Yes, you can take Sinarest New Tablet to help relieve cold symptoms. It contains Paracetamol (antipyretic) to reduce fever, Phenylephrine (decongestant) to clear a blocked nose, and Chlorpheniramine (antihistamine) to help with sneezing or a runny nose. Follow the instructions on the pack or your doctor?s advice, and do not take more than the recommended dose. If your symptoms persist for more than a few days or worsen, please consult your doctor.

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.

Your symptoms suggest a viral infection or flu, which may take several days to improve. Continue to rest, drink warm fluids, do steam inhalation, and take medicines as advised by your doctor. If symptoms persist beyond a few more days, worsen, or fever increases, consult your doctor for proper evaluation and treatment.

A runny nose caused by changes in temperature is usually mild and often resolves on its own within a few days. You may use a saline nasal spray to relieve congestion and keep your nasal passages moist. If symptoms are bothersome, over-the-counter antihistamines (such as cetirizine) or decongestants (such as oxymetazoline) may help. Stay well hydrated and avoid sudden exposure to cold air.

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. Pain relievers like acetaminophen or ibuprofen can ease fever and body aches, and cough suppressants such as dextromethorphan can help with a cough. Make sure to get adequate rest, drink plenty of fluids, and consult a doctor if symptoms persist or worsen.

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.
