How to Reduce Swelling with Cream | Topical Relief Facts

For the full breakdown, see our best Cream to Reduce Swelling guide.

Knowing how to reduce swelling with cream starts with understanding what these products can and cannot do. A topical anti-inflammatory works on the skin and the tissue just beneath it, which makes it a poor match for deep, unexplained, or rapidly spreading swelling. The two most common types are diclofenac gel for joint pain and hydrocortisone cream for itchy skin reactions. Each treats a different kind of problem, and using the wrong one for the wrong condition wastes time and can delay proper care.

Diclofenac Gel: The Arthritis Swelling Option

Diclofenac is a nonsteroidal anti-inflammatory drug (NSAID) in gel or solution form, and it targets pain and swelling from osteoarthritis, most often in the knee.

Application matters as much as the product itself. Apply diclofenac to clean, dry skin only, and never to skin that is broken, peeling, infected, or covered with a rash. After applying, do not cover the area with a bandage, and do not apply heat to the treated spot. Wash your hands immediately after use.

For the 1.5% prescription solution, the standard dosing for one knee follows a specific pattern:

• Clean and dry the skin around the knee.
• Apply 10 drops of solution at a time to the knee.
• Spread the drops around the front, back, and sides of the joint.
• Repeat until you have used 40 drops total for that knee.
• Wash and dry your hands thoroughly afterward.

Diclofenac is not meant for acute injuries like sprains; it is for ongoing inflammatory joint conditions.

Hydrocortisone Cream: For Bites and Skin Irritation

Hydrocortisone cream reduces swelling caused by minor inflammatory skin reactions, specifically insect bites and stings. It works by calming the immune response in the skin, which brings down both the swelling and the itch.

Squeeze a small amount onto a fingertip, apply it to the affected area, and rub it in until it disappears. Wash your hands afterward unless you are treating your hands themselves. Do not use hydrocortisone under a nappy or an airtight dressing, and if the area becomes weepy or shows signs of infection, stop using it and seek medical advice.

If the swelling has not improved in that window, the problem is likely not something a cream will fix.

What Creams Cannot Treat, and Safety Limits

If your leg, arm, or foot swells without an obvious cause, or if the swelling is warm, red, and painful, a cream is the wrong tool and a medical evaluation is the right one. The same goes for facial swelling or swelling that appears suddenly.

A few cautions apply across all topical anti-inflammatory products:

• Never apply these creams to open wounds, broken skin, or infected areas.
• Avoid covering treated skin with a bandage unless the label explicitly allows it.
• Watch for signs of infection, including weepy skin, increasing redness, or fever.
