My boyfriend coughs a lot and has headaches. He takes flu pills every 4 hours. What should I do?

If your friend is experiencing a lot of coughing and headaches, it's important to make sure he is taking the right medication. Some flu medications may already contain ingredients found in cough syrups, so it's best to choose a cough syrup with different ingredients that won't interact with his current medication. It may also be helpful to use a product like Sinus Rinse twice a day for relief. Consult with a pharmacist to find the best syrup for his symptoms.
