I would advise against combining cetirizine with the paracetamol, phenylephrine, and chlorpheniramine mixture. Both cetirizine and chlorpheniramine are antihistamines, and taking them together can cause excessive drowsiness, dry mouth, and dizziness. Additionally, since your cough has lasted nearly three weeks, these over-the-counter remedies may not address the underlying cause. A persistent cough of this duration warrants a proper evaluation by a doctor to find the exact cause and get you the right treatment.

You may take over-the-counter pain relievers such as paracetamol or ibuprofen to reduce fever and body aches. For a cold and cough, over-the-counter antihistamines such as cetirizine or loratadine, cough suppressants containing dextromethorphan, or expectorants like guaifenesin can help. Additionally, saline nasal sprays or drops and throat lozenges may soothe congestion and a sore throat. Seek medical advice if symptoms worsen, persist for more than a week, or if you develop difficulty breathing.

A severe headache for one week should not be ignored. Since your BP is normal, possible causes include Migraine, Tension headache, sinus issues, eye strain, sleep problems or any underlying medical condition. As the medicines you tried did not help, avoid further self-medication. Maintain proper hydration, regular sleep, and limit screen time. You should consult a doctor or neurologist for proper evaluation and appropriate treatment.

An antihistamine such as cetirizine can help with sneezing and a runny nose. Make sure to rest and drink plenty of warm fluids to support faster recovery. If your symptoms persist beyond 3-5 days, become severe, or if you develop a high fever or trouble breathing, please consult a doctor for proper assessment and treatment.

For a cold and sneezing, over-the-counter antihistamines such as cetirizine or loratadine can help relieve symptoms. Decongestants such as pseudoephedrine may reduce nasal congestion.
