I'm trying to figure out if I should be worried about the side effects I'm experiencing. I started using seriflo250 as my pulmonologist prescribed due to some bronchi problems. I had a dry cough before, but now Im coughing more with sputum, and I suddenly got a runny nose, mild headache, and a fever around 100F. I used to smoke for about three years too. Is this normal, or is this something I should be concerned about?

It sounds like the medication is starting to open up your airways, which can sometimes lead to increased coughing and mucus production as your lungs begin to clear. However, the fever, headache, and worsening symptoms might indicate an infection or a reaction. It's important to contact your pulmonologist to discuss these new symptoms, especially considering your smoking history.
