Insect Bites: 5 Mistakes That Worsen Itching

Reem Qasim: Insect bites are common during the summer, often accompanied by intense itching that can worsen due to certain incorrect behaviors. Below are the key tips for soothing the skin and the mistakes to avoid to minimize persistent itching, according to a report published in Notre Temps magazine.

1. Continuous scratching: This is undoubtedly the most common mistake. Scratching intensifies the itch and keeps it going. Pharmacist Arnaud Centorel explains that the bite triggers histamine release, causing itching and irritation, while repeated scratching stimulates nerve fibers and increases the itch. Additionally, nails can scratch the skin, raising the risk of secondary infection.

2. Using heat: It is not recommended to take a very hot shower or apply a heat source to the bite area. The pharmacist emphasizes: “Anything that causes blood vessels to dilate will increase inflammation around the bite and worsen the itching.” Conversely, cold is a valuable ally. The pharmacist clarifies: “Applying cold compresses or ice cubes wrapped in a cloth has a vasoconstrictive and analgesic effect. It reduces inflammation and soothes itching.”

3. Delaying treatment for the bite: Some people postpone first aid, hoping the itching will subside on its own. However, prolonged waiting may allow the venom to spread further into the tissues, potentially increasing the inflammatory response and itching. The optimal solution is to clean the area quickly with soap and water, then apply appropriate treatment if necessary.

4. Relying on home remedies: Toothpaste, vinegar, and lemon are commonly recommended by the general public, but they are strongly discouraged. The pharmacist warns against them, stating: “Toothpaste contains many irritating and abrasive substances that may do more harm than good.” The same applies to vinegar and lemon: “These acidic products may further damage skin already compromised by the bite.”

5. Using an unsuitable product: Using certain antiseptics without a medical prescription can irritate the skin. If itching persists, it is recommended to use antihistamine creams for 48 to 72 hours, while topical corticosteroids and zinc-containing creams may help reduce inflammation and irritation. In more severe cases, a doctor may prescribe an antihistamine such as cetirizine.

◄ What to do if bitten by an insect? To reduce itching and speed up recovery, the following steps are recommended:

• Clean the bite area with soap and water.

• Apply a cold compress or an ice cube wrapped in a cloth.

• Use an appropriate topical treatment if needed.

• Avoid scratching the bite area as much as possible.

◄ When to consult a doctor? The expert says: “You should consult a doctor if redness or swelling spreads rapidly, or if severe pain, pus, or crusts appear, as these signs may indicate a secondary infection.” Caution is also advised if the bite is near a mucous membrane, such as the mouth, lips, or genital area, or if it is accompanied by fever, headache, general malaise, or unusual fatigue. Finally, facial or throat swelling, difficulty breathing, general malaise, or low blood pressure may indicate a severe allergic reaction. The pharmacist concludes: “This is anaphylaxis, a medical emergency requiring immediate care.”
