8 Reasons Your Cough Is Not Improving

Reason 7: Bacterial Infection

Sometimes, a cold can leave behind an unwelcome parting gift. When your airways are raw and irritated after a cold, it's easier for bacteria to invade. Bacteria can cause sinus infections, bronchitis, and pneumonia. If you have a fever or pain along with your lingering cough, a bacterial infection could be the reason. See your doctor, as you may need to take an antibiotic.

Reason 8: Your Blood Pressure Medicine

Do you take medicine for high blood pressure? If so, that may be why your cough won't quit. About 1 out of 5 people who take ACE inhibitors develop a chronic, dry cough as a side effect. If you have this side effect, talk to your doctor. Another drug may work better for you. ACE inhibitors include brands such as:

• Altace (ramipril)
• Capoten (captopril)
• Lotensin (benazepril)
• Prinivil, Zestril (lisinopril)
• Vasotec (enalapril)

If your cough isn’t getting better after a week, call your doctor. Together you can find out what’s causing your cough and make sure you get the right treatment.
