If your previous medication, Tusq-LS Syrup, didn't provide relief, the right alternative depends on your cough type. For a dry, hacking cough, a suppressant containing generic dextromethorphan or levodropropizine can help soothe the irritation. If you have a wet cough with mucus, an expectorant with ambroxol or guaifenesin will help clear your airways. Warm fluids and steam inhalation also offer safe, immediate relief. Because a severe, persistent cough requires proper evaluation, I highly recommend consulting a doctor to diagnose the underlying cause and get a targeted prescription.
