Cetirizine can be taken before or after meals, as food does not affect it. The usual adult dose is 10 mg once daily, and it should not be taken more than one dose per day unless your doctor advises otherwise.

Common allergic skin conditions on the legs include eczema (dermatitis), contact allergy from soaps or fabrics, hives (urticaria), and insect-bite allergies. They usually cause redness, itching, rashes, or small bumps.

Simple viral infections like the common cold, which can produce body pains in addition to throat discomfort, are frequently the source of hand pain and sore throats. You can ease your discomfort by resting, drinking warm liquids, gargling with salt water, and taking a medication like paracetamol. It's best to contact a doctor to rule out a bacterial infection if you experience a high fever, severe throat pain, swelling, or symptoms that continue longer than a few days.

A persistent cold that interferes with your daily work is usually due to a viral infection, but it can also be worsened by allergies, sinus issues, or weak immunity. Most simple colds improve within a few days, but if symptoms last longer, you need to focus on supportive care; get adequate rest, drink plenty of warm fluids, and eat light, nutritious food to help your body recover. Steam inhalation and warm saltwater gargles can relieve nasal blockage and throat discomfort. You may use basic medicines like Paracetamol for fever or body aches and a suitable antihistamine for a runny nose, but avoid taking multiple medicines without advice. If you have thick yellow or green nasal discharge, severe headache, high fever, or symptoms lasting more than a week, it is better to consult a doctor to rule out a sinus infection or other causes. Maintaining good hygiene, avoiding cold exposure, and strengthening immunity with proper sleep and diet can help prevent recurrence.

If itching persists for months, twice-a-week cetirizine won't be enough. You may need daily antihistamines, trigger evaluation, or treatment for eczema, allergies, or urticaria. A dermatologist or allergist can identify the cause and guide safe long-term management.

Cetirizine is excreted in human milk. Therefore, you are recommended to avoid taking Cetirizine during breastfeeding unless you have contacted a doctor.
