A cough lasting 10 days despite antibiotics is often due to post-viral cough, asthma, or acid reflux, not infection. Night-time coughing with vomiting needs a doctor's review, as you may need inhalers, anti-reflux treatment, or a different evaluation instead of more antibiotics.

Generalized itching for two months without relief from cetirizine may be due to chronic urticaria, dry skin, allergies, thyroid/liver issues, or eczema. You may need a daily non-sedating antihistamine, moisturizers, and basic blood tests. A dermatologist can help identify the exact cause.

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

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.

Most sore throats and congestion are due to viral infections, which can take 3-5 days to improve. Keep hydrated, use warm salt-water gargles, and consider steam inhalation. If symptoms worsen, fever rises, or last beyond a week, see a doctor to rule out bacterial infection.

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.

For allergic rhinitis, adults usually take cetirizine 10 mg once daily as needed or for several weeks during allergy season. For a common cold, it may help temporarily with runny nose, but should be used only for a few days. Always follow your doctor's advice.

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.
