Itchy scalp can be a sign of many different conditions, including dandruff, eczema, psoriasis, and allergies. Over-the-counter antihistamines can help relieve the itchiness and other symptoms associated with these conditions.
There are many different types of antihistamines available over the counter, and it can be difficult to know which one is right for you. Be sure to read the labels carefully and consult with your healthcare provider if you have any questions.
Some of the most commonly used antihistamines for itchy scalp include diphenhydramine (Benadryl), cetirizine (Zyrtec), and hydroxyzine (Atarax).
Diphenhydramine is a sedating antihistamine that is most effective when taken at bedtime. It can cause drowsiness and dry mouth. Cetirizine is a nonsedating antihistamine that is generally well tolerated. Hydroxyzine is also a sedating antihistamine that can cause drowsiness and dry mouth.
Be sure to follow the instructions on the label and talk to your healthcare provider if you have any questions about which antihistamine is right for you.
The most popular antihistamines, such as Claritin and Zyrtec, are both effective at relieving itchiness. However, they work in different ways. Claritin works by blocking histamine receptors, while Zyrtec blocks histamine production.
So, which one is best for you? If you have a mild case of allergies, Claritin may be all you need. But if your allergies are more severe, Zyrtec may be a better option.
Of course, you should always check with your doctor before taking any medication. They can help you decide which antihistamine is right for you based on the severity of your allergies and any other medications you may be taking.
The best antihistamine for itchy scalp will depend on the underlying cause. For dandruff and seborrheic dermatitis, medicated shampoos containing ketoconazole or selenium sulfide are often effective. For psoriasis, treatments may include topical corticosteroids, calcipotriene, or tar products. If an allergic reaction is to blame, oral antihistamines can help to reduce symptoms.
If over-the-counter treatments do not provide relief, see a board-certified dermatologist for further evaluation and treatment.
