rashes
  • autoimmune disorders
  • eczema
  • lice infestation
  • insect bites or stings
  • scabies

Some of the most common topical medications that are used to treat itchy skin include:

  • Topical steroids. Steroid creams are applied to the skin to lower swelling and inflammation. They may be purchased over the counter or prescribed for conditions like eczema, scabies, psoriasis, neuropathic itching, SLE, contact dermatitis, insect bites, allergic reactions, and rashes.
  • Antifungal creams. These creams are often recommended to reduce itchy skin caused by fungal infections like ringworm, athlete’s foot, diaper rash, and jock itch.
  • Topical antidepressants. Doxepin (Zonalon) is a tricyclic antidepressant that is applied topically. According to a 2014 review, it is sometimes used to treat issues like eczema.
  • Topical anesthetics. These include pramoxine lotion, hydrocortisone-pramoxine cream, and other topical anesthetics. They’re used to provide temporary relief from pain and itching caused by conditions like scabies, insect bites or stings, hives, and rashes.
  • Scabicide. Permethrin cream is a type of topical scabicide prescribed for the treatment of scabies.
  • Zinc oxide. Available as either a cream or a paste, zinc oxide can decrease skin irritation caused by diaper rash or other types of rashes. It’s also found in products like calamine lotion.
  • Pediculicide. This type of topical medication is sometimes used to treat lice infestation.

Lifestyle changes

In addition to using oral or topical medications, some lifestyle changes may also help soothe itchy skin caused by:

  • allergies
  • dry skin
  • eczema
  • fungal infections
  • autoimmune disorders
  • cirrhosis
  • dermatographia
  • pinworm infection
  • lice infestation
  • impetigo

Here are a few lifestyle changes that could help prevent itchy skin:

  • Keep skin moisturized. Applying moisturizer daily, limiting your time in the bath or shower, staying hydrated, and using a humidifier can soothe itching caused by dry skin or eczema.
  • Wear comfortable, loose-fitting clothing. This can alleviate skin irritation and allow your skin to breathe, which may prevent fungal infections.
  • Eat a healthy, balanced diet. A 2020 review suggests that making changes to your diet could help control symptoms of psoriasis, lupus, cirrhosis, and eczema.
  • Reduce stress. According to a 2018 review, stress reduction techniques like yoga, meditation, and deep breathing exercises could prevent flare-ups of conditions like eczema, psoriasis, dermatographia, and SLE.
  • Avoid hot water. Hot water can irritate the skin and may worsen hives or dry skin.
  • Practice proper hygiene. Showering regularly, laundering clothes and bedding, and changing your clothing every day could protect against pinworm infection and lice infestation. It may also help stop the spread of other conditions, like impetigo and ringworm.
  • Use mild, hypoallergenic, and fragrance-free soaps and wipes. This can prevent irritation caused by dry skin, eczema, and diaper rash.
  • Avoid allergens. Identifying and avoiding foods, products, and environmental allergens that trigger symptoms for you can be beneficial.

Home care for itching

At home, you can do several things to help prevent and relieve itchy skin. Try:
