Taking Avil, Nicip Cold, Cheston Cold, and Okacet Cold together is highly dangerous due to drug duplication, putting you at risk of paracetamol overdose and severe sedation. Please stop self-medicating immediately. Chronic allergies do not have a quick, permanent cure, but they can be controlled. You should consult an ENT specialist or allergist. They will likely recommend safer, targeted daily treatments like corticosteroid nasal sprays (e.g., Fluticasone) instead of oral multi-symptom cold pills. For a long-term, near-permanent solution, ask your doctor about Allergen Immunotherapy (allergy shots/drops), which desensitizes your immune system to specific allergy triggers over time.

For allergic rhinitis, the most effective treatments are daily nasal steroid sprays (like fluticasone) to reduce nasal inflammation, and non-drowsy oral antihistamines (like cetirizine, loratadine, or fexofenadine) to relieve sneezing, itching, and a runny nose. Saline nasal rinses are also highly recommended to clear out allergens. For severe congestion, short-term use (maximum 3-5 days) of decongestant nasal sprays can help, but prolonged use can worsen symptoms. Please consult a doctor or pharmacist to choose the safest option for you, especially if you have other health conditions.
