I'm sorry to hear that you've been experiencing persistent itching. It can be quite uncomfortable, especially when it lasts for a couple of months and doesn't improve with cetirizine, an antihistamine commonly used to treat allergic reactions.

Here are some important points to consider:

• Itching (pruritus) lasting this long may have various causes beyond typical allergies, including skin conditions, systemic issues, or reactions to medications or environmental factors.
• Since cetirizine blocks histamine and you haven't found relief, it suggests that the cause might not be a simple allergic reaction or that another underlying condition could be involved.
• It is important to have a thorough evaluation by a dermatologist or a general physician who can:
  • Review your medical history and any other symptoms.
  • Perform a physical examination.
  • Possibly order blood tests or skin tests to identify causes such as infections, liver or kidney issues, or other systemic conditions.
• Avoid scratching as much as possible to prevent skin damage or infection.
• Keep your skin moisturized and avoid irritants like harsh soaps or detergents.

Recommendation: Please consult a dermatologist promptly to determine the underlying cause of your itching and to receive appropriate treatment tailored to your condition. If you develop additional symptoms like rash, swelling, difficulty breathing, or fever, seek urgent medical attention.To narrow down potential causes, we will need some more information.Please tell me your age and gender. I understand you've been experiencing itching all over your body for the last two months and haven't found relief with cetirizine.
