I'm sorry to hear that you're experiencing persistent itching despite using levocetirizine (an antihistamine), Forcan (an antifungal), and Keto soap. Itching all over the body for several days can be caused by various conditions, including allergies, infections, skin disorders, or systemic issues.

Here are some important points and steps you can take:

• Discontinue any new products that might be irritating your skin and avoid harsh soaps or hot water.
• Since levocetirizine and antifungal treatment have not helped, it is important to get a thorough evaluation by a dermatologist. They can examine your skin, possibly perform tests, and identify the underlying cause.
• Persistent generalized itching can sometimes be related to internal conditions such as liver, kidney, or thyroid problems, so your doctor may recommend blood tests.
• Meanwhile, keep your skin moisturized with gentle, fragrance-free emollients and avoid scratching to prevent skin damage.
• If you develop additional symptoms like fever, swelling, difficulty breathing, or severe rash, seek emergency care immediately.
