Hydrocortisone is a potent topical medication belonging to the corticosteroid class, designed to alleviate inflammation, swelling, and itching associated with various skin conditions. It's crucial to understand its applications, potential side effects, and proper usage to ensure safety and efficacy.
What is Hydrocortisone Cream?
Hydrocortisone is a type of medicine known as a steroid or corticosteroid. These medications work by reducing inflammation and swelling in the body. It is important to distinguish them from anabolic steroids, which are sometimes misused for muscle enhancement.
Most hydrocortisone creams and ointments are classified as "mild" steroids. This classification suggests they are generally associated with fewer side effects compared to stronger steroid medications. They are effective in treating a range of dermatological issues.
Uses of Hydrocortisone Cream
Hydrocortisone cream is commonly prescribed or recommended for the temporary relief of itching, redness, swelling, and discomfort caused by minor skin irritations and rashes. It is particularly useful for conditions such as:
- Eczema (Atopic Dermatitis): Characterized by inflamed, itchy, and dry patches of skin.
- Psoriasis: A chronic condition causing raised, red, scaly patches.
- Contact Dermatitis: Skin inflammation resulting from contact with an allergen or irritant.
- Seborrheic Dermatitis: Affecting areas rich in oil glands, leading to flaky, itchy skin.
- Reactions to Insect Bites and Stings: To reduce localized inflammation and itching.
- Minor Skin Irritations: Such as those from certain fabrics or chemicals.
- Feminine Itching: For temporary relief of external itching.
- Anal Itching: To alleviate discomfort.
In some cases, hydrocortisone may be combined with other active ingredients, such as anti-fungal medications, to address more complex skin issues.
How Hydrocortisone Works
Topical hydrocortisone functions by calming the body's immune response in the skin. It helps to reduce inflammation and swelling by inhibiting the release of substances that cause these reactions. Additionally, corticosteroids can narrow blood vessels at the application site, which can further contribute to reducing swelling.
Dosage Forms and Strengths
Hydrocortisone is available in various forms and strengths to suit different needs and body areas. Common dosage forms include:
- Cream: Typically easier to apply, absorbed quickly, and helps moisturize the skin.
- Ointment: Best for very dry skin as it creates a moisture-locking barrier and allows for deeper penetration of the active ingredient, making it more potent than creams.
- Lotion: Lighter in consistency, making it suitable for large areas of the body, hairy regions, or weeping skin.
- Solution/Liquid: Often used for scalp conditions.
- Gel or Jelly: May offer a cooling sensation.
Strengths commonly range from 0.1% to 2.5%, with higher concentrations usually requiring a prescription. It is essential to use the strength recommended by a healthcare professional or as indicated on the product packaging.

How to Use Hydrocortisone Cream
The method of application depends on the specific product (cream, ointment, lotion) and the condition being treated. Always follow the advice of your doctor or pharmacist, or refer to the instructions on the product label or patient leaflet.
General Application Guidelines:
- Wash your hands thoroughly before and after application.
- Clean and dry the affected area of the skin.
- Apply a thin layer of the cream, ointment, or lotion to cover the affected area.
- Gently rub the medication into the skin.
- Use the smallest amount needed to cover the affected area.
- Do not bandage, cover, or wrap the treated area unless specifically instructed by a healthcare provider.
- Avoid contact with eyes, mouth, and inside the nose. If contact occurs, rinse thoroughly with water.
- Do not use on the face, underarms, or groin area unless directed by a doctor.
- For scalp conditions, part the hair and apply the lotion or solution directly to the affected area, rubbing it gently into the scalp.
The frequency of application is typically once or twice a day, but can be up to four times a day, depending on the product and condition. Treatment duration should not exceed 7 days without medical consultation.
Measuring Dosage:
Dosage may sometimes be measured in fingertip units (FTU). One FTU is the amount of ointment or cream that fits onto the end of an adult's index finger from the tip to the first crease.
Storage
Topical hydrocortisone should be stored at room temperature, typically between 68°F to 77°F (20°C to 25°C). Store in a cool, dry place, away from direct sunlight, heat, and moisture. Avoid freezing. Always check the specific product label for detailed storage instructions.
Side Effects of Hydrocortisone Cream
While generally safe when used as directed, hydrocortisone cream can cause side effects, ranging from mild to rare but serious reactions.
Common Side Effects:
These are usually mild and may resolve as your body adjusts to the medication:
- Burning or stinging sensation at the application site
- Itching
- Irritation
- Dryness or flaking of the skin
- Redness
- Inflamed hair follicles (folliculitis)
Serious Side Effects:
These are less common and are more likely with prolonged use, application to large areas, or use of stronger, prescription-strength formulations.
- Allergic Reaction (Anaphylaxis): Symptoms may include swelling of the throat or tongue, a raised itchy rash (hives), and difficulty breathing. Seek immediate medical attention if these occur.
- Vision Problems: Such as blurred vision, cataracts, or glaucoma, especially with prolonged use near the eyes.
- Skin Changes: Thinning of the skin, easy bruising, stretch marks (striae), lightening of skin color (hypopigmentation), or changes in hair growth (unusual hair growth or hair loss).
- Skin Infections: Hydrocortisone can mask or worsen existing skin infections (bacterial, fungal, viral).
- Reduced Adrenal Function (Adrenal Insufficiency): Long-term use, especially over large areas or under occlusion, can suppress the body's natural production of cortisol. Symptoms include nausea, vomiting, weakness, fatigue, dizziness, low blood pressure, and increased thirst or urination.
- Cushing's Syndrome: Rare, but can occur with prolonged or extensive use, leading to symptoms like a rounded face, weight gain (especially in the upper body), fat buildup on the back or neck, thinning skin, and mood changes.
- Increased Blood Sugar (Hyperglycemia): Topical hydrocortisone can raise blood sugar levels, particularly with extensive use.
If you experience any side effects that are bothersome or do not go away, consult your healthcare provider.
Warnings and Precautions
Certain individuals and situations require caution or contraindicate the use of hydrocortisone cream.
Who Should Not Use Hydrocortisone?
- Individuals with known allergies to hydrocortisone or any other ingredients in the product.
- People with certain skin conditions such as acne, rosacea, cold sores, or untreated bacterial, fungal, or viral skin infections (e.g., chickenpox, shingles, syphilis, tuberculosis).
Special Considerations:
- Children: While generally safe for children aged 10 and over, those under 10 should only use it if advised by a doctor or pharmacist. Children may be more susceptible to systemic absorption and side effects.
- Pregnancy and Breastfeeding: Use only if clearly needed and recommended by a healthcare provider. It is not known if topical hydrocortisone can harm an unborn baby or pass into breast milk.
- Diaper Rash: Do not use OTC hydrocortisone for diaper rash unless directed by a doctor.
- Application Areas: Avoid applying to the eyes or mucous membranes.
- Skin Infections: If a skin infection develops or is present, an anti-infective therapy should be started before or concurrently with hydrocortisone.
- Long-Term Use: Prolonged use can lead to skin thinning, striae, and adrenal suppression.
- Occlusive Dressings: Do not use bandages, plastic wraps, or occlusive dressings unless directed by a doctor, as this increases absorption and the risk of side effects.
If your skin condition worsens or does not improve within 7 days of using an OTC product, stop use and consult a healthcare provider.
Drug Interactions
While topical hydrocortisone has minimal systemic absorption, it's important to inform your doctor about all medications and supplements you are using. Interactions are rare but can occur, especially if using other corticosteroid medications.
There are no known interactions between topical hydrocortisone and food or drinks. The effect of alcohol is unknown.
Missed Dose
If you miss a dose, apply it as soon as you remember. However, if it is almost time for your next scheduled dose, skip the missed dose and continue with your regular dosing schedule. Do not apply a double dose to compensate.
