Due to COVID, I have a lot of secretions and a productive cough?

It is recommended to maintain good nasal hygiene to prevent mucus from dripping down the throat. Drinking plenty of fluids, either hot or cold, can also help in relieving the symptoms of cough. Syrups for cough may not be very effective, so it is advisable to focus on hydration and using throat lozenges like Fisherman's Friend or Halls.
